Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "and/or" herein is an association relationship describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.

The terms "first," "second," "third," and "fourth," etc. in the description and in the claims of the present application are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first input, the second input, the third input, the fourth input, etc. are used to distinguish between different inputs, rather than to describe a particular order of inputs.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of processing units means two or more processing units; plural elements means two or more elements, and the like.

Background blurring: i.e. making the depth of field shallow, focusing the focus on the subject.

Background blurring image: the shot subject is clear, and the background is blurred. Here, the background is theoretically the contents of the shot other than the subject of the shot. In practice, the background may be the shot content whose distance from the subject is inconsistent (i.e., the shot content whose distance from the camera is inconsistent with the distance from the subject to the camera). That is, in the background blurring shooting mode, the shot background blurring image is an image in which the subject and the content of the shot that is at the same distance from the subject are clear, and the other content of the shot that is at a different distance from the subject is blurred. However, in practice, when an image recognition algorithm (recognizing the subject) or a background blurring algorithm (blurring the contents of the image other than the subject) is added to the background blurring image capturing mode, the background blurring image captured may be an image in which the subject is clear and the contents of the image other than the subject are blurred.

In the embodiment of the present invention, the target image may be a background blurring image in any of the above cases.

The embodiment of the invention provides a shooting method, wherein electronic equipment can receive a first input; responding to the first input, controlling the second camera to move, and acquiring a target image according to a first preview image acquired by the first camera and a second preview image acquired by the second camera after moving; wherein, the first distance between the position of the second camera after moving and the target object is less than the distance between the first camera and the target object, and the first distance is less than or equal to the predetermined threshold, and the target image is: and an image in which the background is blurred and the target object is taken as a subject. According to the scheme, when a target image which takes the target object as a shooting main body and has a blurred background needs to be shot, a user can trigger the electronic equipment through first input to control the second camera to be close to the target object and move to a position where the distance between the second camera and the target object is smaller than or equal to a preset threshold value, and then the target image is obtained according to a first preview image collected by the first camera and a second preview image collected by the second camera after moving. The second camera after moving is closer to the target object, and the contour of the target object in the collected second preview image is clearer, so that the target image with better background blurring effect can be obtained, and the problem that the final background blurring effect of the background blurring image is poorer due to inaccurate contour of the shot main body obtained by the traditional background blurring technology is solved.

The following describes a software environment applied to the shooting method provided by the embodiment of the present invention, taking an android operating system as an example.

Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).

The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the shooting method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the shooting method may run based on the android operating system shown in fig. 1. That is, the processor or the electronic device may implement the shooting method provided by the embodiment of the present invention by running the software program in the android operating system.

The electronic device in the embodiment of the invention can be a mobile electronic device or a non-mobile electronic device. The mobile electronic device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile electronic device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.

The electronic equipment in the embodiment of the invention comprises the first camera and the movable second camera, wherein whether the first camera is movable or not is not limited. In the embodiment of the invention, the second camera is movable, and comprises a second camera which is not separated from the electronic equipment and a second camera which is separated from the electronic equipment. When the second camera is not separated from the electronic equipment, the second camera can be in communication interaction with the electronic equipment in a wired connection and/or wireless connection mode; after the second camera is separated from the electronic equipment, the second camera can communicate with the electronic equipment in a wireless connection mode. In the embodiment of the present invention, the electronic device may further include a first gyroscope (for measuring a shooting angle of the first camera), and the second camera may further include a second gyroscope (for measuring a shooting angle of the second camera).

An execution subject of the shooting method provided in the embodiment of the present invention may be the electronic device (including a mobile electronic device and a non-mobile electronic device), or may also be a functional module and/or a functional entity capable of implementing the method in the electronic device, which may be determined specifically according to actual use requirements, and the embodiment of the present invention is not limited. The following takes an electronic device as an example to exemplarily describe the shooting method provided by the embodiment of the invention.

Referring to fig. 2, an embodiment of the present invention provides a shooting method applied to an electronic device including a first camera and a movable second camera, where the method may includesteps 201 to 203 described below.

Step 201, the electronic device receives a first input.

