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 terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The shooting method, the shooting device, the electronic device and the readable storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

Please refer to fig. 1, which shows one of the flowcharts of the shooting method provided in the embodiment of the present application. The shooting method provided by the embodiment of the application can be applied to electronic equipment. In practice, the electronic device may be a smartphone, a tablet computer, a laptop, etc. The electronic device may have a camera application installed therein, and the camera application may have a photographing function.

The process of the shooting method provided by the embodiment of the application comprises the following steps:

step 101, controlling a camera to shoot N groups of images of N shot objects, wherein each group of images comprises an object image and a background image.

In the present embodiment, the execution subject of the video shooting method (the electronic apparatus described above) may be mounted with a camera. The execution body may control the camera to capture N sets of images of N photographic subjects. Wherein N is a positive integer. The N photographic subjects may be any N subjects in the video preview interface, such as people, animals, still, scenes, and the like. As an example, if the photographing preview interface displays a child, a woman, and a tree, at least one of the child, the woman, and the tree may be a photographing object. For each object, when the camera is controlled to shoot the shooting object, the shooting object can be shot after focusing.

In the present embodiment, N sets of images can be obtained by performing shooting for N subjects. Each set of images may include an object image and a background image. The object image may be an image area surrounded by an object contour of the photographic object, and the background image may be an image of an area other than the image area surrounded by the object contour in the photographic image. In addition, the object image may be an image including the image area, and the background image may be an image including an area other than the image area, for example, both the object image and the background image may include all image contents in the video preview interface.

In some optional implementations of this embodiment, before controlling the camera to capture N groups of images of N subjects, the executing body may further receive a second input of the user to the N preview areas on the capture preview interface; in response to the above-described second input, the object in each of the N preview areas may be determined as the photographic object. The second input may include, but is not limited to, a sequential click input, a sequential long press input, a sequential circle selection input, a sequential frame selection input, and the like for each of the N preview regions. Therefore, the user can flexibly select the shooting object in the shooting preview interface according to the requirement.

In some optional implementations of the embodiment, after determining the object in the preview area as the shooting object, the execution subject may further mark the shooting object in the video preview interface. The marking means may include, but is not limited to, at least one of: displaying a mark frame on the photographic subject, displaying a logo beside the photographic subject, changing the style of the preview area where the photographic subject is located, and the like. As an example, fig. 2 shows a schematic diagram of a marking process of a photographic subject. The shooting preview interface comprises three shooting objects, namely a female at a close distance, a child at a medium distance, a tree and a bench at a far distance. The user may first click on a female in the vicinity, and the numeral 1 appears next to the contour of the corresponding female, identifying it as the first photographic subject. The user may continue to click on a child at a medium distance, at which time the child appears with the number 2 next to the outline, indicating that it is the second subject. Therefore, when a user selects one shooting object every time, the corresponding selection result can be displayed, the user can conveniently distinguish the selected shooting object from the unselected shooting objects, the user is prevented from repeatedly selecting or mistakenly cancelling the same shooting object, and the accuracy of user operation is improved.

It should be noted that, in this process, if the user wishes to cancel a certain photographic subject, the user may click the main body again, and then click the "change setting" control to cancel the selection of the photographic subject. The selection process of the photographic subject may be ended when the user "finishes setting" the control.

In some optional implementations of this embodiment, after the camera is controlled to capture N groups of images of N photographic subjects, N subject images may be displayed in the first area, and N background images may be displayed in the second area. The first area and the second area can be any two areas in the display interface. As an example, three photographic subjects, a female at close range, a child at medium range, and a tree at far range, are included in the photographic preview interface. After controlling the camera to capture three sets of images of the three subjects, the capture result display interface may be as shown in fig. 3. The upper area of the shooting result display interface is a first area, and an object image of a close-range female (as shown by reference numeral 301), an object image of a distant-range tree (as shown by reference numeral 302), and an object image of a medium-range child (as shown by reference numeral 303) can be displayed. The lower area of the display interface for the photographed result is a second area, which can display a background image of a close-view woman (as indicated by reference numeral 304), a background image of a distant view tree (as indicated by reference numeral 305), and a background image of a medium-view child (as indicated by reference numeral 306). By displaying the object image and the background image in different areas, the user can distinguish the object image from the background image conveniently, and convenience is provided for the user to select the target object image and the target background image in a candidate mode.

