In the prior art, a boot animation in a terminal system is usually stored in a Read Only Memory (ROM) in the form of a sequence frame image, and a general animation may include several frames or even tens of frames of images. Assuming that the size of each frame image is the same, the storage size is M kb, the number of frames is N, and the whole fingerprint animation occupies the ROM with the size of (M x N) kb. Because the pixels of most areas of two adjacent frames of images in most animations are the same, the proportion of different pixels is very small. If the same pixel portion in the adjacent frame is removed, the total size can be theoretically optimized to (M + (M/10) × (N-1)) kb regardless of the byte occupancy in the digital encoding header of the image. Therefore, the embodiment of the present application provides an image processing method, which can implement that a server side preprocesses an animation into one or more merged images and configuration files, and a terminal side obtains the one or more merged images and configuration files from the server side and then can restore the animation, so that the ROM occupied by the one or more merged images and the configuration files is significantly reduced compared with a sequential frame image, and therefore, the ROM space can be saved to a certain extent.

For example, when a user enters a setting menu of a mobile phone and adds a new fingerprint, the user presses a fingerprint key once, and a fingerprint animation is played on a mobile phone interface correspondingly, where the fingerprint animation is composed of multiple frames of sequential frame images, as shown in fig. 4, the fingerprint animation includes ten consecutive frames of images, and the implementation manner in the prior art usually stores the ten frames of images of the fingerprint animation in a ROM, and occupies a relatively large amount of memory. In this embodiment of the application, the first electronic device may process ten frames of images in the fingerprint animation in advance to generate a plurality of combined images and a configuration file, and then the first electronic device sends the plurality of combined images and the configuration file to the second electronic device, so that the second electronic device restores the fingerprint animation. For example, the first electronic device may cut each of ten frames of images into a plurality of pixel blocks in the same manner, and then sequentially compare whether pixel blocks at the same positions in a subsequent frame of image and an adjacent previous frame of image are different. As shown in fig. 5, fig. 5a in fig. 5 is a different pixel block (the pixel block in the block is a different pixel block) determined after the second frame image in the fingerprint animation is compared with the first frame image, fig. 5b is a different pixel block (the pixel block in the block is a different pixel block) determined after the third frame image in the fingerprint animation is compared with the second frame image, and so on, until fig. 5c is a different pixel block (the pixel block in the block is a different pixel block) determined after the ninth frame image in the fingerprint animation is compared with the eighth frame image, and fig. 5d is a different pixel block (the pixel block in the block is a different pixel block) determined after the tenth frame image in the fingerprint animation is compared with the ninth frame image.

Further, the first electronic device writes the pixel blocks in the determined block into a merged image that includes all the pixel blocks of the first frame image in advance. In this way, all pixel blocks of the first frame image and all pixel blocks of the boxes are finally generated, as shown in fig. 6, while the configuration file records which frames each pixel block of the merged image is, and at which positions of these frames, respectively, so that the second electronic device can restore the fingerprint animation according to the configuration file and the merged image.

The image processing method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings and application scenarios. The following embodiments may be implemented in the electronic device 100 having the above-described hardware structure.

Referring to fig. 7, a flow of a first image processing method provided in an embodiment of the present application is exemplarily shown, and the method is executed by a first electronic device. The first electronic device may be a mobile phone, a tablet computer, a personal computer, or the like.

In step 201, the first electronic device divides N frames of original images in the animation into M pixel blocks in the same manner.

Illustratively, as shown in fig. 8, the first electronic device divides the first frame image, the second frame image and the third frame image in animation into 24 pixel blocks in the same manner, wherein the positions of the pixel blocks in different frame images are the same, for example, the coordinate position of the pixel block a of the first frame is the same as the coordinate position of the pixel block a2 of the second frame, and the coordinate position of the pixel block a3 of the third frame, the coordinate position of the pixel block B of the first frame is the same as the coordinate position of the pixel block B2 of the second frame, and the coordinate position of the pixel block B3 of the third frame, and so on. Or for example, the index value of the pixel block a of the first frame is the same as the index value of the pixel block a2 of the second frame, and the index value of the pixel block a3 of the third frame.

