Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. 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.
At present, a processing scheme for a dynamic picture is only to process a first frame of the dynamic picture, so that the dynamic picture is changed into a static picture after being processed, because the dynamic picture compresses the same pixels of multiple frames of pictures in order to reduce the picture storage volume, after the dynamic picture is subjected to frame splitting, except for a first frame of picture, the information of other frames of pictures is incomplete, and if the pictures are processed frame by frame, errors can occur. Therefore, the dynamic picture processing scheme is provided, and the information integrity of each frame of picture can be guaranteed, so that errors are avoided during frame-by-frame processing, and the processed picture is guaranteed to keep the animation effect of the original picture.
Referring to fig. 1, an embodiment of the present application discloses a method for processing a dynamic picture, including:
step S11: obtaining a transparent picture;
and all the pixels in the transparent picture are transparent pixels. The size of the transparent picture is consistent with the picture size of the dynamic picture to be processed.
Step S12: and respectively carrying out synthesis operation on the non-first frame picture of the dynamic picture to be processed and the transparent picture to obtain a corresponding target dynamic picture.
In an embodiment, if the to-be-processed dynamic picture is a dynamic picture, the non-first frame picture of the dynamic picture is respectively synthesized with the transparent picture to obtain a corresponding target dynamic picture.
In another embodiment, if the to-be-processed dynamic picture includes multiple dynamic pictures, the non-first-frame picture of each dynamic picture is synthesized with the transparent picture to obtain a target dynamic picture corresponding to each dynamic picture. That is, a plurality of target moving pictures are obtained, wherein the plurality is greater than or equal to two.
And firstly, the dynamic picture is subjected to frame removal processing, and then the non-first frame picture and the transparent picture are respectively subjected to synthesis operation to obtain a corresponding target dynamic picture.
It should be noted that, in order to reduce the picture storage volume, the dynamic picture compresses the same pixels of multiple frames of pictures, so that after the dynamic picture is subjected to frame removal, it cannot be guaranteed that the picture size of each frame is the same, in order to make the picture size of each frame the same for subsequent picture processing, the application adopts a transparent picture with a preset size to perform synthesis operation with a non-first frame of picture, in order to reduce the picture storage volume, the dynamic pictures such as GIF, APNG and the like adopt a pixel compression algorithm in the multi-frame picture synthesis, the algorithm is realized by the dynamic picture itself, and the transparent pixels are only filled into the default part of the picture, so that the picture size of each frame is kept consistent. The preset size is the same as the size of the dynamic picture to be processed.
Step S13: and presetting the target dynamic picture frame by frame.
In one embodiment, the target dynamic picture is scaled frame by frame. For example, referring to fig. 2, fig. 2 is a schematic diagram of a specific dynamic image scaling process disclosed in the embodiment of the present application, a dynamic image with a size of 300 × 300 and a total of 30 frames is first split into frames, the frames are synthesized with a transparent image with a size of 300 × 300 frame by frame from the 2 nd frame, then the frames are reduced to 100 × 100 frames, and finally a dynamic image with 100 × 100 and a total of 30 frames is obtained.
In another embodiment, if the to-be-processed moving picture includes a plurality of moving pictures, the target moving pictures corresponding to the plurality of moving pictures are synthesized frame by frame.
For example, as shown in fig. 3, fig. 3 is a schematic diagram of a dynamic picture synthesis process disclosed in the embodiment of the present application, two dynamic pictures of 30 frames are first synthesized with a transparent picture, respectively, where the size of the transparent picture is consistent with that of the original dynamic picture, specifically, a non-first frame picture of each dynamic picture is synthesized with the transparent picture, and then the two dynamic pictures are synthesized frame by frame to obtain a synthesized dynamic picture.
In one embodiment, a dynamic picture to be zoomed may be determined from a plurality of the target dynamic pictures; the dynamic pictures to be zoomed are one or more dynamic pictures in the plurality of target dynamic pictures; and zooming the dynamic picture to be zoomed frame by frame to a target size.
