[0002] With the development of the Internet, the application of animated images in mobile applications and front-end web pages has become increasingly widespread, bringing a richer and more diverse visual experience to users.

[0003] However, the production of animated images often stems from video transcoding and synthesis, which inevitably leads to the problem of large animated image file sizes. Although current image formats such as webp provide methods of lossy compression and lossless compression to reduce file sizes, due to the high frame rate characteristics of animated images, their file sizes still remain at a relatively high level. In addition, excessive lossy compression will also reduce the clarity of the image, thus damaging the user experience.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0059] For ease of understanding of the embodiments of the present invention, the following will further explain and illustrate with specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0060] The embodiments of the present invention provide a method for generating a moving picture. Refer to Figure 1 , Figure 1 which is a flowchart of an embodiment of a method for generating a moving picture provided by the embodiments of the present invention. Figure 1 The process shown may include the following steps:

[0061] Step 101, obtain a target picture and generate a first moving picture based on the target picture;

[0062] In practical applications, this method is applied to a moving picture generation system, which provides a moving picture generation interface to facilitate users to upload the target picture required for generating a moving picture to the moving picture generation system through the moving picture generation interface according to actual needs, so as to generate a first moving picture with a high frame rate.

[0063] For ease of understanding, as Figure 2 shown is the moving picture generation interface. The target picture uploaded by the user is shown in the left partition of the moving picture generation interface, and the special effects set for generating the first moving picture corresponding to the target picture are shown in the right area of the moving picture generation interface. In this embodiment, without the need for design software and complex operations, the user can directly generate a high-quality and high-frame-rate first moving picture by selecting special effects on the moving picture generation interface. Compared with the traditional moving picture production that requires professional design software and a long production cycle, this moving picture production method can greatly reduce the manual design cost, reduce the dependence on designers and developers, and significantly shorten the time from the planning to the launch of the operation activity, improving the activity execution efficiency. The specific process of generating the first moving picture using the moving picture generation interface will be specifically described in the following embodiments and will not be elaborated here.

[0064] Step 102, perform frame splitting on the first moving picture to obtain a frame sequence;

[0065] In practical applications, for ease of subsequent compression and frame extraction processing of the first moving picture, it is necessary to perform frame splitting on the first moving picture. Among them, step 102 can be implemented through steps A1 to A3:

[0066] Step A1: Obtain the current animation frame of the first animated image based on the animation play state property.

[0067] The animation play state property (animation-play-state) is an important property in CSS (Cascading Style Sheets) animations. It is used to control the play state of the animation. Specifically, this property has two values: running and paused. When the animation play state property is set to running, the animation will start or continue to play; when the animation play state property is set to paused, the animation will pause. In this embodiment, the animation play state property is set to paused. Since the first animated image has been paused, the currently displayed animation frame is the current animation frame to be obtained.

[0068] Step A2: Use a preset static rendering method to statically render the current animation frame to obtain a frame-divided image.

[0069] In specific implementation, the html2canvas library, which is a preset static rendering method, can be used to statically render the current animation frame into a static frame-divided picture. Among them, the html2canvas library can render HTML (HyperText Markup Language) elements (including animation elements) into a canvas object, and then extract image data from the canvas object and save it as a static frame-divided picture.

[0070] In specific implementation, other preset static rendering methods such as HTMLToImage and Puppeteerd can also be used to statically render the current animation frame to obtain a frame-divided image, which will not be elaborated here one by one.

[0071] Step A3: Jump to the next animation frame of the current animation frame through the animation delay property until the static rendering of each animation frame of the first animation is completed to obtain a frame sequence.

[0072] By modifying the animation delay property (animation-delay) of CSS, the start time of the animation is adjusted to the start time of the next animation frame. This usually involves setting the animation delay property to a negative value to indicate starting to play from a certain time point in the animation sequence. Repeat Step A1 to Step A2 to capture each animation frame of the first animated image frame by frame and render it as a frame-divided image. After each static rendering, update the animation delay property to point to the next animation frame until all frames in the first animation are statically rendered into frame-divided images.

