Fig. 1 is a flowchart illustrating a method for generating a short video according to an exemplary embodiment, where the method is applied to an electronic device, as shown in fig. 1, and may include the following steps:
in step 102, a photographing instruction for an electronic device is received.
In step 104, when the dynamic photo capturing function of the electronic device is in an on state, a dynamic photo generated by the electronic device in response to the photographing instruction is acquired.
In one embodiment, when the dynamic photo collection function of the electronic device is in a closed state, the electronic device takes a photo for a received photographing instruction; when the dynamic photo collection function of the electronic device is in an open state, the electronic device obtains a dynamic photo for the received photographing instruction, and the dynamic photo comprises a plurality of image frames and can be regarded as a video with short duration (namely, a short video).
In one embodiment, when the electronic device generates a dynamic photo, one image frame of the dynamic photo (typically, the image frame acquired at the time when the photo instruction is received) may be set as a static cover image, so that when the user performs a first trigger operation (e.g., opening an album) on the dynamic photo, the static cover image can be viewed, which is similar to viewing a normal photo, and when the user performs a second trigger operation (e.g., pressing or pressing the static cover image for a long time) on the dynamic photo, the dynamic photo can be played, which is equivalent to playing a video with a short time to the user. Therefore, the motion picture has the motion information recording characteristic of video and the still information recording characteristic of the picture, and is different from the normal video.
In step 106, an editing operation is performed on at least one image frame used to construct the moving picture according to the received user editing instruction.
In one embodiment, each image frame of a dynamic photo may only implement intra-frame compression, enabling the electronic device to provide any image frame of the dynamic photo to a user for the user to implement an editing operation. In other embodiments, the image frames of the dynamic photo may implement inter-frame compression (only inter-frame compression, or both intra-frame compression and inter-frame compression), and the electronic device may still provide at least one image frame of the dynamic photo to the user for the user to perform an editing operation.
In one embodiment, the image frames used to construct the motion picture comprise: the electronic equipment responds to the photographing instruction to implement at least one photo obtained by photographing operation, at least one photo collected by the electronic equipment before the photographing operation is implemented, and at least one photo collected by the electronic equipment after the photographing operation. Compared with the common video shooting, the dynamic photo or the short video disclosed by the invention is simple to operate (a user only needs to send a shooting instruction), easy to manufacture, easy to transmit and share due to less data, capable of improving the playing will of the user and beneficial to improving the information sharing efficiency. However, since the shooting time of a moving picture or a short video is short (usually tens of seconds or several seconds), it is often difficult to capture an emergency except for a panning scene, and although the above problems exist in a normal video, the problem can be compensated by long-time continuous shooting and post-editing; and the dynamic photo comprises at least one photo obtained by the electronic equipment performing the photographing operation in response to the photographing instruction, namely the electronic equipment automatically performs the photographing operation before receiving the photographing instruction, so that the user can issue the photographing instruction after finding an emergency, still can capture the emergency in the dynamic photo, and does not need to continuously take a picture for a long time and clip a later period.
In step 108, the edited at least one image frame and other image frames used for forming the dynamic photo are synthesized into a short video.
In one embodiment, the short video may be in the same file format as the dynamic photo, so that the user uses the short video in a similar way to the dynamic photo, such as setting one image frame for constituting the dynamic photo as a static cover image of the short video, presenting the static cover image when a first trigger operation for the short video is detected, and playing the short video when a second trigger operation for the short video is detected. In other embodiments, the short video may be in a different file format than the motion picture, which is not limited by this disclosure.
In an embodiment, an operation object of the editing operation may be independent of a subject in the at least one image frame, for example, the operation object may include a decorative pattern added to the image frame, and the electronic device may automatically perform the editing operation on other image frames used for composing the moving picture, so that the obtained image frames are used for composing the short video. By the embodiment, the editing operation carried out by the user in the partial image frame can be applied to all the image frames, so that the corresponding editing effect can be presented in the whole short video without carrying out the editing operation by the user one by one, and the user operation is facilitated to be simplified. In other embodiments, the corresponding editing effect may be presented only in the image frame in which the user performs the editing operation, and the editing operation may not be automatically performed in other image frames.
