本申请实施例提供的图像拍摄方法，可以应用于在使用平板、笔记本电脑等电子设备中运行一些应用时，获取图片/视频的场景中。应理解，视频通常由多个图像帧组成，每个图像帧即为一张图像。因此，为了便于说明，在下文中，将图片/视频简称为图像。The image capture method provided in the embodiment of the present application can be applied to the scene of obtaining pictures/videos when running some applications in electronic devices such as tablets and laptops. It should be understood that a video is usually composed of multiple image frames, and each image frame is an image. Therefore, for the sake of convenience, in the following, pictures/videos are referred to as images.
以获取图片为例，上述一些应用可以是任意有插入图片、编辑图片、发送图片、扫描图片等功能的应用，在这些应用的运行过程中，可以获取图片并对其进行插入、编辑、发送、扫描等处理。Taking the acquisition of pictures as an example, the above-mentioned applications may be any application with functions such as inserting pictures, editing pictures, sending pictures, scanning pictures, etc. During the operation of these applications, pictures may be acquired and inserted, edited, sent, scanned, etc.
示例性的，文字处理系统(Word Processing System，WPS)、office、备忘录等文档编辑应用都有插入图片的功能，则上述一些应用可以为WPS、office、备忘录等文档编辑应用。For example, document editing applications such as word processing system (WPS), office, and memo all have the function of inserting pictures, so some of the above-mentioned applications may be document editing applications such as WPS, office, and memo.
又示例性的，购物应用有扫描商品图片的功能，银行应用有扫描证件图片的功能，则上述一些应用可以为购物应用、银行应用。As another example, a shopping application has a function of scanning product images, and a banking application has a function of scanning ID images, so some of the above applications may be shopping applications and banking applications.
再示例性的，视频剪辑应用、图片处理应用都有编辑图片的功能，则上述一些应用可以为视频剪辑应用、图片处理应用。As another example, a video editing application and a picture processing application both have the function of editing pictures, so some of the above applications may be video editing applications and picture processing applications.
还示例性的，聊天应用具有发送图片的功能，则上述一些应用可以为聊天应用。Also exemplarily, if a chat application has a function of sending pictures, some of the above applications may be chat applications.
在下文中，为了便于说明，将上述一些应用统称为目标应用(也可以称为第一应用)。In the following, for the sake of convenience, the above applications are collectively referred to as target applications (also referred to as first applications).
下面以目标应用是文档编辑应用为例，来示例性的说明本申请的应用场景：The following takes the target application as a document editing application as an example to illustrate the application scenario of this application:
参见图1，笔记本电脑在运行文档编辑应用的过程中，可以显示图1所示的界面101，界面101中包括编辑的文档内容，如“旅行日记……”，还包括插入图片的控件102。笔记本电脑可以接收用户对控件102的点击操作，响应于用户对控件102的点击操作，笔记本电脑则获取图片插入到文档内容中。本申请实施例提供的图像拍摄方法，可以应用于用户点击控件102后，获取图片的场景中。Referring to FIG. 1 , when a laptop computer is running a document editing application, an interface 101 shown in FIG. 1 may be displayed. The interface 101 includes the edited document content, such as “travel diary…”, and also includes a control 102 for inserting a picture. The laptop computer may receive a user click operation on the control 102, and in response to the user click operation on the control 102, the laptop computer obtains the picture and inserts it into the document content. The image shooting method provided in the embodiment of the present application may be applied to a scenario in which a user obtains a picture after clicking the control 102.
在一些常规技术中，在上述获取图片的场景中，电子设备只能获取本地中已经存储的图片。示例性的，笔记本电脑响应于用户对图1中所示的界面101中控件102的点击操作，可以显示图1所示的界面103，界面103中包括对话框104。在对话框104中，用户可以从笔记本电脑的本地已经存储的图片中选择图片插入到正在编辑的文档中。In some conventional technologies, in the above-mentioned scenario of acquiring pictures, the electronic device can only acquire pictures that have been stored locally. Exemplarily, in response to a user clicking on a control 102 in the interface 101 shown in FIG. 1 , the laptop computer can display the interface 103 shown in FIG. 1 , and the interface 103 includes a dialog box 104. In the dialog box 104, the user can select a picture from the pictures that have been stored locally on the laptop computer and insert it into the document being edited.
然而，在一些情况下，当前运行该目标应用的电子设备(如图1中的笔记本电脑)中并没有存储用户所需的图片，因此不能满足用户获取图片的需求。However, in some cases, the electronic device (such as the laptop in FIG. 1 ) currently running the target application does not store the pictures required by the user, and thus cannot meet the user's need to obtain pictures.
在另一些常规技术中，电子设备可以支持直接通过调用本地相机来拍摄图片，然后获取本地相机拍摄的图片。示例性的，笔记本电脑响应于用户对图1所示的界面101中控件102的点击操作，可以显示图1中所示的界面103，界面103中包括对话框104。此时，用户可以先使用笔记本电脑中的相机拍摄得到图片，然后在对话框104中查找到相应的图片并插入到正在编辑的文档中。In other conventional technologies, the electronic device can support taking pictures directly by calling a local camera, and then obtain the pictures taken by the local camera. Exemplarily, in response to the user clicking the control 102 in the interface 101 shown in FIG. 1, the laptop can display the interface 103 shown in FIG. 1, and the interface 103 includes a dialog box 104. At this time, the user can first use the camera in the laptop to take pictures, and then find the corresponding pictures in the dialog box 104 and insert them into the document being edited.
然而，在一些情况中，当前运行该目标应用的电子设备可能并不能便捷的拍摄得到合适的图片。一种典型的可能为：平板、笔记本电脑等电子设备的体积较大或摄像头能力有限等原因，将导致拍照灵活性通常较低或质量不佳，无法便捷地拍摄得到理想的图片。However, in some cases, the electronic device currently running the target application may not be able to conveniently take suitable pictures. A typical possibility is that the electronic devices such as tablets and laptops are large in size or have limited camera capabilities, which will result in low flexibility or poor quality of taking pictures, and it is not possible to conveniently take ideal pictures.
由此可见，如果在上述获取图像的场景中，电子设备只能使用本地相机来拍摄图像，或者获取本地中已经存储的图像，则极有可能无法满足目标应用对图像的需求。It can be seen that if in the above-mentioned image acquisition scenario, the electronic device can only use the local camera to capture images, or obtain images that have been stored locally, it is very likely that the image requirements of the target application cannot be met.
基于此，本申请实施例提供了一种图像拍摄方法，可以应用于上述获取图像的场景中。其中，在电子设备获取图像的情况下，可以调用其它设备拍摄图像。然后，其它设备将拍摄得到的图像返回给电子设备。如此，该方法不仅可以打破只能从本地(包括本地相机或者本地图库)获取图像的局限。尤其是对于平板、笔记本电脑等拍摄灵活性较差的电子设备，可以使用调用其它电子设备来拍摄，可以为用户提供便捷、舒适的图像拍摄体验。Based on this, an embodiment of the present application provides an image capture method that can be applied to the above-mentioned scene of acquiring images. Among them, when an electronic device acquires an image, other devices can be called to capture the image. Then, the other devices return the captured image to the electronic device. In this way, the method can not only break the limitation of only being able to acquire images locally (including local cameras or local galleries). Especially for electronic devices with poor shooting flexibility such as tablets and laptops, other electronic devices can be called to shoot, which can provide users with a convenient and comfortable image capture experience.
本申请实施例还提供了一种通信系统，参见图2，通信系统包括第一设备(如图2所示的笔记本电脑210)和至少一个第二设备(如图2所示的手机220、平板230)。An embodiment of the present application also provides a communication system. Referring to FIG. 2 , the communication system includes a first device (a laptop computer 210 as shown in FIG. 2 ) and at least one second device (a mobile phone 220 and a tablet computer 230 as shown in FIG. 2 ).
其中，第一设备中安装有目标应用，在第一设备运行目标应用的过程中，可能产生获取图像的需求。第二设备中包括实现远程的拍摄调用和图像分发功能的应用(可简称为远程相机)，远程相机可以接收第一设备的调用请求，并将第二设备的系统相机拍摄得到的图像分发给第一设备。The first device has a target application installed in it, and when the first device runs the target application, it may need to obtain an image. The second device includes an application that implements remote shooting call and image distribution functions (referred to as a remote camera for short), and the remote camera can receive the call request of the first device and distribute the image captured by the system camera of the second device to the first device.
第一设备和第二设备之间可以通信连接。通信连接包括互联网连接。通过互联网连接，第二设备可以向第一设备同步(即发送)其支持远程相机的功能，以便于第一设备发现第二设备的远程相机并调用。以及，通信连接还包括近场通信连接。通过近场通信连接，第一设备可以点对点的向第二设备发送调用请求，以及第二设备可以将拍摄得到的图像传输给第一设备。其中，近场通信包括蓝牙、无线保真(Wireless Fidelity，WIFI)、近距离无线通信(Near Field Communication，NFC)等。The first device and the second device can be connected in communication. The communication connection includes an Internet connection. Through the Internet connection, the second device can synchronize (i.e., send) its remote camera support function to the first device, so that the first device can discover and call the remote camera of the second device. And, the communication connection also includes a near-field communication connection. Through the near-field communication connection, the first device can send a call request to the second device point-to-point, and the second device can transmit the captured image to the second device. To the first device. Among them, near field communication includes Bluetooth, Wireless Fidelity (Wireless Fidelity, WIFI), Near Field Communication (Near Field Communication, NFC) and the like.
需要说明的是，本申请实施例中，与互联网连接相比：通过近场通信传输调用请求以及图像数据等，一方面可以通过点对点的方式来传输信息，更有利于保证信息安全。另一方面，如果使用蓝牙或者NFC等无需依赖网络的近场通信技术，信息传输速率不会受到网络因素的影响，可以更稳定快速的传输信息；而且，即使第一设备和/或第二设备没有连接网络，也可以实现远程相机的调用以及图像数据的传输。It should be noted that, in the embodiments of the present application, compared with Internet connection: transmitting call requests and image data through near-field communication, on the one hand, can transmit information in a point-to-point manner, which is more conducive to ensuring information security. On the other hand, if near-field communication technologies such as Bluetooth or NFC that do not rely on the network are used, the information transmission rate will not be affected by network factors, and information can be transmitted more stably and quickly; moreover, even if the first device and/or the second device are not connected to the network, the remote camera call and image data transmission can be realized.
