Description

Technical Field

[0001] This application belongs to the field of image processing technology, specifically relating to a method and apparatus for creating raster animation. Background Technology

[0002] Raster animation, also known as moiré stripe animation, uses a raster plate to move across a base image, allowing the user's brain to automatically fill in the complete pattern based on the lines seen, thus creating an animation effect.

[0003] In related technologies, the "raster animation" effect is usually created by users using image editing software to edit multiple images to create an animation background. Then, a raster plate is placed on top of the animation background. At this point, users can manually move the raster plate on the animation background to demonstrate the raster animation effect.

[0004] However, the production process of the above-mentioned raster animation is not only complex but also has a high threshold, resulting in low efficiency in the entire raster animation production process. Summary of the Invention

[0007] Secondly, embodiments of this application provide a raster animation production apparatus, which includes a display module and a control module. The display module is used to display a first animation base image, which is generated based on first raster stripe parameters; and to overlay and display a raster plate control having the first raster stripe parameters on the first animation base image; the control module is used to control the movement of the raster stripes in the raster plate control displayed by the display module or the first animation base image displayed by the display module.

[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0041] The terms "at least one," "at least one of," etc., used in the specification and claims of this application refer to any one, any two, or a combination of two or more of the included items. For example, at least one of a, b, and c can mean: "a," "b," "c," "a and b," "a and c," "b and c," and "a, b, and c," where a, b, and c can be single or multiple. Similarly, "at least two" refers to two or more items, and its meaning is similar to that of "at least one."

[0042] The following description, in conjunction with the accompanying drawings, details the raster animation production method and apparatus provided in this application through specific embodiments and application scenarios.

[0043] The raster animation production method and apparatus provided in this application embodiment involve an electronic device displaying a first animation base image, which is generated based on first raster stripe parameters. Furthermore, a raster plate control with the first raster stripe parameters is overlaid on the first animation base image. The electronic device can then control the movement of the raster stripes or the first animation base image within the raster plate control. In this solution, by automatically overlaying a matching raster plate control onto the first animation base image, the electronic device can automatically demonstrate the raster animation effect by controlling the movement of the raster stripes or the first animation base image within the raster plate control. This not only reduces user intervention steps but also lowers the difficulty of raster animation production and improves production efficiency.

[0044] The raster animation production method provided in this application is executed by a raster animation production device. This device can be an independent device, an electronic device, or a functional module or entity within an electronic device. This application does not limit the specific device in this regard. The following will use an electronic device as an example to illustrate the raster animation production method provided in this application.

[0045] This application provides a method for creating raster animation. Figure 1 A flowchart illustrating a method for creating raster animation according to an embodiment of this application is shown. Figure 1 As shown, the raster animation production method provided in this application embodiment may include the following steps 201 to 203.

[0046] Step 201: The electronic device displays the first animation background image.

[0047] In this embodiment of the application, the first animation base map is generated based on the first raster stripe parameters.

[0048] In some embodiments of this application, the first grating stripe parameters include: grating stripe spacing and grating stripe width.

[0049] It should be noted that the above-mentioned raster stripe width is the width of the raster stripes shown in the raster animation, and the above-mentioned raster stripe interval is the interval between adjacent raster stripes shown in the raster animation.

[0050] It should be noted that the width of the grating stripes mentioned above is an integer multiple of the grating stripe spacing. For example, the grating stripe spacing in the first grating stripe parameter mentioned above can be 2, and the grating stripe width can be 4, which means the grating stripe width is twice the grating stripe spacing.

[0051] It should be noted that the width of the lenticular stripe spacing determines the clarity and detail of the lenticular animation; the smaller the lenticular stripe spacing, the clearer and more detailed the lenticular animation.

[0052] In some embodiments of this application, the first animation background image can be generated by the electronic device itself or can be received from other electronic devices. This application does not limit this.

[0053] In some embodiments of this application, when the first animation base map is an animation base map sent by another electronic device, the electronic device will also receive base map parameters used to generate the first animation base map at the same time as receiving the first animation base map.

