Description

TECHNICAL FIELD

[0001] The present application relates to the terminal field, in particular to a method for displaying wallpaper and an electronic device. BACKGROUND

[0002] The wallpaper in the electronic device can generally reflect the aesthetic needs of the user; different wallpapers can be set based on the interests and hobbies of the user for different users to meet the personalized needs of the user for the display effect of the wallpaper. At present, the electronic device can provide some static wallpaper, dynamic wallpaper, etc. for the user to choose, the user can also use a photo or the like to customize the picture as the wallpaper, or apply the wallpaper template with the frame to use the customized picture as the display content in the frame.

[0003] However, the effect of the electronic device in displaying the same wallpaper before and after the screen rotation is still not good, which makes the user experience not good. SUMMARY

[0004] The present application provides a method for displaying wallpaper and an electronic device, which can adapt the wallpaper to the screen size and ensure the completeness of the content before and after the screen rotation of the electronic device, thereby improving the user experience.

[0005] In a first aspect, a method for displaying wallpaper is provided, applied to an electronic device, including: displaying a first display interface in a portrait screen state, the first display interface including a first wallpaper and at least one component, the first wallpaper including a first element; the size of the first wallpaper being the same as the screen size in the portrait screen state; detecting a rotation operation on the electronic device; in response to the rotation operation, displaying a second display interface in a landscape screen state, the second display interface including a second wallpaper and the component, the second wallpaper including the first element, wherein the second wallpaper is obtained by at least performing a picture filling processing on the first wallpaper, the size of the second wallpaper being the same as the screen size in the landscape screen state; the second wallpaper being different from the first wallpaper in a first display direction of the electronic device.

[0006] The electronic device of the present application embodiment can be a folding screen mobile phone, a tablet computer, etc.

[0007] It should be understood that the height of the second wallpaper after the picture filling processing is equal to the screen height in the landscape screen state, and the width of the second wallpaper after the picture filling processing is equal to the screen width in the landscape screen state.

[0008] In the present application embodiment, the second wallpaper after the picture filling processing can meet the requirements of the screen size in the landscape screen state. The size of the first element in the landscape screen state is reduced relative to the size of the first element in the portrait screen state.

[0009] In the embodiments of the present application, in the portrait screen state, the first wallpaper is vertical relative to the electronic device in the first display direction of the electronic device; and in the landscape screen state, the second wallpaper is horizontal relative to the electronic device in the second display direction of the electronic device.

[0010] In the embodiments of the present application, after the electronic device detects the rotation operation, the second wallpaper obtained by performing the image processing on the first wallpaper displayed before the rotation can be used for the landscape display after the rotation. Since the image processing is performed after the rotation, the size of the first element in the landscape screen state after the rotation is smaller than that in the portrait screen state, but the content is complete, and thus the second wallpaper displayed after the rotation is equivalent to including the first element content in the complete first wallpaper before the rotation, avoiding the problems of incomplete content display and content magnification caused by cropping in the related art. Therefore, by using the method for displaying the wallpaper provided in the embodiments of the present application, the wallpaper content can be displayed completely and reasonably, and the user experience is improved.

[0011] With reference to the first aspect, in some implementations of the first aspect, before displaying the first display interface in the portrait screen state, the method further includes: in response to an operation of applying the first wallpaper on the electronic device, applying the first wallpaper on the electronic device, and performing image processing on the first wallpaper to obtain and store the second wallpaper.

[0012] Exemplarily, the operation of applying the first wallpaper to the first display interface can be a click operation on the application control as shown in FIG. 1. Figure 22

[0013] In the embodiments of the present application, after the second wallpaper is stored, the second wallpaper can be directly called and displayed in the landscape screen state, thereby saving resources and improving efficiency.

[0014] With reference to the first aspect, in some implementations of the first aspect, performing image processing on the first wallpaper to obtain and store the second wallpaper includes: performing equal-ratio scaling processing on the first wallpaper to obtain a target wallpaper; performing the image processing on the target wallpaper to obtain and store the second wallpaper; wherein the height of the target wallpaper is less than or equal to the screen height in the landscape screen state; and the local content of the second wallpaper includes all the content of the target wallpaper.

[0015] In the embodiments of the present application, the height of the target wallpaper is less than or equal to the screen height in the landscape screen state, and the screen height in the landscape screen state is less than the screen height in the portrait screen state. Therefore, the height of the target wallpaper is less than the height of the first wallpaper, and thus it can be known that the target wallpaper is obtained by performing the first image processing on the first wallpaper, that is, the target wallpaper is obtained by performing the scaling processing on the first wallpaper.