应注意，第一设备和第二设备之间可以不同时建立互联网连接和近场通信连接。例如，在调用远程相机的过程中，则可以仅建立近场通信连接，而无需建立互联网连接。It should be noted that the first device and the second device may not establish an Internet connection and a near field communication connection at the same time. For example, in the process of calling a remote camera, only a near field communication connection may be established without establishing an Internet connection.
在一些示例中，第一设备和第二设备中可以登录有相同的系统级别的用户账号，如相同的账号、相同的账号等。应理解，登录相同用户账号的同账号设备(如第一设备和第二设备)之间，可以通过身份认证，加入到同一信任环中。从而可以仅在信任环内进行信息交互，如同步远程相机的能力、传输调用请求、传输图像等，保证设备安全。In some examples, the first device and the second device may have the same system-level user account logged in, such as the same Account number, same Accounts, etc. It should be understood that devices with the same account (such as the first device and the second device) that log in to the same user account can be added to the same trust ring through identity authentication. Therefore, information interaction can be performed only within the trust ring, such as synchronizing the capabilities of remote cameras, transmitting call requests, transmitting images, etc., to ensure device security.
上述第一设备和第二设备，仅仅只是基于电子设备在获取图片的场景中，扮演的不同功能角色来划分的。其中，第一设备为图像的需求设备，第二设备为图像的提供设备。应理解，同一电子设备，在一些场景中，可以作为第一设备，在另一些场景中，也可以作为第二设备。示例性的，如果上述图2中的手机220或者平板230从其它设备获取图像，即为图像的需求设备，其也可以作为第一设备。如果上述图2中的笔记本电脑210具有远程相机能力，其也可以作为图像的提供设备，即作为第二设备。The above-mentioned first device and second device are only divided based on the different functional roles played by the electronic device in the scene of acquiring pictures. Among them, the first device is an image demanding device, and the second device is an image providing device. It should be understood that the same electronic device can be used as a first device in some scenarios and as a second device in other scenarios. Exemplarily, if the mobile phone 220 or tablet 230 in Figure 2 above acquires images from other devices, that is, it is an image demanding device, it can also be used as a first device. If the laptop computer 210 in Figure 2 above has a remote camera capability, it can also be used as an image providing device, that is, as a second device.

第二设备的应用程序层中还包括远程相机，远程相机用于接收第一设备的调用，并调用第二设备的系统相机拍摄图像后回传给第一设备。也就是说，与系统相机相比，远程相机支持调用者的编排传输，可以决定将图像传输给谁。The application layer of the second device also includes a remote camera, which is used to receive the call from the first device and call the system camera of the second device to take an image and then transmit it back to the first device. In other words, compared with the system camera, the remote camera supports the caller's orchestration transmission and can decide to whom to transmit the image.
应用程序框架层为应用程序层的应用程序提供应用编程接口(application programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。The application framework layer provides application programming interface (API) and programming framework for the applications in the application layer. The application framework layer includes some predefined functions.
应用程序框架层可以包括通知管理器、窗口管理器、资源管理器、内容提供器和视图系统等。The application framework layer may include a notification manager, a window manager, a resource manager, a content provider, and a view system, etc.
通知管理器使应用程序可以在状态栏中显示通知信息，可以用于传达告知类型的消息，可以短暂停留后自动消失，无需用户交互。比如通知管理器被用于告知下载完成，消息提醒等。通知管理器还可以是以图表或者滚动条文本形式出现在系统顶部状态栏的通知，例如后台运行的应用程序的通知，还可以是以对话窗口形式出现在屏幕上的通知。例如在状态栏提示文本信息、发出提示音、终端设备振动、指示灯闪烁等。窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏、锁定屏幕、触摸屏幕、拖拽屏幕、截取屏幕等。资源管理器为应用程序提供各种资源，例如本地化字符串、图标、图片、布局文件、视频文件等等。内容提供器用于在不同的应用程序之间实现数据共享的功能，允许一个程序访问另一个程序中的数据，同时还能保证被访问的数据的安全性。视图系统可以负责应用程序的界面绘制和事件处理。The notification manager allows applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify that a download is complete. The notification manager can also be a notification that appears in the top status bar of the system in the form of a chart or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in the status bar, a prompt sound is issued, the terminal device vibrates, the indicator light flashes, etc. The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, touch the screen, drag the screen, capture the screen, etc. The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc. The content provider is used to implement data sharing between different applications, allowing one program to access the data in another program while ensuring the security of the accessed data.

以及，应用程序框架层还可以包括接续服务、应用鉴权服务、通信服务以及设备管理服务(Profile)。Furthermore, the application framework layer may also include connection services, application authentication services, communication services, and device management services (Profile).
接续服务为目标应用提供近场设备发现感知，以及提供数据和文件发送的能力。示例性的，接续服务可以负责目标应用的接入。以及，在目标应用接入接续服务后，接续服务还可以负责为目标应用查询可以调用并进行拍摄的设备(即下文中的可用设备)，跨设备传输调用请求、图像等数据。The connection service provides the target application with near-field device discovery awareness and the ability to send data and files. For example, the connection service can be responsible for accessing the target application. And, after the target application accesses the connection service, the connection service can also be responsible for querying the target application for devices that can be called and shot (i.e., available devices below), and transmitting call requests, images and other data across devices.
应用鉴权服务可以负责应用的合法性校验，如校验应用的身份和权限。示例性的，应用鉴权模块可以负责校验请求接入接续服务的目标应用的合法性，在确认目标应用合法的情况下，才允许目标应用接入接续服务。从而避免为非法应用提供调用远程相机进行拍摄的服务。The application authentication service can be responsible for checking the legitimacy of the application, such as checking the identity and permissions of the application. For example, the application authentication module can be responsible for checking the legitimacy of the target application requesting access to the continuation service. Only when the target application is confirmed to be legitimate, the target application is allowed to access the continuation service. This avoids providing illegal applications with the service of calling the remote camera for shooting.
通信服务，如的智能互联服务(Magic Link)，可用于实现跨设备间的数据传输，同账号设备的安全认证与账号鉴权、设备的自发现与自组网等。示例性的，通过通信服务，第一设备可以发现位于近场的第二设备并验证第二设备的身份，并在验证第二设备是可信任的设备(即登录相同的用户账号的设备)之后，在第一设备和第二设备之间传输调用请求以及传输图像等。Communication services such as The smart interconnection service (Magic Link) can be used to realize data transmission across devices, security authentication and account authentication of devices with the same account, self-discovery and self-organizing network of devices, etc. For example, through the communication service, the first device can discover the second device in the near field and verify the identity of the second device, and after verifying that the second device is a trusted device (i.e., a device logged in with the same user account), transmit call requests and images between the first device and the second device.
设备管理服务可视为设备间同步数据的数据库，数据库可以记录同账号设备具有的能力、能力被占用的情况、近场设备的信息等。示例性的，第一设备的设备管理服务可以记录第二设备具有远程相机的能力、该远程相机的能力被占用的情况、近场通信范围内的设备等信息。The device management service can be regarded as a database for synchronizing data between devices, and the database can record the capabilities of devices with the same account, the situation in which the capabilities are occupied, information about near-field devices, etc. For example, the device management service of the first device can record information such as the remote camera capability of the second device, the situation in which the remote camera capability is occupied, and the devices within the near-field communication range.
runtime包括核心库和虚拟机。runtime负责系统的调度和管理。 The runtime includes the core library and the virtual machine. The runtime is responsible for Scheduling and management of the system.
核心库包含两部分：一部分是java语言调用的功能函数，另一部分是安卓的核心库。The core library consists of two parts: one is the function called by Java language, and the other is the core library of Android.
应用程序层和应用程序框架层运行在虚拟机中。虚拟机将应用程序层和应用程序框架层的java文件执行为二进制文件。虚拟机用于执行对象生命周期的管理，堆栈管理，线程管理，安全和异常的管理，以及垃圾回收等功能。The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.
系统库可以包括多个功能模块。例如：媒体库(Media Libraries)、函数库(Function Libraries)图形处理库(例如：OpenGL ES)等。The system library can include multiple functional modules, such as media libraries, function libraries, graphics processing libraries (such as OpenGL ES), etc.

图形处理库用于实现图形绘图、图像渲染、合成和图层处理等。The graphics processing library is used to implement graphics drawing, image rendering, synthesis and layer processing.
硬件抽象层是介于内核层和Android runtime之间的抽象出来的一层结构。硬件抽象层可以是对硬件驱动的一个封装，为上层应用的调用提供统一接口。硬件抽象层可以包括蓝牙模块、WIFI模块等。示例性的，蓝牙模块和WIFI模块可以屏蔽内核层中蓝牙驱动和WIFI驱动的具体硬件实现细节，上层应用在不必知道内核层硬件驱动的具体实现方式的情况下就可以通过调用接口实现蓝牙功能和WIFI功能。The hardware abstraction layer is an abstract structure between the kernel layer and the Android runtime. The hardware abstraction layer can be a package of the hardware driver, providing a unified interface for the upper-layer application to call. The hardware abstraction layer can include Bluetooth modules, WIFI modules, etc. For example, the Bluetooth module and the WIFI module can shield the specific hardware implementation details of the Bluetooth driver and the WIFI driver in the kernel layer, and the upper-layer application can implement the Bluetooth function and the WIFI function by calling the interface without knowing the specific implementation method of the kernel-layer hardware driver.
内核层是硬件和软件之间的层。内核层可以包括显示驱动、摄像头驱动、音频驱动、蓝牙驱动、WiFi驱动、通用串行总线(Universal Serial Bus，USB)驱动、中央处理器驱动等。The kernel layer is the layer between hardware and software. The kernel layer can include display drivers, camera drivers, audio drivers, Bluetooth drivers, WiFi drivers, Universal Serial Bus (USB) drivers, CPU drivers, etc.
在一些实施例中，通信服务(如Magic Link)可以通过蓝牙驱动以及WiFi驱动等相关近场通信模块进行跨设备间的连接，实现设备的自发现与自组网。In some embodiments, communication services (such as Magic Link) can connect across devices through related near-field communication modules such as Bluetooth drivers and WiFi drivers, thereby achieving self-discovery and self-organizing networking of devices.