[0054] For example, the base map parameters corresponding to the first animation base map include the first raster stripe parameters. Further, the base map parameters corresponding to the first animation base map may also include at least one of the following: the image size of the first animation base map, and the number of images used to generate the first animation base map.

[0055] In some embodiments of this application, the first animation base map is obtained based on at least two animation base maps.

[0056] It should be noted that each of the at least two animation base images mentioned above was generated based on the first raster stripe parameters. In other words, when stitching the animation base images, each animation base image used was generated based on the same raster stripe parameters.

[0057] Since raster animation relies primarily on an animation base image, a raster animation effect is created when the raster panel moves across the base image. Therefore, combining two or more animation base images allows us to obtain more detailed and richer animation base images.

[0058] In some embodiments of this application, the electronic device can combine the above-mentioned at least two animation base images in a first combination method to obtain the above-mentioned first animation base image, wherein the above-mentioned first combination method includes at least one of the following: superposition method and splicing method.

[0059] It should be noted that since an animated background image is essentially a transparent layer with content, and layers can be directly overlaid, multiple animated background images can be directly overlaid as long as the content within the overlay area does not overlap. Alternatively, electronic devices can directly merge at least two layers into one.

[0060] In some embodiments of this application, the splicing methods described above include, but are not limited to, top-bottom splicing and left-right splicing. The specific splicing method can be determined according to actual needs, and this application does not impose any limitations on it.

[0061] For example, in the process of an electronic device stitching together at least two animated background images in a top-bottom stitching manner, the alignment format of the at least two animated background images may include at least one of the following: center alignment format, left alignment format, or right alignment format.

[0062] For example, in the process of an electronic device stitching together at least two animated background images by means of left and right stitching, the alignment format of the at least two animated background images may include at least one of the following: center alignment format, top alignment format, or bottom alignment format.

[0063] In some embodiments of this application, the image size of the first animation base image is related to the image sizes of the at least two animation base images and the first combination method.

[0064] In some embodiments of this application, the image sizes of the at least two animated background images may be the same or different. For example, in a scenario where an electronic device stitches two animated background images together to form a first animated background image, the image height of the first animated background image is the maximum of the image heights of the two animated background images, and the image width of the first animated background image is the sum of the image widths of the two animated background images.

[0065] The following two examples illustrate the process of combining at least two animated background images.

[0066] Example 1: Animation background A1 is a background of a running mouse, and animation background A2 is a background of a running cat. Since the mouse in animation background A1 is located on the left side of the background, and the cat in animation background A2 is located on the right side, when animation backgrounds A1 and A2 are superimposed, the animated content "mouse" in A1 and the animated content "cat" in A2 do not overlap. Therefore, the electronic device can directly superimpose the two animation backgrounds to obtain animation background A3. Thus, when a raster control corresponding to animation background A3 is superimposed on animation background A3, the electronic device can control the raster stripes in the raster control or move animation background A3 to display a raster animation effect of a running mouse and a chasing cat.

[0067] Example 2, with Figure 2A The B1 animation base map shown, and Figure 2B Taking the B2 animation base image as an example, as shown Figure 2A As shown, the background image for animation B1 is a picture of a ball falling, as... Figure 2B As shown, the B2 animation background is a background image of a moving puppy. Electronic devices can directly stitch the two animation backgrounds side-by-side to obtain the result shown below. Figure 2CThe B3 animation background is shown. Thus, when a raster board control matching the B3 animation background is overlaid on it, the electronic device can control the raster stripes in the raster board control or move the B3 animation background, thereby displaying a raster animation effect of a ball falling from the sky and a dog chasing after it.

[0068] Step 202: The electronic device overlays a grating plate control with the first grating stripe parameter onto the first animation base image.

[0069] In some embodiments of this application, the grating plate control includes a plurality of grating stripes, and there is a gap between two adjacent grating stripes.

[0070] In some embodiments of this application, the grating stripes in the grating plate control described above can be multiple vertical stripes arranged horizontally or multiple horizontal stripes arranged vertically.