For example, referring to fig. 4, fig. 4 is a schematic diagram illustrating a composite of two specific target motion pictures disclosed in the embodiment of the present application, where the two target motion pictures have a size of 200 × 200 and a size of 500 × 250, and the picture of 500 × 250 is processed to be 500 × 200, so as to make the two target motion pictures more beautiful after being spliced.
In one embodiment, if the sizes of the plurality of target dynamic pictures are not consistent, a standard dynamic picture is determined from the plurality of target dynamic pictures, and the pixel coordinates of a frame picture corresponding to each frame picture in the non-standard dynamic picture are determined based on the pixel coordinates of each frame picture in the standard dynamic picture, so as to obtain the composite coordinates of each frame picture in the non-standard dynamic picture; and carrying out frame-by-frame synthesis processing on the non-standard dynamic picture and the standard dynamic picture based on the synthesis coordinates. For example, the number of the first target dynamic picture is two, the last row of pixels of the first frame picture in the first target dynamic picture are (x 1, y 1), (x 1, y 2) and (x 1, y 3) \8230, the composite coordinates of the first row of the second target dynamic picture are (x 1+ n, y 1), (x 1+ n, y 2) and (x 1+ n, y 3) \8230, and n is the horizontal coordinate distance between two pixel points.
Further, in an embodiment, if the number of frames of the plurality of dynamic pictures is not consistent, performing frame extraction on the first dynamic picture to obtain a dynamic picture with the number of frames consistent with that of the second dynamic picture; the first dynamic picture is a dynamic picture with the lowest non-frame number in the plurality of dynamic pictures, and the second dynamic picture is a dynamic picture with the lowest frame number in the plurality of dynamic pictures.
That is, a plurality of dynamic pictures can be processed into dynamic pictures with consistent frame number between the synthesis operations of the non-first frame picture of the dynamic picture to be processed and the transparent picture.
In one embodiment, if the playing delays of the plurality of dynamic pictures are inconsistent, the playing delay of the first dynamic picture is modified according to the playing delay of the second dynamic picture; the first dynamic picture is a dynamic picture with the lowest non-frame number in the plurality of dynamic pictures, and the second dynamic picture is a dynamic picture with the lowest frame number in the plurality of dynamic pictures. In addition, before the playing delay of the first dynamic picture is modified according to the playing delay of the second dynamic picture, frame extraction operation is carried out on the second dynamic picture, so that the frame number of the second dynamic picture is consistent with that of the first dynamic picture.
It can be understood that the playing delay, i.e., the time interval between two frames of pictures, needs to be processed to be consistent before the composition, for example, if the playing delay of a dynamic picture with a lower frame number in two dynamic pictures is 0.2s, and the playing delay of a dynamic picture with a higher frame number is 0.1s, the frame of the dynamic picture with a higher frame number is extracted first, and then the playing delay is processed to be 0.2s. For example, the playing delay of one motion picture is 0.2 for 25 frames, the playing delay of the other motion picture is 0.1 for 30 frames, the frames of the motion pictures of 30 frames are first extracted into 25 frames, and then the playing delay is processed into 0.2s.
As can be seen, in the embodiment of the present application, a transparent picture is obtained first, then a non-first frame picture of a to-be-processed dynamic picture is synthesized with the transparent picture, respectively, to obtain a corresponding target dynamic picture, and finally, the target dynamic picture is subjected to frame-by-frame preset processing. That is, in the embodiment of the present application, before performing the preset processing frame by frame on the dynamic picture, the non-first frame picture is synthesized with the transparent picture, so that the information integrity of each frame of picture can be ensured, thereby avoiding an error occurring during the frame by frame processing, and ensuring that the processed picture retains the animation effect of the original picture.

That is, in the embodiment of the present application, before performing the preset processing frame by frame on the dynamic picture, the non-first frame picture is synthesized with the transparent picture, so that the integrity of the information of each frame picture can be ensured, thereby avoiding the occurrence of errors during the frame by frame processing, and ensuring that the processed picture retains the animation effect of the original picture.
