Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a wallpaper display method, electronic device and storage medium. Background Technology

[0002] In current electronic device usage scenarios, to enhance the user's visual experience, devices typically play transition animations associated with the wallpaper during status changes. However, when the user-set wallpaper size is smaller than the screen size, related technologies generally enlarge the user-set wallpaper according to the screen size to achieve full-screen display, generating lock screen and always-on wallpapers that are the same size as the screen. This method results in the inability to play transition animations during status changes, causing a monotonous visual presentation, which not only affects the overall display effect but also degrades the user experience. Summary of the Invention

[0003] This application discloses a wallpaper display method, electronic device, and storage medium, which can solve the technical problem that transition animations cannot be played in some scenarios.

[0004] The first aspect of this application discloses a wallpaper display method applied to an electronic device, the electronic device including a display screen, the method comprising: generating a transition animation based on a configuration image when the electronic device enters a preset state, the configuration image being obtained by preprocessing a wallpaper set by a user, the size of the configuration image being equal to a preset multiple of the size of the display screen; and playing the transition animation on the display screen.

[0005] The above technical solution allows for the preprocessing of a configuration image based on the user-defined wallpaper. This ensures the size of the preprocessed configuration image is a preset multiple of the display screen size, avoiding inappropriate operations due to size mismatches and effectively resolving the issue of discrepancies between the displayed wallpaper and the user-defined wallpaper. Furthermore, when an electronic device is detected entering a preset state, a transition animation can be generated and played based on the configuration image, addressing the problem of transition animations not playing in certain scenarios and diversifying the visual presentation.

[0006] In one possible implementation, the method further includes: after the transition animation finishes playing, displaying the last image frame of the transition animation, wherein the last image frame is a lock screen wallpaper or an always-on wallpaper determined based on the wallpaper.

[0007] With the above technical solution, after the transition animation is completed, the electronic device displays the lock screen wallpaper or the off-screen wallpaper. Since there is no need to re-render the wallpaper set by the user, the resources of the electronic device can be saved.

[0008] In one possible implementation, the method further includes: in response to a user operation, preprocessing the wallpaper according to the wallpaper size and a preset size to obtain the configuration image, wherein the preset size is a preset multiple of the screen size; and storing the configuration image in the cache of the electronic device.

[0009] By preprocessing the wallpaper using its original size and preset dimensions, the technical solution described above ensures that the configured image size is a preset multiple of the display screen size. Furthermore, since the wallpaper displayed on the screen is determined based on the configured image, the visual discrepancy between the displayed wallpaper and the user-set wallpaper is resolved. Additionally, storing the configured image in a cache reduces the need for wallpaper loading to some extent.

[0010] In one possible implementation, the user operation includes any one of the following: power-on operation, wallpaper setting operation, and wallpaper changing operation.

[0011] In one possible implementation, the preprocessing of the wallpaper includes: if the size of the wallpaper is greater than or equal to the preset size, cropping the configuration image from the wallpaper according to the preset size.

[0012] By using the above technical solution, when the size of the wallpaper is greater than or equal to the preset size, the configuration image can be obtained by cropping it to the preset size, thus ensuring that the size of the configuration image is equal to the preset size.

[0013] In one possible implementation, the step of cropping the configuration image from the wallpaper according to the preset size includes: using a specified pixel point of the wallpaper as the reference pixel point of the configuration image, cropping an image with the preset size from the wallpaper as the configuration image.

[0014] By using the above technical solution, the configuration image can be cropped from the wallpaper by using the specified pixel points as the reference pixels.

[0015] In one possible implementation, the designated pixel point includes the midpoint of the lower boundary of the wallpaper, or the midpoint of the upper boundary of the wallpaper, or the center point of the wallpaper.

[0016] The above technical solutions can be used to crop configuration images in various ways to meet different user needs.

[0017] In one possible implementation, the preprocessing of the wallpaper includes: when the size of the wallpaper is smaller than the preset size but greater than or equal to the size of the display screen, performing image enlargement processing on the wallpaper to obtain the configuration image.

[0018] By employing the above technical solution, when the size of the wallpaper is smaller than the preset size but greater than or equal to the size of the display screen, by enlarging the wallpaper image, it is possible not only to ensure that the size of the configured image is equal to the preset size, but also to improve the viewing effect of the configured image.

[0019] In one possible implementation, the image enlargement process of the wallpaper includes: enlarging the wallpaper based on a first region to obtain a first image; enlarging the first image based on a second region to obtain a second image; and adjusting the clarity of a third region of the second image to obtain the configuration image.

[0020] The above technical solution allows for the expansion of the wallpaper using the first area and the first image using the second area, ensuring that the size of the second image equals the preset size. Simultaneously, by adjusting the clarity of the third area of ​​the second image, splicing and mirroring artifacts in the configuration image can be avoided, improving the imaging effect of the configuration image.

[0021] In one possible implementation, adjusting the sharpness of the third region of the second image to obtain the configuration image includes: blurring the third region of the second image and adjusting the transparency of the third region to obtain the configuration image.

[0022] By using the above technical solution, after blurring the third region, adjusting the transparency of the third region can improve the overall blending effect of the configuration image.

[0023] In one possible implementation, the preprocessing of the wallpaper includes: when the size of the wallpaper is smaller than the size of the display screen, enlarging the wallpaper based on the size of the display screen to obtain an enlarged image; and expanding the enlarged image to obtain the configuration image.

[0024] By employing the above technical solution, when the wallpaper size is smaller than the display screen size, the wallpaper can be enlarged using the display screen size, avoiding the inability to properly enlarge the image due to its small size. Simultaneously, by enlarging the enlarged image, the realism of the configured image can be improved.

[0025] In one possible implementation, the magnification process of the wallpaper includes: determining a first ratio based on the width of the wallpaper and the width of the display screen, and determining a second ratio based on the height of the wallpaper and the height of the display screen; determining the smaller ratio from the first ratio and the second ratio as a target ratio, and determining a magnification factor based on the target ratio; and magnifying the wallpaper using the magnification factor to obtain the magnified image.

[0026] Through the above technical solution, based on the first ratio of the width of the wallpaper to the width of the display screen and the second ratio of the height of the wallpaper to the height of the display screen, a smaller ratio is determined as the target ratio. Then, based on the target ratio, a reasonable magnification factor can be determined. By magnifying the wallpaper with the magnification factor, the rationality of the magnified image can be improved.

[0027] In one possible implementation, generating the transition animation based on the configuration image includes: scaling down the configuration image based on multiple scaling ratios in a first preset range to obtain a third image corresponding to each scaling ratio; cropping each third image according to the size of the display screen to obtain multiple image frames; and generating the transition animation based on the multiple image frames according to the sorting of the multiple scaling ratios.

[0028] The above technical solution allows for the acquisition of a third image corresponding to each scaling factor. Cropping this third image to the screen size ensures that the dimensions of multiple image frames are equal to the screen size. Sequencing these image frames according to the scaling factor order improves the smoothness of transition animations.