[0071] In some embodiments of this application, the control size of the above-mentioned raster plate control is smaller than or equal to the area size of the image display area of ​​the electronic device.

[0072] In some embodiments of this application, the raster plate control described above is a raster plate control adapted to the first animation base map described above.

[0073] It is understood that the grating stripes in the aforementioned grating plate control satisfy the aforementioned first grating stripe parameter. That is, the width of the grating stripes in the aforementioned grating plate control is equal to the grating stripe width contained in the first grating stripe parameter, and the spacing of the grating stripes in the aforementioned grating plate control is equal to the grating stripe spacing contained in the first grating stripe parameter.

[0074] In some embodiments of this application, the electronic device can determine a raster control that is compatible with the first animation background image based on the first raster stripe parameters corresponding to the first animation background image, and then overlay and display the compatible raster control on top of the first animation background image.

[0075] In one possible example, the electronic device has multiple raster control panels pre-stored, each with different raster stripe parameters. After displaying the first animation background, the electronic device can directly overlay the raster control panel with the first raster stripe parameter onto the first animation background.

[0076] In one possible example, the electronic device is equipped with a raster control that has multiple raster stripe patterns, each of which corresponds to different raster stripe parameters. After displaying a first animation background, the electronic device can overlay the raster control on the first animation background and set the raster stripe pattern in the raster control to the raster stripe pattern corresponding to the first raster stripe parameters.

[0077] In one possible example, after displaying the first animation background, the electronic device can generate a raster control with the first raster stripe parameters based on the first raster stripe parameters, and then overlay the raster control onto the first animation background. In other words, when displaying the raster control, the electronic device can draw corresponding raster stripes based on the first raster stripe parameters.

[0078] In some embodiments of this application, the electronic device receives a first input from a user and, in response to the first input, overlays and displays a raster plate control having a first raster stripe parameter on the first animation background.

[0079] For example, the first input described above is used to trigger an electronic device to perform a raster animation demonstration.

[0080] For example, the first input can be input from the user to any area on the first animation background image. Alternatively, if a playback control is displayed simultaneously with the first animation background image on the electronic device, the first input can be input from the user to that playback control.

[0081] For example, the first input mentioned above can be a user's click input, double-click input, long-press input, or other possible inputs. The specific input form can be determined according to actual needs, and this application does not limit it here.

[0082] For example, in conjunction with Example 2, such as Figure 3 As shown, when the phone displays a B3 animated background image through the album interface 10, if the user wants to display the raster animation effect corresponding to the B3 animated background image, they can click on the B3 animated background image, i.e., the first input mentioned above. At this time, as shown... Figure 4 As shown, it can trigger the electronic device to overlay and display the raster panel control 11 on the B3 animation base map.

[0083] Step 203: The electronic device controls the movement of the raster stripes or the first animation background in the raster plate control.

[0084] In some embodiments of this application, the electronic device controls the grating stripes or the first animation background in the grating plate control to move at a first moving speed.

[0085] It should be noted that once the raster stripes or the first animation background in the raster panel control begin to move, the raster animation effect corresponding to the first animation background will also be displayed, making it visible to the human eye.

[0086] It should be noted that the movement speed of the raster stripes or the first animation background in the raster panel control determines the final playback rate of the raster animation. The faster the movement speed, the faster the playback rate of the raster animation.

[0087] It should be noted that the playback rate of the above-mentioned raster animation can be considered as the demonstration speed of the raster animation effect. For example, for an animated background image of a running mouse, the faster the raster stripes in the raster control superimposed on it move, the faster the mouse will run in the final raster animation effect.

[0088] In some embodiments of this application, the first moving speed can be a preset speed or a speed set by the user.

[0089] In some embodiments of this application, the direction of movement of the grating stripes or the first animation background in the grating plate control of the electronic device is perpendicular to the direction of movement of the grating stripes in the grating plate control.

