Optionally, if the n+1th frame of the dynamic wallpaper is the same as the n+2th frame of the dynamic wallpaper, the n+2th frame of the dynamic wallpaper is identified as the n+1th frame of the dynamic wallpaper.

Unnecessary repeated calculation and storage are avoided, and the algorithm efficiency is improved. No difference calculation and storage is required between consecutive identical frames. By identifying these same frames, the display device of the dynamic wallpaper may skip these redundant steps, thereby saving computing resources.

The display device of the dynamic wallpaper can divide the difference area in a consistent way by using the preset shape, so that all the fragment sets are ensured to have similar shapes and sizes. This helps to improve the consistency and predictability of subsequent processing steps. Segmentation using preset shapes may allow for more standardization and simplification of the process flow.

This helps to improve the accuracy and efficiency of subsequent processing steps. By subdividing the difference region into a set of fragments, the display device of the dynamic wallpaper may more efficiently store and transmit such difference information. Smaller sets of shards may reduce the occupation of memory space while also helping to transfer differential data more quickly. By extracting a third set of fragments that is different from the first set of fragments, the display device of the dynamic wallpaper may more finely process these particular areas. By performing a stitching operation on the third set of fragments, the display device of the dynamic wallpaper may more quickly construct the n+2 frame of the target dynamic wallpaper. By processing only the actually changed region, unnecessary redrawing or rendering operations can be reduced, thereby improving the display efficiency of the dynamic wallpaper.

This helps to more accurately determine the region of discrepancy, improving the accuracy of the subsequent processing steps. By dividing the n+1st frame and the n+2nd frame into sets of fragments, respectively, the display device of the dynamic wallpaper can perform efficient difference detection and processing on the fragments. The difference region calculation method based on the pixel correspondence allows the display device of the dynamic wallpaper to perform finer difference processing on the fragment set.
103. The difference area is stored as an n+2th frame of the target dynamic wallpaper, wherein the target dynamic wallpaper is obtained when all frames in the dynamic wallpaper are judged;
Specifically, the calculated difference region is stored as the n+2th frame. Checking whether the dynamic wallpaper has residual frames or not, and judging whether the dynamic wallpaper has residual frames or not: if yes, increasing n by 1, and returning to the step 3; and if not, ending the algorithm to obtain the target dynamic wallpaper.
Through the algorithm, the target dynamic wallpaper can be gradually constructed, and only the part which is different from the previous frame is stored, so that the aims of saving storage space and reducing the waste of computing resources are realized.

specifically, when a display request is detected, the 1 st frame is read from the target dynamic wallpaper. And displaying the read 1 st frame as the background color of the canvas. The operation can take the 1 st frame as the ground color of canvas when displaying dynamic wallpaper, and provides a foundation for the display of the subsequent frames.
105. Displaying an m+1st frame of the target dynamic wallpaper on the canvas in response to the display request, wherein m is an integer increasing from 1 and is less than or equal to n+1;
Specifically, m=1, n is set as the increment integer calculated in the previous step.
When a display request is detected, the next step is entered.
And reading the m+1st frame from the target dynamic wallpaper.
And displaying the read m+1st frame on a canvas.

Through the algorithm, the target dynamic wallpaper can be displayed frame by frame so as to respond to the display request, and smooth display of the dynamic wallpaper is realized. Only the changed area is updated each time, unnecessary redrawing or flickering is avoided, and accordingly the waste of computing resources is reduced.
Specifically, referring to fig. 3, fig. 3 is a schematic diagram showing a specific embodiment before step 101 of the method for displaying dynamic wallpaper according to an embodiment of the invention, where step 101 includes the following specific embodiments:

It is ensured that the source video of the dynamic wallpaper is desired by the user. For users unfamiliar with how to set dynamic wallpaper, the set threshold is lowered.
Specifically, referring to fig. 4, fig. 4 is a schematic diagram of a specific embodiment after step 101 of the method for displaying dynamic wallpaper according to an embodiment of the present invention, and the following specific implementation manner is further included after step 101:

In steps 108-112, the user can automatically add text information to the dynamic wallpaper by adding instructions, without manual manipulation, providing convenience. According to the method, the meaning of the text information is judged through semantic analysis, and the coordinates of the target area in the reference frame are determined according to the preset semantic type, so that the text information can be flexibly rendered in a proper area, and customization and individuation of the dynamic wallpaper are improved. According to the method, text information can be updated in the reference frame, so that the dynamic wallpaper can be dynamically changed according to the instruction of a user, and the interactivity and the dynamic property of the dynamic wallpaper are improved.
In the embodiment of the invention, when the dynamic wallpaper is detected, the display equipment of the dynamic wallpaper can capture the first frame of the dynamic wallpaper first and take the first frame as the basis for subsequent comparison and processing. The content of the dynamic wallpaper is then compared from frame to determine whether the two frames are identical. When the two frames are found to be different in content, the region of difference between the two frames is calculated. The difference region is stored as the n+2 frame of the target dynamic wallpaper, which means that the display device of the dynamic wallpaper will store the calculated difference region as a new frame, thereby constructing a new dynamic wallpaper. When the dynamic wallpaper is required to be displayed, the display device of the dynamic wallpaper takes the first frame as the background color of the canvas. And displaying the m+1st frame of the target dynamic wallpaper on the canvas in response to the display request. When it is detected that two consecutive frames are different, only the region of difference between the two frames is calculated, rather than recomputing the contents of the entire canvas. Unnecessary computation is reduced, especially for large-area varying areas. Since only the part that differs from the previous frame is stored instead of the whole new frame, the use of storage resources is also optimized. In a scenario with a large number of consecutive frames, the storage space requirement can be significantly reduced. When displaying dynamic wallpaper, the display device of the dynamic wallpaper only updates the changed area, not the entire canvas. Unnecessary redrawing or flickering is avoided, thereby reducing the computational burden of the GPU and CPU. Since the change of the dynamic wallpaper content can be automatically detected, the allocation of the computing resources can be adjusted according to the actual change condition of the wallpaper. The method and the device can more efficiently cope with the change of various dynamic contents, and further reduce the waste of computing resources.