[0029] In one possible implementation, cropping each third image includes: using a preset pixel point of each third image as the reference pixel point of the corresponding image frame, determining a cropping area from each third image based on the size of the display screen; and cropping an image containing the corresponding cropping area from each third image to obtain the plurality of image frames.

[0030] Using the above technical solution, the preset pixel point of each third image can be used as the reference pixel point of the corresponding image frame, and the corresponding image frame can be cropped from each third image, which can ensure that the reference pixel point in each image frame is the same pixel point.

[0031] In one possible implementation, if the preset state is a screen-off state, generating the transition animation based on the plurality of image frames includes: generating the transition animation corresponding to the screen-off state based on the plurality of image frames in ascending order of the plurality of scaling ratios.

[0032] The above technical solution allows for the generation of transition animations based on multiple image frames, ensuring that transition animations can be played even when the electronic device is in a screen-off state. Furthermore, generating transition animations according to the ascending order of the multiple scaling ratios improves the smoothness of the transition animations.

[0033] In one possible implementation, if the preset state is a locked screen state, generating the transition animation based on the plurality of image frames includes: generating the transition animation corresponding to the locked screen state based on the plurality of image frames in descending order of the plurality of scaling ratios.

[0034] The above technical solution allows for the generation of transition animations based on multiple image frames, ensuring that transition animations can be played when the electronic device enters lock screen mode. Furthermore, generating transition animations according to the order of the multiple reduction ratios from largest to smallest improves the smoothness of the transition animations.

[0035] The second aspect of this application discloses an electronic device, which includes a processor and a memory, the memory being used to store instructions, and the processor being used to invoke the instructions in the memory to cause the electronic device to perform the wallpaper display method as described in the first aspect.

[0036] A third aspect of this application discloses a computer-readable storage medium including computer instructions that, when executed on an electronic device, cause the electronic device to perform the wallpaper display method as described in the first aspect.

[0037] It should be understood that the electronic device described in the second aspect and the computer-readable storage medium described in the third aspect above correspond to the method in the first aspect above. Therefore, the beneficial effects they can achieve can be referred to the beneficial effects in the corresponding methods provided above, and will not be repeated here. Attached Figure Description

[0069] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, words such as "exemplary," "or," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of words such as "exemplary," "or," and "for example" is intended to present the relevant concepts in a concrete manner.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. It should be understood that, unless otherwise stated, " / " in this application means "or". For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. "At least one" means one or more. "More than one" means two or more. For example, at least one of a, b, or c can represent: a, b, c, a and b, a and c, b and c, and a, b, and c. It should be understood that the order of steps shown in the flowcharts herein can be changed, and some can be omitted.

[0071] When using electronic devices (such as mobile phones, tablets, smartwatches, computers, etc.), users can set or change wallpapers according to their needs. However, after setting a wallpaper, in order to achieve full-screen display and avoid black bars on the screen, the wallpaper is usually enlarged by a certain factor based on the screen size. But this processing method will cause the displayed content to differ from the user-set wallpaper, and in some scenes, transition animations based on size changes cannot be generated and played, thus seriously affecting the user experience.

[0072] In terms of differences in displayed content, display discrepancies can occur when the set wallpaper size does not match the screen size. For example... Figure 1A As shown, when the wallpaper size is smaller than the screen size, the user-set wallpaper displays the characters "AAABBB" 1cm from the top edge of the screen, while the always-on wallpaper displayed on the screen displays the same characters 0.5cm from the top edge. The lock screen wallpaper displayed on the screen can only show part of the characters "AAABBB". For example... Figure 1B As shown, when the wallpaper size is larger than the screen size, the user-set lock screen wallpaper displays a portion of the characters "AAABBB" at the top edge of the screen, but the always-on wallpaper only displays a smaller portion of the characters, and the lock screen wallpaper does not display the characters at all. Therefore, regardless of whether the wallpaper size is smaller or larger than the screen size, after processing (e.g., magnification), there is a significant discrepancy between the displayed lock screen and always-on wallpaper and the user-set wallpaper in terms of content display, greatly affecting the user's expected wallpaper effect and user experience.

[0073] From the perspective of transition animations, when electronic devices switch states, such as entering a locked screen or screen-off state, they usually play transition animations associated with the wallpaper. For example... Figure 2A As shown, when the wallpaper size is larger than the screen size, a transition animation can be generated and played based on the size difference between the wallpaper and the screen. During the animation playback, the wallpaper gradually scales from its initial state to a display state adapted to the screen, providing the user with a smooth visual transition effect.

[0074] However, with Figure 2B For example, when the wallpaper size set by the user is smaller than the screen size, in order to achieve full-screen display, the wallpaper is usually enlarged to match the screen size, resulting in a lock screen wallpaper and an always-on wallpaper that are the same size as the screen. Since transition animations typically rely on changes in the size, position, or angle of the wallpaper under different states, when the wallpaper is enlarged to match the screen size, there is no room for variation during state transitions. Therefore, it's impossible to generate and play size-based transition animations, leading to a monotonous visual presentation that not only affects the overall display effect but also reduces the user experience.

[0075] To address the aforementioned issues, this application provides a wallpaper display method that preprocesses the user-set wallpaper so that the size of the preprocessed configuration image is equal to a preset multiple of the display screen size. Therefore, this application eliminates the need to enlarge the user-set wallpaper by a certain factor to display it in full screen, effectively resolving the discrepancy between the displayed content and the user-set wallpaper. When the electronic device enters a preset state, a transition animation can be generated based on the configuration image, solving the problem that some scenarios cannot generate transition animations based on the set wallpaper. This diversifies the visual presentation and improves the user experience.

[0076] The wallpaper display method provided in this application embodiment is applied to electronic devices including a display screen. Exemplarily, the electronic device in this application embodiment may be a mobile phone, tablet computer, desktop computer, laptop computer, handheld computer, notebook computer, ultra-mobile personal computer (UMPC), netbook, as well as cellular phones, personal digital assistants (PDAs), artificial intelligence (AI) devices, wearable devices, in-vehicle devices, smart home devices, and / or smart city devices, etc. This application embodiment does not impose any special limitations on the specific form of the electronic device. The electronic device includes an application processor, which is used to run an operating system, as described below. Figure 3 The software structure of an electronic device is illustrated by example.

[0077] See Figure 3The diagram shown is a software architecture diagram of an electronic device provided in an embodiment of this application. The layered architecture divides the software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. For example, the Android system, from top to bottom, consists of the application layer 101, framework layer 102, Android runtime and system libraries 103, hardware abstraction layer 104, kernel layer 105, and hardware layer 106.

[0078] Application layer 101 may include a series of application packages. For example, application packages may include applications such as camera, gallery, calendar, calling, map, navigation, WLAN, Bluetooth, music, video, SMS, device control services, etc.

[0079] The application layer 101 may further include a control module 1011. The control module 1011 can preprocess the user-set wallpaper to obtain a configuration image. The control module 1011 can also store the configuration image in the electronic device's cache. Upon detecting that the electronic device has entered a preset state, the control module 1011 can retrieve the configuration image from the cache and generate a transition animation based on the configuration image. The control module 1011 can also send the transition animation to the view module. The control module 1011 can also release the transition animation after it has finished playing.