Step 202, the first electronic device writes M pixel blocks of a first frame original image in the N frame original images into a merged image. Wherein the M pixel blocks are all pixel blocks of the original image of the first frame.

For example, 24 pixel blocks in the first frame image in fig. 8 are written into the merged image.

Step 203, the first electronic device executes the following operations for the K-th frame original image, which is any one of the rest N-1 frame original images:

Returning to execute the traversal of the third pixel block in the K frame original image until all the M pixel blocks in the K frame original image are traversed; wherein M, N and K are positive integers greater than 1.

By way of example in fig. 8, the first electronic device first traverses the 24 pixel blocks a2 to X2 in the second frame image in sequence, where a2 pixel block is the same as a pixel block a of the first frame image, B2 pixel block is different from B pixel block of the first frame image, the first electronic device writes B2 pixel block into the merged image, C2 pixel block is the same as C pixel block of the first frame image, D2 pixel block is the same as D pixel block of the first frame image, and so on until X2 pixel block is the same as X pixel block of the first frame image. Finally the first electronic device writes b2, g2, and i2 of the second frame image into the merged image. Then, the first electronic device traverses again the 24 pixel blocks a3 to x3 in the third frame image, wherein the pixel block a3 is the same as the pixel block a2 of the second frame image, the pixel block b3 is different from the pixel block b2 of the second frame image, the first electronic device writes the pixel block b3 into the merged image, the pixel block c3 is the same as the pixel block c2 of the second frame image, the pixel block d3 is the same as the pixel block d2 of the second frame image, and so on until the pixel block x3 is the same as the pixel block x2 of the second frame image. Finally, the first electronic device writes b3, g3, i3, j3, o3, and r3 of the third frame image into the merged image. The merged image thus finally generated, as shown in fig. 8, pixel blocks in the merged image include a to X of the first frame image, and b2, g2, and i2 of the second frame image, and b3, g3, i3, j3, o3, and r3 of the third frame image.

It should be noted that the N original images in the images of the embodiment of the present application may be various types of images, such as RGB images; YUV images, RGBA images, YUVA images, and the like. The RGB image includes: a red R component, a green G component, and a blue B component. The RGBA image includes: a red R component, a green G component, a blue B component, and a transparency a component. The YUV image includes: a luminance Y component, a color difference U component, and a color difference V component. The YUVA image includes: a luminance Y component, a color difference U component, a color difference V component, and a transparency a component. Since each component represents a data value (also referred to as a component value) of a certain dimension of a pixel, and these component groups constitute pixel values, in this embodiment of the application, the first electronic device compares the pixel values of different pixel blocks, and if the pixel values of any one or more of the components are different, the pixel blocks are different.

Step 204, the first electronic device generates a configuration file, where the configuration file includes: the corresponding relation between the serial number of each pixel block in the finally generated combined image and the serial number of the original image, and the position information of each pixel block in the finally generated combined image in the corresponding original image.

Illustratively, the first electronic device assigns an index value to each pixel block position, and in fig. 8, the index values are (1,1), (1, 2) to (1, 4), (2,1), (2,2) to (2, 4) in order from top left to bottom right, and up to the last (6, 4). For example, the index value of the position of the pixel block b2 is (2,2), the index value of the position of the pixel block g2 is (2,3), and the index value of the position of the pixel block i2 is (3, 1). The configuration file finally generated by the first electronic device thus includes: in fig. 8, the correspondence relationship between each pixel block in the merged image and the first frame image, the second frame image, and the third frame image, and the index value of each pixel block in the image corresponding thereto are combined. Specifically, the configuration file includes: the pixel block a in the merged image in fig. 8 corresponds to the index value of the pixel a of the first frame image, the pixel a corresponds to the index value of the pixel a of the second frame image, the pixel a corresponds to the index value of the pixel block a2 of the second frame image, the pixel block a corresponds to the index value of the pixel block a3 of the third frame image, the pixel block B in the merged image in fig. 8 corresponds to the first frame image, the pixel block B corresponds to the index value of the pixel B of the first frame image, and so on until the pixel block r3 in the merged image in fig. 8 corresponds to the third frame image, and the pixel block r3 corresponds to the index value of the pixel r3 of the third frame image.