[0016] ​In the embodiments of the present application, since the scaling processing is equal scaling, when the height of the target wallpaper after scaling processing is less than or equal to the height of the screen in the horizontal screen state, the width of the target wallpaper after scaling is naturally less than the width of the screen in the horizontal screen state. In this way, it can be ensured that the content of the wallpaper displayed after rotation includes the complete content of the wallpaper before rotation, avoiding the problems of incomplete content display and picture enlargement caused by cropping in the related art.

[0017] In combination with the first aspect, in some implementations of the first aspect, when the first wallpaper is a non-depth-of-field wallpaper, the scaling ratio in the equal scaling processing is a ratio of the height of the screen in the horizontal screen state to the width of the screen.

[0018] In the embodiments of the present application, for a non-depth-of-field wallpaper, since the scaling ratio is the height of the screen to the width of the screen in the horizontal screen state, the height of the screen is less than the width of the screen at this time, so that the size of the wallpaper after equal scaling processing is equivalent to being reduced, thereby realizing that the content of the wallpaper is reduced when displayed in the horizontal screen state.

[0019] In combination with the first aspect, in some implementations of the first aspect, when the first wallpaper is a depth-of-field wallpaper, the scaling ratio in the equal scaling processing is a ratio between a difference between the height of the screen in the horizontal screen state and a first distance, and a difference between the width of the screen in the horizontal screen state and the first distance.

[0020] In combination with the first aspect, in some implementations of the first aspect, the first distance is a distance from a top edge of the first element to a top edge of the screen.

[0021] It should be understood that the distance from the top edge of the first element to the top edge of the screen in the horizontal screen state is the same as the distance from the top edge of the first element to the top edge of the screen in the vertical screen state.

[0022] In the embodiments of the present application, for a depth-of-field wallpaper, when determining the scaling ratio, the first distance is removed, and the height of the first element in the depth-of-field wallpaper that is shielded to the first component before and after scaling will remain unchanged, thereby achieving the purpose of keeping the depth-of-field effect unchanged.

[0023] In combination with the first aspect, in some implementations of the first aspect, when the first wallpaper is a non-depth-of-field wallpaper, the picture supplementing processing includes: centering the target wallpaper with the width of the screen in the horizontal screen state as a reference; and supplementing pictures on the left and right sides of the target wallpaper.

[0024] In the embodiments of the present application, centering can ensure that the horizontal position of the wallpaper before and after screen rotation is unchanged, and the height of the non-depth-of-field wallpaper before and after screen rotation is the same as the height of the screen, so that no other picture supplementing is needed.

[0025] With reference to the first aspect, in some implementations of the first aspect, when the first wallpaper is a depth-of-field wallpaper, the supplemental image processing includes: centering the target wallpaper based on a screen width in a landscape state, and aligning a bottom edge of the target wallpaper with a screen bottom edge in the landscape state; and supplementing an upper portion and both sides of the target wallpaper.

[0026] In the embodiments of the present application, the distance between the first component and the screen top edge is unchanged before and after the screen rotation, and when the distance between the top edge of the first element in the depth-of-field wallpaper and the screen top edge is unchanged, the relative position between the first element and the first component is fixed. For example, the first element occludes the first component by a certain height, and when the distance between the top edge of the first element and the screen top edge is unchanged, the height of the occlusion of the first element to the first component before and after the rotation is unchanged. Therefore, when the scaling processing is performed, the distance between the top edge of the first element and the screen top edge can be removed in the scaling calculation, and the target wallpaper can be aligned with the screen bottom edge in the supplemental image processing. In this way, the position of the first element in the first wallpaper that occludes the first component is unchanged from the position of the first element in the second wallpaper that occludes the first component.

[0027] With reference to the first aspect, in some implementations of the first aspect, the first display interface and the second display interface are both lock screen interfaces or both desktops.

[0028] With reference to the first aspect, in some implementations of the first aspect, the at least one component includes one or more of weather information, sports information, health information, a date, a clock indicator, a font, a number, an image, music, or a video.

[0029] With reference to the first aspect, in some implementations of the first aspect, when the first wallpaper is a depth-of-field wallpaper, the first element is a foreground object identified from a custom picture.