本申请实施例这里将结合图4A和图4B的软件架构，对图像拍摄方法的实现进行说明：在第一设备的目标应用接入接续服务后，如果目标应用需要获取图像，目标应用可以依次通过第一设备的接续服务、设备管理服务查询到可用设备，可用设备中包括第二设备。然后，目标应用依次通过第一设备的接续服务、通信服务向可用设备中的第二设备发送调用请求，请求调用第二设备的远程相机。依次经过第二设备的通信服务、接续服务，第二设备的接续服务接收到调用请求。第二设备的接续服务启动第二设备的远程相机，以调用第二设备的系统相机拍摄图像。在第二设备的系统相机拍摄完图像之后，可以经过第二设备的远程相机、接续服务、通信服务，以及第一设备的通信服务、接续服务，最后传输给第一设备的目标应用。这样，第一设备的目标应用则获取到由第二设备拍摄得到的图像，打破只能从本地(包括本地相机或者本地图库)获取图像的局限，更加灵活的满足电子设备对图像的需求。The embodiment of the present application will be combined with the software architecture of Figures 4A and 4B to illustrate the implementation of the image shooting method: after the target application of the first device accesses the continuation service, if the target application needs to obtain an image, the target application can query the available devices through the continuation service and device management service of the first device in sequence, and the available devices include the second device. Then, the target application sends a call request to the second device in the available devices through the continuation service and communication service of the first device in sequence, requesting to call the remote camera of the second device. After passing through the communication service and continuation service of the second device in sequence, the continuation service of the second device receives the call request. The continuation service of the second device starts the remote camera of the second device to call the system camera of the second device to shoot an image. After the system camera of the second device shoots the image, it can be transmitted to the target application of the first device through the remote camera, continuation service, communication service of the second device, and the communication service and continuation service of the first device. In this way, the target application of the first device obtains the image shot by the second device, breaking the limitation of only being able to obtain images from the local (including the local camera or the local gallery), and more flexibly meeting the image needs of the electronic device.
至此，需要说明的是，上述图4A和图4B均以AndroidTM系统为例，说明了第一设备和第二设备的软件架构。实际中，上述第一设备和/或第二设备的操作系统也可以是WindowsTM系统。在WindowsTM操作系统中，应用层(如电脑管家应用)中还可以集成上述应用程序框架层中接续服务、应用鉴权服务、通信服务、设备管理服务，以及硬件抽象层中蓝牙模块、WIFI模块的功能。应用层通过调用蓝牙驱动或者WIFI驱动，完成与对端的近场通信，实现设备间的数据传输。At this point, it should be noted that the above-mentioned Figures 4A and 4B both take the AndroidTM system as an example to illustrate the software architecture of the first device and the second device. In practice, the operating system of the above-mentioned first device and/or the second device may also be a WindowsTM system. In the WindowsTM operating system, the application layer (such as a computer housekeeper application) may also integrate the connection service, application authentication service, communication service, device management service in the above-mentioned application framework layer, and the functions of the Bluetooth module and the WIFI module in the hardware abstraction layer. The application layer completes the near-field communication with the opposite end by calling the Bluetooth driver or the WIFI driver to realize data transmission between devices.

针对任一设备，如果该设备和笔记本电脑210中登录有相同的用户账号、且该设备支持远程相机，则该设备可以通过互联网向笔记本电脑210同步其具有远程相机的能力。相应的，笔记本电脑210则可以记录该设备为支持远程相机的设备。For any device, if the same user account is logged in to the device and the laptop 210, and the device supports remote cameras, the device can synchronize its remote camera capability to the laptop 210 via the Internet. Accordingly, the laptop 210 can record the device as a device that supports remote cameras.
示例性的，参见图6A，笔记本电脑210、手机220和平板230中登录的用户账号均为账号a，属于同账号设备，且手机220和平板230都支持远程相机。那么，手机220和平板230可以将其具有远程相机的能力的信息通过互联网上报到云端。云端可以将手机220和平板230具有远程相机的能力的信息下发给所有的同账号设备，如将手机220具有远程相机的能力的信息下发给笔记本电脑210和平板230，将平板230具有远程相机的能力的信息下发给笔记本电脑210和手机220。这样，笔记本电脑210可以获取到手机220和平板230具有远程相机的能力的信息，则可以记录如下信息“平板230，支持远程相机；手机220，支持远程相机”。例如，笔记本电脑210可以数组或者矩阵等形式记录“平板230，支持远程相机；手机220，支持远程相机”，本申请实施例对此不作具体限定。For example, referring to FIG. 6A , the user accounts logged in on the laptop 210 , the mobile phone 220 , and the tablet 230 are all Account a belongs to the same account device, and both the mobile phone 220 and the tablet 230 support remote cameras. Then, the mobile phone 220 and the tablet 230 can report the information that they have the ability of remote cameras to the cloud through the Internet. The cloud can send the information that the mobile phone 220 and the tablet 230 have the ability of remote cameras to all the devices with the same account, such as sending the information that the mobile phone 220 has the ability of remote cameras to the laptop 210 and the tablet 230, and sending the information that the tablet 230 has the ability of remote cameras to the laptop 210 and the mobile phone 220. In this way, the laptop 210 can obtain the information that the mobile phone 220 and the tablet 230 have the ability of remote cameras, and can record the following information "Tablet 230, supports remote cameras; mobile phone 220, supports remote cameras". For example, the laptop 210 can record "Tablet 230, supports remote cameras; mobile phone 220, supports remote cameras" in the form of an array or matrix, etc., and the embodiments of the present application do not specifically limit this.
以及，笔记本电脑210发现在线设备的过程可以包括：And, the process of the laptop computer 210 discovering the online device may include:
针对任一设备，如果笔记本电脑210检测到该设备在笔记本电脑210的近场通信范围内，且验证该设备中登录的用户账号与笔记本电脑210中登录的用户账号相同，笔记本电脑210则可以将该设备标记为在线设备。例如，笔记本电脑210和该设备都打开了蓝牙，并且笔记本电脑210通过蓝牙扫描到了该设备，或者，该设备与笔记本电脑210连接同一Wifi，则可以确定该设备在笔记本电脑210的近场通信范围内，在此基础上，笔记本电脑210和该设备之间通过近场交换身份信息验证两者都登录有相同的用户账号，则可以确定该设备为在线设备。For any device, if the laptop 210 detects that the device is within the near field communication range of the laptop 210 and verifies that the user account logged in to the device is the same as the user account logged in to the laptop 210, the laptop 210 can mark the device as an online device. For example, if the laptop 210 and the device both have Bluetooth turned on, and the laptop 210 scans the device through Bluetooth, or the device and the laptop 210 are connected to the same Wifi, it can be determined that the device is within the near field communication range of the laptop 210. On this basis, the laptop 210 and the device exchange identity information through near field to verify that both are logged in with the same user account, and the device can be determined to be an online device.
以近场通信是蓝牙通信为例，参见图6B，笔记本电脑210通过蓝牙扫描到手机220、平板230和手机610，且笔记本电脑210、手机220、平板230和手机610都登录有用户账号a，笔记本电脑210则可以标记手机220、平板230和手机610为在线设备。Taking the case where the near field communication is Bluetooth communication as an example, see Figure 6B. The laptop computer 210 scans the mobile phone 220, the tablet computer 230 and the mobile phone 610 via Bluetooth, and the laptop computer 210, the mobile phone 220, the tablet computer 230 and the mobile phone 610 are all logged in with the user account a. The laptop computer 210 can then mark the mobile phone 220, the tablet computer 230 and the mobile phone 610 as online devices.
经过S501，笔记本电脑210发现支持远程相机的设备和在线设备之后，响应于用户获取图片的操作(如点击图7A所示界面701中“图片”702的操作)，笔记本电脑210可以将支持远程相机的在线设备，确定为可用设备，以用于拍摄图像。示例性的，图6A中，支持远程相机的设备为手机220和平板230，图6B中，在线设备为手机220、平板230和手机610，那么，笔记本电脑210可以将手机220和平板230确定为可用设备以用于拍摄图像。After S501, the laptop computer 210 finds the device and online device supporting the remote camera, and in response to the user's operation of obtaining a picture (such as clicking the "Picture" 702 in the interface 701 shown in FIG. 7A), the laptop computer 210 can determine the online device supporting the remote camera as an available device for capturing an image. For example, in FIG. 6A, the devices supporting the remote camera are the mobile phone 220 and the tablet 230, and in FIG. 6B, the online devices are the mobile phone 220, the tablet 230, and the mobile phone 610, so the laptop computer 210 can determine the mobile phone 220 and the tablet 230 as available devices for capturing an image.
需要说明的是，上述S501是持续的。在开机后，笔记本电脑210会持续不断的发现支持远程相机的设备和在线设备。例如，有新的设备与笔记本电脑210登录相同的用户账号，且支持远程相机，则该新的设备会被笔记本电脑210发现为支持远程相机的设备。又例如，已经被发现为支持远程相机的设备，其不再提供远程相机的能力，则笔记本电脑210会将该设备从支持远程相机的设备中剔除。再例如，有新的设备进入笔记本电脑210的近场通信范围内，且该新的设备与笔记本电脑210登录相同的用户账号，则该新的设备会被笔记本电脑210发现为在线设备。还例如，已经被发现为在线设备的设备，其超出笔记本电脑210的近场通信范围，或者切换登录的用户账号，笔记本电脑210则会将该设备从在线设备中剔除。It should be noted that the above S501 is continuous. After booting, the laptop 210 will continuously discover devices and online devices that support remote cameras. For example, if a new device logs in to the same user account as the laptop 210 and supports remote cameras, the new device will be discovered by the laptop 210 as a device that supports remote cameras. For another example, if a device that has been discovered to support remote cameras no longer provides the ability of remote cameras, the laptop 210 will remove the device from the devices that support remote cameras. For another example, if a new device enters the near-field communication range of the laptop 210, and the new device logs in to the same user account as the laptop 210, the new device will be discovered by the laptop 210 as an online device. For another example, if a device that has been discovered to be an online device exceeds the near-field communication range of the laptop 210, or switches the logged-in user account, the laptop 210 will remove the device from the online devices.

