本申请实施例涉及电子技术领域，尤其涉及一种拍摄方法及设备。The embodiments of the present application relate to the field of electronic technology, and in particular, to a photographing method and device.
背景技术Background technique
随着电子技术的发展，电子设备上集成的摄像头越来越多。该多个摄像头可以包括多个焦段的摄像头，例如可以包括短焦广角摄像头、中焦摄像头和长焦摄像头。不同焦段的摄像头可以对应不同的取景范围和变焦倍率，从而可以丰富电子设备的拍摄场景。With the development of electronic technology, more and more cameras are integrated on electronic equipment. The plurality of cameras may include cameras with multiple focal lengths, for example, may include a short-focus wide-angle camera, a medium-focus camera, and a telephoto camera. Cameras with different focal lengths can correspond to different viewing ranges and zoom ratios, thereby enriching shooting scenes of electronic devices.
在用户切换变焦倍率时，电子设备用于拍摄的摄像头也可能随之切换。例如，在切换到大变焦倍率时，电子设备可以由广角摄像头或中焦摄像头切换到长焦摄像头，从而显示长焦摄像头的预览画面，采用长焦摄像头进行拍摄。When the user switches the zoom ratio, the camera used by the electronic device for shooting may also switch accordingly. For example, when switching to a large zoom ratio, the electronic device can switch from a wide-angle camera or a medium-focus camera to a telephoto camera, thereby displaying a preview image of the telephoto camera, and using the telephoto camera for shooting.
在由广角摄像头或中焦摄像头切换到长焦摄像头后，取景范围变小，待拍摄的目标对象容易跑出长焦摄像头的预览画面。即，电子设备容易丢失待拍摄的目标对象。在采用长焦摄像头进行预览的情况下，用户通常花费较长时间也难以找到目标对象。After switching from a wide-angle camera or a medium-focus camera to a telephoto camera, the viewfinder range becomes smaller, and the target object to be photographed tends to run out of the preview screen of the telephoto camera. That is, the electronic device easily loses the target object to be photographed. In the case of previewing with a telephoto camera, it usually takes a long time for the user to find the target object.
发明内容Contents of the invention
本申请实施例提供一种拍摄方法及设备，能够根据目标对象引导用户移动电子设备，以便电子设备可以采用长焦摄像头快速锁定目标对象，节省用户寻找目标对象的时间，提高用户使用体验。Embodiments of the present application provide a shooting method and device, which can guide a user to move an electronic device according to a target object, so that the electronic device can quickly lock the target object with a telephoto camera, save the user time for searching for the target object, and improve user experience.
为达到上述目的，本申请实施例采用如下技术方案：In order to achieve the above purpose, the embodiment of the present application adopts the following technical solutions:
一方面，本申请实施例提供了一种拍摄方法，包括：电子设备启动相机。而后，电子设备采用第一摄像头和第二摄像头分别采集第一预览图像和第二预览图像。其中，第二摄像头为长焦摄像头，第一摄像头的取景范围大于第二摄像头的取景范围。电子设备显示第一预览界面。该第一预览界面包括第一取景框、第二取景框和第三取景框。第一取景框用于显示第一预览图像。第二取景框内的图像为第一预览图像上的一部分；且第二取景框中的内容为第二摄像头待拍摄的目标对象。第三取景框用于显示第二预览图像。电子设备显示第一提示信息，第一提示信息用于引导用户移动电子设备，以使得电子设备移动后第二摄像头可锁定目标对象。On the one hand, an embodiment of the present application provides a photographing method, including: starting a camera by an electronic device. Then, the electronic device collects the first preview image and the second preview image respectively by using the first camera and the second camera. Wherein, the second camera is a telephoto camera, and the viewing range of the first camera is larger than that of the second camera. The electronic device displays the first preview interface. The first preview interface includes a first viewing frame, a second viewing frame and a third viewing frame. The first viewing frame is used to display the first preview image. The image in the second viewing frame is a part of the first preview image; and the content in the second viewing frame is the target object to be photographed by the second camera. The third viewing frame is used to display the second preview image. The electronic device displays first prompt information, and the first prompt information is used to guide the user to move the electronic device, so that the second camera can lock the target object after the electronic device moves.
这样，在电子设备由广角摄像头或中焦摄像头等第一摄像头，切换到长焦摄像头即第二摄像头后，电子设备可以通过提示信息指引用户移动电子设备。以便，在电子设备移动后，长焦摄像头能够快速锁定目标对象。进而，电子设备可以采用长焦摄像头拍摄目标对象的图像。In this way, after the electronic device switches from a first camera such as a wide-angle camera or a medium-focus camera to a second camera that is a telephoto camera, the electronic device can guide the user to move the electronic device through prompt information. So that, after the electronic device moves, the telephoto camera can quickly lock the target object. Furthermore, the electronic device may use a telephoto camera to capture an image of the target object.
在一种可能的设计中，在电子设备显示第一预览界面之后，该方法还包括：电子设备检测到用户针对第二取景框的拖动操作。电子设备响应于拖动操作，在第一预览图像上移动第二取景框，目标对象随着第二取景框位置的变化而变化。In a possible design, after the electronic device displays the first preview interface, the method further includes: the electronic device detects a user's drag operation on the second viewfinder frame.

具体实施方式Detailed ways
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请实施例的描述中，“多个”是指两个或多于两个。The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Among them, in the description of the embodiments of this application, unless otherwise specified, "/" means or means, for example, A/B can mean A or B; "and/or" in this article is only a description of associated objects The association relationship of indicates that there may be three kinds of relationships, for example, A and/or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. In addition, in the description of the embodiments of the present application, "plurality" refers to two or more than two.
长焦摄像头的取景范围小，长焦摄像头拍摄的图像上物体的尺寸较大，可以适用于拍摄远处的物体，特写场景，物体细节，或专门拍摄某个较小的物体。广角摄像头和中焦摄像头的取景范围较大，可以拍摄较大范围内的物体和画面。The viewfinder range of the telephoto camera is small, and the size of the object on the image taken by the telephoto camera is relatively large, which can be suitable for shooting distant objects, close-up scenes, object details, or specially shooting a certain smaller object. The wide-angle camera and the medium-focus camera have a larger viewfinder range, and can capture objects and pictures in a larger range.