In a possible design, when the first electronic device is a personal computer, the first electronic device may directly send the finally generated combined image and configuration file to the second electronic device, or when receiving a call request of the second electronic device, send the finally generated combined image and configuration file to the second electronic device, so that the animation is restored by the second electronic device. When the first electronic device is a mobile phone or a tablet computer, the first electronic device can process the animation shared with the second electronic device into a combined image and a configuration file according to the method, and send the finally generated combined image and configuration file to the second electronic device, so that the ROM space of the second electronic device is saved.

In step 201, the pixel blocks generated by the first electronic device through division may be rectangular blocks, and the sizes of the pixel blocks of different animations are adjusted according to needs, that is, the size of the pixel block of the first electronic device should have a dynamic configuration capability, so that the first electronic device divides the sequence frame image through dynamically adjusting the size of the pixel block, and the benefit obtained by the whole system for processing the sequence frame can be optimized. Generally, the smaller the pixel block, the higher the contrast accuracy; as the smaller the pixel block is, the more the number of the pixel blocks divided by the whole image is, the more the configuration information quantity for describing the corresponding relation is, the larger the configuration file is, and the comprehensive benefit is relatively reduced. Therefore, the first electronic device needs to ensure accuracy and minimize the amount of configuration information describing the correspondence relationship. Assuming that the amount of configuration information describing the correspondence is referred to as "cost", factors affecting the "cost" include the resolution of the sequence frame images, the similarity between the sequence frames, the number of frames, and the like, and calculation is performed according to these parameters, so that an optimal value of the size of one pixel block can be found. And the configuration file comprises information of the width, the height, the size of the pixel block, the frame number of the animation and the like of the image.

In addition, the M pixel blocks in one frame image may be the same size or different sizes. Assuming that the resolution of the sequence frame image is W × H, the number of pixel blocks is divided, the horizontal direction is ω 1 — W/N (not divisible, rounded down), and the vertical direction is ω 2 — W/H (not divisible, rounded down); when the result of the W/N or H/N calculation is not an integer, according to the segmentation rule, a case may occur in which ω 1 × N < W (or ω 2 × N < H), that is, after the pixel blocks are rearranged, the total width is smaller than the sequence frame image width (or the total height is smaller than the sequence frame image height). Referring to fig. 9, when a sequence frame region cannot be divided by an integer multiple, as shown in fig. 9a, neither the width nor the height in fig. 9a can be divided by an integer multiple. The remaining regions are aligned with the right boundary, expanded from right to left, and divided into a series of pixel blocks as basic units, such as the rectangular regions shown on the right side of fig. 9 b.

It should be noted that, in step 204, the configuration file generated by the embodiment of the present application is generally in JSON format. Besides, the configuration file can be in JSON, XML and other formats, and developers can design the formats by themselves in order to keep the configuration file to have enough compression rate. The configuration file and the merged image can be sent to the second electronic device, stored on the second electronic device, or stored on the first electronic device, and when the second electronic device needs to play the animation, the request is sent to the first electronic device through the network, and the configuration file and the finally generated merged image are obtained from the first electronic device. In contrast, storing the configuration file and the merged image on the first electronic device can minimize the ROM space occupied by the second electronic device.