[0080] The application layer 101 may also include an image expansion module 1012. In this embodiment, the preset size can be a preset multiple of the display screen size, and the preset multiple can be set and adjusted according to user needs. When the wallpaper size is smaller than the preset size but greater than or equal to the display screen size, the image expansion module 1012 can expand the wallpaper to obtain a configuration image. When the wallpaper size is smaller than the display screen size, the image expansion module 1012 can enlarge the wallpaper based on the display screen size to obtain an enlarged image, and then expand the enlarged image to obtain a configuration image.

[0081] In this embodiment of the application, the image expansion module 1012 can specifically expand the wallpaper based on the first area of ​​the wallpaper to obtain a first image, expand the first image based on the second area of ​​the first image to obtain a second image, and adjust the clarity of the third area of ​​the second image to obtain a configuration image.

[0082] The framework layer 102 provides an Application Programming Interface (API) and programming framework for applications in the application layer. The application framework layer includes predefined functions. For example, it may include a window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0083] The window manager manages window programs. It can obtain the screen size, determine the presence of a status bar, lock the screen, and capture screenshots. The content provider stores and retrieves data, making this data accessible to applications. Data can include video, images, audio, made and received phone calls, browsing history and bookmarks, phone books, etc. The view system includes visual controls, such as controls for displaying text and images. The view system can be used to build applications. The view system may also include a view module 1021, which can play transition animations on the screen. The view module 1021 can also send a completion notification to the control module after the transition animation has finished playing.

[0084] The display interface can consist of one or more views. For example, a display interface including a text notification icon can include a view displaying text and a view displaying images. The phone manager provides communication functions for electronic devices, such as managing call status (including connection, hang-up, etc.). The resource manager provides applications with various resources, such as localized strings, icons, images, layout files, video files, etc. The notification manager allows applications to display notification information in the status bar, which can be used to convey informational messages and can disappear automatically after a short pause without user interaction. For example, the notification manager is used to notify of download completion, message alerts, etc. The notification manager can also display notifications as icons or scrolling text in the system's top status bar, such as notifications from background applications, or as dialog windows on the screen. For example, displaying text messages in the status bar, emitting alert sounds, vibrating electronic devices, flashing indicator lights, etc.

[0085] The Android Runtime consists of the core libraries and the virtual machine. The Android runtime is responsible for the scheduling and management of the Android system. The core libraries consist of two parts: one part contains the functionalities that the Java language needs to call, and the other part contains the core Android libraries.

[0086] Application layer 101 and framework layer 102 run in a virtual machine. The virtual machine executes the Java files of the application layer and framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0087] System library 103 may include multiple functional modules. For example, a surface manager, media libraries, 3D graphics processing libraries (e.g., Open GLES), 2D graphics engines (e.g., SGL), etc.

[0088] The Surface Manager manages the display subsystem and provides fusion of 2D and 3D layers for multiple applications. The Media Library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG. The 3D Graphics Processing Library implements 3D graphics drawing, image rendering, compositing, and layer processing. The 2D Graphics Engine is the drawing engine for 2D graphics.

[0089] Hardware Abstraction Layer 104 runs in user space, encapsulates kernel-level drivers, and provides calling interfaces to the upper layers.

[0090] Kernel layer 105 is the layer between hardware and software. Kernel layer 105 contains at least the display driver, touch driver, audio driver, and sensor driver.

[0091] The kernel layer (105) is the core of the operating system for electronic devices. It is the first layer of software extension based on the hardware, providing the most basic functions of the operating system. It is the foundation for the operation of the operating system, responsible for managing system processes, memory, device drivers, files, and network systems, and determining the system's performance and stability. For example, the kernel layer can determine the timing of an application's operation on a certain part of the hardware.

[0092] Kernel layer 105 includes hardware-dependent programs such as interrupt handlers and device drivers, as well as basic, common, and frequently running modules such as clock management and process scheduling modules, and critical data structures. The kernel layer can be located within the processor or embedded in internal memory.

[0093] Hardware layer 106 includes the hardware of electronic devices, such as displays, buttons, cameras, etc.

[0094] To better understand the embodiments of this application, the wallpaper display method provided by the embodiments of this application will be described below with reference to the accompanying drawings. The following embodiments can be implemented independently or in combination with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0095] Figure 4 This is a flowchart illustrating a wallpaper display method provided in one embodiment of this application. The wallpaper display method is applied to an electronic device including a display screen. Depending on different requirements, the order of the steps in this flowchart can be changed, and some steps can be omitted. For example... Figure 4 As shown, the wallpaper display method includes the following process.

[0096] S401, in response to user operation, the control module of the electronic device preprocesses the wallpaper set by the user to obtain the configured image.

[0097] In one embodiment of this application, user operations may include, but are not limited to, power-on operations, wallpaper setting operations, and wallpaper changing operations. In one example, in response to a user's power-on operation on the electronic device, the electronic device can load a user-set wallpaper from a preset directory. The preset directory may store user-set custom wallpapers. In another example, the user can set a wallpaper as needed; for example, the user-set wallpaper may be a lock screen wallpaper and / or an always-on wallpaper. In response to a user's wallpaper setting or wallpaper changing operation on the electronic device, the electronic device can obtain the currently set wallpaper as the user-set wallpaper.

[0098] In one embodiment of this application, in response to a user operation, the control module in the electronic device (e.g., Figure 3 The control module 1011 shown can preprocess the user-set wallpaper based on the wallpaper size and a preset size to obtain a configuration image. The size of the configuration image can be equal to a preset multiple of the display screen size. The preset size can be a preset multiple of the display screen size, which can be set and adjusted according to user needs. For example, the preset multiple can be 1.12, 1.13, etc., and the display screen size can be represented by W1 and H1, where W1 represents the size of the display screen in the first dimension (e.g., width) and H1 represents the size of the display screen in the second dimension (e.g., height). Therefore, the preset size can be expressed as 1.12W1 and 1.12H1. This embodiment of the application, by preprocessing the wallpaper based on the wallpaper size and a preset size, ensures that the size of the configuration image is equal to a preset multiple of the display screen size. Furthermore, since the wallpaper displayed on the screen is determined based on the configuration image, it solves the problem of visual differences between the wallpaper displayed on the screen and the user-set wallpaper.

[0099] In one embodiment of this application, the method by which the electronic device preprocesses the wallpaper can be found in [reference needed]. Figure 5 The process is shown below. The following text combines... Figure 5 The process shown is explained below.

[0100] S4011, determine whether the wallpaper size is greater than or equal to the preset size.

[0101] In one embodiment of this application, if the width of the wallpaper is greater than or equal to a preset multiple of the width of the display screen, and the height of the wallpaper is greater than or equal to a preset multiple of the height of the display screen, the electronic device determines that the size of the wallpaper is greater than or equal to a preset size. If the width of the wallpaper is less than a preset multiple of the width of the display screen, or the height of the wallpaper is less than a preset multiple of the height of the display screen, the electronic device determines that the size of the wallpaper is less than a preset size.