在由广角摄像头或中焦摄像头等其他摄像头切换到长焦摄像头进行拍摄时，电子设备容易丢失待拍摄的目标对象。即，电子设备通过长焦摄像头难以锁定目标对象。用户无法在长焦摄像头的预览界面上看到目标对象。现有技术中，在丢失目标对象后，用户并不知道目标对象的具体位置，因而通常盲目地向四周试探性搜索，以期望寻找到目标对象。并且，由于长焦摄像头的取景范围(或称可拍摄的视角范围)小，且目标对象通常距离用户较远，因而用户在搜寻时也比较容易错过目标对象。因此，用户往往花费较多的时间和精力，也难以搜寻到目标对象。When switching from other cameras such as a wide-angle camera or a medium-focus camera to a telephoto camera for shooting, the electronic device is likely to lose the target object to be photographed. That is, it is difficult for an electronic device to lock a target object through a telephoto camera. Users cannot see the target object on the preview interface of the telephoto camera. In the prior art, after the target object is lost, the user does not know the specific location of the target object, and thus usually tentatively searches around blindly, hoping to find the target object. Moreover, since the telephoto camera has a small viewing range (or a field of view that can be photographed), and the target object is usually far away from the user, it is easier for the user to miss the target object when searching. Therefore, the user often spends more time and energy, and it is also difficult to search for the target object.
本申请实施例提供了一种拍摄方法，可以应用于电子设备。例如，该电子设备具体可以是手机、平板电脑、可穿戴设备、车载设备、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、笔记本电脑、超级移动个人计算机(ultra-mobilepersonal computer，UMPC)、上网本、个人数字助理(personal digital assistant，PDA)或专门的照相机(例如单反相机、卡片式相机)等，本申请实施例对电子设备的具体类型不作任何限制。An embodiment of the present application provides a photographing method, which can be applied to an electronic device. For example, the electronic device may specifically be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (augmented reality, AR)/virtual reality (virtual reality, VR) device, a notebook computer, an ultra-mobile personal computer (ultra-mobilepersonal computer, UMPC), netbook, personal digital assistant (personal digital assistant, PDA) or specialized camera (such as single-lens reflex camera, card camera), etc., the embodiment of the present application does not make any limitation on the specific type of electronic equipment.
在本申请的实施例中，在拍摄场景下，用户可以指定目标对象。在电子设备由广角摄像头或中焦摄像头等其他摄像头切换到长焦摄像头后，电子设备可以根据用户指定的目标对象，指引用户移动电子设备。用户可以根据该指引移动电子设备，从而使得移动电子设备后长焦摄像头能够快速锁定目标对象。进而，电子设备可以采用长焦摄像头拍摄目标对象的图像。In the embodiment of the present application, in the shooting scene, the user can specify the target object. After the electronic device switches from a wide-angle camera or a medium-focus camera and other cameras to a telephoto camera, the electronic device can guide the user to move the electronic device according to the target object specified by the user. The user can move the electronic device according to the guidance, so that the telephoto camera behind the mobile electronic device can quickly lock the target object. Furthermore, the electronic device may use a telephoto camera to capture an image of the target object.

As another example, when the screen is bright and the desktop is displayed, or in the case of a black screen as shown in Figure 4C, if the mobile phone detects that the user has drawn a preset track 2 (such as "CF" track) operation, start the camera and enter the telephoto assist mode.
以上描述的进入长焦辅助模式的方式仅为示例性说明，手机还可以通过其他方式进入长焦辅助模式，本申请实施例对该具体方式不予限定。The method for entering the telephoto assist mode described above is only for illustration, and the mobile phone may also enter the telephoto assist mode through other methods, which are not limited in the embodiment of the present application.
在进入长焦辅助模式后，手机开启辅助摄像头和长焦摄像头。手机可以显示长焦辅助预览界面。如图5A或图5B所示，长焦辅助预览界面501可以包括辅助取景框502和目标取景框503。在一些实施例中，如图5C或图5D所示，长焦辅助预览界面501还可以包括实时取景框504。After entering the telephoto assist mode, the mobile phone turns on the auxiliary camera and the telephoto camera. The mobile phone can display the telephoto auxiliary preview interface. As shown in FIG. 5A or FIG. 5B , the telephoto
其中，辅助取景框502可以用于显示辅助摄像头采集的预览图像，该预览图像也称辅助预览图像。该辅助摄像头可以是默认的摄像头，也可以是用户指定的摄像头。该辅助摄像头可以为取景范围大于长焦摄像头的广角摄像头或中焦摄像头等。在一些实施例中，辅助取景框502可以布满整个显示区域，即手机可以全屏显示辅助预览图像。Wherein, the
示例性的，辅助摄像头为广角摄像头。图5C所示的辅助取景框502中显示广角摄像头采集到的辅助预览图像。手机在检测到用户点击控件505的操作后，可以将辅助摄像头切换为中焦摄像头，辅助取景框502中显示中焦摄像头采集到的辅助预览图像。Exemplarily, the auxiliary camera is a wide-angle camera. The auxiliary preview image captured by the wide-angle camera is displayed in the
辅助取景框502中辅助预览图像的变焦倍率可以根据用户的指示而相应地变化。示例性的，参见图5E，手机检测到用户拖动变焦标尺506的操作后，可以调整辅助取景框502中辅助预览图像的变焦倍率。The zoom ratio of the auxiliary preview image in the
目标取景框503可以用于显示用户在辅助预览图像上指定的，长焦摄像头待拍摄的目标对象。即目标取景框503中的内容为用户指定的目标对象。在一些实施例中，目标取景框503附近可以显示有提示信息，或者手机可以播放语音信息，以提示用户该取景框用于框选目标对象。The
目标取景框503中的图像是辅助预览图像上选取的一部分。目标取景框503中显示的图像大小与辅助预览图像上的图像大小相匹配。在用户指定目标对象后，当辅助取景框502中的辅助预览图像发生变化时，目标取景框503随着辅助预览图像上目标对象位置的移动而移动。当辅助取景框502中图像的变焦倍率变化时，辅助取景框502中显示的图像大小也相应变化，目标取景框503中显示的图像大小也相应变化。The image in the
示例性的，与图5C相比，图5E对应的辅助预览图像的变焦倍率较大，目标取景框503中目标对象的图像尺寸也较大。Exemplarily, compared with FIG. 5C , the zoom magnification of the auxiliary preview image corresponding to FIG. 5E is larger, and the image size of the target object in the