In response to the user's click operation on the “picture” 702 in the interface 701 , the laptop computer 210 can display the interface 706 shown in FIG. 7B , and the interface 706 includes two options, “local gallery” and “remote camera” 707 . The “local gallery” can be used to trigger the acquisition of images from the local gallery of the laptop computer 210 . The “remote camera” 707 can be used to trigger the remote camera of other devices (such as the mobile phone 220 ) to capture images. In this example, the acquisition control also includes the “remote camera” 707 in the interface 706 shown in FIG. 7B , and the acquisition operation also includes the user's click operation on the “remote camera” 707 in the interface 706 . That is, the acquisition operation includes multiple operations of the user.
当然，获取操作并不以此为限。在另一些实施例中，获取操作还可以是用户对目标应用的应用界面的预设手势，如滑动、长按等手势。或者，获取操作还可以是用户输入预设语音的操作，如输入“插入图片”的语音。Of course, the acquisition operation is not limited to this.

Compared with the interface 103, the interface 703 not only includes the option of acquiring images from the local gallery, that is, the "local gallery" in the interface 703, but also includes the options of available devices, such as "Tom's A-model mobile phone camera" 704 and "Tom's B-model tablet camera" 705. Among them, "Tom" is the user name of the user account, "A-model" and "B-model" are device models, and "mobile phone" and "tablet" are device types. "Tom's A-model mobile phone camera" can be used to trigger the remote camera of Tom's A-model mobile phone (such as mobile phone 220) to shoot images, and "Tom's B-model tablet camera" can be used to trigger the remote camera of Tom's B-model tablet (such as tablet 230) to shoot images.
以获取操作包括用户对图7B所示界面701中“图片”702的点击操作和用户对图7B所示界面706中“远程相机”707的点击操作为例，笔记本电脑210响应于用户对图7B所示界面706中“远程相机”707的点击操作，可以显示图7B所示的界面708。与界面703类似的，界面708中也包括可用设备的选项，如“汤姆的A型号手机的相机”704、“汤姆的B型号平板的相机”705。Taking the acquisition operation including the user's click operation on "Picture" 702 in interface 701 shown in FIG. 7B and the user's click operation on "Remote Camera" 707 in interface 706 shown in FIG. 7B as an example, the laptop computer 210 can display interface 708 shown in FIG. 7B in response to the user's click operation on "Remote Camera" 707 in interface 706 shown in FIG. 7B. Similar to interface 703, interface 708 also includes options for available devices, such as "Camera of Tom's Model A mobile phone" 704 and "Camera of Tom's Model B tablet" 705.
S504、笔记本电脑210接收用户对可用设备的选项中手机220的选项的选择操作。S504 , the notebook computer 210 receives the user's selection operation of the mobile phone 220 option among the available device options.
其中，手机220的选项也可以称为第一选项。选择操作可以是点击操作、长按操作、滑动操作等。下文主要以点击操作为例来说明。The option of the mobile phone 220 may also be referred to as the first option. The selection operation may be a click operation, a long press operation, a slide operation, etc. The following mainly takes the click operation as an example for explanation.
以手机220的选项是图7A所示界面703中的”汤姆的A型号手机的相机”704为例，则对手机220的选项的选择操作可以是对界面703中“汤姆的A型号手机的相机”704的点击操作。Taking the option of the mobile phone 220 as “Camera of Tom’s Model A Mobile Phone” 704 in the interface 703 shown in FIG. 7A as an example, the selection operation of the option of the mobile phone 220 may be a click operation on “Camera of Tom’s Model A Mobile Phone” 704 in the interface 703 .
需要说明的是，前述S503和S504中，以由用户手动选择手机220来说明，实际中，响应于获取操作，也可以由笔记本电脑210自动选择手机220。It should be noted that, in the above S503 and S504, the user manually selects the mobile phone 220 for illustration. In practice, The mobile phone 220 may also be automatically selected by the notebook computer 210 in response to the acquisition operation.
示例性的，笔记本电脑210可以基于可用设备的优先级来自动选择手机220。例如，按照拍摄灵活性，优先级由高至低依次为：手机、平板以及笔记本电脑，那么，在可用设备包括手机220和平板230时，笔记本电脑210可以自动选择手机220调用远程相机。又例如，作为被调用设备的次数越多，则优先级越高，作为被调用设备的次数越少，则优先级越低，且可用设备包括手机220和平板230，手机220的被调用次数多于平板230的被调用次数，则笔记本电脑210可以自动选择手机220调用远程相机。Exemplarily, the laptop 210 may automatically select the mobile phone 220 based on the priority of the available devices. For example, according to the shooting flexibility, the priority from high to low is: mobile phone, tablet and laptop computer. Then, when the available devices include the mobile phone 220 and the tablet 230, the laptop 210 may automatically select the mobile phone 220 to call the remote camera. For another example, the more times it is a called device, the higher the priority, and the fewer times it is a called device, the lower the priority. If the available devices include the mobile phone 220 and the tablet 230, and the number of times the mobile phone 220 is called is more than the number of times the tablet 230 is called, the laptop 210 may automatically select the mobile phone 220 to call the remote camera.
又示例性的，笔记本电脑210中可以在每次选择可用设备后，可记录选择的可用设备的信息，并且本次响应于获取操作，则基于记录的可用设备的信息自动选择前一次选择的可用设备。在一些场景中，响应于获取操作，笔记本电脑210确定出的可用设备中可能并不包括前一次选择的可用设备。如果可用设备中不包括前一次选择的可用设备，笔记本电脑210则可以基于优先级来自动选择，或者由用户手动来选择。这样，可以确保选择出可用设备。As another example, the laptop computer 210 may record the information of the selected available device each time after selecting an available device, and automatically select the previously selected available device based on the recorded available device information in response to the acquisition operation this time. In some scenarios, in response to the acquisition operation, the available devices determined by the laptop computer 210 may not include the previously selected available device. If the previously selected available device is not included in the available devices, the laptop computer 210 may automatically select based on the priority, or the user may select manually. In this way, it is ensured that an available device is selected.
S505、响应于选择操作，笔记本电脑210向手机220发送远程相机的调用请求。S505 , in response to the selection operation, the notebook computer 210 sends a remote camera calling request to the mobile phone 220 .
其中，调用请求(也可以称为第一请求)用于请求调用远程相机。The calling request (also referred to as the first request) is used to request to call the remote camera.
示例性的，响应于用户对图7A所示界面703中“汤姆的A型号手机的相机”704的选择操作，笔记本电脑可以向手机220发送远程相机的调用请求，以请求调用手机220的远程相机来实现拍摄。For example, in response to the user's selection operation of “Tom's Model A mobile phone camera” 704 in the interface 703 shown in FIG. 7A , the laptop computer may send a remote camera call request to the mobile phone 220 to request to call the remote camera of the mobile phone 220 to achieve shooting.
其中，调用请求中包括远程相机的能力信息(远程相机的能力信息可以指示调用请求所调用的能力，即本次调用的调用类型，因此远程相机的能力信息也可以称为请求类型)、笔记本电脑210的设备信息以及目标应用的应用标识。远程相机的能力信息，如标识“remote camera”、“远程相机”等，用于指示调用的能力为远程相机的能力。笔记本电脑210的设备信息，如媒体访问控制地址(Media Access ControlAddress，MAC)、设备序列号等可唯一指示笔记本电脑210的信息，用于指示请求调用的设备为笔记本电脑210；以及，目标应用的应用标识用于指示请求调用的应用为目标应用。上述设备信息和应用标识主要用于手机220在拍摄得到图像后，确定图像的接收对象，即接收对象为笔记本电脑210中的目标应用。Among them, the call request includes the capability information of the remote camera (the capability information of the remote camera can indicate the capability called by the call request, that is, the call type of this call, so the capability information of the remote camera can also be called the request type), the device information of the laptop computer 210, and the application identifier of the target application. The capability information of the remote camera, such as the identifiers "remote camera", "remote camera", etc., is used to indicate that the called capability is the capability of the remote camera. The device information of the laptop computer 210, such as the Media Access Control Address (MAC), the device serial number, etc., which can uniquely indicate the information of the laptop computer 210, is used to indicate that the device requesting the call is the laptop computer 210; and the application identifier of the target application is used to indicate that the application requesting the call is the target application. The above-mentioned device information and application identifier are mainly used for the mobile phone 220 to determine the receiving object of the image after capturing the image, that is, the receiving object is the target application in the laptop computer 210.
在一些实施例中，如果手机220满足拍摄图像的预设条件，响应于选择操作，笔记本电脑210还可以发出手机220正在拍摄的提示(也可以称为第一提示信息)。其中，如果满足预设条件，则表示手机220具备拍摄图像的条件。在一种具体的实现方式中，预设条件包括：第二设备处于开机状态、手机220的系统相机处于空闲状态等。空闲状态是指系统相机未在前台运行，例如，手机220当前未显示拍摄取景界面。In some embodiments, if the mobile phone 220 meets the preset conditions for taking images, in response to the selection operation, the laptop computer 210 may also issue a prompt (also referred to as first prompt information) that the mobile phone 220 is taking pictures. If the preset conditions are met, it means that the mobile phone 220 has the conditions for taking pictures. In a specific implementation, the preset conditions include: the second device is in a powered-on state, the system camera of the mobile phone 220 is in an idle state, etc. The idle state means that the system camera is not running in the foreground, for example, the mobile phone 220 currently does not display the shooting viewfinder interface.