[0102] In one embodiment of this application, if the size of the wallpaper is greater than or equal to a preset size, step S4012 is executed; if the size of the wallpaper is less than the preset size, step S4013 is executed.

[0103] S4012, based on the preset size, cuts out the configuration image from the wallpaper.

[0104] In one embodiment of this application, to meet different user needs, the midpoint of the bottom edge, the midpoint of the top edge, or the center point of the wallpaper can be used as a designated pixel point of the wallpaper. The electronic device uses the designated pixel point of the wallpaper as the reference pixel point for the configuration image, and crops an image with a preset size from the wallpaper as the configuration image. In this embodiment, when the size of the wallpaper is greater than or equal to the preset size, the configuration image is obtained by cropping to the preset size, ensuring that the size of the configuration image is equal to the preset size. Furthermore, by using the designated pixel point of the wallpaper as the reference pixel point for the configuration image, this embodiment can crop a configuration image from the wallpaper based on the designated pixel point.

[0105] In one example, the wallpaper dimensions are represented by W2 and H2, where W2 represents the wallpaper's dimensions in the first dimension (e.g., width), and H2 represents the wallpaper's dimensions in the second dimension (e.g., height). For example, combining... Figure 6A , Figure 6B and Figure 6C The diagram shows that if W1 = 5cm, H1 = 10cm, W2 = 6cm, H2 = 13cm, and the preset multiplier k is 1.12, calculations show that W2 / W1 = 1.2 > 1.12 and H2 / H1 = 1.3 > 1.12. Figure 6A As shown, an electronic device can use the midpoint of the bottom edge of the wallpaper as the reference pixel point for the configuration image. The width and height of the configuration image cropped from the wallpaper are represented as: W3 = 5.6cm, H3 = 11.2cm, where W3 represents the size of the configuration image in the first dimension (e.g., width), and H3 represents the size of the configuration image in the second dimension (e.g., height). For example... Figure 6B As shown, an electronic device can use the midpoint of the top boundary of the wallpaper as the reference pixel point for the configuration image, and crop the configuration image from the wallpaper to obtain a configuration image with the aforementioned dimensions. For example... Figure 6C As shown, the electronic device can use the center point of the wallpaper as the reference pixel point for the configuration image and crop the configuration image from the wallpaper to obtain the configuration image with the above-mentioned size.

[0106] S4013 determines whether the wallpaper size is greater than or equal to the screen size.

[0107] In one embodiment of this application, the size of the display screen can be the size of the full screen, or it can represent the size of the display area used to display various interfaces, images, videos and other objects.

[0108] In one embodiment of this application, if the width of the wallpaper is greater than or equal to the width of the display screen and the height of the wallpaper is greater than or equal to the height of the display screen, the electronic device determines that the size of the wallpaper is greater than or equal to the size of the display screen. If the width of the wallpaper is less than the width of the display screen or the height of the wallpaper is less than the height of the display screen, the electronic device determines that the size of the wallpaper is less than the size of the display screen.

[0109] In one embodiment of this application, if the size of the wallpaper is greater than or equal to the size of the display screen, step S4014 is executed; if the size of the lock screen wallpaper is smaller than the size of the display screen, step S4015 is executed.

[0110] S4014, perform image enlargement processing on the wallpaper to obtain the configuration image.

[0111] In one embodiment of this application, to address the issue of the wallpaper displayed on the screen differing from the wallpaper set by the user, the electronic device can perform image enlargement processing on the wallpaper to obtain a configuration image. The size of the configuration image is equal to a preset multiple of the screen size. The method by which the electronic device performs image enlargement processing on the wallpaper is described below. Figure 7 The process is illustrated. In another embodiment, the electronic device can also use AI image expansion to expand the wallpaper to obtain a configuration image.

[0112] In one example, when the width of the wallpaper is less than a preset multiple of the width of the display screen and the height of the wallpaper is greater than or equal to a preset multiple of the height of the display screen, the wallpaper is enlarged based on a first region to obtain a configuration image. The first region may include the area of ​​the wallpaper in a first direction (e.g., from left to right according to the width of the wallpaper) and a second direction (e.g., the opposite direction of the first direction, from right to left according to the width of the wallpaper).

[0113] In another example, when the width of the wallpaper is greater than or equal to a preset multiple of the width of the display screen and the height of the wallpaper is less than a preset multiple of the height of the display screen, the wallpaper is expanded based on the second region of the wallpaper to obtain a configuration image. The second region may include the area of ​​the wallpaper in the third direction of the second dimension (e.g., the direction from top to bottom according to the height of the wallpaper) and / or the fourth direction (e.g., the opposite direction of the third direction, the direction from bottom to top according to the height of the wallpaper).

[0114] In another example, when the width of the wallpaper is less than a preset multiple of the width of the display screen and the height of the wallpaper is less than a preset multiple of the height of the display screen, the electronic device expands the wallpaper based on a first area to obtain a first image, and expands the first image based on a second area to obtain a second image. The electronic device then adjusts the sharpness of a third area of ​​the second image to obtain a configuration image. The third area may include the first area and its corresponding expanded area, and the second area and its corresponding expanded area.

[0115] S4015 enlarges the wallpaper based on the screen size to obtain an enlarged image, and then performs image expansion processing on the enlarged image to obtain a configuration image.

[0116] In one embodiment of this application, the electronic device determines a first ratio based on the width of the wallpaper and the width of the display screen, and a second ratio based on the height of the wallpaper and the height of the display screen. The electronic device then selects the smaller ratio from the first and second ratios as a target ratio, determines a magnification factor based on the target ratio, and uses this magnification factor to enlarge the wallpaper, obtaining an enlarged image. The magnification factor can be the reciprocal of the target ratio. This embodiment of the application determines the smaller ratio as the target ratio based on the first ratio of the wallpaper width to the display screen width and the second ratio of the wallpaper height to the display screen height. Based on the target ratio, a reasonable magnification factor can be determined, and by enlarging the wallpaper using this factor, the reasonableness of the enlarged image can be improved.

[0117] Figure 8 It shows the size relationship between the wallpaper, the screen, and the enlarged image. For example... Figure 8 As shown, if the screen size is W1 = 5cm and H1 = 10cm, and the wallpaper size is W2 = 4cm and H2 = 9cm, the first ratio is calculated to be W2 / W1 = 0.8 and the second ratio is H2 / H1 = 0.9. Taking the first ratio of 0.8 as the target ratio, the magnification factor is 1 / 0.8 = 1.25. By magnifying the wallpaper with a magnification factor of 1.2, the size of the magnified image is obtained as W = 5cm and H = 11.25cm.

[0118] In one embodiment of this application, the method by which the electronic device performs image enlargement processing on the magnified image can be referred to below. Figure 7 The process is shown below.

[0119] S402, the control module stores the configuration image in the cache of the electronic device.

[0120] In one embodiment of this application, to reduce the number of wallpaper loading operations and quickly generate transition animations, the electronic device can store the configuration image in the device's cache. In response to a user's shutdown operation, or when the wallpaper is updated due to a wallpaper setting or change operation, the electronic device deletes the configuration image from the cache, thus avoiding excessive image space consumption on the electronic device.

