The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, 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 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 will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. 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 provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 1, an embodiment of the present application provides a shooting method, which may specifically include the following steps:

step 11: when a dynamic picture of a target is shot, controlling a camera module to acquire N initial images; wherein N is a positive integer greater than 1.

Optionally, the N initial images may include Na initial images before photographing and Nb initial images after photographing. Before photographing, the means before receiving the input of the user to the photographing control, and after photographing, the means after receiving the input of the user to the photographing control.

For example: in the case of taking a moving picture, a storage space (buffer) for one frame may be provided for storing and managing video frame data. The buffer storing the video frame can repeatedly and covertly store the preview frame data within a period of time before the picture is taken (for example, store the preview frame data within 1.5 seconds before the picture is taken). When a photographing instruction input by a user (such as clicking input of the photographing control by the user) is received, the photo is generated. Meanwhile, the covering storage of the preview frame data in the buffer is stopped, the storage of the preview frame data is switched to the continuous storage of the preview frame data, and the preview frame data after the photographing for a certain period of time (for example, the preview frame data within 1.5 seconds after the photographing) can be continuously stored, so that N initial images can be obtained.

Step 12: performing video synthesis on the M target images to obtain a target video corresponding to the target dynamic photo; the M target images are determined according to the N initial images, and the field of view range of a video frame sequence in the target video changes according to a preset rule; m is a positive integer greater than 1, and M is less than or equal to N.

Optionally, M may be less than or equal to N, that is, this embodiment of the present application may be: m target images used for generating the target video corresponding to the target dynamic photo are determined according to part or all of the N initial images.

Optionally, the field of view range of the video frame sequence in the target video changes according to a preset rule, and the field of view range of the frame-by-frame image in the target video may increase and/or decrease regularly. For example: the field of view range of the frame-by-frame image in the target video is gradually increased, or the field of view range of the frame-by-frame image in the target video is gradually decreased, or the field of view range of the frame-by-frame image in the target video is increased after being increased, or the field of view range of the frame-by-frame image in the target video is decreased before being increased, or the field of view range of the frame-by-frame image in the target video is decreased after being increased, or the field of view range of the frame-by-frame image in the target video is decreased before being increased, or the like.

The Field of view range can be understood as the size of a Field of view (FOV), and for example, the larger the Field of view of the camera module, the larger the Field of view range of the image captured by the camera module; the smaller the angle of view, the smaller the field of view range of the captured image. Alternatively, the field range may also be understood as how much the captured image contains the picture content, for example, the larger the field range is, the more the picture content is contained; the smaller the field of view range, the less picture content it contains (if image a contains object 1 and object 2, and image B contains object 1, the larger the field of view range of image a than image B). Alternatively, the field of view range may also be understood as the ratio of the number of pixels of the target object to the total number of pixels of the image, for example, the larger the field of view range, the smaller the ratio of the number of pixels of the target object to the total number of pixels of the image; the smaller the field of view range, the larger the proportion of the number of pixels of the target object to the total number of pixels of the image.

Optionally, the video synthesizing the M target images to obtain the target video corresponding to the target moving picture may specifically include: the method comprises the steps of carrying out video coding by calling a native coder, transmitting M target images (or called frame data) into the coder, generating a target video by the coder, and establishing association between a photo and the target video in a mode of storing the generated target video in a media database. Therefore, when a photo is previewed through an album (or called as a gallery), the playing of the dynamic photo can be realized by calling the target video corresponding to the photo in the media database, and the effect of obvious dynamic change of the picture is realized when the corresponding target video is played because the field of view range of the video frame sequence in the target video changes according to the preset rule.

According to the scheme, when a dynamic picture of a target is shot, the camera module is controlled to acquire N initial images; and performing video synthesis on the M target images determined based on the N initial images to obtain a target video corresponding to the target dynamic photo. Therefore, as the field of view range of the video frame sequence in the synthesized target video changes according to the preset rule, the target video corresponding to the target dynamic photo can be displayed with obvious dynamic picture change effect when played, and the problem that the video obtained by the current dynamic photo shooting method has single display effect when played is solved.