In a possible design, when the number of original images of the animation is large, or the similarity between the sequence frames is too low, the merged image generated by the first electronic device is large, which directly results in that when the second electronic device restores the animation, the time consumed for loading the merged image for the first time is large, and the animation playing effect is affected. Therefore, the first electronic device can generate a plurality of frames of merged images, each frame of merged images comprises a part of pixel blocks, so that the second electronic device can complete the initial animation playing only by loading part of the merged images when the animation is initially played, and the second electronic device can continuously load the other subsequent frames of merged images in the animation playing process. As the ROM space occupied by the single combined image becomes smaller, the time consumed by the second electronic equipment for loading the memory is reduced, and therefore the animation loading efficiency is improved.

In one possible design, when the first electronic device is a PC

Referring to fig. 10, a flow of a second image processing method provided in an embodiment of the present application is exemplarily shown, and the method is executed by the second electronic device side.

Step 301, obtaining a configuration file and a finally generated combined image from a first electronic device, where the configuration file includes: the method comprises a first corresponding relation between the serial number of each pixel block in the finally generated combined image and the serial number of the original image, and a second corresponding relation between the position information of each pixel block in the finally generated combined image and the corresponding original image.

Step 302, according to the first corresponding relationship, determining N groups of M target pixel blocks corresponding to the serial numbers of the N frames of original images from the finally generated merged image.

Step 303, determining the position information of each group of M target pixel blocks in the corresponding original image according to the second corresponding relationship.

And 304, arranging and combining the M target pixel blocks in each group according to the position information to generate the N frames of original images, and restoring animation according to the N frames of original images.

Illustratively, assume that the second electronic device first acquires the merged image in fig. 8 and the configuration file corresponding to the merged image from the first electronic device. And then the second electronic equipment determines that the pixel block corresponding to the first frame image comprises a pixel block A to a pixel block X from the merged image according to the first corresponding relation in the configuration file, and determines that the pixel block corresponding to the second frame image comprises a pixel block A, a pixel block b2, a pixel block C, a pixel block D to a pixel block f, a pixel block g2, a pixel block H to a pixel block X from the merged image. And analogizing in sequence until the pixel blocks corresponding to the third frame image are determined to be pixel block A to pixel block F, pixel block g3, pixel block H, pixel block i3, pixel block j3, pixel block H to pixel block N, pixel block o3, pixel block P to pixel block Q, pixel block r3, and pixel block S to pixel block X from the merged image. Further, the second electronic device determines, according to the second correspondence in the configuration file, that the pixel block corresponding to the first frame image has positional information of the pixel block a to the pixel block X in the first frame image, for example, index values (1,1), (1, 2) to (1, 4), (2,1), (2,2) to (2, 4) in this order. And determining the position information of the 24 pixel blocks corresponding to the second frame image in the second frame image, and so on until determining the position information of the 24 pixel blocks corresponding to the third frame image in the third frame image.

Furthermore, the second electronic device arranges and combines the first frame image, the second frame image and the third frame image according to the position information, so that the animation is finally restored according to the first frame image, the second frame image and the third frame image.

For another example, the second electronic device may restore the images of the 1 st frame to the 10 th frame shown in fig. 4 according to the merged image shown in fig. 6 and the corresponding relationship in the configuration file, and finally restore the fingerprint animation composed of the images of the 10 frames shown in fig. 4. The second electronic device may store the restored 10 frames of images in a Random Access Memory (RAM).

Referring to fig. 11, a flowchart of a third image processing method provided in an embodiment of the present application is exemplarily shown, and the method is executed by a first electronic device.

Step 401, dividing the N frames of original images in the animation into M pixel blocks in the same manner.

Illustratively, as shown in fig. 12, the first electronic device divides the first frame image, the second frame image, the third frame image, and the fourth frame image in the animation into 24 pixel blocks in the same manner.

Step 402, writing M pixel blocks of any one frame of original image in the N frames of original images into a merged image.

For example, 24 pixel blocks in the first frame image in fig. 12 are written into the merged image.

Step 403, traversing the remaining N-1 frames of original images, and performing a setting operation on each original image in the N-1 frames of original images, where the setting operation includes:

And when the second pixel block in the first image is different from all the pixel blocks in the current latest combined image, writing the second pixel block into the current latest combined image, otherwise, not writing the second pixel block into the current latest combined image. And returning to execute the third pixel block in the first image in a traversing manner until all the M pixel blocks in the first image are traversed.