[0121] S403, if the electronic device is detected to have entered a preset state, the control module retrieves the configuration image from the cache.

[0122] In one embodiment of this application, the preset state may include, but is not limited to, a screen-off state, a screen-locked state, and a screen-on state. In different states, the user can perform corresponding operations to control the electronic device to enter a screen-off state from a screen-locked state or a screen-on state, enter a screen-locked state from a screen-off state or a screen-on state, and enter a screen-on state from a screen-off state or a screen-locked state.

[0123] In one embodiment of this application, the electronic device can enter a screen-off state in response to receiving a screen-off command. The screen-off command can be a command generated by the electronic device after receiving a user's screen-off operation while in a locked screen state. The screen-off operation may include, but is not limited to, a user's click operation on the power button, or a user's touch operation on the lock screen icon displayed on the screen. This embodiment of the application does not limit the screen-off operation. For example, the electronic device can enter a screen-off state when it receives a user's voice command for a screen-off operation, and / or detects that the brightness of the display screen is less than a brightness threshold, and / or does not receive a user operation within a preset time.

[0124] In one embodiment of this application, the electronic device can enter a locked screen state in response to receiving a lock screen command. The lock screen command can be a command generated by the electronic device after receiving a user's screen-on operation when the screen is off. The screen-on operation may include, but is not limited to, a user's click operation on the power button, or a user's touch operation on the lock screen icon displayed on the screen. This embodiment of the application does not limit the screen-on operation. For example, the electronic device can enter a locked screen state when it receives a user's voice command for screen-on operation while the screen is off, and / or when the electronic device is in a screen-on state and has not received a user operation within a preset time.

[0125] In one embodiment of this application, when the electronic device detects that it has entered a preset state, the electronic device can retrieve a configuration image from the cache. Since this embodiment does not require reloading the wallpaper or reprocessing, the configuration image can be retrieved quickly.

[0126] S404 generates transition animations based on configuration images.

[0127] In one embodiment of this application, to provide better visual effects, when the electronic device detects that it has entered a screen-off or screen-locked state, it can generate a transition animation based on a configured image. In one example, the electronic device can draw multiple image frames in a wallpaper display layer and obtain a transition animation based on the multiple image frames.

[0128] In one embodiment of this application, the method for generating a transition animation includes: scaling down a configuration image based on multiple scaling ratios in a first preset range to obtain a third image corresponding to each scaling ratio; cropping each third image according to the size of the display screen to obtain multiple image frames; and generating a transition animation based on the multiple image frames according to the sorting of the multiple scaling ratios.

[0129] In this embodiment, the first preset interval can be constructed based on the initial scaling ratio and the ending scaling ratio. Both the initial scaling ratio and the ending scaling ratio can be set to values ​​greater than 1. The initial scaling ratio and the ending scaling ratio can be set and adjusted according to actual needs, and are not limited in practical applications. The initial scaling ratio can be greater than the ending scaling ratio. For example, the initial scaling ratio can be set to 1.12, and the ending scaling ratio can be set to 1.06. In one example, the electronic device can determine the first preset interval based on a third ratio of the initial scaling ratio to a preset multiple and a fourth ratio of the ending scaling ratio to a preset multiple. For example, if the initial scaling ratio is 1.12, the ending scaling ratio is 1.06, and the preset multiple is 1.12, the electronic device can determine the first preset interval as [1, 0.95] based on the third ratio 1.12 / 1.12 and the fourth ratio 1.06 / 1.12.

[0130] In this embodiment, the first preset interval includes multiple reduction ratios. The number of reduction ratios can be determined based on a preset frame rate and a preset duration. For example, if the frame rate of the transition animation is set to 120fps and the duration of the transition animation is set to 0.1s, then the number of reduction ratios is 12. In one example, the multiple reduction ratios can be any value within the first preset interval. In another example, the electronic device can determine the multiple reduction ratios based on the difference between the third ratio and the fourth ratio and the number of reduction ratios. The formula for the multiple reduction ratios can be: sN = K1 - N[(K1 - K2) / M], where sN can represent the Nth reduction ratio, K1 can represent the third ratio, K2 can represent the fourth ratio, and M can represent the number of reduction ratios. For example, if the third ratio is 1, the fourth ratio is 0.95, and the number of reduction ratios is 12, then the first reduction ratio can be s1 = 1 - 1 * [(1 - 0.95) / 120] = 0.9958. In this embodiment, the difference between the third ratio and the fourth ratio, and the number of multiple reduction ratios, can determine an ordered set of reduction ratios.

[0131] In this embodiment, the electronic device reduces the size of a configuration image according to multiple reduction ratios to obtain a third image corresponding to each reduction ratio. The size of each third image is greater than or equal to the size of the display screen. For example, the size of the configuration image is W3 = 5.6cm, H3 = 11.2cm, and the size of the display screen is W1 = 5cm, H1 = 10cm. The multiple reduction ratios include 0.98, 0.97, and 0.95. The electronic device reduces the size of the configuration image according to a reduction ratio of 0.98 to obtain a third image corresponding to a reduction ratio of 0.98, W4 = 5.488cm, H4 = 10.976cm. The electronic device reduces the size of the configuration image according to a reduction ratio of 0.97 to obtain a third image corresponding to a reduction ratio of 0.97, W4 = 5.488cm, H4 = 10.976cm. The electronic device reduces the size of the configuration image according to a reduction ratio of 0.95 to obtain a third image corresponding to a reduction ratio of 0.95, W4 = 5.488cm, H4 = 10.976cm.

[0132] In this embodiment, the preset pixel can be the midpoint of the lower boundary, the midpoint of the upper boundary, or the center point of a pixel in each third image. The electronic device can use the preset pixel of each third image as the reference pixel of the corresponding image frame, and determine a cropping region from each third image based on the size of the display screen. The size of the cropping region is equal to the size of the display screen. The electronic device crops an image containing the corresponding cropping region from each third image, obtaining multiple image frames. This embodiment, by using the preset pixel of each third image as the reference pixel of the corresponding image frame, can ensure that the reference pixel in each image frame is the same pixel.

[0133] In one example, if the second region of the first image only includes the region of the first image in a third direction (e.g., from top to bottom according to the image height) of the second dimension (e.g., the image height of the first image), the electronic device can use the midpoint of the lower boundary of each third image as the reference pixel point of the corresponding image frame to crop multiple image frames from each third image. For example Figure 9A As shown, if W1 = 5cm, H1 = 10cm, and the image corresponding to a reduction ratio of 0.97 is W4 = 5.488cm, H4 = 10.976cm, we can obtain the following: Figure 9A The image frame shown.

[0134] In another example, if the second region of the first image only includes the region of the first image in the fourth direction of the second dimension (e.g., the opposite direction of the third direction, the direction from bottom to top according to the image height), the electronic device can use the midpoint of the upper boundary of each third image as the reference pixel point of the corresponding image frame to crop multiple image frames from each third image. For example Figure 9B As shown, if W1 = 5cm, H1 = 10cm, and the image corresponding to a reduction ratio of 0.97 is W4 = 5.488cm, H4 = 10.976cm, we can obtain the following: Figure 9B The image frame shown.