In some optional implementation manners of this embodiment, when the camera is controlled to capture N groups of images of N subjects, each subject may be focused and captured first to obtain a first intermediate image. Then, the image of the first region in the first intermediate image may be extracted to obtain an object image, and the first region may include a region surrounded by an object contour of the photographic object. Finally, a background image of each photographic subject may be obtained based on the first intermediate image or the second intermediate image. The second intermediate image may be obtained by focusing and shooting a second area, and the second area may be an image area other than the first area in the first intermediate image. The object image and the background image acquired by the method can clearly display different shot objects and different degrees of blurring effects, and provide convenience for a user to distinguish and select the shot objects required to be clearly displayed and the required blurring effects. As an example, as shown in fig. 2, the shooting preview interface includes three shooting objects, which are a close-range female, a middle-range child, and a distant-range tree. A close-up woman may be focused and photographed first, resulting in a first intermediate image of the close-up woman. Then, the area where the close-range woman is located in the first intermediate image may be used as a first area to be deducted, so as to obtain an object image (as indicated by reference numeral 301 in fig. 3) and a background image (as indicated by reference numeral 304 in fig. 3) of the close-range woman. Then, focusing and shooting can be carried out on the distant view tree, and a first middle image of the distant view tree is obtained. Then, the area where the tree is located in the first intermediate image may be used as a first area to be deducted, so as to obtain an object image (as indicated by reference numeral 304 in fig. 3) and a background image (as indicated by reference numeral 305 in fig. 3) of the distant view tree. Then, focusing and shooting can be carried out on the medium-view child, and a first intermediate image of the medium-view child is obtained. Then, the area where the child is located in the first intermediate image may be used as a first area to perform deduction, so as to obtain an object image (as indicated by reference numeral 303 in fig. 3) of the child in the middle view and a background image (as indicated by reference numeral 306 in fig. 3). By displaying the object image and the background image in different areas, the user can distinguish the object image from the background image conveniently, and convenience is provided for the user to select the target object image and the target background image in a candidate mode.

In some optional implementation manners of the present embodiment, when acquiring the background image of each photographic subject, the background image may be obtained by matting the image of the second region in the first intermediate image. For example, as shown in fig. 2, the shooting preview interface includes three shooting objects, which are a close-range female, a middle-range child, and a distant-range tree. For the first intermediate image of a close-up woman, the first region may be a region where the close-up woman is located, and the second region may be an image region other than the close-up woman. The background image may be obtained by deducting the image area outside the close-up woman. For children in the middle view and trees in the long view, the same principle is not repeated here. Therefore, background images with different blurring degrees can be obtained for different shooting objects, and a user can flexibly select the background image with the required blurring degree conveniently.

In some optional implementation manners of this embodiment, when obtaining the background image of each photographic object, focusing and photographing may be performed on the second area first to obtain a second intermediate image; then, the image of the second area in the second intermediate image can be extracted to obtain the background image. For example, as shown in fig. 2, the shooting preview interface includes three shooting objects, which are a close-range female, a middle-range child, and a distant-range tree. For the first intermediate image of a close-up woman, the first region may be a region where the close-up woman is located, and the second region may be an image region other than the close-up woman. The second intermediate image may be obtained by focusing on an area of the image other than the close-up woman (e.g., focusing on the far view). And then, deducting the image area except the close-range female in the second intermediate image to obtain a background image. For children in the middle view and trees in the long view, the same principle is not repeated here. This makes it possible to obtain a clear background image. On the basis, the blurring degree of the background image can be further adjusted, so that a user can obtain a clear background image and background images with different blurring degrees, and the blurring effect is further enriched.

Step 102, a first input of a user is received.

In this embodiment, the execution subject may receive a first input from a user. Wherein the first input is operable to select a target object image and a target background image from the N sets of images. The first input may include an input of an object image and an input of a background image in the N sets of images. The input may include, but is not limited to, a click input, a long press input, a circle selection input, a box selection input, and the like. The execution subject may take a certain object image as a target object image after detecting an input of the object image by a user. Similarly, the executing body may use the object image as the target background image after detecting the user input of a certain background image.

And 103, in response to the first input, performing image synthesis on the target object image and the target background image to generate a target blurring image.

In this embodiment, in response to the first input, the execution subject may perform image synthesis on the target object image and the target background image to generate the target blurred image. In the target blurring image, the target object image selected by the user can be displayed clearly, and other areas can be displayed in a blurring effect. When image-combining the target object image and the target background image, an image area surrounded by an object outline of the photographic object may be first extracted from the target object image. Then, the clipped region is aligned with a region surrounded by the object outline of the corresponding photographic subject in the background image. And finally, covering the deducted area in the aligned area so as to obtain the target blurring image.

In some optional implementations of the embodiment, the executing body may receive user input of at least one object image of the N object images and at least one background image of the N background images. In response to the input, the at least one object image may be first determined as a target object image and the at least one background image may be determined as a target background image.

As an example, in one shooting scene, a close-range female, a middle-range child, and a distant-range tree are included. After the camera is controlled to shoot the three groups of images of the three shot objects, an object image of a close-range female, an object image of a distant-range tree, an object image of a middle-range child, a background image of the close-range female, a background image of the distant-range tree and a background image of the middle-range child can be obtained. If the user needs to obtain an image in which the woman in the near view and the child in the middle view can be clearly displayed and the rest areas are displayed in a blurred manner, as shown in fig. 4, two photos, namely an object image of the woman in the near view (as shown by a reference numeral 401) and an object image of the child in the middle view (as shown by a reference numeral 402), can be clicked, and at this time, the edge of the photo is changed to be dark, which indicates selection, as shown in fig. 4.