[0073] Step 103: Compress each sub-frame image in the frame sequence according to a preset compression ratio to obtain a compressed frame sequence;

[0074] Among them, the preset compression ratio can be set according to actual needs and is not limited herein. In this embodiment, by compressing each sub-frame image in the frame sequence according to the preset compression ratio, the size of the animated image file can be significantly reduced. In actual applications, the compression of the frame sequence can be achieved through the webp-converter library. Specifically, other methods such as ImageOptim, image processing libraries, command-line tools, and video editing software can also be used to compress the frame sequence, which is not limited herein.

[0075] Step 104: Perform frame extraction processing on the compressed frame sequence according to the pixel-level comparison method to obtain the remaining retained frame images in the frame-extracted compressed frame sequence;

[0076] By performing pixel-level comparison on the compressed frame sequence, frames with relatively small differences between adjacent frames are identified and these redundant frames are removed, thereby retaining key frames and reducing the length of the frame sequence to further reduce the size of the animated image file.

[0077] Step 105: Synthesize the retained frame images to generate a second animated image.

[0078] Through steps 103 to 105, a second animated image with a small volume can be automatically generated, which can be quickly loaded during use, ensuring a smooth user experience and reducing losses caused by slow loading of animated images. In addition, the second animated image with a small volume can reduce the occupation of storage resources and lower the server bandwidth cost and cloud storage cost.

[0079] Through this application, the processing such as compression and frame extraction of high-frame-rate animated images can be automatically completed, effectively reducing the volume of the animated image file and solving the technical problem of the currently too large animated image file.

[0080] As Figure 3 shown, as an alternative embodiment, for the method as described above, step 101 of generating the first animated image based on the target picture includes the following steps:

[0081] Step 301: Respond to the operation of selecting dynamic effect elements for the target picture to determine the dynamic effect elements in the target picture;

[0082] The user can select the dynamic effect elements to which the dynamic effect is desired to be added on the target picture through operations such as clicking and dragging. These dynamic effect elements can be any part of the target picture, such as characters, objects, or backgrounds, etc., which is not limited herein. As Figure 2 shown, the patterns of the horn, snap up immediately, the annual gold card at a discount of up to 5.8 folds, and the double-eleven shopping spree in the target picture can be selected as the dynamic effect elements respectively.

[0083] Step 302: In response to a dynamic effect selection operation for a dynamic effect element, determine the dynamic effect of the dynamic effect element.

[0084] After determining the dynamic effect elements, the user can select specific dynamic effects for these dynamic effect elements. The dynamic effects can include various types such as size, positioning, zooming in and out, flashing, moving, rotating, scaling, color changing, etc., which are specifically set according to actual needs and are not limited here. When responding to the user's dynamic effect selection operation, the selected dynamic effect will be associated with the corresponding dynamic effect element to facilitate the generation of animated gifs.

[0085] For ease of understanding, as Figure 2 shown, for the dynamic effect element of the speaker, dynamic effects of size and positioning are set for it, and no animation is set; for the dynamic effect element of "Grab Now", dynamic effects of size and positioning are set for it, and the animation is set to a 2-second light swipe; for the dynamic effect element of "Annual Gold Card as low as 5.8 discount", dynamic effects of size and positioning are set for it, and the animation is set to a 1-second zooming in and out; for "Double Eleven Carnival Purchase", dynamic effects of size and positioning are set for it, and no animation is set (not shown in the figure).

[0086] As Figure 2 shown, in the right area of the animated gif generation interface, in addition to setting the dynamic effects corresponding to the dynamic effect elements, the user can also set the picture name, frames per second, clarity, etc. of the target picture, which are not limited here.

[0087] Compared with the traditional animated gif production that requires professional design software and a long production cycle, through the animated gif production process of this embodiment, only by selecting the dynamic effects and dynamic effect elements, the required animated gif can be quickly generated. This animated gif production process significantly shortens the time from the planning to the launch of the operation activity, improves the activity execution efficiency, and reduces the dependence on professional design software.