[0030] For example, the foreground object is a person as shown in (a) of FIG. 1A and (a) of FIG. 1B. Figure 7 Figure 8

[0031] With reference to the first aspect, in some implementations of the first aspect, when the first wallpaper is a non-depth-of-field wallpaper, the first element is a custom picture.

[0032] With reference to the first aspect, in some implementations of the first aspect, when the first wallpaper is a template wallpaper, a template picture included in the template wallpaper is replaced by a custom picture.

[0033] In the embodiments of the present application, the custom picture can be a regular shape or an irregular shape.

[0034] ​​For example, a custom picture can be a picture in a first display area as shown in (a) of FIG. 10, or a mountain as shown in (a) of FIG. 11. Figure 16 Figure 17

[0043] In the embodiments of the present application, after the electronic device detects the rotation operation, the second wallpaper obtained by performing the image filling processing on the first wallpaper displayed before the rotation can be used for the horizontal screen display after the rotation. Since the image filling processing is performed after the rotation, the size of the first element in the horizontal screen state after the rotation is reduced relative to the size of the first element in the vertical screen state, but the content is complete, and then the second wallpaper displayed after the rotation is equivalent to including the first element content in the complete first wallpaper before the rotation, avoiding the problems of incomplete content display and content enlargement caused by cropping in the related art. Therefore, by using the method of displaying a wallpaper provided in the embodiments of the present application, the wallpaper content can be displayed completely and reasonably, and the user experience is improved.

[0068] In the embodiments of the present application, the terms "first", "second" and the like are used only for descriptive purposes, and cannot be construed as indicating or implying relative importance or an indicated number of the technical features. Thus, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0069] It should also be understood that the term "comprise" (also "comprises", "comprising", "includes" and / or "including") when used in this specification, specifies the presence of stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0070] In order to facilitate the understanding of the embodiments of the present application, first, the related terms involved in the embodiments of the present application are briefly described.

[0071] 1. Widget

[0072] A widget is an information carrier that provides some important or closely related information to the user in a condensed form for intuitive and quick display of information. The widget can be displayed in the display interface of the electronic device, such as the desktop or lock screen interface of the electronic device. The widget can include weather information, sports information, health information, date, clock indicator, artistic font, etc.

[0073] For example, the clock indicator for displaying time information can be displayed in the lock screen interface and the desktop. When the clock indicator is displayed in the desktop, the electronic device can switch to display the main interface corresponding to the clock application after the user clicks the clock indicator. Of course, a widget can provide information related to one application or information related to multiple applications. For another example, a widget in which the date and the clock indicator are combined can be displayed in the lock screen interface, and a widget in which the date, the clock indicator and the weather are combined can be displayed in the desktop.

[0074] The widget can be displayed in the form of a card, in the form of pure text, or in other forms, such as a clock indicator can be displayed in the form of a card, in the form of pure text, or in the form of a clock dial, and the embodiments of the present application do not make any limitation in this regard.

[0075] The content displayed in the widget includes, but is not limited to, text, numbers, images, music, and videos, and the embodiments of the present application do not make any limitation in this regard.

[0093] The wireless communication function of the electronic device 100 can be realized by the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor, and the baseband processor, etc.

[0094] The antenna 1 and the antenna 2 are used for transmitting and receiving electromagnetic wave signals. Each antenna in the electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas can also be multiplexed to improve the utilization rate of the antennas. For example: the antenna 1 can be multiplexed as a diversity antenna of a wireless local area network. In some other embodiments, the antenna can be used in combination with a tuning switch.

[0095] The electronic device 100 can realize the display function through the GPU, the display screen 194, and the application processor.

In some embodiments, the electronic device 100 can include 1 or N display screens 194, and N is a positive integer greater than 1.

[0098] For example, in the embodiments of the present application, the display screen 194 can display a lock screen wallpaper and a desktop wallpaper. The lock screen wallpaper displayed by the display screen can be a flat wallpaper or a depth-of-field wallpaper.

[0099] The electronic device 100 can realize the photographing function through an ISP, a camera 193, a video codec, a GPU, a display screen 194, and an application processor.

[0100] The ISP is used to process the data fed back by the camera 193. For example, when taking a photo, the shutter is opened, the light is transmitted to the camera photosensitive element through the camera, the light signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing to convert it into an image visible to the naked eye. The ISP can optimize the noise, brightness, and color of the image through an algorithm, and the ISP can also optimize the exposure and color temperature of the shooting scene and other parameters. In some embodiments, the ISP can be arranged in the camera 193.