在一些实施例中，在进入长焦辅助预览模式后，目标取景框503可以默认位于辅助预览图像的中心区域，或者默认位于用户上一次指定的位置，或者默认框选辅助预览图像上的人物、建筑或其他某个物体。用户可以拖动目标取景框503，以使得长焦摄像头待拍摄的目标对象位于目标取景框503内，从而选定长焦摄像头待拍摄的目标对象。并且，用户还可以通过拖动目标取景框503，改变目标取景框503的位置，更改目标取景框503中的内容，从而更改长焦摄像头待拍摄的目标对象。In some embodiments, after entering the telephoto auxiliary preview mode, the
在另一些实施例中，在进入长焦辅助预览模式后，目标取景框503处于默认位置。目标取景框503中的内容，可能并不是用户想要通过长焦摄像头拍摄的目标对象，用户尚未指定目标对象。手机检测到用户拖动目标取景框503的操作后，确定用户指定了目标对象，目标取景框503中的内容即为用户指定的目标对象。In some other embodiments, after entering the telephoto auxiliary preview mode, the
在目标取景框503移动的过程中，实时取景框504还可以自动进行移动，以避让目标取景框503，从而避免实时取景框504和目标取景框503发生重叠，方便用户直观、清楚地看到实时取景框504和目标取景框503中的内容。During the moving process of the
示例性的，在图5C所示的情况下，用户拖动目标取景框503后，手机显示的长焦辅助预览界面可以如图5F所示。Exemplarily, in the situation shown in FIG. 5C , after the user drags the
在一些实施例中，目标取景框503的大小是固定的。在另一些实施例中，目标取景框503的大小可以发生变化。实时取景框504内显示的图像的变焦倍率可以与目标取景框503的大小负相关。即，目标取景框503越大，则实时取景框504内图像的变焦倍率越小；目标取景框503越小，则实时取景框504内图像的变焦倍率越大。用户可以通过调整目标取景框503的大小，来实时取景框504内图像的变焦倍率。In some embodiments, the size of the
由于实时取景框504中显示的是长焦摄像头实时采集到的预览图像，因而在一些实施例中，长焦摄像头实时采集到的预览图像的变焦倍率也可以与目标取景框503的大小负相关。Since the
示例性的，参见图5G，目标取景框503上显示有数字标记507和缩放标记508。当用户按住缩放标记508拖动目标取景框503的边线时，目标取景框503的大小相应变化。数字标记507中的数字与变化后的目标取景框503的大小相对应。当用户未按住缩放标记508而直接拖动目标取景框503的边线时，目标取景框503的位置发生移动，目标取景框503的大小不变。Exemplarily, referring to FIG. 5G , a
再示例性的，目标取景框503上显示有缩放标记508，当用户点击目标取景框后第一次拖动目标取景框503的边线时，目标取景框503的大小相应变化。当用户点击目标取景框后第n(n为大于1的整数)次拖动目标取景框503的边线时，或者当用户未点击缩放标记508而直接拖动目标取景框503的边线时，目标取景框503的位置发生移动，目标取景框503的大小不变。As another example, a
当实时取景框504内图像的变焦倍率变化时，目标取景框503的大小也随之变化。例如，当用户更改图5G所示的数字标记507中的数字时，或者当用户在实时取景框504里进行捏合操作或与捏合相反的操作时，实时取景框504内图像的变焦倍率发生变化，目标取景框503的大小也随之变化。When the zoom ratio of the image in the
实时取景框504中可以显示长焦摄像头实时采集的预览图像。在一些实施例中，实时取景框504附近可以显示有提示信息，或者手机可以播放语音信息，以提示用户该取景框内显示的图像为长焦摄像头采集到的图像。A preview image captured by the telephoto camera in real time may be displayed in the
在一些实施例中，实时取景框504中显示的图像的尺寸可以与长焦摄像头默认的变焦倍率(例如为5)相对应。在另一些实施例中，实时取景框504内显示的图像的变焦倍率与目标取景框503的大小相对应。当目标取景框503的大小变化时，实时取景框504内显示的图像的变焦倍率也相应变化。示例性的，与图5C相比，图5E中实时取景框504内显示的图像的变焦倍率增大为4，实时取景框504中显示的预览图像的尺寸较大，与变焦倍率4相匹配。在另一些实施例中，实时取景框504中显示的图像的尺寸，可以与辅助预览图像当前的变焦倍率相对应。In some embodiments, the size of the image displayed in the
在一些实施例中，实时取景框504的大小固定。在另一些实施例中，用户也可以修改实时取景框504的大小。In some embodiments, the size of the
在一些实施例中，实时取景框504的尺寸比例(即实时取景框504相邻两边的比例)以及目标取景框503的尺寸比例(即目标取景框503相邻两边的比例)，可以与长焦摄像头感光传感器的出图比例(即感光传感器在宽度方向和高度方向形成的图像的比例)相匹配，这样可以尽量使得实时取景框504和目标取景框503的取景范围最大。In some embodiments, the size ratio of the live view frame 504 (i.e. the ratio of the two adjacent sides of the live view frame 504) and the size ratio of the target view frame 503 (i.e. the ratio of the two adjacent sides of the target view frame 503) can be compared with the telephoto The image output ratio of the photosensitive sensor of the camera (that is, the ratio of the image formed by the photosensitive sensor in the width direction and the height direction) matches, so that the viewing range of the real-
在长焦辅助预览界面上，用户可以通过辅助取景框502、目标取景框503和实时取景框504，实时、直观地浏览和对比辅助摄像头采集到的预览图像，目标对象以及长焦摄像头采集到的预览图像。On the telephoto auxiliary preview interface, the user can browse and compare the preview image collected by the auxiliary camera, the target object and the image collected by the telephoto camera in real time and intuitively through the
在一些实施例中，手机可以通过陀螺仪、加速度传感器等传感器确定当前实时的运动姿态。该运动姿态可以包或手机倾斜角度和所处位置等信息。手机根据目标取景框503中指定的目标对象，计算长焦摄像头锁定(或称可拍摄到)目标对象时，即目标对象在长焦摄像头的取景范围内时，手机对应的目标运动姿态。而后，手机可以根据当前实时的运动姿态和目标运动姿态，计算手机从当前实时的运动姿态到目标运动姿态之间的偏移距离，偏移方向、偏转角度等调整信息。手机可以根据调整信息对用户进行提示，以引导用户将手机移动(包括平移、翻转等)到目标运动姿态，从而使得目标对象置于长焦摄像头的取景范围内，使得长焦摄像头可以锁定目标对象，从而进行图像拍摄。In some embodiments, the mobile phone can determine the current real-time motion posture through sensors such as a gyroscope and an acceleration sensor. The motion gesture may include information such as the tilt angle and location of the mobile phone. According to the target object specified in the
例如，当前实时的运动姿态为图1C所示的运动姿态，目标对象为待拍摄对象1。示例性的，待拍摄对象1可以为图5C中目标取景框503中的目标对象。For example, the current real-time motion posture is the motion posture shown in FIG. 1C , and the target object is the object 1 to be photographed. Exemplarily, the object 1 to be photographed may be the target object in the
如图1C所示，待拍摄对象1并不在长焦摄像头取景范围内。对应到图5C所示的长焦辅助预览界面上可知，实时取景框504内采集到的预览图像并不包括目标对象。As shown in FIG. 1C , the subject 1 to be photographed is not within the viewing range of the telephoto camera. Corresponding to the telephoto auxiliary preview interface shown in FIG. 5C , it can be known that the preview image captured in the real-
若要使得长焦摄像头拍摄到待拍摄对象1，则如图1D所示，待拍摄对象1需要置于长焦摄像头的取景范围内。这样，长焦摄像头采集到的预览图像才能包括待拍摄对象1。也就是说，手机需要处于如图1D所示的目标运动姿态，才能使得待拍摄对象1置于长焦摄像头的取景范围内，从而使得长焦摄像头能够锁定待拍摄对象1。To enable the telephoto camera to capture the object 1 to be photographed, as shown in FIG. 1D , the object 1 to be photographed needs to be placed within the viewing range of the telephoto camera. In this way, the preview image collected by the telephoto camera can include the subject 1 to be photographed. That is to say, the mobile phone needs to be in the target motion posture as shown in FIG. 1D so that the subject 1 to be photographed can be placed within the viewing range of the telephoto camera, so that the telephoto camera can lock the subject 1 to be photographed.