[0088] Step 303: Generate a first animated gif based on the dynamic effect element and the dynamic effect.

[0089] Based on the dynamic effect elements selected by the user and the dynamic effects specified for them, an animated gif containing these dynamic effects can be generated. During the process of generating the animated gif, frame-by-frame calculation and rendering of the dynamic effect elements will be performed according to the type and parameters of the dynamic effects, so as to create a first animated gif with a smooth and coherent animation effect.

[0090] As Figure 4 shown, as an optional implementation manner, in the method as described above, step 104 for performing frame extraction processing on the compressed frame sequence according to the pixel-level comparison method includes the following steps:

[0091] Step 401: For adjacent compressed frame images in the compressed frame sequence, obtain the image pixel points at each position of the compressed frame image.

[0092] For adjacent compressed frame images in the compressed frame sequence, the animated image generation system needs to access each frame and obtain the image pixel points (i.e., pixel point color values) at each position on each compressed frame image.

[0093] Step 402: Compare the colors of the image pixel points at each position of the adjacent compressed frame images.

[0094] The animated image generation system compares whether the image pixel points at the same position on two adjacent compressed frame images are the same, i.e., whether the color values are the same, in a color comparison.

[0095] Step 403: Determine the number of image pixel points with consistent color comparison.

[0096] After comparing all corresponding image pixel points of adjacent compressed frame images, the animated image generation system counts the number of image pixel points with the same color value or with a difference within an acceptable range. This number reflects the similarity degree between adjacent compressed frame images.

[0097] Step 404: Determine whether the number of image pixel points exceeds a preset number threshold.

[0098] The user can set a preset number threshold according to actual needs to determine whether adjacent compressed frame images are similar enough to be considered duplicates. If the number of pixel points with consistent color comparison exceeds this preset number threshold, then the animated image generation system considers these two adjacent compressed frame images to be duplicates or very similar.

[0099] Step 405: In the case where it is determined that the number of image pixel points exceeds the preset number threshold, perform frame extraction on the duplicate compressed frame images.

[0100] If the animated image generation system determines that adjacent compressed frame images are duplicates, then it will perform a frame extraction operation, i.e., delete or skip these duplicate frames, to reduce redundant information in the animated image file and achieve the purpose of reducing the size of the animated image file.

[0101] In summary, by comparing the pixel point colors of adjacent compressed frame images and judging the similarity of frames based on the number of pixel points with consistent color comparison, the animated image generation system can achieve effective frame extraction processing and achieve the purpose of reducing the size of the animated image file.

[0102] As Figure 5 shown, as an optional implementation manner, for the method as described above, step 105 synthesizes the retained frame images to generate a second animated image, including the following steps:

[0103] Step 501, obtain the total number of original frames, the original inter-frame delay, and the number of animation loops of the first animated image, and obtain the total number of first reserved frames of the reserved frame images;

[0104] Considering that among the mainstream formats of current dynamic images, webp is widely supported and has a higher compression ratio, gif2webp tool is selected to transcode non-webp format gif images into webp. After the transcoding is completed, use the webpinfo tool to obtain the total number of original frames, the original inter-frame delay, and the number of animation loops of the first animated image, and temporarily store this data through global variables.

[0105] Step 502, calculate the reserved frame inter-frame delay of the reserved frames according to the total number of original frames, the original inter-frame delay, and the total number of first reserved frames;

[0106] According to the total number of original frames, the original inter-frame delay, and the total number of first reserved frames, the new time interval between the reserved frames can be calculated, that is, the reserved frame inter-frame delay. This calculation involves ratio adjustment to ensure that the playback speed of the second animated image is similar to that of the first animated image or meets specific requirements.

[0107] Step 503, synthesize the reserved frame images according to the reserved frame inter-frame delay and the number of animation loops to generate the second animated image.