Returning to execute a third pixel block in a second image in the N-1 frame original image according to the setting operation, writing the third pixel block into the current latest combined image when the third pixel block in the second image is different from all pixel blocks in the current latest combined image, and otherwise, not writing the third pixel block into the current latest combined image; and returning to execute the fourth pixel block in the second image until all the M pixel blocks in the second image are traversed.

Taking fig. 12 as an example, the first electronic device first traverses 24 pixel blocks a2 to x2 in the second frame image in sequence, wherein the first electronic device compares the pixel block a2 to be the same as the pixel block a of the current merged image, the first electronic device does not write the pixel block a2 into the merged image, and records this information in the configuration file (the pixel block a2 in the second frame image is the same as the pixel block a of the current latest merged image); the first electronic device compares the pixel block b2 with all pixel blocks of the current combined image, the first electronic device writes the pixel block b2 into the combined image, and records the position information of the pixel block b2 in the second frame image in the combined image in a configuration file, and at this time, the latest combined image at present also comprises the pixel block b2 besides all the pixel blocks of the first frame image; the first electronic device compares the pixel block C2 to be the same as the pixel block C of the current merged image, the first electronic device does not write the pixel block C2 into the merged image and records this information in the configuration file (the pixel block C2 in the second frame image is the same as the pixel block C of the current latest merged image), and so on until the first electronic device compares X2 to be the same as the pixel block X of the current latest merged image, the first electronic device does not write the pixel block X2 into the merged image and records this information in the configuration file (the pixel block X2 in the second frame image is the same as the pixel block X of the current latest merged image).

Further, the first electronic device sequentially traverses the 24 pixel blocks of a3 through x3 in the third frame image and the 24 pixel blocks of a4 through x4 in the fourth frame image again. The specific processing manner is similar to that of the second frame image, and is not described herein again.

In this way, as shown in fig. 13, the merged image finally generated by the first electronic device includes, in addition to all the pixel blocks of the first frame image, a pixel block b2, a pixel block g2, a pixel block i2, a pixel block g34, and a pixel block r 4.

Step 404, generating a configuration file, wherein the configuration file comprises: the corresponding relation between the serial number of each pixel block in the finally generated combined image and the serial number of the original image, and the position information of each pixel block in the finally generated combined image in the corresponding original image.

Illustratively, the first electronic device assigns an index value to the position of each pixel block in the newly generated merged image and the four-frame original image, and the index values of each pixel block of the four-frame original image are (1,1), (1, 2) to (1, 4), (2,1), (2,2) to (2, 4) in order from top left to bottom right, up to the last one (6, 4), in fig. 12. For example, the index value of the position of the pixel block b2 is (2,2), the index value of the position of the pixel block g2 is (2,3), and the index value of the position of the pixel block i2 is (3, 1). The configuration file finally generated by the first electronic device thus includes: the correspondence relationship of each pixel block in the finally generated merged image in fig. 13 with the first frame image, the second frame image, the third frame image, and the fourth frame image, and the index value of each pixel block in the image corresponding thereto. Specifically, the configuration file includes: the pixel block a in the merged image in fig. 13 corresponds to the first frame image, the second frame image, the third frame image, and the fourth frame image, and the pixel block a corresponds to the index value of the pixel a of the first frame image, the pixel a corresponds to the index value of the pixel block a2 of the second frame image, the pixel block a corresponds to the index value of the pixel block a3 of the third frame image, and the pixel block a corresponds to the index value of the pixel block a4 of the fourth frame image. The pixel block B in the merged image in fig. 13 corresponds to the first frame image, the second frame image and the fourth frame image, and the pixel block B corresponds to the index value of the pixel B of the first frame image, and corresponds to the index value of the pixel B3 of the third frame image, and corresponds to the index value of the fourth frame image B4, and so on, until the pixel block X4 in the merged image in fig. 13 corresponds to the first frame image, the second frame image, the third frame image and the fourth frame image, and the pixel block X4 corresponds to the index value of the pixel X of the first frame image, and the index value of the pixel X2 of the second frame image, and the index value of the pixel X3 of the third frame image, and the index value of the pixel X4 of the fourth frame image.