The camera 193 can be triggered to start by application instructions, and the camera function can be implemented, such as capturing images of any scene. The camera 193 can include an imaging lens, a filter, an image sensor, and the like. Light emitted or reflected by an object enters the imaging lens, passes through the filter, and finally converges on the image sensor. The imaging lens is mainly used to converge the light emitted or reflected by all objects (may also be referred to as a scene to be photographed, a target scene, and can also be understood as a scene image that a user expects to capture) in the photographing angle of view into an image; the filter is mainly used to filter out excess light waves (for example, light waves other than visible light, such as infrared) in the light; and the image sensor can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The image sensor is mainly used to perform photoelectric conversion on the received light signal, convert the light signal into an electrical signal, and then transmit the electrical signal to an ISP to convert the electrical signal into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into a standard RGB, YUV, or the like image signal.

[0102] Exemplarily, the digital signal processor is used to process digital signals, and in addition to processing digital image signals, the digital signal processor can also process other digital signals. For example, when the electronic device 100 selects a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy, and the like.

[0103] Exemplarily, the video codec is used to compress or decompress digital videos. The electronic device 100 can support one or more video codecs. In this way, the electronic device 100 can play or record videos in multiple encoding formats, such as moving picture experts group (MPEG) 1, MPEG 2, MPEG 3, and MPEG 4.

[0104] Exemplarily, the gyroscope sensor 180B can be used to determine the motion posture of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 around three axes (i.e., the x-axis, the y-axis, and the z-axis) can be determined by the gyroscope sensor 180B. The gyroscope sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of shaking of the electronic device 100, calculates the distance that needs to be compensated by the lens module according to the angle, and lets the lens offset the shaking of the electronic device 100 by reverse movement, thereby achieving anti-shake. The gyroscope sensor 180B can also be used in scenarios such as navigation and motion sensing games.

[0105] Exemplarily, the acceleration sensor 180E can detect the magnitude of acceleration of the electronic device 100 in various directions (generally, x-axis, y-axis and z-axis). The magnitude and direction of gravity can be detected when the electronic device 100 is static. The acceleration sensor 180E can also be used to identify the posture of the electronic device 100 as an input parameter of the application program such as horizontal-vertical screen switching and pedometer.

[0106] Exemplarily, the distance sensor 180F is used to measure distance. The electronic device 100 can measure distance by infrared or laser. In some embodiments, for example in the scene shooting, the electronic device 100 can use the distance sensor 180F to measure distance to achieve fast focusing.

[0107] Exemplarily, the ambient light sensor 180L is used to perceive the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in the pocket to prevent false touch.

[0108] Exemplarily, the fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to realize functions such as unlocking, accessing application lock, taking pictures and answering incoming calls.

[0109] Exemplarily, the touch sensor 180K is also called touch device. The touch sensor 180K can be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also called touch screen. The touch sensor 180K is used to detect the touch operation acting on or near it. The touch sensor 180K can transmit the detected touch operation to the application processor to determine the touch event type. The visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be disposed on the surface of the electronic device 100, and disposed at a different position from the display screen 194.

[0110] The hardware system of the electronic device 100 is described in detail above, and the software system of the electronic device 100 is introduced below.

[0111] Figure 2 is a schematic diagram of the software system of the electronic device provided by the embodiments of the present application.

[0112] The layered architecture of the electronic device 100 divides software into several layers, each of which has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, the application layer, the application framework layer, the Android runtime and the system library, and the kernel layer.

[0113] The application layer can include a series of application packages.

[0114] As shown in Figure 2 , the application package can include lock screen, camera, gallery, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0115] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications of the application layer. The application framework layer includes some pre-defined functions.

[0116] As shown in Figure 2 , the application framework layer can include window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0117] The Android Runtime includes the core library and the virtual machine. The Android Runtime is responsible for the scheduling and management of the Android system.

[0118] The core library contains two parts: one is the function function that the java language needs to call, and the other is the core library of Android.

[0119] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the java files of the application layer and the application framework layer into binary files. The virtual machine is used to perform functions such as management of object life cycle, stack management, thread management, security and exception management, and garbage collection.

[0120] The system library can include a plurality of functional modules. For example: surface manager, media library, three-dimensional graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0121] The kernel layer is the layer between hardware and software. The kernel layer at least contains display driver, camera driver, audio driver, sensor driver, Wi-Fi driver, etc.