在一些技术方案中，手机可以根据长焦摄像头当前采集到的预览图像的内容，在辅助预览图像上的位置(该位置可以称为参考位置)，与辅助预览图像上目标对象的位置之间的相对关系，以及手机当前实时的运动姿态，确定目标对象移动到参考位置时，即长焦摄像头可拍摄到目标对象时，手机对应的目标运动姿态。In some technical solutions, the mobile phone may be based on the content of the preview image currently collected by the telephoto camera, the position on the auxiliary preview image (this position may be called a reference position), and the position of the target object on the auxiliary preview image. The relative relationship, as well as the current real-time motion posture of the mobile phone, determine the target motion posture of the mobile phone when the target object moves to the reference position, that is, when the telephoto camera can capture the target object.
在另一些技术方案中，手机可以确定实时取景框中，长焦摄像头采集到的预览图像中的内容，在实际空间中的第一位置，与目标取景框中的目标对象在实际空间中的第二位置之间的相对关系。从而根据该相对关系以及手机当前的实时运动姿态，确定长焦摄像头锁定第二位置的目标对象时，手机对应的目标运动姿态。In some other technical solutions, the mobile phone can determine the first position in the actual space of the content in the preview image collected by the telephoto camera in the real-time viewfinder frame, and the first position in the actual space of the target object in the target viewfinder frame. The relative relationship between the two positions. Therefore, according to the relative relationship and the current real-time motion posture of the mobile phone, when the telephoto camera locks the target object at the second position, the corresponding target motion posture of the mobile phone is determined.
在另一些技术方案中，由于不同摄像头的取景范围不同，因而不同摄像头采集到的预览图像可以对应显示区域的不同区域范围。例如，如图6所示，辅助摄像头的取景范围可以与整个辅助取景框601对应。长焦摄像头的取景范围可以与区域602对应。这样，实时取景框504内显示的长焦摄像头采集到的预览图像的内容，在辅助预览图像上的位置位于区域602内。当目标取景框603中的目标对象不在长焦摄像头的取景范围内时，辅助预览图像上的目标对象在区域602之外。当目标取景框603中的目标对象在长焦摄像头的取景范围内时，辅助预览图像上的目标对象在区域602内。手机可以根据当前辅助预览图像上目标对象与区域602的相对位置以及当前实时的运动姿态，确定目标对象位于区域602中时手机对应的目标运动姿态。In some other technical solutions, since different cameras have different viewing ranges, the preview images collected by different cameras may correspond to different ranges of the display area. For example, as shown in FIG. 6 , the viewing range of the auxiliary camera may correspond to the entire
在一些实施例中，长焦摄像头的取景范围可以与辅助摄像头的取景范围的中心区域重叠。这样，区域602可以为显示区域的中心区域。也即，区域602可以为辅助取景框601的中心区域。In some embodiments, the viewing range of the telephoto camera may overlap with the central area of the viewing range of the auxiliary camera. As such,
从而，手机可以根据当前实时的运动姿态与目标运动姿态之间的差值确定调整信息，并根据调整信息提示用户移动手机。手机根据调整信息对用户进行提示的方法可以有多种。Therefore, the mobile phone can determine adjustment information according to the difference between the current real-time motion posture and the target motion posture, and prompt the user to move the mobile phone according to the adjustment information. There may be multiple methods for the mobile phone to prompt the user according to the adjustment information.
例如，在一些实施例中，手机可以显示提示标识，以指引用户移动手机。例如，该提示标识可以指引用户移动手机的方向。比如，指引用户向上、下、左、右、左上或右下等方向移动手机。示例性的，参见图7A，该提示标识为箭头701。该箭头701所指示的方向即为指引用户移动手机的方向。该箭头701指引用户向左移动手机。再示例性的，参见图7B，该提示标识为箭头702，该箭头702指引用户向左下方移动手机。再示例性的，参见图7C，该提示标识为文字信息703。该文字信息703提示用户“请向左下方移动手机”。For example, in some embodiments, the mobile phone may display prompt signs to guide the user to move the mobile phone. For example, the prompt logo can guide the user to move the mobile phone. For example, guide the user to move the mobile phone in directions such as up, down, left, right, upper left or lower right. For example, referring to FIG. 7A , the prompt is identified as an
需要说明的是，该提示信息可以给用户以大致方向上的指引，避免用户盲目地向四周搜索目标对象导致的长时间的搜寻过程，减少长焦摄像头锁定目标对象的时间，提高用户使用体验。It should be noted that the prompt information can guide the user in the general direction, avoid the long search process caused by the user blindly searching for the target object around, reduce the time for the telephoto camera to lock the target object, and improve the user experience.
需要注意的是，在实际拍摄过程中，用户在根据提示标识移动手机的过程中，通常会自然地翻转手机。用户根据实时取景框和目标取景框中的内容在辅助取景框中的相对位置，或者根据实际三维空间中目标对象的位置，进行主观判断，从而在移动手机的过程中主动翻转手机，以使得长焦摄像头能够更快地锁定目标对象。It should be noted that, in the actual shooting process, the user usually turns the mobile phone over naturally during the process of identifying and moving the mobile phone according to the prompt. The user makes subjective judgments based on the relative positions of the real-time viewfinder frame and the content in the target viewfinder frame in the auxiliary viewfinder frame, or according to the position of the target object in the actual three-dimensional space, and actively flips the mobile phone over during the process of moving the mobile phone, so that the long-term The focus camera can lock on to the target object faster.
在另一些实施例中，该提示标识还可以指引用户移动手机的幅度，使得用户获知移动距离的大小，从而给用户以更为精确地指引，使得用户和长焦摄像头能够更为快速地锁定目标对象，减少用户搜寻目标对象的时间。In other embodiments, the prompt mark can also guide the user to move the mobile phone, so that the user can know the size of the moving distance, so as to give the user more accurate guidance, so that the user and the telephoto camera can lock the target more quickly objects, reducing the time for users to search for target objects.