In a possible design, the first electronic device may directly send the finally generated combined image and configuration file to the second electronic device, or may send the finally generated combined image and configuration file to the second electronic device when receiving a call request of the second electronic device, so that the animation is restored by the second electronic device.

In addition, the first electronic device may select all pixel blocks of any one frame image from the four frame images to be written into the merged image, and the first electronic device may select to compare the pixel blocks of the frame image with all pixel blocks in the newly generated merged image, or may select to compare the pixel blocks of the frame image with all pixel blocks in the frame image that has already been compared.

It should be noted that, in step 401, the manner of dividing the generated pixel blocks and the format of the configuration file by the first electronic device are the same as the implementation of the first method, and are not described herein again.

Similarly, after the second electronic device obtains the configuration file and the finally generated merged image from the first electronic device, the process of restoring the animation is consistent with the second image processing method shown in fig. 10, and details are not repeated here.

Referring to fig. 14, a flow of a fourth image processing method provided in the embodiment of the present application is exemplarily shown, and the method is executed by the first electronic device.

Step 501, dividing N original images in the animation into M pixel blocks according to the same mode.

Step 502, writing M pixel blocks of a first image into a merged image, where the first image is any one of the N original images.

For example, the first image is the first frame image in fig. 12, and the first electronic device writes the 24 pixel blocks in the first frame image in fig. 12 into the merged image.

Step 503, traversing the other N-1 frames of original images, and executing a setting operation for each original image in the N-1 frames of original images, where the setting operation includes:

And returning and executing M pixel blocks in the fourth image in the N-1 frame original image according to the setting operation until all the images in the N-1 frame original image are traversed.

By way of example in fig. 12, the first electronic device first traverses 24 pixel blocks a2 to x2 in the second frame image in sequence, wherein the first electronic device compares whether the pixel block a2 is the same as all the pixel blocks of the first frame image, determines that the pixel block a2 is the same as the pixel block a of the first frame image, and the first electronic device does not write the pixel block a2 into the merged image and records this information in the configuration file (the pixel block a2 in the second frame image is the same as the pixel block a of the first frame image); the first electronic device compares the pixel block b2 with all the pixel blocks of the pixel block of the first frame image, the first electronic device writes the pixel block b2 into the merged image, and records the position information of the pixel block b2 in the second frame image in the merged image in the configuration file, and at this time, the latest merged image at present comprises the pixel block b2 besides all the pixel blocks of the first frame image; the first electronic device compares the pixel block C2 with all the pixel blocks of the first frame image, determines that the pixel block C2 is the same as the pixel block C of the first frame image, the first electronic device does not write the pixel block C2 into the merged image and records this information in the configuration file (the pixel block C2 in the second frame image is the same as the pixel block C of the first frame image), and so on until the first electronic device compares X2 to be the same as the pixel block X in the first frame image, the first electronic device does not write the pixel block X2 into the merged image and records this information in the configuration file (the pixel block X2 in the second frame image is the same as the pixel block X of the first frame image).

Further, the first electronic device traverses the 24 pixel blocks a3 to x3 in the third frame image again in sequence, wherein the first electronic device compares whether the pixel block a2 is the same as all the pixel blocks of the first frame image and the second frame image, determines that the pixel block a3 is the same as the pixel block a (or the pixel block a2) of the first frame image, does not write the pixel block a3 into the merged image, and records the information in the configuration file (the pixel block a3 in the third frame image is the same as the pixel block a of the first frame image); the first electronic device compares the block of pixels B3 with all the pixels of the first and second frame images, the block of pixels B3 being the same as the block of pixels B2 in the second frame image, the first electronic device does not write the block of pixels B3 into the merged image and records this information in the configuration file (the block of pixels B3 in the third frame image is the same as the block of pixels B of the first frame image); until the first electronic device comparison X3 is the same as the pixel block X in the first frame image, the first electronic device does not write pixel block X3 into the merged image and records this information in the configuration file (pixel block X3 in the third frame image is the same as pixel block X in the first frame image).