In an embodiment, the operation object of the editing operation may be a subject in the at least one image frame, for example, the subject may include a shooting subject, a shooting background, and the like, which is not limited by the present disclosure. By determining the image frame including the subject among the other image frames used to construct the moving picture, the electronic device can automatically perform the editing operation on the determined image frame including the subject, so that the resulting image frame is used to synthesize the short video. By the embodiment, the editing operation carried out by the user in the partial image frame can be applied to all the image frames, so that the corresponding editing effect can be presented in the whole short video without carrying out the editing operation by the user one by one, and the user operation is facilitated to be simplified. For example, if a user performs portrait beautification on a subject person in one image frame, automatic portrait beautification can be performed on the subject person in any of the other image frames.
In one embodiment, an audio capture operation may be performed during the capture of the image frames used to construct the motion picture by the electronic device; then, the edited image frame, other image frames used for forming the dynamic photo and the collected audio are synthesized into a short video, so that the short video has better information expression capability.
According to the embodiment, the dynamic photo is obtained when the user takes a picture, the editing function aiming at the image frames forming the dynamic photo is provided for the user, so that the user can conveniently and rapidly implement the editing operation aiming at the image frames forming the dynamic photo, the edited image frames are combined into the short video, and the short video is rapidly generated on the electronic equipment.
Fig. 2 is a flowchart illustrating another short video generation method according to an exemplary embodiment, and as shown in fig. 2, the method applied to an electronic device may include the following steps:
in step 202, a camera application is started on the electronic device.
In an embodiment, the camera application may provide a switch option of the dynamic photo taking function to the user, and when it is detected that the dynamic photo taking function is in an off state, the electronic device may implement a normal photographing operation when it is detected that the taking option is triggered, so as to implement taking of a single photo or continuous taking of multiple photos. When the dynamic photo shooting function is detected to be in the open state, the electronic equipment can realize the shooting operation of the dynamic photo, and further realize the technical scheme of the disclosure.
In step 204A, the electronic device automatically cycles through image frames in the event that the motion picture taking function has been turned on.
In one embodiment, when the dynamic photo shooting function is turned on, if a camera application of the electronic device is turned on, the camera application may automatically and continuously capture image frames without receiving a shooting instruction issued by a user. In order to avoid occupying too many resources, the image frames acquired by the camera application may be limited within a specific duration, for example, the specific duration may be 1s, and if a photographing instruction is still not detected after 1s, the camera application continues to acquire new image frames and deletes the previously acquired image frames in the acquisition order, so that the image frames remaining in the electronic device do not exceed 1s all the time.
In step 204B, the electronic device detects that the photo option is triggered.
In an embodiment, the camera application may provide a photographing option to the user, and the photographing option is consistent when the dynamic photo photographing function is turned on and off, so that it is ensured that the user experiences in the two scenes are consistent, and the learning threshold of the user may be reduced.
In step 206, the dynamic photograph is composed.
In an embodiment, the camera application may acquire the image frame acquired before the photographing option is triggered and with a specific duration, the image frame acquired when the photographing option is triggered and the image frame acquired after the photographing option is triggered and with a specific duration, and jointly synthesize the image frames into the dynamic photo.
In one embodiment, during the process of synthesizing a dynamic photo, intra-frame compression and/or inter-frame compression may be applied to the image frames to reduce the storage footprint of the dynamic photo. For example, the dynamic photos may adopt a Motion JPEG (MJPEG, Motion Joint Photographic Experts Group, fountain cc: MJPEG) format, wherein each image frame is JPEG-encoded, and only intra-frame compression is performed on the image frame, so that in the process of synthesizing and editing the dynamic photos, encoding and decoding operations can be implemented based on fewer processing resources, which is helpful for increasing the synthesis speed of the dynamic photos (so that a user can hardly perceive the synthesis process, the synthesis process of the dynamic photos approaches to the shooting process of common photos, and is helpful for optimizing the application experience of the user), and smoothly implementing the editing operation of the dynamic photos.
In step 208, it is determined whether the user needs to edit the dynamic photo; when editing is required, proceed to step 210.