例如，该提示标识为箭头，该箭头的大小用户表示指引用户移动手机的距离。当用户朝正确方向移动手机时，该箭头变小(或变短)；当用户向错误方向移动手机时，该箭头变大(或变长)。再例如，该提示标识为文字信息，该文字信息可以为：“请向左偏下30°方向，移动2cm”。For example, the prompt is identified as an arrow, and the size of the arrow indicates the distance to guide the user to move the mobile phone. When the user moves the phone in the correct direction, the arrow becomes smaller (or shorter); when the user moves the phone in the wrong direction, the arrow becomes larger (or longer). For another example, the prompt is identified as text information, and the text information may be: "Please move 2 cm to the left in a downward direction of 30°".
在另一些实施例中，该提示标识还可以指示用户翻转手机的角度是否正确，从而给用户以更为精确地指引，使得用户和长焦摄像头能够更为快速地锁定目标对象。若用户移动手机的方向正确，且翻转手机的方向也正确，则该箭头变小(或变短)。若用户移动手机的方向正确，但用户翻转手机的方向不正确，则该箭头不变小(或变短)。在用户调整手机的翻转方向后，该箭头才会变小(或变短)。In some other embodiments, the prompt mark can also indicate whether the angle at which the user flips the mobile phone is correct, so as to provide the user with more accurate guidance, so that the user and the telephoto camera can lock the target object more quickly. The arrow becomes smaller (or shorter) if the user is moving the phone in the correct direction and flipping the phone in the correct direction. If the direction in which the user moves the phone is correct, but the direction in which the user flips the phone is incorrect, the arrow does not become smaller (or becomes shorter). The arrow will only get smaller (or shorter) after the user adjusts the flip orientation of the phone.
在另一些实施例中，手机可以通过语音对用户进行持续引导。例如，手机可以语音指示用户“向右上方移动”、“向下移动”等。In other embodiments, the mobile phone can continuously guide the user through voice. For example, the mobile phone can voice instruct the user to "move up to the right", "move down" and so on.
在其他一些实施例中，该提示标识可以对用户调整手机的运动姿态在三维空间内进行提示，从而给用户以更为精确地指引，使得用户和长焦摄像头能够更为快速地锁定目标对象，减少用户搜寻目标对象的时间。例如，提示内容可以包括手机的移动方向和翻转方向。示例性的，参见图7D，该提示标识包括箭头704和箭头705。该箭头704用于提示用户向左移动手机。该箭头705用于提示用户向触摸屏的前方(即具有显示功能的一方)翻转手机。再示例性的，该提示标识为语音提示信息“请向左移动手机，并向触摸屏的前方翻转大约20°”。In some other embodiments, the prompt mark can prompt the user to adjust the motion posture of the mobile phone in the three-dimensional space, thereby giving the user more accurate guidance, so that the user and the telephoto camera can lock the target object more quickly, Reduce the time for users to search for target objects. For example, the prompt content may include the moving direction and the flipping direction of the mobile phone. Exemplarily, referring to FIG. 7D , the prompt mark includes an arrow 704 and an
若用户通过拖动目标取景框，修改了目标对象，则手机还可以根据修改后的目标对象确定调整信息，并根据调整信息对用户进行提示，以指引用户移动手机。If the user modifies the target object by dragging the target viewfinder frame, the mobile phone can also determine adjustment information according to the modified target object, and prompt the user according to the adjustment information to guide the user to move the mobile phone.
在用户根据提示信息的引导移动手机的过程中，目标对象越来越接近长焦摄像头的取景范围。实时取景框中显示的长焦摄像头实时采集到的预览图像，与目标取景框中的目标对象的图像越来越相似。During the process of the user moving the mobile phone according to the guidance of the prompt information, the target object is getting closer and closer to the field of view of the telephoto camera. The preview image captured in real time by the telephoto camera displayed in the real-time viewfinder is more and more similar to the image of the target object in the target viewfinder.
手机在移动后，可以确定目标对象是否在长焦摄像头的取景范围内，即长焦摄像头是否锁定目标对象。例如，手机在确定当前实时的运动姿态与目标运动姿态相匹配时，目标对象基本在长焦摄像他的取景范围内，即确定长焦摄像头基本锁定目标对象。示例性的，手机在确定当前实时的运动姿态与目标运动姿态的相似度大于预设值4(例如90％)时，可以确定当前实时的运动姿态与目标运动姿态相匹配。After the mobile phone moves, it can determine whether the target object is within the viewing range of the telephoto camera, that is, whether the telephoto camera locks on the target object. For example, when the mobile phone determines that the current real-time motion posture matches the target motion posture, the target object is basically within the viewing range of the telephoto camera, that is, it is determined that the telephoto camera basically locks on the target object. Exemplarily, when the mobile phone determines that the similarity between the current real-time motion posture and the target motion posture is greater than a preset value 4 (for example, 90%), it may determine that the current real-time motion posture matches the target motion posture.
手机确定长焦摄像头锁定目标对象后，可以切换到显示长焦预览界面。After the mobile phone determines that the telephoto camera has locked the target object, it can switch to display the telephoto preview interface.
需要注意的是，手机确定长焦摄像头锁定目标对象的方法还可以其他多种方式。例如，手机通过图像识别技术，确定实时取景框504中的图像与目标取景框503中的图像的内容相匹配时，确定长焦摄像头基本锁定目标对象，从而切换到显示长焦预览界面。例如，手机可以计算实时取景框504中的图像和目标取景框503中的图像的相似度。若该相似度大于或者等于预设值5(例如80％)，则手机可以确定长焦摄像头基本锁定目标对象。It should be noted that the method for the mobile phone to determine the target object locked by the telephoto camera can also be in other ways. For example, when the mobile phone determines that the content of the image in the real-
例如，基于图像识别进行图像匹配的算法可以包括基于灰度的模板匹配算法，基于特征的匹配算法，光流法等。例如，基于灰度的模板匹配算法可以包括平均绝对差算法(sum of absolute differences，MAD)、绝对误差和算法(sum of squared differences，SAD)、平均误差平方和算法(mean square differences，MSD)、序贯相似性检测算法(sequential similiarity detection algorithm，SSDA)等。For example, the algorithm for image matching based on image recognition may include template matching algorithm based on gray scale, matching algorithm based on feature, optical flow method and so on. For example, grayscale-based template matching algorithms may include mean absolute difference algorithm (sum of absolute differences, MAD), absolute error sum algorithm (sum of squared differences, SAD), mean square difference algorithm (mean square differences, MSD), Sequential similarity detection algorithm (sequential similiarity detection algorithm, SSDA), etc.