Optionally, before the video synthesis is performed on the M target images to obtain the target video corresponding to the target dynamic photo, the method further includes:

obtaining M target images according to the N initial images; wherein, the corresponding field ranges of K1 target images in the M target images are different; k1 is a positive integer greater than 1, and K1 is equal to or less than M.

Optionally, K1 may be less than or equal to M, that is, in M target images used for generating a target video corresponding to the target dynamic photo, the field of view ranges corresponding to all or part of the target images may be different, so as to ensure that the field of view ranges of the video frame sequence in the synthesized target video change according to a preset rule, so that when the target video of the dynamic photo is played, an effect of obvious dynamic change of the picture may be presented.

Specifically, the field of view range corresponding to each of the M target images is different; or, the corresponding field ranges of the M target images are different for every a target images, for example: m is 9, A is 3, for example, the field of view ranges corresponding to the 1 st to 3 rd target images are the same, the field of view ranges corresponding to the 4 th to 6 th target images are the same, the field of view ranges corresponding to the 7 th to 9 th target images are the same, the field of view ranges corresponding to the 1 st to 3 th target images are different from the field of view ranges corresponding to the 4 th to 6 th target images, and the field of view ranges corresponding to the 4 th to 6 th target images are different from the field of view ranges corresponding to the 7 th to 9 th target images; the field of view range corresponding to the 1 st to 3 rd target images and the field of view range corresponding to the 7 th to 9 th target images may be the same or different, and the embodiment of the application is not limited thereto.

Optionally, the obtaining M target images according to the N initial images includes:

respectively performing cropping processing on the K2 initial images to obtain K2 first intermediate images, namely respectively performing cropping processing on each initial image in the K2 initial images to obtain K2 first intermediate images; wherein K2 is a positive integer, and K2 is not more than N;

carrying out scaling processing on each first intermediate image to obtain K2 second intermediate images; wherein the K2 second intermediate images are the same size;

obtaining the M target images according to the K2 second intermediate images; or obtaining the M target images according to K2 second intermediate images and the N initial images.

As an implementation, determining the M target images according to the K2 second intermediate images may include: if K2 is equal to M, the K2 second intermediate images are determined as the M target images.

For example: m may be less than or equal to N, that is, all or part of the N initial images may be selected, and the cropping processing and the scaling processing may be performed on each selected initial image, respectively, to obtain K2 second intermediate images, and determine the K2 second intermediate images as the M target images.

As another implementation, determining the M target images according to the K2 second intermediate images may include: if K2 > M, determining M second intermediate images of the K2 second intermediate images as the M target images.

For example: k2 may be less than or equal to M, that is, all or part of the N initial images may be selected, and cropping processing and scaling processing may be performed on each selected initial image, resulting in K2 second intermediate images; and M may be less than or equal to K2, i.e., M second intermediate images may be selected from the K2 second intermediate images and determined as the M target images.

As still another implementation, determining the M target images according to the K2 second intermediate images and the N initial images may include: if K2 < M, determining K3 initial images of the K2 second intermediate images and the N initial images as the M target images; wherein, K2+ K3 is M.

Where the K2 second intermediate images are obtained after the cropping and enlarging process, the K3 initial images may be K initial images that are sequentially taken before the K2 second intermediate images from among the N initial images; for example: when K3 is 1, the first initial image of the N initial images arranged in the shooting order is not subjected to the cropping and scaling processing, and K2 initial images of the N initial images are subjected to the cropping processing and the scaling processing, respectively, to obtain K2 second intermediate images, and the first initial image and the K2 second intermediate images are determined as the M target images.

Optionally, the performing a cropping process on the K2 initial images respectively to obtain K2 first intermediate images includes:

cutting off the edge area of the initial images according to the target scale for K2 initial images to obtain K2 first intermediate images, namely cutting off the edge area of the initial images according to the target scale for each of K2 initial images to obtain K2 first intermediate images;

and in the K2 initial images, the corresponding target proportion is different when at least part of the initial images are cut.