In an embodiment, the processing may be performed based on other sequences besides the processing manner of step 206 and step 210 shown in fig. 2. For example, a camera application may acquire image frames for composing a dynamic photograph and first ask the user whether the dynamic photograph needs to be edited; when the user does not need to edit the dynamic photos, the camera application can synthesize the dynamic photos by using the image frames, and when the user needs to edit the dynamic photos, the camera application can show the image frames to the user so as to implement editing operation by the user.
In step 210, the image frames that make up the motion picture are presented.
In one embodiment, the displayed image frames may be image frames acquired by a camera application, i.e., the image frames are not compressed. In another embodiment, the displayed image frame may be an extracted image frame in a dynamic picture, and the image frame may be subjected to a corresponding compression process, such as intra-frame compression or inter-frame compression.
In an embodiment, the image frames may be arranged and displayed according to a time sequence, so that a user may select an image frame that needs to perform an editing operation.
In step 212, the selected image frame is edited according to the detected user editing instruction.
In one embodiment, a user may select one or more image frames and perform an editing operation on the image frames. In one case, the editing object of the editing operation may include a subject in an image frame, such as a subject, a background, etc. in one dimension, and a person, an animal, a plant, a building, a natural landscape, etc. in another dimension, and the editing operation may be performed on one or more subjects, such as beautifying a subject person, blurring a background, etc., which is not limited by the present disclosure. In another case, the editing object of the editing operation may be independent of the subject in the image frame, for example, the user may add a filter, adjust a color tone, add a virtual illumination light source, and the like to the entire image frame, and for example, the user may add a decorative pattern, a decorative text, and the like to the image frame.
In an embodiment, in order to facilitate the user to perform the editing operation, a preprocessing operation may be performed on the image frame, for example, the electronic device may actively identify a subject included in the image frame, and may also mark the subject, thereby improving the efficiency of the user performing the editing operation on the subject.
In step 214, it is determined whether an editing operation needs to be applied to all image frames; when it is determined that the application is needed, the process proceeds to step 216, and when it is determined that the application is not needed, the process proceeds to step 218.
In step 216, the remaining image frames are automatically edited.
In an embodiment, the user may perform an editing operation only for a part of the image frames, and if the user wishes to apply an editing effect to all the image frames constituting the moving picture, the user may select to automatically edit the remaining image frames, and the electronic device may automatically perform the same or corresponding editing operations on the remaining image frames according to the editing operation performed by the user, without the user performing the editing operation for all the image frames one by one.
For example, the user may perform beautification processing on the subject person in one image frame, and when the user selects to automatically edit the remaining image frames, the electronic device may determine the same subject person in the remaining unprocessed image frames and perform the same beautification processing on the subject person, thereby ensuring that the subject person is subjected to the same or similar beautification processing in all image frames.
For another example, the user may add a decoration pattern at a certain position in one image frame, and when the user selects to automatically edit the remaining image frames, the electronic device may add the decoration pattern at the same position in the other unprocessed remaining image frames, thereby ensuring that the decoration pattern is displayed at the same position in all image frames.
For another example, the user may add a decoration pattern at a first position of a first image frame and a decoration pattern at a second position of a last image frame, and when the user selects to automatically edit the remaining image frames, the electronic device may add the decoration pattern at corresponding positions in the remaining unprocessed image frames, thereby ensuring that the decoration pattern is displayed in all the image frames, and the positions of the decoration patterns in the respective image frames are sequentially changed, presenting a visual change effect that the decoration pattern gradually moves from the first position to the second position.
In step 218, the image frames are synthesized into a short video.
In one embodiment, if the editing operation is not applied to all image frames, the image frames edited by the user and the unedited remaining image frames can be synthesized to obtain a short video; if the editing operation is applied to all image frames, all edited image frames can be synthesized to obtain a short video.
In one embodiment, the file format of the short video may be the same as the dynamic photo, which may be understood as replacing the dynamic photo with the edited short video. The image frame collected when the photographing option is triggered can be set as the static cover image of the short video, so that the user can see the static cover image when normally viewing the album, and the corresponding short video can be played when the user presses or re-presses the static cover image for a long time.
In an embodiment, the file format of the short video may be different from that of the motion picture, for example, MP4 format, GIF format, etc. are adopted, so that the short video can be transmitted, shared, and played normally on various electronic devices.