一般地，通过图像识别技术确定图像之间的相似度，需要进行卷积等复杂计算，因而消耗的计算资源较多，计算速度较慢。与图像识别相比，通过陀螺仪等传感器采集的数据计算实时运动姿态与目标运动姿态之间的相似度较为简单，所需的计算量较少，计算速度较快。Generally, determining the similarity between images through image recognition technology requires complex calculations such as convolution, which consumes more computing resources and is slower in computing speed. Compared with image recognition, it is relatively simple to calculate the similarity between the real-time motion posture and the target motion posture through the data collected by sensors such as gyroscopes, and requires less calculation and faster calculation speed.
手机切换到显示长焦预览界面后，可以在长焦预览界面上全屏显示长焦摄像头采集到的预览图像。长焦预览界面上不再显示辅助预览图像和目标取景框。After the mobile phone switches to displaying the telephoto preview interface, the preview image collected by the telephoto camera can be displayed in full screen on the telephoto preview interface. The auxiliary preview image and target viewfinder frame are no longer displayed on the telephoto preview interface.
长焦预览界面上图像的尺寸比例与实时取景框中图像的尺寸比例，可以一致，也可以不一致。长焦预览界面上不再显示目标取景框和实时取景框。The size ratio of the image on the telephoto preview interface and the size ratio of the image in the real-time viewfinder frame may or may not be the same. The target viewfinder frame and live viewfinder frame are no longer displayed on the telephoto preview interface.
在一种情况下，切换到场景预览界面后，长焦预览界面上的预览图像的变焦倍率为默认的变焦倍率。用户可以在设置界面修改该默认的变焦倍率的大小。在另一种情况下，切换到长焦预览界面后，长焦预览界面上的预览图像的变焦倍率，与切换前目标取景框的大小对应的变焦倍率一致。In one case, after switching to the scene preview interface, the zoom magnification of the preview image on the telephoto preview interface is the default zoom magnification. The user can modify the size of the default zoom ratio in the setting interface. In another case, after switching to the telephoto preview interface, the zoom magnification of the preview image on the telephoto preview interface is consistent with the zoom magnification corresponding to the size of the target viewfinder frame before switching.
在一些实施例中，长焦预览界面包括拍摄控件。示例性的，参见图8A，手机检测到用户在长焦预览界面上点击拍摄控件801的操作后，拍摄图像。In some embodiments, the telephoto preview interface includes shooting controls. For example, referring to FIG. 8A , the mobile phone captures an image after detecting that the user clicks the
在另一些实施例中，长焦预览界面可以参见图8B或图8C，手机在切换到显示长焦预览界面后，自动拍摄一张或多张图像，从而可以节省用户指示拍摄的操作。In other embodiments, the telephoto preview interface can be referred to in FIG. 8B or 8C. After switching to displaying the telephoto preview interface, the mobile phone automatically captures one or more images, thereby saving the user from instructing the shooting operation.
其中，由于手的抖动或其他原因，在切换到显示长焦预览界面后，目标对象可能会偏离屏幕中心或无法出现在长焦预览界面上(即目标对象丢失)，使得长焦摄像头不能锁定目标对象。示例性的，长焦预览界面可以如图9A或图9B所示。Among them, due to hand shaking or other reasons, after switching to displaying the telephoto preview interface, the target object may deviate from the center of the screen or cannot appear on the telephoto preview interface (that is, the target object is lost), so that the telephoto camera cannot lock the target object. Exemplarily, the telephoto preview interface may be as shown in FIG. 9A or FIG. 9B .
因而，在另一些实施例中，在切换到显示长焦预览界面后，手机可以继续确定当前实时的运动姿态。若当前实时的运动姿态与目标运动姿态不匹配；或者，若长焦摄像头实时采集到的预览图像与目标取景框中的图像不匹配，则采用上述实施例中描述的方式继续提示用户移动手机，以便长焦摄像头可以重新锁定目标对象。示例性的，用于提示用户移动手机的提示标识可以为图9A中的箭头901，或者图9B中的箭头902。Therefore, in some other embodiments, after switching to displaying the telephoto preview interface, the mobile phone can continue to determine the current real-time motion gesture. If the current real-time motion posture does not match the target motion posture; or, if the preview image collected by the telephoto camera in real time does not match the image in the target viewfinder frame, then continue to prompt the user to move the mobile phone in the manner described in the above-mentioned embodiment, So that the telephoto camera can re-lock on the target object. Exemplarily, the prompt sign used to prompt the user to move the mobile phone may be the arrow 901 in FIG. 9A or the
在切换到显示长焦预览界面后，若当前实时的运动姿态与目标运动姿态相匹配；或者，若长焦摄像头实时采集到的预览图像与目标取景框中的图像相匹配。或者，若用户根据手机的引导移动手机，使得当前实时的运动姿态与目标运动姿态相匹配；或者，使得长焦摄像头实时采集到的预览图像与目标取景框中的图像相匹配。则，在一种技术方案中，手机自动拍摄图像。在另一种技术方案中，手机可以停止对用户进行提示，并在检测到用户指示拍摄的操作后，再拍摄图像。在另一种技术方案中，手机可以通过显示信息、语音、振动等方式提示用户已锁定目标对象，在检测到用户指示拍摄的操作后，拍摄图像。After switching to displaying the telephoto preview interface, if the current real-time motion posture matches the target motion posture; or, if the preview image captured by the telephoto camera in real time matches the image in the target viewfinder frame. Or, if the user moves the mobile phone according to the guidance of the mobile phone, the current real-time motion posture matches the target motion posture; or, the preview image collected by the telephoto camera in real time matches the image in the target viewfinder frame. Then, in a technical solution, the mobile phone automatically captures images. In another technical solution, the mobile phone may stop prompting the user, and capture an image after detecting an operation instructed by the user to capture. In another technical solution, the mobile phone can prompt the user that the target object has been locked by means of display information, voice, vibration, etc., and capture an image after detecting the operation instructed by the user to shoot.