示例性的，如果手机220的系统相机处于空闲状态、且手机220处于开机状态，那么，响应于用户对图7A所示界面703或者图7B所示界面708中的“汤姆的A型号手机的相机”704的选择操作，笔记本电脑210可以显示图7C所示的界面709，界面709中包括提示“汤姆的A型号手机的相机拍摄中”710，从而提示手机220正在拍摄。其中，该提示可以在显示预设时长之后则自动消失。或者，在显示该提示后，响应于用户取消显示该提示的取消操作后，笔记本电脑210才会取消显示该提示。例如，取消操作可以是用户对界面706中“取消”按钮的点击操作。如果未接收到取消操作，则笔记本电脑210会一直显示该提示。Exemplarily, if the system camera of the mobile phone 220 is in an idle state and the mobile phone 220 is in a powered-on state, then in response to the user's selection operation on the "Camera of Tom's Model A Mobile Phone" 704 in the interface 703 shown in FIG. 7A or the interface 708 shown in FIG. 7B , the laptop computer 210 may display the interface 709 shown in FIG. 7C , wherein the interface 709 includes a prompt "The camera of Tom's Model A Mobile Phone is shooting" 710, thereby prompting that the mobile phone 220 is shooting. Among them, the prompt may automatically disappear after being displayed for a preset period of time. Alternatively, after displaying the prompt, in response to the user's cancel operation of canceling the display of the prompt, the laptop computer 210 will cancel the display of the prompt. For example, the cancel operation may be a user clicking the "Cancel" button in the interface 706. If the cancel operation is not received, the laptop computer 210 will continue to display the prompt. The prompt is displayed.
反之，如果手机220不满足拍摄图像的预设条件，如手机220的前台正在显示拍摄取景界面或者手机220处于关机状态，笔记本电脑210也可以发出手机220无法拍摄的提示。这种情况下，响应于用户的预设操作(如返回操作、关闭提示的操作等)，笔记本电脑210可以继续显示可用设备的选项。这样，用户可以重新选择可用设备并调用。On the contrary, if the mobile phone 220 does not meet the preset conditions for shooting an image, such as the foreground of the mobile phone 220 is displaying the shooting view interface or the mobile phone 220 is turned off, the laptop computer 210 may also issue a prompt that the mobile phone 220 cannot shoot. In this case, in response to the user's preset operation (such as a return operation, an operation to close the prompt, etc.), the laptop computer 210 may continue to display the options of the available devices. In this way, the user can reselect the available device and call it.
应理解，响应于选择操作，笔记本电脑210则可以向手机220发送远程相机的调用请求，即此时笔记本电脑210可以与手机220交互。那么，笔记本电脑210可以通过与手机220交互，获取手机220的系统相机是否处于空闲状态、手机220是否处于开机状态的信息，以用于判断手机220是否满足拍摄图像的预设条件。It should be understood that in response to the selection operation, the laptop computer 210 can send a remote camera call request to the mobile phone 220, that is, at this time the laptop computer 210 can interact with the mobile phone 220. Then, the laptop computer 210 can obtain information about whether the system camera of the mobile phone 220 is in an idle state and whether the mobile phone 220 is in a powered-on state by interacting with the mobile phone 220, so as to determine whether the mobile phone 220 meets the preset conditions for capturing an image.
S506、响应于调用请求，手机220启动远程相机，以调用系统相机拍摄图像。S506 . In response to the calling request, the mobile phone 220 starts the remote camera to call the system camera to capture an image.
手机220在启动远程相机后，远程相机可以调用系统相机来拍摄图像。示例性的，手机220在接收到调用请求后，可以显示图8A所示的界面801，界面801为系统相机的拍摄取景界面(也可以称为第二界面)。手机220响应于用户对界面801中拍摄按钮802的点击操作，可以完成一张图片的拍摄。After the mobile phone 220 starts the remote camera, the remote camera can call the system camera to shoot an image. Exemplarily, after receiving the call request, the mobile phone 220 can display the interface 801 shown in FIG. 8A, and the interface 801 is the shooting and framing interface of the system camera (also referred to as the second interface). In response to the user clicking the shooting button 802 in the interface 801, the mobile phone 220 can complete the shooting of a picture.
以及，手机220在启动远程相机时，还会在远程相机中记录调用请求中的设备信息，用于指示笔记本电脑210调用远程相机，以便远程相机明确图像的接收对象。Furthermore, when the mobile phone 220 starts the remote camera, it will also record the device information in the calling request in the remote camera, which is used to instruct the notebook computer 210 to call the remote camera so that the remote camera can clearly know the recipient of the image.
应理解，系统相机仅仅具有拍摄的能力，而并不具备远程分发的业务功能。本申请实施例中，在系统相机之上部署远程相机。远程相机可以调用系统相机来拍摄。并且，远程相机还可以基于调用请求中的设备信息进行远程分发。从而实现将系统相机拍摄得到的图像分发给笔记本电脑210。It should be understood that the system camera only has the ability to shoot, but does not have the business function of remote distribution. In the embodiment of the present application, a remote camera is deployed on the system camera. The remote camera can call the system camera to shoot. In addition, the remote camera can also perform remote distribution based on the device information in the call request. In this way, the image captured by the system camera is distributed to the laptop computer 210.
在一些场景中，手机220接收到调用请求时，可能正在被使用，如正在使用手机220打电话、玩游戏等。此时，若直接调用远程相机，以进一步调用系统相机来拍摄，可能会影响手机220的使用。In some scenarios, when the mobile phone 220 receives the call request, it may be in use, such as using the mobile phone 220 to make a call, play games, etc. At this time, if the remote camera is directly called to further call the system camera to take pictures, the use of the mobile phone 220 may be affected.
基于此，在一些实施例中，手机220响应于调用请求，可以发出笔记本电脑210调用远程相机的提示(也可以称为第二提示信息)，并在接收到确认启动远程相机的确认事件后，才启动远程相机。这样，可以避免影响手机220的使用。Based on this, in some embodiments, the mobile phone 220 can send a prompt (also called second prompt information) to the laptop computer 210 to call the remote camera in response to the call request, and start the remote camera only after receiving a confirmation event to confirm starting the remote camera. In this way, the use of the mobile phone 220 can be avoided from being affected.
示例性的，手机220响应于调用请求，可以显示图8B所示的界面803，界面803中包括提示“笔记本电脑210想要开启远程相机，是否现在开启？”，并且界面803中还包括“是”和“否”两个选项。手机220响应于用户对界面803中“是”选项的选择操作，才会启动远程相机。即，确认事件包括用户对界面803中“是”选项的选择操作。例如，响应于用户对界面803中“是”选项的选择操作，手机220才会显示图8B所示的界面801。Exemplarily, in response to the call request, the mobile phone 220 may display the interface 803 shown in FIG. 8B , wherein the interface 803 includes a prompt “The laptop computer 210 wants to turn on the remote camera, do you want to turn it on now?”, and the interface 803 also includes two options “Yes” and “No”. The mobile phone 220 will start the remote camera only in response to the user’s selection operation of the “Yes” option in the interface 803. That is, the confirmation event includes the user’s selection operation of the “Yes” option in the interface 803. For example, in response to the user’s selection operation of the “Yes” option in the interface 803, the mobile phone 220 will display the interface 801 shown in FIG. 8B .
反之，手机220响应于用户对界面803中“否”选项的选择操作，可以恢复显示笔记本电脑210调用远程相机的提示之前的界面，如显示图8B所示的界面804，继续播放视频。On the contrary, in response to the user selecting the "No" option in the interface 803, the mobile phone 220 can restore the interface before the prompt of the laptop computer 210 calling the remote camera, such as the interface 804 shown in FIG. 8B, and continue to play the video.
又示例性的，手机220响应于调用请求，可以显示图8C所示的界面805，界面805中包括提示“笔记本电脑210想要开启远程相机，是否现在开启？”，并且界面805中还包括“是”和“否，稍后开启”两个选项。手机220响应于用户对界面805中“是”选项的选择操作，可以启动远程相机。即，确认事件包括用户对界面805中“是”选项的选择操作。例如，响应于用户对界面805中“是”选项的选择操作，手机220才会显示图8C所示的界面801。In another exemplary embodiment, in response to the call request, the mobile phone 220 may display the interface 805 shown in FIG8C , wherein the interface 805 includes a prompt “The laptop computer 210 wants to turn on the remote camera, do you want to turn it on now?”, and the interface 805 also includes two options “Yes” and “No, turn it on later”. In response to the user’s selection operation of the “Yes” option in the interface 805, the mobile phone 220 may start the remote camera. That is, the confirmation event includes the user’s selection operation of the “Yes” option in the interface 805. For example, in response to the user’s selection operation of the “Yes” option in the interface 805, the mobile phone 220 will display the interface 801 shown in FIG8C .
反之，手机220响应于用户对界面805中“否，稍后开启”选项的选择操作，可以显示图8C所示的界面806，界面806中包括多个延时时长，如1分钟、2分钟、3分钟等。用户可以从多个延时时长中选择目标时长，响应于用户对目标时长(如5分钟)的选择操作，手机220可以开始(如在9:00开始)计时，并在计时达到目标时长(如在9:05达到5分钟)后，如显示界面807后，启动远程相机。即，确认事件包括用户对界面806中目标时长的选择操作以及计时达到目标时长。例如，响应于用户对界面805中目标时长的选择操作且计时达到目标时长，手机220才会显示图8C所示的界面801。On the contrary, in response to the user's selection operation of the "No, open later" option in interface 805, the mobile phone 220 can display the interface 806 shown in FIG8C, and the interface 806 includes multiple delay durations, such as 1 minute, 2 minutes, 3 minutes, etc. The user can select a target duration from multiple delay durations. In response to the user's selection operation of the target duration (such as 5 minutes), the mobile phone 220 can start timing (such as at 9:00) and start the remote camera after the timing reaches the target duration (such as 5 minutes at 9:05), such as after displaying interface 807. That is, the confirmation event includes the user's selection operation of the target duration in interface 806 and the timing reaching the target duration. For example, in response to the user's selection operation of the target duration in interface 805 and the timing reaching the target duration, the mobile phone 220 will display the interface 801 shown in FIG8C.
另外，手机220响应于拒绝启动远程相机的拒绝事件，无需启动远程相机，并且向笔记本电脑210返回拒绝调用的反馈信息。示例性的，笔记本电脑210调用远程相机的提示中包括拒绝控件，如图8B所示界面803中“否”选项，拒绝事件可以是用户对拒接控件的点击、长按等操作。又示例性的，拒绝事件可以是手机220正在显示预设界面的事件。其中，预设界面可以是高权限应用的应用界面，如通话应用的通话界面。从而可以中断高权限应用的运行。预设界面可以是使用系统相机的界面，如拍照界面、视频通话界面等。从而可以避免中断系统相机的工作。In addition, in response to the rejection event of refusing to start the remote camera, the mobile phone 220 does not need to start the remote camera, and returns feedback information of the rejection of the call to the laptop computer 210. Exemplarily, the prompt for the laptop computer 210 to call the remote camera includes a rejection control, such as the "No" option in the interface 803 shown in FIG8B, and the rejection event can be a user's click, long press, and other operations on the rejection control. Another exemplary event may be an event that the mobile phone 220 is displaying a preset interface. Among them, the preset interface may be an application interface of a high-authority application, such as a call interface of a call application. Thereby, the operation of the high-authority application can be interrupted. The preset interface may be an interface for using the system camera, such as a photo taking interface, a video call interface, etc. Thereby, interrupting the operation of the system camera can be avoided.