[0135] In another example, if the second region of the first image includes the regions of the first image in the third and fourth directions, the electronic device can use the center point of each third image as the reference pixel point for the corresponding image frame to crop multiple image frames from each third image. For example Figure 9C As shown, if W1 = 5cm, H1 = 10cm, and the image corresponding to a reduction ratio of 0.97 is W4 = 5.488cm, H4 = 10.976cm, we can obtain the following: Figure 9C The image frame shown.

[0136] This application embodiment reduces the size of the configuration image by multiple reduction ratios within a first preset range, resulting in multiple corresponding third images. By cropping the third images according to the display screen size, multiple image frames with the same size as the display screen can be obtained. Based on a preset order of the multiple reduction ratios, a smooth transition animation can be generated.

[0137] In one embodiment of this application, the transition animation may include a transition animation corresponding to the screen-off state and a transition animation corresponding to the screen-locked state. In one example, if the preset state is the screen-off state, a transition animation corresponding to the screen-off state is generated based on multiple image frames in ascending order of scaling ratio. The last image frame of the transition animation corresponding to the screen-off state can be the screen-off wallpaper. For example... Figure 9D As shown, the configuration image obtained by the control module from the cache is 1.12 times the display screen size. After the view module loads the configuration image, the control module can reduce the size of the configuration image to 1 times the display screen size. When the screen is off, the control module can adjust the size of the configuration image to 1.06 times the display screen size before displaying it. At this time, the size of the off-screen wallpaper displayed in the off-screen state is 0.95 times the size of the configuration image in the cache. This embodiment can generate transition animations based on multiple image frames, ensuring that transition animations can be played when the electronic device enters the off-screen state. Furthermore, generating transition animations according to multiple scaling ratios from smallest to largest can improve the smoothness of the transition animations.

[0138] In another example, if the preset state is a lock screen, a transition animation corresponding to the lock screen state is generated based on multiple image frames, arranged in descending order of scaling ratio. The last image frame of the transition animation corresponding to the lock screen state is the lock screen wallpaper. For example... Figure 9EAs shown, the configuration image obtained by the control module from the cache is 1.12 times the display screen size. After the view module loads the configuration image, the control module can reduce the size of the configuration image to 1 times the display screen size. When the screen is locked, the control module can adjust the size of the configuration image to 1.12 times the display screen size before displaying it. At this time, the size of the lock screen wallpaper displayed in the lock screen state is the size of the configuration image in the cache. This embodiment can generate transition animations based on multiple image frames to ensure that the transition animation can be played when the electronic device enters the lock screen state. Furthermore, generating transition animations according to multiple reduction ratios from largest to smallest can improve the smoothness of the transition animations.

[0139] S405 sends the transition animation to the view module.

[0140] In one embodiment of this application, the control module can send transition animations to the view module for display.

[0141] S406, the view module plays transition animations on the display screen.

[0142] In one embodiment of this application, after the transition animation finishes playing, the last image frame of the transition animation is displayed. This last image frame is a lock screen wallpaper or an always-on wallpaper determined based on the wallpaper. For example, when the electronic device is in a lock screen state, it plays a transition animation corresponding to the lock screen state; after the transition animation finishes playing, the electronic device displays the lock screen wallpaper. Similarly, when the electronic device is in a always-on state, it plays a transition animation corresponding to the always-on state; after the transition animation finishes playing, the electronic device displays the always-on wallpaper. This embodiment of the application displays the lock screen wallpaper or always-on wallpaper after the transition animation finishes playing. Since it eliminates the need to re-render the user-set wallpaper, it saves the resources of the electronic device.

[0143] S407, the view module sends a notification message indicating that playback has been completed to the control module.

[0144] In one embodiment of this application, after the view module finishes playing the transition animation, it sends a notification message to the control module indicating that playback has been completed.

[0145] S408, control module releases transition animation.

[0146] In one embodiment of this application, after receiving a notification that playback has been completed, the control module can release the transition animation. For example, the control module can delete the transition animation to avoid the transition animation occupying the resources of the electronic device.

[0147] In the wallpaper display method of this application embodiment, a configuration image can be obtained by preprocessing the wallpaper set by the user, such that the size of the preprocessed configuration image is equal to a preset multiple of the screen size. This avoids inappropriate operations due to size mismatch and effectively solves the problem of differences between the wallpaper displayed on the screen and the wallpaper set by the user. Furthermore, when the electronic device is detected to have entered a preset state, a transition animation can be generated and played based on the configuration image, solving the problem of transition animations not being playable in some scenarios and diversifying the visual presentation methods.

[0148] See Figure 7 The diagram shown is a detailed flowchart of wallpaper enlargement processing provided in one embodiment of this application.

[0149] S701, based on the first area of ​​the wallpaper, expand the wallpaper to obtain the first image.

[0150] The first region may include the region of the wallpaper in the first direction of the first dimension (e.g., the direction from left to right according to the width of the wallpaper) (hereinafter referred to as the "left sub-region") and the region of the wallpaper in the second direction of the first dimension (e.g., the opposite direction of the first direction, the direction from right to left according to the width of the wallpaper) (hereinafter referred to as the "right sub-region").

[0151] In one embodiment of this application, the electronic device can determine a first region based on a first direction and a second direction of a first dimension. In one example, the electronic device can determine a first dividing line parallel to the boundary of the wallpaper along the first direction and the second direction of the first dimension of the wallpaper, according to the dividing size of the first dimension, and cut the first region from the wallpaper according to the first dividing line. The dividing size of the first dimension can be determined based on a preset multiple, for example, [(k-1) / 2]W2, where k represents the preset multiple and W2 represents the size of the wallpaper in the first dimension (e.g., width). For example, the preset multiple is 1.12 times, and the dividing size of the first dimension is 0.06W2. Figure 10 As shown, the electronic device can determine two first dividing lines based on the boundary line at the top position in the first direction and the division dimension in the first dimension, and the boundary line at the top position in the second direction and the division dimension in the first dimension. The wallpaper can then be divided according to these first dividing lines to obtain the desired result. Figure 10 The first region shown.

[0152] In one embodiment of this application, the electronic device can mirror a first area of ​​the wallpaper to obtain an expanded area. In this embodiment, the electronic device can mirror the expanded area corresponding to each first area based on the pixel values ​​of the pixels within each first area. The pixels in the expanded area correspond to the pixels in the corresponding first area; for example, the pixel values ​​of the pixels in the expanded area are equal to the pixel values ​​of the pixels in the corresponding first area.