[0108] Use the calculated reserved frame inter-frame delay and the number of animation loops to arrange and synthesize the reserved frame images at the new time interval to generate the second animated image in webp format. This process involves existing technical contents such as image encoding and inter-frame transition processing to ensure the smoothness and quality of the second animated image, which will not be elaborated here.

[0109] In practical applications, the webp-converter library can also be directly used to re-synthesize the reserved frame images into the second animated image in webp format. Specifically in applications, according to requirements, the second animated image can be output as animated image files in other formats such as gif and apng, which are not limited here.

[0110] On the basis of Figure 1 refer to Figure 6 , Figure 6 is the flowchart of another method embodiment for generating an animated image provided by the embodiment of the present invention. Figure 6 The shown process may include the following steps:

[0111] Step 601, obtain a target picture, and generate a first animated image based on the target picture;

[0112] Step 602, display the first animated image on the display interface;

[0113] The display interface can be the above-mentioned moving picture generation interface, or a smart terminal used by the user, such as a mobile phone, a computer, a tablet, etc., so as to facilitate the user to determine whether the first moving picture meets the requirements.

[0114] Step 603, when responding to a first determination operation on the first moving picture, perform frame splitting on the first moving picture to obtain a frame sequence;

[0115] In the case where the user determines that the first moving picture meets the requirements, that is, after the user can perform a first determination operation such as single-clicking or double-clicking on the confirmation control on the display interface, perform the process of performing frame splitting on the first moving picture to obtain a frame sequence. In the case where the user determines that the first moving picture does not meet the requirements, the step of generating the first moving picture based on the target picture can be executed again until the first moving picture is made to meet the requirements.

[0116] Step 604, compress each split-frame image in the frame sequence according to a preset compression ratio to obtain a compressed frame sequence;

[0117] Step 605, send the compressed frame sequence to the display interface for display;

[0118] As Figure 7 shown in the figure is the successful display diagram of the moving picture production. The right side shows each compressed frame image in the compressed frame sequence.

[0119] Step 606, perform frame extraction on the compressed frame sequence according to the pixel-level comparison method to obtain the remaining retained frame images in the frame-extracted compressed frame sequence;

[0120] Step 607, highlight the retained frame images on the display interface;

[0121] As Figure 7 shown, the compressed frame images marked with a circled tick in each compressed frame image are the retained frame images. Specifically, when implementing, it is necessary to first obtain the frame numbers of the retained frame images, then query the compressed frame images in the compressed frame sequence with the same frame numbers as the retained frame images, and finally, perform prominent display of the found compressed frame images with preset identifiers (identifiers such as circled ticks, ticks, circles, etc., which are not limited here) to indicate that they are retained frame images.

[0122] Step 608, when responding to a second determination operation on the retained frame images, synthesize the retained frame images to generate a second moving picture;

[0123] When the user determines that the retained frame image is correct, that is, after the user can perform a second confirmation operation such as single-clicking or double-clicking on the confirmation control on the display interface, the retained frame images are synthesized to generate a second animated image. When the user determines that the retained frame image is incorrect, the step of performing frame extraction processing on the compressed frame sequence according to the pixel-level comparison method can be executed again to obtain the remaining retained frame images in the compressed frame sequence after frame extraction until the retained frame image is correct.

[0124] Step 609: Send the compressed frame sequence to the framed picture library for storage, and send the second animated image to the animated image result storage library for storage, and generate a download link for the second animated image so that the second animated image can be obtained from the animated image result storage library according to the download link.

[0125] The animated image generation system includes the above-mentioned framed picture library and animated image result storage library, so as to store the compressed frame sequence in the framed picture library and store the second animated image in the animated image result storage library to ensure the security and manageability of the data.

[0126] In actual application, the user can obtain the second animated image from the animated image result storage library through the download link at any time and place for use, enhancing the flexibility and availability of the data. For ease of understanding, as Figure 7 shown, the download link is displayed in the form of an animated image download control, and when the user clicks on the control, the second animated image can be browsed and displayed in the left area of the animated image production success display diagram.