S507、在完成拍摄后，手机220向笔记本电脑210传输图像。S507 , after completing the shooting, the mobile phone 220 transmits the image to the notebook computer 210 .
在手机220中，系统相机在拍摄得到图像后，手机220可以基于远程相机记录的笔记本电脑210的设备信息，向笔记本电脑210传输图像。In the mobile phone 220 , after the system camera captures an image, the mobile phone 220 can transmit the image to the laptop computer 210 based on the device information of the laptop computer 210 recorded by the remote camera.
在一些场景中，笔记本电脑210中的多个应用可能在先后在间隔较短的时间内调用不同设备的远程相机。例如，笔记本电脑210中的应用1调用手机220的远程相机，紧接着笔记本电脑210中的应用2调用平板230的远程相机。那么，手机220和平板230可能会几乎同时向笔记本电脑210传输拍摄得到的图像。此时，笔记本电脑210可能难以决策将来自手机220的图像和来自平板230的图像分别反馈给笔记本电脑210中的哪个应用。In some scenarios, multiple applications in the laptop computer 210 may call remote cameras of different devices in succession within a short time interval. For example, application 1 in the laptop computer 210 calls the remote camera of the mobile phone 220, and then application 2 in the laptop computer 210 calls the remote camera of the tablet 230. Then, the mobile phone 220 and the tablet 230 may transmit the captured images to the laptop computer 210 almost at the same time. At this time, the laptop computer 210 may find it difficult to decide which application in the laptop computer 210 to feed the images from the mobile phone 220 and the images from the tablet 230 respectively.
针对上述问题，在一些实施例中，在上述S505中，笔记本电脑210可以进一步在调用请求中携带目标应用的应用标识。那么，目标应用的应用标识也传输给手机220。相应的，在S506中，手机220启动远程相机时，不仅会在远程相机中记录调用请求中的设备信息，还会记录应用标识，用于指示笔记本电脑210中的目标应用调用远程相机，以进一步明确图像的接收对象。并且，在S507中，手机220在向笔记本电脑210传输图像时，还会传输远程相机中记录的目标应用的应用标识，以指示笔记本电脑210向目标应用反馈图像。如此，通过将图像的和应用标识一起反馈给笔记本电脑210的方式，可以使笔记本电脑210在接收到图像的同时，明确图像的接收应用，从而可以准确的向相应的应用反馈图像。In view of the above problem, in some embodiments, in the above S505, the laptop computer 210 can further carry the application identifier of the target application in the call request. Then, the application identifier of the target application is also transmitted to the mobile phone 220. Correspondingly, in S506, when the mobile phone 220 starts the remote camera, it will not only record the device information in the call request in the remote camera, but also record the application identifier to instruct the target application in the laptop computer 210 to call the remote camera to further clarify the receiving object of the image. And, in S507, when the mobile phone 220 transmits the image to the laptop computer 210, it will also transmit the application identifier of the target application recorded in the remote camera to instruct the laptop computer 210 to feedback the image to the target application. In this way, by feeding back the image and the application identifier to the laptop computer 210 together, the laptop computer 210 can clarify the receiving application of the image while receiving the image, so that the image can be accurately fed back to the corresponding application.
S508、笔记本电脑210显示手机220拍摄的图像。S508 : The notebook computer 210 displays the image captured by the mobile phone 220 .
示例性的，笔记本电脑210在接收到图片后，可以显示图9所示的界面901，界面901中包括图片902。以及，界面901中还包括提示“汤姆的A型号手机的相机拍摄中”903和“取消”按钮904。响应于用户对“取消”按钮904的点击操作，笔记本电脑210可以显示图9所示的界面905。界面905中不再显示提示“汤姆的A型号手机的相机拍摄中”903，用户可以继续编辑文档。Exemplarily, after receiving the picture, the laptop computer 210 may display the interface 901 shown in FIG. 9 , where the interface 901 includes the picture 902. Also, the interface 901 includes a prompt “The camera of Tom’s model A mobile phone is taking pictures” 903 and a “Cancel” button 904. In response to the user clicking the “Cancel” button 904, the laptop computer 210 may display the interface 905 shown in FIG. The prompt “The camera of Tom’s model A mobile phone is taking pictures” 903 is no longer displayed in the interface 905, and the user can continue to edit the document.
在一些场景中，可能会有多台设备先后在间隔较短的时间内调用同一设备的远程相机。示例性的，参见图10，在8点30分整，笔记本电脑210调用手机220的远程相机来拍摄，在8点30分至8点32分之间，平板230调用手机220的远程相机来拍摄。In some scenarios, multiple devices may call the remote camera of the same device in a short interval. For example, referring to FIG. 10 , at 8:30, the laptop 210 calls the remote camera of the mobile phone 220 to take a photo. Between 8:30 and 8:32, the tablet 230 uses the remote camera of the mobile phone 220 to take photos.
然而，在同一时刻，同一设备的远程相机只能被一台设备调用。也就是说，同一时刻，同一设备的远程相机只能被一台设备占用。继续参见图10，在笔记本电脑210调用手机220的远程相机后，在8点30分至8点32分的时间段内，手机220的远程相机一直处于被笔记本电脑210占用的工作状态。那么，在8点30分至8点32分之间，平板230将无法成功调用手机220的远程相机，而只能等到手机220的远程相机解除占用，平板230才能成功调用手机220的远程相机，这样会导致调用效率低下。However, at the same time, the remote camera of the same device can only be called by one device. In other words, at the same time, the remote camera of the same device can only be occupied by one device. Continuing to refer to FIG. 10, after the laptop 210 calls the remote camera of the mobile phone 220, during the time period from 8:30 to 8:32, the remote camera of the mobile phone 220 is always in a working state occupied by the laptop 210. Then, between 8:30 and 8:32, the tablet 230 will not be able to successfully call the remote camera of the mobile phone 220, and can only wait until the remote camera of the mobile phone 220 is unoccupied before the tablet 230 can successfully call the remote camera of the mobile phone 220, which will result in low calling efficiency.
针对上述图10类似的场景，参见图11，在一些实施例中，笔记本电脑210在向手机220发送调用请求之后，如S505之后，还包括：For a scenario similar to FIG. 10 , referring to FIG. 11 , in some embodiments, after the laptop computer 210 sends the call request to the mobile phone 220 , such as after S505 , the following further includes:
S1101、响应于启动远程相机，手机220向同账号设备(如笔记本电脑210)同步其远程相机的工作状态为被占用(也可以称为第二信息)。S1101. In response to starting the remote camera, the mobile phone 220 synchronizes the working status of its remote camera as occupied (also referred to as second information) to the device with the same account (such as the laptop computer 210).
示例性的，笔记本电脑210、手机220以及平板230中登录的用户账号均为荣耀账号a，那么，手机220响应于来自笔记本电脑210的调用请求，启动远程相机后，可以向笔记本电脑210和平板230同步其远程相机的工作状态为被占用。Exemplarily, the user accounts logged in to the laptop computer 210, the mobile phone 220 and the tablet 230 are all Honor account a. Then, in response to the call request from the laptop computer 210, after starting the remote camera, the mobile phone 220 can synchronize the working status of its remote camera to the laptop computer 210 and the tablet 230 as occupied.
在执行S1101之后，同账号设备(如笔记本电脑210)可以确定手机220中的远程相机正在被占用。After executing S1101 , the same account device (such as the laptop computer 210 ) may determine that the remote camera in the mobile phone 220 is being occupied.
以及，在本实施例中，在拍摄完成之后，如S507之后，还包括：And, in this embodiment, after the shooting is completed, such as after S507, the following steps are further included:
S1102、响应于完成拍摄，手机220向同账号设备(如笔记本电脑210)同步手机220的远程相机的工作状态为未被占用(也可以称为第三信息)。S1102 . In response to completing the shooting, the mobile phone 220 synchronizes the working state of the remote camera of the mobile phone 220 to the device with the same account (such as the laptop computer 210 ) as unoccupied (also referred to as the third information).
在执行S1102之后，同账号设备可以确定手机220中的远程相机未被占用。After executing S1102 , the device with the same account may determine that the remote camera in the mobile phone 220 is not occupied.
在本实施例中，可用设备为支持远程相机、且远程相机未被占用的在线设备。例如，手机220为支持远程相机的在线设备，但是其远程相机正在被占用，则不会将其确定为可用设备。那么，在S1101之后，S1102之前，如果同账号设备(如平板230)接收到图像的获取操作，则不会将支持远程相机、但远程相机被占用的在线设备(如手机220)确定为可用设备，后续则不会显示手机220的选项，或者，会显示处于不可操作状态(如置灰状态)的手机220的选项。从而无法调用手机220的远程相机，可以避免调用存在冲突。In this embodiment, the available device is an online device that supports a remote camera and whose remote camera is not occupied. For example, if the mobile phone 220 is an online device that supports a remote camera, but its remote camera is occupied, it will not be determined as an available device. Then, after S1101 and before S1102, if the same account device (such as the tablet 230) receives an image acquisition operation, the online device (such as the mobile phone 220) that supports a remote camera but whose remote camera is occupied will not be determined as an available device, and the option of the mobile phone 220 will not be displayed subsequently, or the option of the mobile phone 220 in an inoperable state (such as a grayed-out state) will be displayed. As a result, the remote camera of the mobile phone 220 cannot be called, and conflicts in calls can be avoided.