[0122] It should be noted that the electronic device mentioned in the embodiments of the present application can include more or less modules in the above-mentioned electronic device.

[0123] Taking a folding screen mobile phone including two display screens as an example, the two display screens are distributed on both sides of the folding axis. When the included angle between the two display screens is 0°, and the back surfaces (the side not used for display) of the two display screens are relatively attached together, the folding screen can be referred to as an outer folding screen, and this state can be referred to as a folded state of the outer folding screen. When the included angle between the two display screens is 180°, this state can be referred to as an unfolded state of the outer folding screen. In addition, the two display screens can be collectively referred to as outer screens of the outer folding screen. When the included angle between the two display screens is 0°, and the display surfaces (the side used for display) of the two display screens are relatively attached together, the folding screen can be referred to as an inner folding screen, and this state can be referred to as a folded state of the inner folding screen. When the included angle between the two display screens is 180°, this state can be referred to as an unfolded state of the inner folding screen. In addition, the two display screens can be collectively referred to as inner screens of the inner folding screen.

[0124] It should be understood that the number of display screens included in the folding screen is based on the folding axis around which the folding screen is folded as the reference line for dividing and naming the display screens. Here, the two display screens do not represent the actual panel structure of the folding screen. For example, the folding screen can be composed of two rigid panels and a hinge, and one of the two rigid panels can be referred to as a display screen. Alternatively, the folding screen is composed of a flexible panel and a hinge, and half of the flexible panel can be referred to as a display screen based on the hinge as the reference line. Here, the specific structure of the folding screen can be set as needed, and the embodiments of the present application do not make any limitation in this regard.

[0125] When the two display screens included in the folding screen mobile phone are distributed left and right along the folding axis, it can be indicated as a portrait screen state. When the two display screens included in the folding screen mobile phone are distributed up and down along the folding axis, it can be indicated as a landscape screen state. Then, the outer screens of the outer folding screen in the unfolded state and the inner screens of the inner folding screen in the unfolded state both include the portrait screen state and the landscape screen state. For the outer screens of the outer folding screen in the unfolded state, whether in the portrait screen state or the landscape screen state, when not unlocked, a lock screen interface is displayed; when successfully unlocked, a desktop is displayed. For the inner screens of the inner folding screen in the unfolded state, whether in the portrait screen state or the landscape screen state, when not unlocked, a lock screen interface is displayed; when successfully unlocked, a desktop is displayed.

[0126] I. Taking a depth-of-field wallpaper as an example for illustration

[0127] Figure 3 A schematic diagram of displaying a depth-of-field wallpaper on a folding screen mobile phone is shown.

[0128] Specifically, the depth-of-field wallpaper can be applied to the outer screen of the outer-fold folding screen in the unfolded state, or the inner screen of the inner-fold folding screen in the unfolded state; the depth-of-field wallpaper can be applied in the lock screen interface, or can also be applied in the desktop.

[0129] For example, as shown in (a) of FIG. 13, a depth-of-field wallpaper is displayed in the current lock screen interface, a foreground object 310 in the depth-of-field wallpaper is a person, and a background object 320 can indicate a framed area (such as the mountains and water in the oval frame) or can also indicate a framed area and an area filled with dot patterns outside the frame. The lock screen interface can also include a plurality of widgets, such as a clock indicator 330, a date 340, a lock screen control 350, a camera control 360, and the like. Figure 3

[0130] In the embodiment of the present application, the foreground object 310 is located above or in front of the clock indicator 330, and the background object 320 is located below or behind the clock indicator 330, so that the foreground object 310 and the background object 320 combined together can present a depth-of-field effect to form a depth-of-field wallpaper.

[0131] At present, whether it is the outer screen of the outer-fold folding screen in the unfolded state or the inner screen of the inner-fold folding screen, the screen is usually rectangular, and the sizes of two adjacent sides are different. For example, as shown in (a) of FIG. 14, the size of the outer screen of the outer-fold folding screen in the unfolded state is 1920*1080, and the size of the inner screen of the inner-fold folding screen in the unfolded state is 1080*1920. Figure 3 Figure 3 As shown in (a) of FIG. 14 and (b) of FIG. 15, when the electronic device is switched from a vertical screen state to a horizontal screen state, the size of the wallpaper changes. In order to maintain the same depth-of-field effect in the horizontal screen state and the vertical screen state, the related art processing method for such a wallpaper is to crop the depth-of-field wallpaper in the vertical screen state to adapt to the size of the wallpaper in the horizontal screen state, but this will cause the problem of incomplete content display, as shown in (b) of FIG. 15, the lower content of the foreground object 310 is cropped. Figure 3