[0090] For example, when the raster stripes in the raster panel control are multiple vertical stripes arranged horizontally, the movement direction is horizontal. For example, combined with Figure 4 When the grating stripes in the grating plate control are multiple vertical stripes arranged horizontally, the grating stripes can be moved to the left or right.

[0091] For example, when the grating stripes in the grating panel control are multiple horizontal stripes arranged vertically, the direction of movement is vertical. For instance, when the grating stripes in the grating panel control are multiple horizontal stripes arranged vertically, the grating stripes can move upwards or downwards.

[0092] In some embodiments of this application, combined with Figure 1 ,like Figure 5 As shown, step 203 can be implemented through step 203a or step 203b.

[0093] Step 203a: When the image size of the first animation base image is larger than the control size of the raster board control, the electronic device controls the first animation base image to move.

[0094] Step 203b: When the image size of the first animation base image is less than or equal to the control size of the raster control, the electronic device controls the movement of the raster stripes in the raster control.

[0095] In some embodiments of this application, when the image size of the first animation background is larger than the control size of the raster panel control, i.e., for scenarios where the image size of the first animation background is large, the electronic device can display the raster animation effect by moving the first animation background and keeping the raster panel control stationary.

[0096] It is understandable that when the first animation base image forms a long scroll with enough content and logical coherence, the electronic device cannot display all the content of the first animation base image in the album interface. At this time, the electronic device can cover the entire display area with the raster panel control, keep it still, and control the movement of the first animation base image. Since the animation base image contains enough content and logical coherence, the raster animation displayed by the electronic device will be similar to an animated film with a storyline.

[0097] In some embodiments of this application, when the image size of the first animation background is smaller than the control size of the raster plate control, that is, in scenarios where the image size of the first animation background is small and the background content is limited, the electronic device can directly display the entire content of the first animation background, and then display the raster animation effect by controlling the movement of the raster stripes in the raster plate control.

[0098] In this way, the electronic device can determine the moving object based on the image size of the first animation background and the size of the raster control, thereby improving the flexibility of the electronic device in demonstrating raster animation. At the same time, when the first animation background is large, the electronic device can better display the content contained in the background animation by controlling the movement of the animation background, thus improving the demonstration effect of the raster animation.

[0099] In some embodiments of this application, after the electronic device controls the movement of the raster stripes or the first animation background in the raster plate control, the electronic device may also receive a second input from the user and, in response to the second input, control the raster stripes or the first animation background in the raster plate control to pause the movement, thereby stopping the raster animation demonstration.

[0100] In the raster animation production method provided in this application embodiment, an electronic device displays a first animation base image, which is generated based on first raster stripe parameters. Furthermore, a raster panel control with the first raster stripe parameters is overlaid on the first animation base image. The electronic device can then control the movement of the raster stripes or the first animation base image within the raster panel control to demonstrate the raster animation effect. In this solution, by automatically overlaying a matching raster panel control onto the first animation base image, the electronic device can automatically demonstrate the raster animation effect by controlling the movement of the raster stripes or the first animation base image within the raster panel control. This not only reduces user intervention steps but also lowers the difficulty of raster animation production and improves production efficiency.

[0101] In some embodiments of this application, combined with Figure 1 ,like Figure 6 As shown, prior to step 201 above, the raster animation production method provided in this application embodiment further includes steps 301 and 302.

[0102] Step 301: The electronic device acquires N frames of the first image.

[0103] In this embodiment of the application, N is an integer greater than 1.

[0104] In this embodiment of the application, at least two of the above N frames of the first image include the first subject being photographed.

[0105] In some embodiments of this application, at least one of the pose and position of the first photographed object is different in each of the above-mentioned at least two frames of images.

[0106] In some embodiments of this application, the aforementioned N-frame first images can be: N-frame first images obtained by continuous shooting, or N-frame image frames in a recorded video, or N-frame first images with similar content.

[0107] It should be noted that the smoothness of the raster animation effect is related to the number of frames in the first image. For example, the more frames in the first image, the smoother the movement of the subject in the final raster animation effect.

[0108] The following two examples will be used to illustrate the first image of the above N frames.