For example: the target proportion may be gradually increased, or the target proportion may be gradually decreased, or the target proportion may be increased and then decreased, or the target proportion may be decreased and then increased, or the target proportion may be increased and then decreased in the shooting order of K2 initial images, or the target proportion may be increased and decreased at intervals according to a predetermined rule, and the like, and the embodiment of the present application is not limited to this.

Specifically, when the initial image obtained by shooting is stored in the buffer, the initial image (or referred to as frame data) in the buffer can be taken out frame by frame and cut; the cutting rule may be to cut off an edge area (or called a frame) of the target proportion according to the original aspect ratio by using a central point of the original initial image as a fixed central point, to obtain new data (i.e., a first intermediate image) with the frame removed, and to perform an amplification process after cutting frame by frame according to the rule that the target proportion is gradually increased, to obtain second intermediate images, so that all the second intermediate images have the same size, and thus in the second intermediate images arranged according to the shooting sequence, the field of view is gradually reduced, that is, the finally synthesized target video may exhibit an effect of gradually amplifying the target object, thereby improving a dynamic display effect of the target video of the dynamic photo when being played.

Optionally, the method further comprises:

before M target images are obtained according to the N initial images, obtaining the movement parameters of the camera module; or acquiring the movement parameters of the camera device; wherein, the camera shooting module is arranged on the camera shooting device.

When the motion parameter meets a preset condition, that is, when the motion parameter is greater than a preset threshold (that is, the motion range of the camera module/camera device is large), the step of obtaining M target images according to the N initial images may not be performed, and video synthesis may be directly performed according to part or all of the N initial images to obtain a target video corresponding to the target dynamic photo.

When the motion parameter does not meet a preset condition, that is, when the motion parameter is less than or equal to a preset threshold (that is, the motion range of the camera module/camera device is small), the specific steps of obtaining M target images according to the N initial images can be executed, so as to ensure that the motion range of the camera module/camera device is small, that is, the change of the field of view range of the N initial images is small, and the target video corresponding to the target dynamic photo can be obviously dynamically displayed during playing through the scheme.

Optionally, the controlling the camera to acquire N initial images includes:

controlling at least two camera modules to respectively acquire at least two groups of initial images; wherein, a camera module gathers and obtains a set of initial image. Namely, each camera module in the at least two camera modules is controlled to respectively acquire a group of initial images; the number of a group of initial images acquired by different camera modules can be the same or different, and the group of initial images comprises at least one initial image;

obtaining the N initial images based on the at least two groups of initial images; for example: the initial images shot by all the camera modules can be determined as the N initial images; wherein, the field angles of different camera modules are different.

Among the at least two camera modules, the different camera modules have different corresponding field angles, so that the different camera modules have different corresponding field ranges of initial images. For example: at least two modules of making a video recording can be the module of making a video recording that has wide-angle camera, main module of making a video recording and the module of making a video recording that has long focus camera, and wherein the angle of vision that the main module of making a video recording corresponds can be between the angle of vision of the module of making a video recording that should have wide-angle camera and the angle of vision of the module of making a video recording that should have long focus camera, and this application embodiment of course does not use this as the limit.

For example: when a dynamic photo is taken, three frames of storage spaces (buffers) can be set, and the three buffers are respectively used for storing and managing initial images (or frame data) taken by the three camera modules. Frame data of a period of time before photographing (such as data of 1.5 second frames before each photographing) is read from the camera module with the wide-angle camera, the main camera module and the camera module with the long-focus camera and stored in respective buffers in an overlaying manner. After receiving a photographing instruction input by a user, generating a dynamic photo; and stopping the mode of covering and storing the frame data in the three buffers, switching to continuously storing the frame data, and continuously storing the frame data of a period of time after the photographing (such as the frame data of 1.5 seconds after the photographing) into the respective buffers aiming at the camera module with the wide-angle camera, the main camera module and the camera module with the long-focus camera, so as to obtain a group of initial images which are respectively photographed by each camera module.

and respectively acquiring partial initial images from each group of initial images to obtain the M target images. Namely, respectively acquiring partial initial images from a group of initial images shot by each camera module; determining all of the acquired initial images as the M target images.