And so on, and 24 pixel blocks a4 through x4 in the fourth frame image. The specific processing manner is the same as above, and is not described herein again.

In this way, as shown in fig. 15, the merged image finally generated by the first electronic device includes, in addition to all the pixel blocks of the first frame image, a pixel block b2, a pixel block g2, a pixel block i2, a pixel block g3, a pixel block i3, and a pixel block r 4.

Step 404, the first electronic device generates a configuration file, where the configuration file includes: the corresponding relation between the serial number of each pixel block in the finally generated combined image and the serial number of the original image, and the position information of each pixel block in the finally generated combined image in the corresponding original image.

Illustratively, the first electronic device assigns an index value to the position of each pixel block in the newly generated merged image and the four-frame original image, and the index values of each pixel block of the four-frame original image are (1,1), (1, 2) to (1, 4), (2,1), (2,2) to (2, 4) in order from top left to bottom right, up to the last one (6, 4), in fig. 12. For example, the index value of the position of the pixel block b2 is (2,2), the index value of the position of the pixel block g2 is (2,3), and the index value of the position of the pixel block i2 is (3, 1). The configuration file finally generated by the first electronic device thus includes: the correspondence relationship of each pixel block in the finally generated merged image in fig. 15 with the first frame image, the second frame image, the third frame image, and the fourth frame image, and the index value of each pixel block in the image corresponding thereto. Specifically, the configuration file includes: the pixel block a in the merged image in fig. 15 corresponds to the first frame image, the second frame image, the third frame image, and the fourth frame image, and the pixel block a corresponds to the index value of the pixel a of the first frame image, the pixel a corresponds to the index value of the pixel block a2 of the second frame image, the pixel block a corresponds to the index value of the pixel block a3 of the third frame image, and the pixel block a corresponds to the index value of the pixel block a4 of the fourth frame image. The pixel block B in the merged image in fig. 15 corresponds to the first frame image, the second frame image, and the fourth frame image, and the pixel block B corresponds to the index value of the pixel B of the first frame image, and corresponds to the index value of the pixel B3 of the third frame image, and corresponds to the index value of the fourth frame image B4, and so on, until the pixel block X4 in the merged image in fig. 13 corresponds to the first frame image, the second frame image, the third frame image, and the fourth frame image, and the pixel block X4 corresponds to the index value of the pixel X of the first frame image, and the index value of the pixel X2 of the second frame image, and the index value of the pixel X3 of the third frame image, and the index value of the pixel X4 of the fourth frame image.

It should be noted that, in step 501, the manner of dividing the generated pixel blocks and the format of the configuration file by the first electronic device are the same as the implementation of the first method, and are not described herein again.

And the animation playing module 603 is configured to read multiple frames of original images output by the sequence frame restoring module 602, and encapsulate the multiple frames of original images into a sequence frame animation according to a requirement.

Therefore, the second electronic device can restore the animation only by configuring the file and combining the images, and the occupied ROM space is obviously reduced compared with the prior art that the sequence frame is directly played by polling.

The sequence frame restoring module 602 and the playing processing module 603 may execute in sequence, that is, the sequence frame restoring module 602 restores all sequence frames first, and the playing processing module 603 processes the sequence frame animation by using the conventional sequence frame technology. In addition, the sequence frame restoring module 602 may also execute synchronously with the playing processing module 603, and the sequence frame restoring module 602 outputs a frame to the playing processing module 603 every time it restores a frame, so that the two modules may run synchronously, thereby avoiding the problem of waiting for playing animation due to long processing time of the sequence frame restoring module, and making interactivity more friendly.