[0109] Example 3, such as Figures 7A to 7C As shown, Figures 7A to 7C The ball is positioned differently in the three images shown. Figure 7A The small ball in the image shown is located in the top area of ​​the image. Figure 7B The ball shown in the image is located in the middle region of the image. Figure 7C The ball shown in the image is located in the bottom area of ​​the image.

[0110] Example 4, such as 8A to Figure 8C As shown, Figures 8A to 8C The three images of puppies shown all depict puppies in different poses. Figure 8A The puppy in the image shown is standing. Figure 8B The puppy in the image shows raising one front leg. Figure 8C The image shown depicts a puppy raising one of its hind legs.

[0111] It should be noted that the above Figures 7A to 7C and Figures 8A to 8C The box in the image is only used to indicate the image size and is not displayed in actual applications.

[0112] In some embodiments of this application, combined with Figure 6 ,like Figure 9 As shown, step 301 can be implemented through steps 301a and 301b.

[0113] Step 301a: The electronic device acquires N frames of the fourth image.

[0114] Step 301b: The electronic device removes all image content except for the subject from each frame of the fourth image to obtain the N frames of the first image.

[0115] In this embodiment of the application, the fourth image is the original image obtained by the electronic device through shooting or recording video.

[0116] In some embodiments of this application, the subject being photographed may be a subject automatically detected by the electronic device from the fourth image, or it may be a subject selected by the user.

[0117] In some embodiments of this application, the phrase "the electronic device removes image content other than the subject in each frame of the fourth image" can be understood as: the electronic device removes image content other than the image content corresponding to the subject from the fourth image, or the electronic device sets the image content other than the image content corresponding to the subject in the fourth image to a solid color different from the color of the subject. For example, as... Figures 8A to 8C As shown, electronic devices can remove Figures 8A to 8C Extract all content except for the puppy. Figures 8A to 8C The corresponding multiple frames are images of puppies with different motion postures.

[0118] In some embodiments of this application, the electronic device can remove the image background in the fourth image to extract the moving subject from multiple frames of the fourth image, thereby reducing the impact of the image background in the image on the animation base map production process and improving the demonstration effect of raster animation.

[0119] In some embodiments of this application, step 301a above can be specifically implemented by step 301a1 below.

[0120] Step 301a1: The electronic device captures N frames of fourth images, or records a first video, wherein the aforementioned N frames of fourth images are video frame images within a first time period in the first video.

[0121] In some embodiments of this application, the above-mentioned "capturing N frames of fourth images" can be: N frames of fourth images obtained by the electronic device through continuous shooting, or multiple similar images captured by the electronic device within a certain time period.

[0122] For example, such as Figure 10 As shown, when the phone displays the image capture interface 12, the user can point the phone at a puppy and press and hold the capture button 13 to capture multiple frames of the puppy through continuous shooting, and then select the image from them. Figures 8A to 8CImages of puppies in different poses and movements are shown.

[0123] In some embodiments of this application, the aforementioned "video frame image within the first time period" refers to the video frame corresponding to the video within the time period selected by the user in the first video.

[0124] For example, when the phone displays a video recording interface, a user can point the phone at a small dog and tap the record button to start recording video. After the user taps the record button again, the phone stops recording, resulting in a video clip containing the dog. The user can then select a time segment of video frames in the video editing interface, such as 5 to 6 seconds, so that the phone can capture... Figures 8A to 8C Images of puppies in different poses and movements are shown.

[0125] It should be noted that after acquiring multiple consecutive images by shooting or recording video, the electronic device can use all the captured images or select some images to create raster animation.

[0126] In this embodiment of the application, the electronic device can acquire multiple consecutive images by shooting or recording video. The electronic device can then create an animation base map for raster animation based on these multiple consecutive images, so that the raster animation effect of the demonstration is more continuous and the demonstration effect of the raster animation is improved.

[0127] Step 302: The electronic device generates a first animation base map based on the first grating stripe parameters and N frames of the first image.

[0128] In some embodiments of this application, the first grating stripe parameter can be a parameter preset by the electronic device or a parameter set by the user.