Wherein all of the obtained initial images are: and partial initial images are respectively acquired from a group of initial images shot by each camera module.

In this embodiment, because the field of view ranges corresponding to the initial images captured by the different camera modules are different, when a target video corresponding to the target dynamic photo is obtained by further selecting a part of the initial images captured by the different camera modules to perform video synthesis, the target video can exhibit an effect of obviously changing the field of view range dynamically during playing, and thus the dynamic display effect of the target video of the dynamic photo during playing can be improved.

Optionally, the obtaining of the partial initial images from each group of the initial images respectively includes:

and respectively acquiring partial initial images in different shooting time periods from each group of initial images, namely acquiring partial initial images corresponding to different shooting time periods from a group of initial images shot by different camera modules.

Specifically, selecting partial initial images corresponding to different shooting time periods from a group of initial images shot by different camera modules can be understood as follows: selecting a part of initial images corresponding to a first shooting time period from a group of initial images shot by a first target camera module aiming at any two camera modules (such as a first target camera module and a second target camera module) in at least two camera modules; selecting a part of initial images corresponding to a second shooting time period from a group of initial images shot by the second target camera module; the first shooting time period is different from the second shooting time period, for example, the shooting time periods corresponding to different camera modules may also be determined according to an increasing or decreasing order of the field angles corresponding to different camera modules, which is not limited in this embodiment of the present application.

Optionally, the method further comprises:

When the motion parameter does not meet a preset condition, that is, when the motion parameter is less than or equal to a preset threshold (that is, the motion range of the camera module/camera device is small), the specific steps of obtaining M target images according to the N initial images may be performed, so as to ensure that the motion range of the camera module/camera device is small, that is, the change of the field of view range of the N initial images is small, and the dynamic display effect of the target video corresponding to the target dynamic photo during playing may be improved by the above-mentioned scheme.

and under the condition that the movement parameters meet preset conditions, acquiring M initial images from a group of initial images acquired by a first camera module to obtain M target images. Under the condition that the movement parameter is larger than a preset threshold, acquiring M initial images from a group of initial images acquired by a first camera module; determining the M initial images as the M target images; wherein, the first module of making a video recording is one in the at least two modules of making a video recording.

For example: the at least two camera modules can be a camera module with a wide-angle camera, a main camera module and a camera module with a long-focus camera, wherein the angle of view corresponding to the main camera module can be between the angle of view of the camera module with the wide-angle camera and the angle of view of the camera module with the long-focus camera, and the first camera module can be the main camera module.

Therefore, under the condition that the movement parameter is larger than the preset threshold (namely, the movement range of the camera module/the camera device is larger), the video synthesis can be directly carried out according to the initial image shot by the main camera module to obtain the video image of the shot dynamic photo, so that the movement range of the camera module/the camera device is larger, namely, the change of the field range of the N initial images is larger, the obvious dynamic display effect of the target video corresponding to the target dynamic photo can be ensured while the image quality of the target video is ensured when the target video is played.

The following describes the shooting method of the present application with reference to specific examples:

as shown in fig. 2, a flowchart of a shooting method is provided, which specifically includes:

step 201: and entering a dynamic photo shooting mode.

Step 202: upon entering the dynamic photo shooting mode, a frame storage space (buffer) may be set, and this buffer is used to store and manage video frame data.

Step 203: the buffer storing the video frame data repeatedly and coveringly stores the preview frame data within 1.5 seconds before the photographing.

Step 204: as shown in fig. 3, the photo control 31 is clicked to generate a photo.

Step 205: and stopping storing the preview frame data in the buffer in an overlaying mode while generating the picture, and replacing the preview frame data in a continuous mode.

Step 206: and generating a photo and judging whether a function menu of the dynamic effect is opened or not. The "dynamic effect" function is an effect that the field range of the video frame sequence in the video corresponding to the dynamic photo changes according to a preset rule.