[0132] For the background object 320 shown in (a) of FIG. 14, since the depth-of-field wallpaper is composed of a picture applied to a framed wallpaper template, when cropping, the lower content in the oval frame included in the background object 320 is also cropped, that is, the content of the foreground object 310 and the background object 320 after the cropping processing will together cause the problem of incomplete content display. If no cropping is performed, only scaling is performed, the wallpaper content will be stretched horizontally and compressed vertically, and the depth-of-field effect will be lost. Figure 3 Exemplarily,

[0133] is a schematic diagram of the size of a wallpaper displayed in a vertical screen state related to the related art, Figure 4 is a schematic diagram of the size of a wallpaper displayed in a horizontal screen state related to the related art. As shown in (a) of FIG. 14 and (b) of FIG. 15, when the electronic device is switched from a vertical screen state to a horizontal screen state, the size of the wallpaper changes. In order to maintain the same depth-of-field effect in the horizontal screen state and the vertical screen state, the related art processing method for such a wallpaper is to crop the depth-of-field wallpaper in the vertical screen state to adapt to the size of the wallpaper in the horizontal screen state, but this will cause the problem of incomplete content display, as shown in (b) of FIG. 15, the lower content of the foreground object 310 is cropped. Figure 5 Figure 4 ​​​​As shown, assuming that the screen has a vertical size of 2344px (pixel) and a horizontal size of 2156px, the size of the depth-of-field wallpaper displayed in the vertical screen state is 2156px*2344px; when the electronic device is switched from the vertical screen state to the horizontal screen state, as shown in FIG. 1B, the size of the depth-of-field wallpaper displayed in the horizontal screen state is 2344px*2156px. Figure 5 As shown, the size of the depth-of-field wallpaper needs to be enlarged based on 2344px, and then, in order to maintain the same depth-of-field effect in the horizontal screen state and the vertical screen state, the area beyond 2156px at the bottom needs to be cropped.

[0134] In combination with the wallpaper shown in (b) of FIG. 1C, it can be seen that, although the second wallpaper after cropping can adapt to the screen size in the horizontal screen state, the content at the bottom is not displayed completely, thereby resulting in poor user experience effect. Figure 3

[0135] Therefore, embodiments of the present application provide a method for displaying a wallpaper and an electronic device; in embodiments of the present application, after the electronic device detects a rotation operation, a target wallpaper corresponding to a first wallpaper displayed before rotation and after first image processing can be called, and a second wallpaper obtained after second image processing of the target wallpaper can be used for horizontal screen display after rotation; since the content of the wallpaper displayed after rotation includes the complete content of the wallpaper before rotation, the problem of incomplete content display caused by cropping in the related art is avoided, and therefore, by the method for displaying a wallpaper provided in embodiments of the present application, the complete content of the wallpaper can be displayed, thereby improving user experience.

[0136] Exemplarily, when the first wallpaper is a depth-of-field wallpaper, scaling is performed according to a preset ratio in the first image processing process, further ensuring that the position of the foreground object shielding the small component remains consistent with the position of the foreground object shielding the small component before rotation, thereby preserving the integrity of the content of the wallpaper while also preserving the depth-of-field effect.

[0137] Optionally, the method for displaying a wallpaper in embodiments of the present application can be applied to display of an electronic device; for example, the display of the electronic device includes but is not limited to: screen-off display of the electronic device, lock screen display of the electronic device, or desktop display of the electronic device, etc.; by the method for displaying a wallpaper in embodiments of the present application, after the electronic device detects a rotation operation of the electronic device by a user, a target wallpaper corresponding to the current wallpaper can be called, a second wallpaper can be obtained after processing of the target wallpaper, and the second wallpaper can be displayed in the display screen of the electronic device.

[0138] In the following, a method for displaying a depth-of-field wallpaper provided in embodiments of the present application is described in detail. Figure 6 to Figure 9 Exemplarily, as shown in (a) of FIG. 1D, the lock screen interface of the electronic device, and as shown in (b) of FIG. 1D, the wallpaper of the electronic device, are the same as (a) and (b) of FIG. 1C.