其中，由于自动拍摄是在当前实时的运动姿态与目标运动姿态匹配时，或者实时取景框504中的图像与目标取景框503中的图像匹配时自动进行的，因而拍摄到的对象是用户指定的目标对象，并且可以节省用户的操作，提高拍摄效率和用户使用体验。Wherein, since the automatic shooting is carried out automatically when the current real-time motion posture matches the target motion posture, or when the image in the real-
手机在拍摄图像后，若目标对象发生偏离(即目标对象不在拍摄的图像的中心)或丢失(即未拍摄到目标对象，拍摄的图像上未出现目标对象)，使得长焦摄像头不再锁定目标对象，则手机还可以采用上述实施例中描述的方式继续引导用户，以使得长焦摄像头可以重新锁定目标对象。尤其地，在手机自动拍摄图像后，自动拍摄的图像效果可能不太理想，用户还可以继续根据手机的引导移动手机，从而在重新锁定目标对象后，手动拍摄一张或多张效果更好的图像。After the mobile phone captures an image, if the target object deviates (that is, the target object is not in the center of the captured image) or is lost (that is, the target object is not captured, and the target object does not appear on the captured image), the telephoto camera will no longer lock the target object, the mobile phone may continue to guide the user in the manner described in the above embodiments, so that the telephoto camera can re-lock the target object. In particular, after the mobile phone automatically takes an image, the effect of the automatically taken image may not be ideal, and the user can continue to move the phone according to the guidance of the mobile phone, so that after re-locking the target object, manually take one or more pictures with better results image.
在一些实施例中，在切换到显示长焦预览界面后，若用户想要更改目标对象，则手机可以先退出长焦辅助模式。示例性的，手机检测到用户点击图8B中的“×”的操作后，可以退出长焦辅助模式。在手机再次进入长焦辅助模式后，用户通过目标取景框重新指定新的目标对象。In some embodiments, after switching to displaying the telephoto preview interface, if the user wants to change the target object, the mobile phone may first exit the telephoto assist mode. Exemplarily, after the mobile phone detects that the user clicks the "×" in FIG. 8B , it can exit the telephoto assist mode. After the mobile phone enters the telephoto assist mode again, the user redesignates a new target object through the target viewfinder frame.
在另一些实施例中，在切换到显示长焦预览界面后，若用户想要更改目标对象，则手机可以退出长焦预览界面，返回显示上述包括目标取景框的长焦辅助预览界面，从而通过目标取景框重选指定新的目标对象。示例性的，手机在显示长焦预览界面的情况下，检测到用户点击返回(back)键的操作后，可以返回显示包括目标取景框的长焦辅助预览界面。In other embodiments, after switching to displaying the telephoto preview interface, if the user wants to change the target object, the mobile phone can exit the telephoto preview interface and return to display the above-mentioned telephoto auxiliary preview interface including the target viewfinder frame, thereby passing The target frame reselects to specify a new target object. Exemplarily, when the mobile phone is displaying the telephoto preview interface, after detecting that the user clicks the back (back) button, it may return to display the telephoto auxiliary preview interface including the target viewfinder frame.
在其他一些场景下，目标对象是运动的。例如，目标对象是持续运动的。再例如，在显示长焦辅助预览界面后，目标对象突然开始运动。再例如，在切换到显示长焦预览界面后，目标对象突然开始运动等情况。In other scenarios, the target object is moving. For example, the target object is in continuous motion. For another example, after the telephoto auxiliary preview interface is displayed, the target object suddenly starts to move. For another example, after switching to displaying the telephoto preview interface, the target object suddenly starts to move.
在目标对象处于运动状态的情况下，用户和长焦摄像头更容易丢失目标对象。在一些实施例中，手机可以实时追踪运动状态的目标对象。长焦辅助预览界面上的目标取景框可以随着目标对象的移动而实时移动。并且，手机可以计算运动状态的目标对象所对应的实时目标运动姿态。手机根据当前实时运动姿态与实时目标运动姿态之间的差值，计算实时的调整信息，从而根据实时的调整信息，实时调整对用户的提示信息，从而引导用户移动手机。The user and the telephoto camera are more likely to lose the target object when the target object is in motion. In some embodiments, the mobile phone can track the moving target object in real time. The target viewfinder frame on the telephoto auxiliary preview interface can move in real time as the target object moves. In addition, the mobile phone can calculate the real-time target motion posture corresponding to the target object in the motion state. The mobile phone calculates real-time adjustment information according to the difference between the current real-time motion posture and the real-time target motion posture, so as to adjust the prompt information to the user in real time according to the real-time adjustment information, thereby guiding the user to move the mobile phone.
与上述实施例描述的过程类似，在手机显示长焦预览界面的情况下，在当前实时运动姿态与实时目标运动姿态相匹配时，或者在实时取景框504中的图像与目标取景框503中的图像的内容相匹配时，手机确定长焦摄像头基本锁定目标对象，从而切换到显示长焦预览界面。Similar to the process described in the above embodiment, when the mobile phone displays the telephoto preview interface, when the current real-time motion posture matches the real-time target motion posture, or the image in the real-
与上述实施例描述的过程类似，在切换到显示长焦预览界面后，手机可以自动拍摄图像。Similar to the process described in the above embodiment, after switching to displaying the telephoto preview interface, the mobile phone can automatically capture an image.
或者，与上述实施例描述的过程类似，在切换到显示长焦预览界面后，手机可以在后台继续采集辅助预览图像，并实时追踪目标对象。若当前实时运动姿态与实时目标运动姿态相匹配，或者若长焦摄像头当前采集到的预览图像与实时追踪到的目标对象的图像相匹配时，可以触发手机自动拍摄图像。从而，可以辅助用户使用长焦镜头拍摄动态的目标对象。Or, similar to the process described in the above embodiment, after switching to displaying the telephoto preview interface, the mobile phone can continue to collect auxiliary preview images in the background and track the target object in real time. If the current real-time motion posture matches the real-time target motion posture, or if the preview image currently collected by the telephoto camera matches the image of the target object tracked in real time, the mobile phone can be triggered to automatically capture an image. Therefore, the user can be assisted to shoot a dynamic target object with a telephoto lens.
需要说明的是，在目标对象处于运动状态的情况下，手机自动拍摄图像，可以及时拍摄到目标对象，避免用户还未来得及点击拍摄控件，拍摄目标物体已经跑出长焦摄像头的取景范围。It should be noted that when the target object is in motion, the mobile phone automatically captures images, and the target object can be captured in time, preventing the user from clicking the shooting control in the future, and the target object has already run out of the viewfinder range of the telephoto camera.