Step 207: when the function of 'dynamic effect' is started, whether the mobile phone moves within 1.5 seconds before and after the photographing is continuously judged (certain error can be set at the moving position). If the mobile phone is mobile, directly executing step 210; if the handset is not mobile, step 208 is performed.

Step 208: frame data in the buffer are taken out frame by frame for cutting, and the cutting rule is that a frame (namely an edge area) with a preset proportion is cut frame by taking the central point of initial frame data as a fixed central point according to the width-height ratio of the initial frame data, so as to obtain new frame data with the frame removed. When frames with preset proportion are cut off frame by frame, the preset proportion is increased frame by frame, and thus the range of each frame of data in the obtained new frame of data is smaller than that of the previous frame of data.

Step 209: and taking out the frame data in the buffer frame by frame, calling an amplification algorithm, and amplifying the cut frame data to the width and height of the initial frame data, so that the video generated based on the cut and amplified frame data can be presented as the effect that the target object is gradually amplified visually during playing.

Step 210: and after the processed frame data are obtained, calling a native encoder to perform video encoding, and transmitting the frame data into the encoder.

Step 211: after the encoder generates the video, the photo and the video are associated in a mode of storing a media database, so that the video corresponding to the photo can be found through the media database when the video is played in the gallery.

According to the embodiment of the invention, by means of cutting frame data and amplifying the cut frame data to the width and height of the initial frame data, the effect that the field range corresponding to the frame-by-frame data changes from small to large (such as the constant small to large change similar to zoom) is achieved, so that the effect of continuously amplifying the pictures can be presented when the video corresponding to the dynamic photo is played, and the problem that the display effect of the video obtained by the current shooting method of the dynamic photo is relatively single when the video is played is solved.

As shown in fig. 4, a flowchart of another shooting method is provided, which specifically includes:

step 401: and entering a dynamic photo shooting mode.

Step 402: after entering the dynamic picture shooting mode, three frame storage spaces (buffers) are set, and the three buffers are used for respectively storing and managing frame data of three cameras.

Step 403: when entering a dynamic photo shooting mode, a wide-angle camera, a main shooting camera and a Tele camera are opened.

Step 404: the data frame of 1.5 seconds is read from the frame data shot by the wide-angle camera, the main camera and the Tele camera respectively, and is stored in the buffer in an overlaying manner.

Step 405: as shown in fig. 3, the photo control 31 is clicked to generate a photo.

Step 406: and stopping three cameras to store frame data in respective buffers in an overlaying mode while generating the pictures, and continuously storing the frame data of 1.5 seconds shot by the wide-angle, main shooting and Tele cameras into the respective buffers instead of continuously storing the frame data.

Step 407: and judging whether the function menu of the dynamic effect is opened or not.

Step 408: and when the function menu of the dynamic effect is not started, transmitting the frame data in the main shooting buffer into a video encoder for encoding.

Step 409: and when the function menu of the dynamic effect is opened, judging whether the mobile phone moves. When the mobile phone is judged to move (a certain error can be set), step 408 is executed; when the mobile phone is not moved, step 410 is executed.

Step 410: reading the frame data of the previous second from the wide-angle buffer, reading the frame data of the middle second from the main shooting buffer, and reading the frame data of the last second from the Tele buffer to form a new buffer.

Step 411: and transmitting the frame data in the composed new buffer into a video encoder for encoding.

Step 412: after the encoder generates the video, the photo and the video are associated in a mode of storing a media database, so that the video corresponding to the photo can be found through the media database when the video is played in the gallery.

According to the embodiment of the application, the wide-angle camera, the main shooting camera and the long-focus camera are opened, one second of video frame data is taken from the three cameras respectively to form a 3-second video, so that the effect that the FOV changes from large to small can be presented when the video of the dynamic photo is played, the effects that the FOV changes and the picture is enlarged when the video in the dynamic photo is played are achieved, and the problem that the video obtained by the current shooting method of the dynamic photo is single in display effect when the video is played is solved.