前文图5-图11主要以笔记本电脑210和手机220为执行主体说明了本申请实施例提供的图像拍摄方法，下面将结合笔记本电脑210和手机220的软件模块，进一步说明本申请实施例提供的图像拍摄方法。其中，关于笔记本电脑210和手机220中各个软件模块及其所属的层级，可以参见前文图4A和图4B的说明，此处不再赘述。The above-mentioned FIGS. 5 to 11 mainly illustrate the image capturing method provided by the embodiment of the present application by taking the laptop computer 210 and the mobile phone 220 as the execution subjects. The image capturing method provided by the embodiment of the present application will be further illustrated below in combination with the software modules of the laptop computer 210 and the mobile phone 220. Among them, the various software modules in the laptop computer 210 and the mobile phone 220 and the levels to which they belong can be referred to the above-mentioned description of FIGS. 4A and 4B, which will not be repeated here.
具体的，参见图12，在S501之前，还包括S1201-S1203：Specifically, referring to FIG. 12 , before S501, S1201 to S1203 are also included:
S1201、手机220的远程相机向手机220的设备管理服务注册远程相机的能力。S1201 . The remote camera of the mobile phone 220 registers the remote camera capability with the device management service of the mobile phone 220 .
其中，注册远程相机的能力，是指：远程相机将其具有的远程相机的能力(为同账号设备拍摄图像并回传的能力)告知设备管理服务。Registering the remote camera capability means that the remote camera informs the device management service of its remote camera capability (capability to capture images for devices with the same account and transmit them back).
在一些实施例中，在手机220首次开机时，手机220可在用户向导中提示启用远程相机，如果接收到用户开启远程相机的操作，则会触发远程相机向设备管理服务注册其能力。示例性的，在手机220首次开机时，手机220可以显示图13中的(a)所示的界面1301。界面1301是用户向导的一个界面，界面1301中包括语言选项，如“简体中文”、“繁体中文”、“英文”、“日文”等。手机220响应于用户对界面1301中“简体中文”的选择操作后，可以显示图13中的(b)所示的界面1302。界面1302是用户向导的另一个界面，界面1302中包括提示“开启远程相机后，则允许其他设备调用本设备拍摄图像，是否开启！”，用于提示启用远程相机。以及，界面1302中还包括“是”和“否”两个选项，开启远程相机的操作可以是对界面1302中“否”的选择操作。那么，响应于用户对界面1302中“否”的选择操作，则会触发手机220中的远程相机向设备管理服务注册其能力。In some embodiments, when the mobile phone 220 is powered on for the first time, the mobile phone 220 may prompt the user to enable the remote camera in the user wizard. If the user initiates an operation to enable the remote camera, the remote camera will be triggered to register its capabilities with the device management service. Exemplarily, when the mobile phone 220 is powered on for the first time, the mobile phone 220 may display the interface 1301 shown in (a) of FIG. 13 . The interface 1301 is an interface of the user wizard, and the interface 1301 includes language options, such as “Simplified Chinese”, “Traditional Chinese”, “English”, “Japanese”, etc. The mobile phone 220 responds to the user’s selection of “Simplified Chinese” in the interface 1301. After that, the interface 1302 shown in (b) of FIG. 13 may be displayed. The interface 1302 is another interface of the user guide. The interface 1302 includes a prompt "After turning on the remote camera, other devices are allowed to call this device to take images. Do you want to turn it on!", which is used to prompt the activation of the remote camera. In addition, the interface 1302 also includes two options "Yes" and "No". The operation of turning on the remote camera can be a selection operation of "No" in the interface 1302. Then, in response to the user's selection operation of "No" in the interface 1302, the remote camera in the mobile phone 220 will be triggered to register its capabilities with the device management service.
应注意，在图13的示例中，以用户在界面1301中选择语言后，则接着显示界面1302为例来说明。实际实施时，用户在界面1301中选择语言后，手机220也可以先显示其它引导界面，如先设置指纹、人脸、密码的引导界面或者数据导入的引导界面等，并在这些其它引导界面中完成设置后，手机220才跳转到界面1302。It should be noted that in the example of FIG13 , after the user selects a language in interface 1301, interface 1302 is displayed. In actual implementation, after the user selects a language in interface 1301, mobile phone 220 may first display other guide interfaces, such as a guide interface for setting fingerprint, face, password, or a guide interface for data import, and after completing the settings in these other guide interfaces, mobile phone 220 jumps to interface 1302.
在另一些实施例中，在手机220首次开机时，用户未执行启用远程相机的操作，但在后续使用手机220的过程中，接收到用户启用远程相机的操作，也可以触发远程相机向设备管理服务注册其能力。In other embodiments, when the mobile phone 220 is turned on for the first time, the user does not perform the operation of enabling the remote camera, but during the subsequent use of the mobile phone 220, receiving the user's operation of enabling the remote camera can also trigger the remote camera to register its capabilities with the device management service.
远程相机在注册其能力时，可以向设备管理服务发送远程相机的应用标识，如发送远程相机的APP包名，用于指示注册的应用为远程相机。以及，远程相机还可以向设备管理服务发送其能力的能力信息，用于指示注册的能力是远程相机的能力。When registering its capabilities, the remote camera may send the application identifier of the remote camera to the device management service, such as sending the APP package name of the remote camera, to indicate that the registered application is the remote camera. In addition, the remote camera may also send the capability information of its capabilities to the device management service to indicate that the registered capabilities are the capabilities of the remote camera.
S1202、手机220的设备管理服务记录远程相机及其注册的能力。S1202 . The device management service of the mobile phone 220 records the remote camera and its registered capabilities.
例如，设备管理服务记录远程相机的应用标识以及远程相机的能力的能力信息。For example, the device management service records the application identifier of the remote camera and capability information of the capabilities of the remote camera.
S1203、手机220的设备管理服务向手机220的远程相机反馈注册成功的消息。S1203 . The device management service of the mobile phone 220 feeds back a registration success message to the remote camera of the mobile phone 220 .
至此，则完成了远程相机的能力注册。At this point, the remote camera capability registration is completed.
在一些实施例中，在注册远程相机的能力后，如果用户不想将手机220继续用于为其他同账号设备拍摄图像，也可以在手机220中停用远程相机。响应于用户停用远程相机的操作，远程相机则会向设备管理服务请求注销其能力。设备管理服务在接收到来自远程相机的注销请求后，会删除远程相机的注册信息，如会删除远程相机的应用标识以及远程相机的能力的能力信息。In some embodiments, after registering the remote camera capability, if the user does not want to continue using the mobile phone 220 to capture images for other devices with the same account, the remote camera can also be disabled in the mobile phone 220. In response to the user's operation of disabling the remote camera, the remote camera will request the device management service to deregister its capability. After receiving the deregistration request from the remote camera, the device management service will delete the registration information of the remote camera, such as deleting the application identifier of the remote camera and the capability information of the remote camera.
继续参见图12，在笔记本电脑210中，S501进一步包括以下S5011-S5013：Continuing to refer to FIG. 12 , in the notebook computer 210 , S501 further includes the following S5011 - S5013:
S5011、手机220的设备管理服务通过互联网向同账号设备(如笔记本电脑210)的设备管理服务同步远程相机能力。S5011. The device management service of the mobile phone 220 synchronizes the remote camera capability with the device management service of the same account device (such as the laptop computer 210) via the Internet.
手机220和笔记本电脑210登录相同的用户账号，则两者的设备管理服务可以通过互联网(即云端)同步远程相机的能力的支持情况。当然，如果还有其他同账号设备，则手机220的设备管理服务同样可以向其他同账号设备的设备管理服务同步其远程相机的能力。If the mobile phone 220 and the laptop computer 210 log in to the same user account, the device management services of the two can synchronize the support status of the remote camera capability through the Internet (i.e., the cloud). Of course, if there are other devices with the same account, the device management service of the mobile phone 220 can also synchronize its remote camera capability with the device management services of other devices with the same account.
在同步远程相机的能力(即同步第一信息)时，手机220的设备管理服务可以向笔记本电脑210的设备管理服务同步手机220的设备信息(如手机220的名称)以及远程相机能力的能力信息，以指示手机220支持远程相机。When synchronizing the capabilities of the remote camera (i.e., synchronizing the first information), the device management service of the mobile phone 220 can synchronize the device information of the mobile phone 220 (such as the name of the mobile phone 220) and the capability information of the remote camera capabilities to the device management service of the laptop computer 210 to indicate that the mobile phone 220 supports the remote camera.
应理解，如果手机220中的远程相机向设备管理服务注销了远程相机的能力，那么，手机220的设备管理服务也会向笔记本电脑210的设备管理服务同步注销远程相机的能力，相应的，笔记本电脑210的设备管理服务会删除掉手机220支持远程相机的信息，如删除手机220的设备信息以及远程相机能力的能力信息。It should be understood that if the remote camera in the mobile phone 220 unregisters the remote camera capability to the device management service, then the device management service of the mobile phone 220 will also synchronously unregister the remote camera capability to the device management service of the laptop computer 210. Correspondingly, the device management service of the laptop computer 210 will delete the information that the mobile phone 220 supports the remote camera, such as deleting the device information of the mobile phone 220 and the capability information of the remote camera capability.
S5012、笔记本电脑210的通信服务发现(手机220为)近场通信范围内的在线设备。S5012. The communication service of the notebook computer 210 discovers an online device (the mobile phone 220) within the near field communication range.
笔记本电脑210的通信服务(如Magic Link)可以定期扫描并发现笔记本电脑210的近场通信范围内的设备。The communication service of the laptop 210 (such as Magic Link) can periodically scan and discover the Devices within NFC range.
在笔记本电脑210发现手机220之后，笔记本电脑210和手机220可以通过通信服务(如Magic Link)传输数据，如传输调用请求、图像等。After the laptop computer 210 discovers the mobile phone 220, the laptop computer 210 and the mobile phone 220 can transmit data, such as transmitting call requests, images, etc., through a communication service (such as Magic Link).
S5013、笔记本电脑210的通信服务向笔记本电脑210的设备管理服务更新(手机220为)在线设备。S5013. The communication service of the notebook computer 210 updates the online device (the mobile phone 220) to the device management service of the notebook computer 210.
这样，笔记本电脑210的设备管理服务可以确定手机220为在线设备。In this way, the device management service of the laptop computer 210 can determine that the mobile phone 220 is an online device.
在一些实施例中，在笔记本电脑210中，目标应用只有在接入接续服务的情况下，接续服务才能为其提供查询可用设备、跨设备传输调用请求以及图像等数据的服务。In some embodiments, in the laptop computer 210, the connection service can provide the target application with services such as querying available devices, transmitting call requests and data such as images across devices only when the target application is connected to the connection service.