[0129] In some embodiments of this application, after the electronic device acquires N frames of the first image, the electronic device may display a settings window, which is used to prompt the user to manually set or modify the first grating stripe parameters corresponding to the N frames of the first image.

[0130] In this embodiment, the electronic device can automatically generate a first animation base map based on the acquired first grating stripe parameters and N frames of first images, thereby eliminating the need for excessive user involvement in the animation base map production process, reducing the complexity of the grating animation production process, and lowering the production threshold, thus improving the efficiency of grating animation production.

[0131] In some embodiments of this application, combined with Figure 9 ,like Figure 11 As shown, step 302 can be implemented through steps 401 to 403 as described below.

[0132] Step 401: The electronic device divides the i-th frame of the first image in N frames of the first image into regions according to the first grating stripe parameters, and obtains M first stripe regions.

[0133] In this embodiment of the application, i ∈ [1, ..., N].

[0134] In some embodiments of this application, each of the M first strip regions contains N sub-strip regions.

[0135] It should be noted that the area size of each of the M first strip regions mentioned above is the same.

[0136] It should be noted that all sub-strip regions within each of the M first strip regions have the same region size.

[0137] In some embodiments of this application, after acquiring N frames of the first image, the electronic device can determine that the final playback period of the raster animation is N, that is, the raster animation can be played in a loop once every N frames. Then, the electronic device can divide each frame of the first image into equal intervals based on the first raster stripe parameters, and take each N sub-strip regions as a period, and group the sub-strip regions within each period into a group to form a first strip region.

[0138] For example, for the first image of the i-th frame, the electronic device can divide the first image of the i-th frame into M×N sub-strip regions based on the image size of the first image of the i-th frame and the grating stripe width in the first grating stripe parameter. The width of each sub-strip region is the same as the grating stripe width. Then, the electronic device can group every N sub-strip regions together to obtain M first strip regions.

[0139] Example 5, combined with Example 4 above, with Figures 7A to 7C For example, suppose Figures 7A to 7C Each image of a small ball in the image has a width of 12. If the user sets the raster stripe width to 1, then for... Figures 7A to 7C In each of the three images of the ball, the phone divides the ball image into 12 sub-strip regions, and divides every 3 sub-strip regions into a cycle. The sub-strip regions in each cycle are grouped together, and the 3 sub-strip regions in each group form a first strip region, forming a total of 4 first strip regions.

[0140] Step 402: The electronic device sets the transparency of the images in each first strip region of the first image of the i-th frame to the first transparency, except for the i-th sub-strip region, to the first transparency, thereby obtaining the processed first image of the i-th frame.

[0141] In some embodiments of this application, the first transparency is a preset transparency or a user-defined transparency. For example, the first transparency can be 100%.

[0142] It should be noted that the electronic device adjusts the transparency of the sub-strip area in order to reduce the impact of other sub-strip areas on the creation of the raster animation base map while preserving the i-th sub-strip area.

[0143] For example, the electronic device sets the transparency of the images in each first strip region of the first image in the i-th frame to 100%, i.e., a fully transparent state, except for the i-th sub-strip region.

[0144] For example, with Figures 7A to 7C Taking the image of the small ball shown as an example, and referring to Example 5 above, it can be seen that... Figure 7A The image of the small ball shown can be divided into four first strip regions, each containing three sub-strip regions. The phone can retain these regions. Figure 7A The image of the ball shown is the image of the sub-strip region labeled 1 in each of the first stripe regions. The transparency of the images in the other sub-strip regions within each of the first stripe regions is set to 100%, specifically the transparency of the images of the sub-strip regions labeled 2 and 3 within each of the first stripe regions. Thus, the image is obtained as shown. Figure 12A The image shown is of the processed ball. Similarly, for... Figure 7B The image of the small ball shown can be saved by the phone. Figure 7B The image shows the sub-strip region numbered 2 within each of the first striped regions of the ball image, with the transparency of the sub-strip regions numbered 1 and 3 within each of the first striped regions set to 100%, to obtain the image shown. Figure 12B The image shown is of the processed sphere. For Figure 7C The image of the small ball shown can be saved by the phone. Figure 7C The image shows the sub-strip region numbered 3 within each of the first striped regions of the ball image, with the transparency of the sub-strip regions numbered 1 and 2 within each of the first striped regions set to 100%, to obtain the image shown. Figure 12C The image shown is of the processed ball.