[0153] See Figure 11 The image shown is an example diagram illustrating wallpaper expansion processing according to an embodiment of this application. For example... Figure 11 As shown, the number of each pixel in the wallpaper can be determined. The pixels in the wallpaper can include pixels 1, 2, 3, ..., 48. The area formed by pixels 1, 2, 7, 8, 13, 14, 19, 20, 25, 26, 31, 32, 37, 38, 43, and 44 (e.g.) Figure 11 The area shown by the solid red line in the middle) is taken as the first region, and the region formed by pixels 5, 6, 11, 12, 17, 18, 23, 24, 29, 30, 35, 36, 41, 42, 47, and 48 (for example) Figure 11 The area shown by the red dashed line in the middle) is considered as another first region. Based on the pixel values ​​of the pixels in the first region, the pixels outside the wallpaper boundary can be mirrored to obtain the expanded area corresponding to the first region (e.g., Figure 11 (The area shown in the purple box). For example, using pixels 1, 7, 13, 19, 25, 31, 37, and 43 at the edge of the wallpaper as reflection axes, the expanded area corresponding to the first area shown by the red solid line can be determined as the area shown in the purple solid box (for example, the area formed by pixels 2, 1, 8, 7, 14, 13, 20, 19, 26, 25, 32, 31, 38, 37, 44, and 43). Similarly, using pixels 6, 12, 18, 24, 30, 36, 42, and 48 at the edge of the wallpaper as reflection axes, the expanded area corresponding to the first area shown by the red dashed line can be determined as the area shown in the purple dashed box (for example, the area formed by pixels 6, 5, 12, 11, 18, 17, 24, 23, 30, 29, 36, 35, 42, 41, 48, and 47).

[0154] In one embodiment of this application, the electronic device stitches the wallpaper with the expanded area corresponding to the first area to obtain a first image, for example... Figure 11 The first image shown.

[0155] S702, based on the second region of the first image, the first image is expanded to obtain the second image.

[0156] The second region may include the region of the first image in a third direction of the second dimension (e.g., the direction from top to bottom according to the height of the first image) (hereinafter referred to as the "top sub-region") and / or the region of the first image in a fourth direction of the second dimension (e.g., the opposite direction of the third direction, the direction from bottom to top according to the height of the first image) (hereinafter referred to as the "bottom sub-region").

[0157] In one embodiment of this application, the electronic device can determine a second region based on a third direction in the second dimension and / or a fourth direction. In one example, the electronic device can determine a second dividing line parallel to the boundary of the first image along a third direction in the second dimension, according to a dividing size in the second dimension. The region of the first image in the third direction is then cut from the first image according to the second dividing line as the second region. The dividing size in the second dimension can be determined based on a preset multiple, for example, [(k-1) / 2]H2, where k represents the preset multiple and H2 represents the size (e.g., height) of the first image in the second dimension. For example, a preset multiple of 1.12 results in a dividing size of 0.06H2 in the second dimension. Figure 12A As shown, the electronic device can determine a second segmentation line based on the boundary line at the top position of the third dimension and the segmentation size of the second dimension, and then segment the first image according to the second segmentation line to obtain the following: Figure 12A The second region shown.

[0158] In another example, the electronic device can determine a third dividing line parallel to the boundary of the first image along the fourth direction of the second dimension, according to the segmentation size of the second dimension, and cut out the region of the first image in the fourth direction based on the third dividing line as the second region. For example... Figure 12B As shown, the electronic device can determine a third segmentation line based on the boundary point at the top position in the fourth direction and the segmentation size in the second dimension, and then segment the first image according to the third segmentation line to obtain the following: Figure 12B The second region shown.

[0159] In another example, the electronic device can define the area of ​​the first image in the third direction and the area in the fourth direction as the second region, for example... Figure 12C The second region shown.

[0160] In one embodiment of this application, the electronic device can mirror a second region of a first image to obtain an expanded region corresponding to the second region. In this embodiment, the electronic device can mirror the expanded region corresponding to the second region based on the pixel values ​​of the pixels within the second region. The pixels within the expanded region correspond to the pixels within the corresponding second region; for example, the pixel value of a pixel within the expanded region is the pixel value of the corresponding pixel within the second region.

[0161] For example Figure 13 The image shown is an example of an augmentation of a first image provided in an embodiment of this application. For example... Figure 13 As shown, the number of each pixel in the first image can be determined. The pixels in the first image may include pixels 2, 1, 1, 2, 3, 4, 5, 6, 6, 5, ..., 48, 48, 47. The region formed by pixels 2, 1, 1, 2, 3, 4, 5, 6, 6, 5 (e.g., ...) can be defined as... Figure 13 The area shown by the solid orange line in the middle is designated as the second region. Based on the pixel values ​​of the pixels in the second region, the pixels outside the boundary of the first image can be mirrored to obtain the expanded region corresponding to the second region. For example, using pixels 2, 1, 1, 2, 3, 4, 5, 6, 6, 5 at the boundary of the first image as the reflection axis for mirror mapping, the expanded region corresponding to the second region can be determined as the area shown by the solid blue line.

[0162] In one embodiment of this application, the electronic device stitches together the first image and the corresponding extended region of the second region to obtain the second image, for example... Figure 13 The second image C is shown.

[0163] In another embodiment, the execution order of steps S702 and S701 can be reversed. For example, the electronic device can first determine a second region along a third direction (e.g., from top to bottom according to the height of the wallpaper) and / or a fourth direction of the second dimension of the wallpaper, and then mirror the wallpaper based on the second region to obtain a first image. The electronic device determines a first region along the first image in the first and second directions of the first dimension, and then mirrors the first image based on the first region to obtain a second image.

[0164] S703, the sharpness of the third region of the second image is adjusted to obtain the configuration image.

[0165] The third region includes the first region and its corresponding extended region, the second region and its corresponding extended region, the first region includes the left sub-region and the right sub-region, and the second region includes the top sub-region and / or the bottom sub-region.

[0166] In one embodiment of this application, the electronic device blurs the third region and adjusts the transparency of the third region to obtain a configuration image.

[0167] In the embodiments of this application, the method of blurring is not specifically limited. For example, the third region can be blurred by mean filtering or Gaussian filtering, or the third region can be blurred by a preset model. The preset model can be used to blur the image.

[0168] In this embodiment, when the third region includes the extended region corresponding to the left sub-region, the extended region corresponding to the right sub-region, and the extended region corresponding to the top sub-region, the electronic device can adjust the transparency of the extended region corresponding to the left sub-region to the left sub-region along a first direction of the first dimension of the third image (e.g., from left to right according to the image width) based on a first transparency range. The first transparency range can be set to 100%-0%. The electronic device can adjust the transparency of the extended region corresponding to the right sub-region to the right sub-region along a second direction of the first dimension of the third image (e.g., from right to left according to the image width) based on a second transparency range. The second transparency range can be set to 0%-100%. The electronic device can adjust the transparency of the extended region corresponding to the top sub-region to the top sub-region along a third direction of the second dimension of the third image (e.g., from top to bottom according to the image height) based on the first transparency range to obtain a configured image. For example... Figure 14 As shown, the third region includes the extended area corresponding to the left sub-region extending to the left sub-region, the extended area corresponding to the right sub-region extending to the right sub-region, and the extended area corresponding to the top sub-region extending to the top sub-region. By adjusting the sharpness of the third region, the following can be obtained: Figure 14 The configuration image shown.