Next, a background blurred picture may be selected. The degree of blurring of the background varies depending on the subject focus position. According to the optical principle, the closer the lens is to the subject, the higher the degree of background blurring. Therefore, if the user desires a high degree of blurring of the distant view, the background image of the close-up woman can be selected. If the user desires a lower or no blurring of the background, the background image of the distant view tree may be selected. Here, the user desires the background to be of a moderate blurring degree, and may select a background image of a medium-view child (as shown at reference numeral 403). On the basis, the execution main body can synthesize the images selected by the user to obtain the target blurring image with the blurring effect required by the user. In the target blurring image, a close-range woman and a middle-range child can be clearly displayed, and other areas can be blurred and displayed according to a medium blurring degree. Therefore, the user can freely select the shot object which is expected to keep clear and the area which is expected to be blurred, the selected shot object does not need to be in the same focusing plane, and the image blurring effect is enriched.

As another example, for the same shooting scene, if the user needs an image in which the woman in the close range is clearly displayed and the rest area is blurred, the user may click on the object image of the woman in the close range. Next, a background blurred picture may be selected. If the user wishes to have a high degree of blurring of the distant view, a background image of a close-up woman may be selected. If the user desires a lower or no blurring of the background, the background image of the distant view tree may be selected. If the user desires a moderate degree of blurring of the background, a background image of a medium scene child may be selected. Further, the user may select two or more background images. For example, if the user selects a background image of a close-up woman and a background image of a medium-view child, the degree of blurring may be between a high degree of blurring and a medium degree of blurring, i.e., at a high degree of blurring. On the basis, the execution main body can synthesize the images selected by the user to obtain the target blurring image with the blurring effect required by the user. In the target blurring image, a close-range female can be clearly displayed, and other areas can be blurred and displayed according to the medium-high blurring degree. Therefore, the user can freely select the shot object which is expected to keep clear and the area which is expected to be blurred, the selected shot object does not need to be in the same focusing plane, and the image blurring effect is enriched. In some optional implementation manners of this embodiment, the receiving the first input of the user may further include receiving an input of the user for a target background image in the N background images, where the input may be used to set a target blurring degree of the target background image. The input may include, but is not limited to, a click input, a double click input, a long press input, a swipe input, a custom gesture input, and the like. Thus, according to the first input, the execution subject can also determine the target blurring degree of the target background image. In the image synthesis, the target background image may be blurred according to the target blurring degree. Then, the target object image and the blurred target background image may be image-synthesized to generate a target blurred image.

As an example, the user has photographed a close-up woman as a photographic subject, and selects a subject image in the set of images as a target subject image. Then the background area is shot again, and the clear background image is selected as the target background image. At this time, as shown in fig. 5, the target object image and the target background image (as shown by reference numeral 502) may be displayed in the photographing result display interface (as shown by reference numeral 501). After the user presses the target background image for a long time, a blurring level customization interface (as indicated by reference numeral 503) may be displayed. A "background clear without blurring" control (as indicated by reference numeral 504) and a "blurring strength" control (as indicated by reference numeral 505) may be displayed in the blurring degree customization interface. In the "blurring strength" control, a slider for setting a degree of blurring may be displayed. If background blurring is not needed, the user can click the control of 'background is clear and blurring' is not needed. If background blurring is required, the user can do this by sliding the slider in the "blurring strength" control.

If the user selects the control that the background is clear and is not blurred, the blurring degree configuration information can indicate that the blurring degree is zero, blurring processing with the blurring degree being zero can be performed on the clear target background image at the moment, and the obtained blurred background image is the original clear target background image. If the user selects the control slide rail in the "blurring strength" control to be located at the center of the slide bar, the blurring degree configuration information may indicate that the blurring degree is 50%, and at this time, blurring processing of 50% of the blurring degree may be performed on the clear target background image to obtain a blurred target background image. The blurring degree of the target background image is interactively controlled by the user, so that the blurring degree of the target background image can be improved, the definition of the target background image can also be improved, the blurring effect is further enriched, and the blurring shooting flexibility is improved.

The user may input the target background image of the N background images, which may be implemented by sliding the target background image up and down, sliding the target background image left and right, or determining the blurring degree according to the sliding direction and/or distance, and the like, and is not limited to setting on the control.

In the method provided by the above embodiment of the present application, the camera is controlled to capture N groups of images of N objects, each group of images includes an object image and a background image, and then a first input of a user is received, so that in response to the first input, an image synthesis is performed on a target object image and a target background image, and a target blurred image is generated. Therefore, on one hand, under the condition that the number of the cameras is not increased, a single camera is controlled to zoom continuously to shoot a plurality of images, the generation of the virtual images is realized by combining the interactive operation of the user, and the virtual shooting cost is reduced. On the other hand, the user can flexibly select the target object and the background blurring effect which need to be clearly displayed, the selected target object is not limited by the focusing plane, the target blurring image which meets the blurring effect required by the user can be obtained, and the blurring effect of the image is enriched.