并且，在目标对象处于运动状态的情况下，在长焦辅助预览界面上，手机还可以显示运动标记。例如，该运动标记可以用于表示目标对象的运动方向，目标对象的轮廓等。运动标记可以方便用户直观地获知目标对象的大小、位置及运动方向等信息。示例性的，图10A示出了一种运动标记1001的示意图。运动标记1001中的椭圆形虚线用于标记运动的目标对象的轮廓和大小。运动标记1001中的箭头用于标记目标对象的运动方向。再示例性的，图10B示出了一种运动标记1002的示意图。运动标记1002中的“[]”用于标记运动的目标对象的轮廓和大小。运动标记1002中的箭头用于标记目标对象的运动方向。Moreover, when the target object is in motion, the mobile phone can also display motion marks on the telephoto auxiliary preview interface. For example, the motion marker can be used to represent the motion direction of the target object, the outline of the target object, and the like. The motion marker can facilitate the user to intuitively know the size, position and motion direction of the target object and other information. Exemplarily, FIG. 10A shows a schematic diagram of a
以上主要是以手机指引用户采用长焦摄像头进行拍照为例进行说明的。在录像过程中，用户也可以指定目标对象。手机也可以采用以上实施例描述的方法给用户以提示，以指引用户在采用长焦摄像头录像时移动手机，从而帮助用户使用长焦摄像头尽量锁定目标对象，进而对目标对象进行追踪录像。The above description is mainly based on an example in which the mobile phone guides the user to take pictures with the telephoto camera. During the video recording, the user can also specify the target object. The mobile phone can also use the method described in the above embodiments to give the user a prompt to guide the user to move the mobile phone when using the telephoto camera to record video, thereby helping the user to use the telephoto camera to lock the target object as much as possible, and then track and record the target object.
示例性的，参见图11A，在进入长焦辅助模式后，长焦辅助预览界面上可以包括第一控件1101和第二控件1102。手机检测到用户点击第一控件1101的操作后，进入长焦辅助拍照子模式，手机可以指引用户进行移动，以使得长焦摄像头锁定目标对象并拍摄照片。For example, referring to FIG. 11A , after entering the telephoto assist mode, the telephoto assist preview interface may include a
手机检测到用户点击第二控件1102的操作后，如图11B所示，手机可以进入长焦辅助录像子模式。在长焦辅助录像子模式下，手机可以指引用户进行移动，以使得长焦摄像头尽量锁定目标对象。After the mobile phone detects that the user clicks on the
手机检测到用户点击录像控件1103的操作后，开始录像。在录像过程中，尤其在对运动状态下的目标对象进行录像的过程中，参见图11C，手机可以指引用户移动手机，以使得用户采用长焦摄像头能够尽量锁定目标对象，从而达到实时追踪目标对象，对目标对象进行录像的目的。After the mobile phone detects that the user clicks on the recording control 1103, it starts recording. During the recording process, especially during the recording process of the target object in motion, see Figure 11C, the mobile phone can guide the user to move the mobile phone, so that the user can use the telephoto camera to lock the target object as much as possible, so as to achieve real-time tracking of the target object , the purpose of recording the target object.
此外，本申请实施例提供的通过引导电子设备进行移动，辅助电子设备的长焦摄像头锁定目标对象从而拍摄图像的方法，还可以应用于其他多种场景。例如，在多摄像头监控装置中，用于监控的多个摄像头包括广角摄像头和长焦摄像头。广角摄像头的监控区域广，通过图像识别技术，监控装置可以捕捉可疑或需要重点监控的区域，即相当于上述目标对象。监控装置可以指引长焦摄像头进行移动，从而锁定并拍摄可疑或需要重点监控区域的画面。In addition, the method of guiding the electronic device to move and assisting the telephoto camera of the electronic device to lock the target object and capture an image provided by the embodiment of the present application can also be applied to other various scenarios. For example, in a multi-camera surveillance device, the multiple cameras used for surveillance include a wide-angle camera and a telephoto camera. The monitoring area of the wide-angle camera is wide. Through image recognition technology, the monitoring device can capture suspicious areas or areas that need to be monitored, which are equivalent to the above-mentioned target objects. The monitoring device can guide the telephoto camera to move, so as to lock and take pictures of suspicious or key monitoring areas.

1201、电子设备启动相机。1201. The electronic device starts the camera.
1202、电子设备采用第一摄像头和第二摄像头分别采集第一预览图像和第二预览图像，第二摄像头为长焦摄像头，第一摄像头的取景范围大于第二摄像头的取景范围。1202. The electronic device uses a first camera and a second camera to capture a first preview image and a second preview image respectively, the second camera is a telephoto camera, and the viewing range of the first camera is larger than that of the second camera.
1203、电子设备显示第一预览界面，第一预览界面包括第一取景框、第二取景框和第三取景框；第一取景框用于显示第一预览图像；第二取景框内的图像为第一预览图像上的一部分；第二取景框中的内容为第二摄像头待拍摄的目标对象；第三取景框用于显示第二预览图像。1203. The electronic device displays a first preview interface. The first preview interface includes a first viewing frame, a second viewing frame, and a third viewing frame; the first viewing frame is used to display a first preview image; the image in the second viewing frame is A part of the first preview image; the content in the second viewfinder frame is the target object to be photographed by the second camera; the third viewfinder frame is used to display the second preview image.
1204、电子设备显示第一提示信息，第一提示信息用于引导用户移动电子设备，以使得电子设备移动后第二摄像头可锁定目标对象。1204. The electronic device displays first prompt information, where the first prompt information is used to guide the user to move the electronic device, so that the second camera can lock the target object after the electronic device moves.
这样，在电子设备由广角摄像头或中焦摄像头等第一摄像头切换到长焦摄像头即第二摄像头后，电子设备可以通过提示信息指引用户移动电子设备。以便，在电子设备移动后，长焦摄像头能够快速锁定目标对象。进而，电子设备可以采用长焦摄像头拍摄目标对象的图像。In this way, after the electronic device switches from a first camera such as a wide-angle camera or a medium-focus camera to a second camera that is a telephoto camera, the electronic device can guide the user to move the electronic device through prompt information. So that, after the electronic device moves, the telephoto camera can quickly lock the target object. Furthermore, the electronic device may use a telephoto camera to capture an image of the target object.
在一些实施例中，在电子设备显示第一预览界面之后，该方法还可以包括：电子设备检测到用户针对第二取景框的拖动操作。电子设备响应于拖动操作，在第一预览图像上移动第二取景框，目标对象随着第二取景框位置的变化而变化。即，在拍摄场景下，用户可以指定目标对象。In some embodiments, after the electronic device displays the first preview interface, the method may further include: the electronic device detects a user's drag operation on the second viewfinder frame. The electronic device moves the second viewfinder frame on the first preview image in response to the drag operation, and the target object changes along with the change of the position of the second viewfinder frame. That is, in a shooting scene, the user can designate a target object.
这样，在电子设备由广角摄像头或中焦摄像头等摄像头切换到长焦摄像头后，电子设备可以根据用户指定的目标对象，指引用户移动电子设备。以便，用户可以根据该指引移动电子设备，从而使得电子设备移动后长焦摄像头能够快速锁定目标对象。In this way, after the electronic device switches from a wide-angle camera or a medium-focus camera to a telephoto camera, the electronic device can guide the user to move the electronic device according to the target object specified by the user. So that the user can move the electronic device according to the guidance, so that the telephoto camera can quickly lock the target object after the electronic device moves.