[0145] It is understood that for each of the above N first images, each first image can be processed by executing the above steps 401 and 402.

[0146] Step 403: The electronic device overlays the processed N frames of the first image to generate the first animation base image.

[0147] In some embodiments of this application, since the sub-strip regions included in each frame of the processed N-frame first image are different, that is, the superposition of the processed N-frame first images will not cause occlusion, the electronic device can directly superimpose the processed N-frame first images to obtain the first animation base image.

[0148] In other words, because the content retained in each sub-strip region of the processed first image is different—that is, the image content retained in each frame of the processed first image is spatially different—overlaying multiple frames of processed first images will not cause content occlusion. Furthermore, since the areas in each frame of the processed first image that do not retain image content are transparent, they can be directly overlaid layer by layer to form an animation base image.

[0149] For example, in conjunction with the above Figures 12A to 12C ,like Figure 13 As shown, due to Figures 12A to 12C The three images shown are essentially transparent layers with content, and these layers can be directly overlaid. Therefore, the phone can directly display them. Figures 12A to 12C By superimposing the results, we can obtain the following: Figure 2A The background image shown is an animation of a small ball falling.

[0150] Similarly, combining the above Figures 8A to 8C By performing steps 401 to 403 above, the following can be obtained: Figure 2B The background image shown is an animation of a puppy running.

[0151] In this embodiment, the electronic device processes N frames of the first image based on the first grating stripe parameters to automatically generate the first animation base map. This eliminates the need for excessive user involvement in the animation base map creation process, reduces the complexity of the grating animation production process, and lowers the production threshold, thereby improving the efficiency of grating animation production.

[0152] In some embodiments of this application, the above-mentioned N frames of first images include at least X frames of second images and X frames of third images, wherein the X frames of second images include a first subject, the X frames of third images include a second subject, X is an integer greater than 1, and the above-mentioned N is greater than or equal to 2X.

[0153] In some embodiments of this application, combined with Figure 9 ,like Figure 14 As shown, step 302 can be implemented through steps 501 to 503 as described below.

[0154] Step 501: The electronic device processes the second image of frame X according to the first grating stripe parameters to generate the second animation base map.

[0155] Step 502: The electronic device processes the third image of frame X according to the first grating stripe parameters to generate the third animation base map.

[0156] Step 503: The electronic device obtains the first animation base map based on the second and third animation base maps.

[0157] In some embodiments of this application, the second and third images described above are merely examples. In practical applications, the N frames of the first image may also include images of other subjects, enabling the electronic device to create a more comprehensive animated background.

[0158] In some embodiments of this application, the electronic device can combine the second animation base image and the third animation base image according to a first combination method to obtain the first animation base image. The first combination method includes overlaying or splicing.

[0159] It should be noted that the process of how the electronic device combines the second and third animation base images according to the first combination method to obtain the first animation base image can be referred to the detailed description above of the process of combining multiple animation base images into one animation base image. The specific combination method is the same in both cases, and will not be repeated here to avoid repetition.

[0160] It should be noted that the second animation base map generation process shown in step 501 above can be processed with reference to the animation base map generation process described in steps 401 to 403 above. To avoid repetition, it will not be described again here.

[0161] Similarly, the process of generating the third animation base map shown in step 502 above can be processed with reference to the animation base map generation process described in steps 401 to 403 above. To avoid repetition, it will not be described again here.

[0162] It should be noted that the present application embodiment does not limit the execution order of the above steps 501 and 502. Step 501 can be executed first and then step 502, or step 502 can be executed first and then step 501, or steps 501 and 502 can be executed simultaneously.