[0169] When the third region includes the extended regions corresponding to the left sub-region, the extended regions corresponding to the right sub-region, and the extended regions corresponding to the bottom sub-region, the electronic device can adjust the transparency of the extended regions corresponding to the left sub-region to the left sub-region along a first direction of the third image, based on a first transparency range. The electronic device can adjust the transparency of the extended regions corresponding to the right sub-region to the right sub-region along a second direction of the third image, based on a second transparency range. The electronic device can also adjust the transparency of the extended regions corresponding to the bottom sub-region to the bottom sub-region along a fourth direction of the second dimension of the third image (e.g., from bottom to top of the image height) based on the first transparency range to obtain a configured image. For example... Figure 15 As shown, the third region includes the extended area corresponding to the left sub-region extending to the left sub-region, the extended area corresponding to the right sub-region extending to the right sub-region, and the extended area corresponding to the bottom sub-region extending to the bottom sub-region. By adjusting the sharpness of the third region, the following can be obtained: Figure 15 The configuration image shown.

[0170] When the third region includes the extended regions corresponding to the left and right sub-regions, the extended regions corresponding to the right and right sub-regions, the extended regions corresponding to the top and top sub-regions, and the extended regions corresponding to the bottom and bottom sub-regions, the electronic device can adjust the transparency of the extended regions corresponding to the left sub-regions to the left sub-regions along a first direction of the third image, based on a first transparency range.

[0171] This embodiment of the application expands the wallpaper by using a first area and the first image by using a second area, ensuring that the size of the second image is equal to a preset size. Simultaneously, by adjusting the clarity of a third area of ​​the second image, splicing and mirroring artifacts in the configuration image are avoided, improving the imaging effect of the configuration image.

[0172] See Figure 17 The diagram shown is a partial timing illustration of a scenario with sufficient margin, provided in one embodiment of this application. In this embodiment, a scenario with sufficient margin can mean that the height of the image is greater than the height of the display screen, and the width of the image is greater than the width of the display screen. To avoid black borders appearing on the wallpaper displayed when the electronic device is in a screen-off state, in this embodiment, a scenario with sufficient margin can mean that the size of the wallpaper is greater than or equal to a preset size.

[0173] S1701, in response to a user's action to change the lock screen wallpaper, the control module in the electronic device adjusts the wallpaper size to a preset size.

[0174] In one embodiment of this application, to personalize wallpaper presentation, the electronic device can provide a wallpaper settings interface where users can perform user operations. For example, in the lock screen state, pinching the wallpaper with two fingers enters the wallpaper settings interface, which displays a lock screen wallpaper display area and related functional controls for editing the lock screen wallpaper. These functional controls may include application controls and image change controls. Application controls can be used to apply the editing operations already performed in the wallpaper settings interface. Image change controls can be used to change the current wallpaper to another image. Alternatively, users can also enter the wallpaper settings interface using any of the following operations: double-tap, long-press, swipe along a set trajectory, single-tap, or triple-tap.

[0175] In another embodiment, in response to a user's setting operation for the lock screen wallpaper, the control module in the electronic device can adjust the size of the wallpaper to a preset size.

[0176] In one embodiment of this application, the preset size can represent a preset multiple of the display screen size. The preset multiple can be set and adjusted according to actual needs; for example, the preset multiple can be set to 1.12. When the wallpaper size is greater than or equal to the preset size, the control module can crop an image with the preset size from the wallpaper as a configuration image. The method by which the control module obtains the configuration image from the wallpaper can be found in [reference needed]. Figure 5 Description of step S4012.

[0177] S1702, Get the changed wallpaper.

[0178] S1703, Construct image display resources.

[0179] In one embodiment of this application, in order for the view module to accurately display the wallpaper, the control module can call the ImageView component to adjust the display attributes of the changed wallpaper when constructing the image display resource. These display attributes may include, but are not limited to, the scaleType attribute and the alpha attribute. The scaleType attribute is used to set the scaling and cropping methods of the wallpaper, and the alpha attribute is used to set the transparency. When constructing the image display resource, the control module can also set the format of the changed wallpaper to a preset format. The preset format can be a non-bitmap format, for example, including but not limited to: Joint Photographic Experts Group (JPEG), Portable Network Graphics (PNG), or TagImage File Format (TIFF).

[0180] S1704, temporarily save the image to the cache.

[0181] In one embodiment of this application, the image in step S1704 can be... Figure 4 To reduce the number of image loading operations, the control module can send images to a cache for storage. When sending an image to the cache, the control module can also send the corresponding bitmap to the cache for storage.

[0182] S1705, Send a notification to the view module of the electronic device.

[0183] In one embodiment of this application, after an image is successfully stored in the cache, the control module can send a notification to the view module, which indicates that the image has been successfully stored in the cache.

[0184] See Figure 18 The image shown is a partial timing diagram of a zero-margin scene according to an embodiment of this application. In this embodiment, a zero-margin scene can mean that the height of the image is less than or equal to the height of the display screen, or the width of the image is less than or equal to the width of the display screen.

[0185] S1801, in response to a user operation to change the lock screen wallpaper, the control module in the electronic device obtains the changed wallpaper.

[0186] In one embodiment of this application, to personalize the wallpaper, the electronic device can provide a wallpaper settings interface, where the user can change and / or set the lock screen wallpaper. When the control module detects that the user has changed the lock screen wallpaper, it can obtain the changed wallpaper.

[0187] S1802, Construct image display resources.

[0188] In one embodiment of this application, the method by which the control module constructs image display resources can refer to... Figure 17 Description of step S1703.

[0189] S1803, construct map expansion resources and initialize map expansion nodes.

[0190] In one embodiment of this application, when constructing expanded image resources, the control module can convert images into bitmaps and set parameters required for expanded image creation based on user needs, such as expansion ratio and orientation.

[0191] In one embodiment of this application, the image expansion node encapsulates an algorithm for image expansion processing. Before calling the image expansion node to perform image expansion processing, the control module can initialize the image expansion node.

[0192] S1804 transmits data and callbacks to the mapping module in the electronic device.

[0193] In one embodiment of this application, when the control module transmits data to the image expansion module, it can send the storage path of the changed wallpaper and the parameters required for image expansion to the image expansion module.

[0194] In one embodiment of this application, after the control module generates a callback function, the callback function can be transmitted to the image expansion module, and the callback function can be registered in the image expansion module. The callback function of the image expansion module can execute a callback operation and enter the callback process. During the callback, the image obtained by the image expansion module can be sent back to the control module through callback data. Each callback can be considered as a consumption behavior in the producer-consumer model.

[0195] A producer-consumer pattern can be established between the control module and the image expansion module. The control module first initiates production by inputting the image's storage address into the image expansion module. This causes the expansion nodes in the expansion module to execute production asynchronously, starting an asynchronous, engineered image expansion process. After the expansion nodes complete their corresponding production operations (image processing operations), the generated images are then consumed (i.e., a callback occurs). This decouples the producer and consumer, resolving the issue of an overly close relationship between them and mitigating data blocking under high concurrency.

[0196] S1805, the image expansion module performs mirror image supplementation based on the first and second regions of the image.

[0197] In one embodiment of this application, the first region may include a left sub-region and a right sub-region of the image.