基于此，继续参见图12，在笔记本电脑210中，还包括下述S1204-S1208。应注意，S1204-S1208，与前述S1201-S5013之间并没有严格的先后顺序限制。实际中，只要目标应用冷启动，则会在笔记本电脑210中执行下述S1204-S1208。Based on this, referring to FIG. 12 , the laptop computer 210 further includes the following S1204-S1208. It should be noted that there is no strict order restriction between S1204-S1208 and the aforementioned S1201-S5013. In practice, as long as the target application is cold started, the following S1204-S1208 will be executed in the laptop computer 210.
S1204、响应于笔记本电脑210的目标应用冷启动，向笔记本电脑210的接续服务发送接入请求。S1204 : In response to the target application of the notebook computer 210 being cold started, sending an access request to the connection service of the notebook computer 210 .
其中，接入请求用于请求接入接续服务。接入请求中包括目标应用的应用标识，用于指示目标应用想要接入接续服务。The access request is used to request access to the continuation service. The access request includes an application identifier of the target application, which is used to indicate that the target application wants to access the continuation service.
在笔记本电脑210中，目标应用在冷启动的过程中，可以向接续服务发送接入请求。其中，冷启动是指：在目标应用启动前，笔记本电脑210的系统中没有目标应用的进程。在冷启动的过程中，目标应用向接续服务发送接入请求，则可以重新建立目标应用的进程和接续服务的进程之间的联系，便于后续实现调用远程相机。In the notebook computer 210, the target application can send an access request to the connection service during the cold start process. The cold start means that before the target application is started, there is no process of the target application in the system of the notebook computer 210. During the cold start process, the target application sends an access request to the connection service, and the connection between the process of the target application and the process of the connection service can be re-established, which is convenient for the subsequent call of the remote camera.
S1205、笔记本电脑210的接续服务向笔记本电脑210的应用鉴权服务发送鉴权请求。S1205 . The connection service of the notebook computer 210 sends an authentication request to the application authentication service of the notebook computer 210 .
其中，鉴权请求用于请求对应用鉴权。鉴权请求中包括目标应用的应用标识，用于指示对目标应用进行鉴权。The authentication request is used to request authentication of the application. The authentication request includes an application identifier of the target application, which is used to instruct authentication of the target application.
S1206、笔记本电脑210的应用鉴权服务对目标应用鉴权。S1206. The application authentication service of the notebook computer 210 authenticates the target application.
在目标应用接入接续服务前，先对目标应用的合法性进行校验，如校验目标应用的身份和权限。Before the target application accesses the subsequent service, the legitimacy of the target application is first verified, such as verifying the identity and permissions of the target application.
S1207、笔记本电脑210的应用鉴权服务向笔记本电脑210的接续服务反馈鉴权成功的消息。S1207 . The application authentication service of the notebook computer 210 feeds back a message of successful authentication to the connection service of the notebook computer 210 .
其中，鉴权成功的消息中携带有鉴权成功的目标应用的应用标识，用于指示目标应用鉴权成功。The authentication success message carries the application identifier of the target application that has been successfully authenticated, which is used to indicate that the authentication of the target application has been successful.
S1208、笔记本电脑210的接续服务向笔记本电脑210的目标应用返回接入成功的消息。S1208 . The connection service of the notebook computer 210 returns a message of successful access to the target application of the notebook computer 210 .
在确认目标应用合法的情况下，接续服务才向目标应用返回接入成功的消息，即允许目标应用接入接续服务。从而避免为非法应用提供查询可用设备、跨设备传输调用请求以及图像等数据的服务。Only when the target application is confirmed to be legitimate, the connection service returns a successful access message to the target application, that is, the target application is allowed to access the connection service. This avoids providing services such as querying available devices, cross-device transmission of call requests, and image data to illegal applications.
继续参见图12，在笔记本电脑210中，用户可以在目标应用中执行获取图像的获取操作，相应的，S502具体为S5021：Continuing to refer to FIG. 12 , in the notebook computer 210 , the user can perform an operation of acquiring an image in the target application. Accordingly, S502 is specifically S5021:
S5021、笔记本电脑210的目标应用接收获取图像的获取操作。S5021. The target application of the notebook computer 210 receives an acquisition operation of acquiring an image.
示例性的，获取操作为用户对图7A所示界面701中“图片”702的点击操作。Exemplarily, the acquisition operation is a user clicking operation on “Picture” 702 in the interface 701 shown in FIG. 7A .
继续参见图12，在笔记本电脑210中，S503进一步包括S5031-S5036：Continuing to refer to FIG. 12 , in the notebook computer 210 , S503 further includes S5031 - S5036:
S5031、响应于获取操作，笔记本电脑210的目标应用向笔记本电脑210的接续服务请求查询可用设备。S5031 . In response to the acquisition operation, the target application of the notebook computer 210 queries the connection service of the notebook computer 210 for available devices.
其中，可用设备是指支持远程相机的在线设备。在一些实施例中，同账号设备的设备管理服务之间，不仅会同步远程相机的能力，还会同步远程相机被占用的情况，如正在被占用或未被占用，具体可参见前文图10的相关说明。在本实施例中，可用设备是指支持远程相机、且远程相机未被占用的在线设备。Among them, the available device refers to an online device that supports the remote camera. In some embodiments, the device management services of the same account device will not only synchronize the capabilities of the remote camera, but also synchronize the occupancy of the remote camera, such as being occupied or not occupied. For details, please refer to the relevant description of Figure 10 above. In this embodiment, the available device refers to an online device that supports the remote camera and the remote camera is not occupied.
由于笔记本电脑210中的目标应用已经获得了接续服务的调用信息，则该目标应用可以调用接续服务来查询可用设备。Since the target application in the notebook computer 210 has obtained the calling information of the connection service, the target application can call the connection service to query the available devices.
S5032、笔记本电脑210的接续服务向笔记本电脑210的设备管理服务查询可用设备，可用设备包括手机220。S5032 , the connection service of the notebook computer 210 queries the device management service of the notebook computer 210 for available devices, where the available devices include the mobile phone 220 .
S5033、笔记本电脑210的设备管理服务确定可用设备。S5033. The device management service of the notebook computer 210 determines available devices.
笔记本电脑210的设备管理服务中记录有支持远程相机的设备，以及记录有在线设备。因此，笔记本电脑210的设备管理服务可以将既是支持远程相机的设备，也是在线设备的设备确定为可用设备。The device management service of the notebook computer 210 records the devices supporting the remote camera and the online devices. Therefore, the device management service of the notebook computer 210 can determine the devices that are both the devices supporting the remote camera and the online devices as available devices.
示例性的，支持远程相机的设备包括手机220以及平板230，在线设备为手机220，则可以确定可用设备为手机220。Exemplarily, the devices supporting the remote camera include a mobile phone 220 and a tablet 230 , and if the online device is the mobile phone 220 , then it can be determined that the available device is the mobile phone 220 .
S5034、笔记本电脑210的设备管理服务向笔记本电脑210的接续服务返回可用设备的设备信息。S5034. The device management service of the notebook computer 210 returns the device information of the available devices to the connection service of the notebook computer 210.
S5035、笔记本电脑210的接续服务向笔记本电脑210的目标应用返回可用设备的设备信息。S5035 . The connection service of the notebook computer 210 returns device information of available devices to the target application of the notebook computer 210 .
这样，目标应用就获得了可以调用可用设备的设备信息。In this way, the target application obtains the device information that can be used to call the available devices.
通常情况下，可用设备的设备信息包括可用设备的MAC地址、设备序列号等可以唯一标识各个可用设备的信息。Typically, the device information of an available device includes information such as a MAC address of the available device and a device serial number that can uniquely identify each available device.
而在一些实施例中，为了避免隐私泄露，可用设备的设备信息可以用可用设备的临时身份(identification，ID)来表示。In some embodiments, in order to avoid privacy leakage, the device information of the available device may be represented by a temporary identity (identification, ID) of the available device.
示例性的，手机220不仅提供有远程相机的能力，还提供有其他远程能力(如远程翻译的能力、远程搜索的能力等)可供调用，那么，笔记本电脑210中的一个或多个应用在调用这些能力时，就会发现手机220同时安装有相机应用、翻译应用、搜索应用，造成隐私泄露。例如，如果该一个或多个应用来自同一开发商，则该开发商通过大数据分析，可以构建手机220的画像。For example, the mobile phone 220 not only provides the remote camera capability, but also provides other remote capabilities (such as remote translation capability, remote search capability, etc.) for invocation. Then, when one or more applications in the laptop 210 invoke these capabilities, they will find that the mobile phone 220 has installed a camera application, a translation application, and a search application at the same time, causing privacy leakage. For example, if the one or more applications are from the same developer, the developer can build a portrait of the mobile phone 220 through big data analysis.
具体的，在本实施例中，笔记本电脑210在发现(手机220为)在线设备(如S5012)后，笔记本电脑210的通信服务和各个在线设备(如手机220)的通信服务之间协商出各个设备(如笔记本电脑210和手机220)的临时ID。例如，协商出笔记本电脑210的临时ID为111，手机220的临时ID为222。并且，笔记本电脑210的通信服务可以将各个在线设备的临时ID也发送给笔记本电脑210的设备管理服务。然后，在向目标应用返回可用设备的设备信息(如S5034和S5035)时，可以返回可用设备的临时ID。这样，可以避免因将可用设备的MAC地址、设备序列号等固定不变的标识信息发送给目标应用，而导致隐私泄露。Specifically, in this embodiment, after the laptop computer 210 discovers that (the mobile phone 220 is) an online device (such as S5012), the communication service of the laptop computer 210 and the communication service of each online device (such as the mobile phone 220) negotiate the temporary ID of each device (such as the laptop computer 210 and the mobile phone 220). For example, the negotiated temporary ID of the laptop computer 210 is 111, and the temporary ID of the mobile phone 220 is 222. In addition, the communication service of the laptop computer 210 can also send the temporary ID of each online device to the device management service of the laptop computer 210. Then, when returning the device information of the available device to the target application (such as S5034 and S5035), the temporary ID of the available device can be returned.