Optionally, the first input may be a click input of the user on the screen of the electronic device, a slide input of the user on the screen of the electronic device, or other feasibility inputs, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

Illustratively, the click input may be any number of click inputs or multi-finger click inputs, such as a single click input, a double click input, a three click input, a double-finger click input, or a three-finger click input; the slide input may be a slide input in an arbitrary direction or a multi-finger slide input, for example, an upward slide input, a downward slide input, a leftward slide input, a rightward slide input, a two-finger slide input, or a three-finger slide input.

Step 202, the electronic device controls the second camera to move in response to the first input.

Optionally, in the embodiment of the present invention, the electronic device may control the second camera to move by responding to a first input of the user controlling the second camera to move; the electronic device may also automatically control the second camera to move when detecting that the distance between the electronic device and the target object is greater than a preset threshold. The preset threshold is greater than or equal to the predetermined threshold, the electronic device may determine a distance between the electronic device and the target object through a distance sensor (e.g., an infrared sensor, etc.), or determine the distance between the electronic device and the target object by analyzing a preview image acquired by the electronic device through a camera (a first camera, a second camera, or another camera), and any related technology may be referred to as a method for how the electronic device specifically acquires the distance between the electronic device and the target object, which is not described herein.

It should be noted that, in the embodiment of the present invention, the electronic device and the second camera control the second camera to move in a communication interaction manner. For example, the electronic device acquires movement information (how to move, where to move, or the like) of the second camera through the first input, and then transmits the movement information to the second camera; the second camera receives the movement information from the electronic device and moves according to the movement information.

And step 203, the electronic equipment acquires a target image according to the first preview image acquired by the first camera and the second preview image acquired by the second camera after moving.

Wherein, the first distance between the position of the second camera after moving and the target object is less than the distance between the first camera and the target object, and the first distance is less than or equal to the predetermined threshold, and the target image is: and an image in which the background is blurred and the target object is taken as a subject.

In the embodiment of the present invention, the target object is a shooting subject, and the predetermined threshold may be determined according to an actual use requirement, which is not limited in the embodiment of the present invention. When the distance between the second camera and the target object is smaller than or equal to the preset threshold value, the second preview image acquired by the second camera basically only comprises the target object and possibly comprises a small part of other objects, namely, the second preview image is basically an image of a shooting subject, and the small part is an image of a background except the shooting subject. The first preview image collected by the first camera is a full scene image of the shooting subject and the background.

Illustratively, when the user selects the background blurring shooting mode on the electronic device and aims at a shooting scene, the second camera is controlled to move (the second camera is controlled to be separated from the electronic device and move to a position where the distance from the target object is less than or equal to a preset threshold value) in response to the first input. The state of the second camera after moving is shown in fig. 3, the mark "0" indicates the electronic device, the mark "1" indicates the first camera, the mark "2" indicates the second camera, the mark "3" indicates the target object (i.e., the shooting subject), the distance from the second camera to the target object is less than or equal to a predetermined threshold, and the second camera basically only collects the image of the target object.

It can be understood that, because the second camera is closer to the photographic subject and has a smaller depth of field, the second preview image has a background blurring effect, that is, the image of the photographic subject is clearer, and the images of other backgrounds are more blurred, so that the electronic device can more accurately obtain the contour information of the photographic subject according to the second preview image, and thus a target image with a better background blurring effect (for example, the photographic subject is clearer, the boundary between the background content and the photographic subject is more accurate, and the background blurring effect is closer to the real situation) can be obtained based on the second preview image.

It should be noted that, in the embodiment of the present invention, the electronic device acquires the second preview image through communication interaction with the second camera. For example, after the second camera acquires the second preview image, the second camera sends the second preview image to the electronic device; the electronic device receives a second preview image from the second camera.

In the embodiment of the invention, the electronic equipment responds to the first input and controls the second camera to move according to the first input. After the second camera moves to a position where the distance from the target object is less than or equal to a predetermined threshold, the electronic device may obtain, by using an image processing method, a target image in which the target object is a subject to be photographed and the background is blurred, according to the first preview image acquired by the first camera and the second preview image acquired by the second camera.

Optionally, in this embodiment of the present invention, the electronic device may first obtain, according to the second preview image, contour information of the target object, and then, in combination with the contour information, perform background blurring processing on background content (content other than the target object in the first preview image) in the first preview image, so as to obtain a target image with the target object as a shooting subject and with a blurred background.

Illustratively, in conjunction with fig. 2, as shown in fig. 4, thestep 203 may be specifically implemented by the followingsteps 203a to 203 b.

And step 203a, the electronic equipment acquires first information according to the second preview image.

The first information is used to characterize a contour of the target object.

In the embodiment of the present invention, any related technology may be referred to as a method for how to obtain the contour information of the target object in the second preview image, which is not limited in the embodiment of the present invention and is not described herein again.

And 203b, the electronic device performs background blurring processing on the first preview image according to the first information to obtain the target image.

In the embodiment of the invention, the electronic equipment determines the contour information of the target object in the first preview image according to the first information, and then performs background blurring processing on the background content in the first preview image to obtain the target object. The background blurring processing method may refer to any related technology, and the embodiments of the present invention are not limited and are not described herein again.

In the embodiment of the invention, the second camera is closer to the target object, and the contour of the target object in the acquired second preview image is clearer, so that the contour information of the target object obtained according to the second preview image is more accurate, and the background blurring effect of the target object obtained by combining the first preview image is better.

Optionally, in this embodiment of the present invention, the electronic device may first obtain, according to the second preview image, contour information of the target object and an image of the target object, then perform, in combination with the contour information, background blurring processing on background content (content other than the target object in the first preview image) in the first preview image to obtain an intermediate image that takes the target object as a shooting subject and has a blurred background, and finally synthesize the image of the target object and the intermediate image to generate the target image that takes the target object as a shooting subject and has a blurred background.

Illustratively, referring to fig. 4, as shown in fig. 5, after thestep 203a, the shooting method provided by the embodiment of the present invention may further include astep 203c, where thestep 203b may be specifically realized by the followingsteps 203b 1-203 b 2.

And step 203c, the electronic equipment acquires the first image according to the second preview image.

The first image is an image of the target object.

In the embodiment of the present invention, any related technology may be referred to as a method for obtaining a target object in a second preview image, which is not limited in the embodiment of the present invention and is not described herein again.

Step 203b1, the electronic device performs background blurring processing on the first preview image according to the first information to obtain a second image.

The second image is an image in which the target object is a subject and the background is blurred. The second image is an intermediate image.

Step 203b2, the electronic device synthesizes the first image and the second image to obtain the target image.

In the embodiment of the present invention, any related technology may be referred to for a method for synthesizing the first image and the second image, which is not limited in the embodiment of the present invention and is not described herein again.

It should be noted that, in the embodiment of the present invention, the execution sequence of thestep 203c and the step 203b1 is not limited, for example, thestep 203c may be executed first, and then the step 203b1 may be executed; step 203b1 may be executed first, and then step 203c may be executed;step 203c and step 203b1 may also be performed simultaneously.

In the embodiment of the invention, because the second camera is closer to the target object, and the image of the target object in the second preview image (relative to the image of the target object in the first preview image) is relatively clear, the image of the target object obtained according to the second preview image is relatively clear, and the background blurring effect of the target object obtained by synthesizing the first image and the second image is relatively good.

Optionally, in the embodiment of the present invention, the electronic device may first obtain the first image according to the second preview image, then perform background blurring processing on the first preview image according to the first image to obtain the second image, and finally synthesize the first image and the second image to obtain the target image. In this embodiment of the present invention, the electronic device may further obtain the target image according to the first preview image and the second preview image by using other methods, which is not limited in this embodiment of the present invention.

Alternatively, the first input may be an input for triggering the electronic device to determine a subject (i.e., a target object) to be photographed, and then the electronic device automatically controls the second camera to move to a position where a distance from the target object is less than or equal to a predetermined threshold value according to the determined target object.

Illustratively, the first input is a user input to the target object in the third preview image; the third preview image is a preview image collected by the first camera or the second camera; referring to fig. 5, as shown in fig. 6, afterstep 202, the photographing method provided by the embodiment of the present invention may further includestep 204 described below.

And step 204, the electronic equipment updates the preview image acquired by the second camera into a second preview image.