[0139] Figure 7 Figure 3 ​​​The lock screen interface shown in (a) is the same as that shown in (a) of FIG. 3; the wallpaper 300 displayed in the lock screen interface includes a foreground object 310, which can be a person, an animal, or the like; the foreground object 310 can be static or dynamic, which is not limited in the present application; the background object 320 is a framed area in a framed wallpaper template, or can also be the entire screen area; it should be understood that the partial framed area can indicate a first display area, and the first display area can be superimposed with a custom foreground object 310; the content in the framed area, such as the mountain, can be static, and the water can be dynamic, which is not limited in the present application; in other words, the lock screen interface can display a dynamic or static depth-of-field wallpaper, a depth-of-field wallpaper using a framed wallpaper template, or a depth-of-field wallpaper without a framed wallpaper template.

[0140] It should be understood that the above is an example of an application scenario of the depth-of-field wallpaper, and does not limit the application scenarios of the present application.

[0141] Figure 6 FIG. 4 is a schematic flowchart of a method for displaying a wallpaper according to an embodiment of the present application. The method 400 can be executed by the electronic device shown in FIG. 1; the method 400 includes steps S410 to S430, which are described in detail below. Figure 1

[0142] Step S410, display a first wallpaper in a portrait state.

[0143] Optionally, in a bright screen operation, the electronic device can display the first wallpaper in the portrait state.

[0144] For example, the bright screen operation is a click operation of the user on the power button of the electronic device; in response to the click operation, the electronic device switches from a black screen to a lock screen interface, and displays the first wallpaper in the lock screen interface.

[0145] It should be understood that the vertical edge of the screen is longer than the horizontal edge in the portrait state, and the horizontal edge of the screen is longer than the vertical edge in the landscape state.

[0146] In the present embodiment, the first wallpaper is a depth-of-field wallpaper.

[0147] Optionally, when the background object is a framed area in a framed wallpaper template, the first wallpaper is a depth-of-field wallpaper with a frame for the background object; when the background object is the entire screen area, the first wallpaper is a depth-of-field wallpaper without a frame; the first wallpaper can be a dynamic or static depth-of-field wallpaper. It should be understood that the dynamic depth-of-field wallpaper can include a wallpaper with a dynamic foreground object and / or a dynamic background object.

[0148] For example, the electronic device displays, in the portrait state, a lock screen interface as shown in FIG. 3(a), and the lock screen interface includes a depth-of-field wallpaper with a frame for the background object. Figure 7 ​The depth-of-field wallpaper shown in (a) has a background object 320 consisting of a framed area (such as an elliptical area) and an area outside the frame filled with a dotted pattern in a framed wallpaper template. In this example, the person in the foreground object 310 can be static, the mountain in the background object 320 can be static, while the water flow can be dynamic, and the dotted pattern can also be dynamic, such as the dotted pattern being blinking or scrolling.

[0149] For example, electronic devices displaying images in portrait mode, such as... Figure 8 The depth-of-field wallpaper shown in (a) has a background object 320 that is entirely filled with a dotted pattern. In this example, both the person in the foreground object 310 and the dotted pattern in the background object 320 are static.

[0150] Step S420: A rotation operation on the electronic device is detected.

[0151] For example, an inertial measurement unit in an electronic device can detect rotational operations on the electronic device.

[0152] The rotation operation is used to instruct the user to rotate the electronic device in physical space. For example, when the screen of the electronic device is perpendicular to the horizontal plane, the rotation operation can instruct the user to rotate the electronic device by 90° with an axis parallel to the horizontal plane and perpendicular to the screen as the rotation axis.

[0153] For example, such as Figure 7 (a) and Figure 7 As shown in (b) above, or, as in Figure 8 (a) and Figure 8 As shown in (b), the rotation operation can be an operation that rotates an electronic device from portrait mode to landscape mode.

[0154] Step S430: In response to the rotation operation, display the second wallpaper obtained by at least supplementing the first wallpaper in landscape mode.

[0155] Optionally, a second wallpaper obtained by performing a first image processing and a second image processing on the first wallpaper can be displayed.

[0156] In this embodiment, the second wallpaper is a depth-of-field wallpaper.

[0157] The second wallpaper is displayed in the same direction as the first wallpaper, so that the visual direction of the wallpaper displayed on the user's electronic device remains unchanged before and after rotation.

[0158] For example, such as Figure 7 (a) and Figure 7 As shown in (b) above, or, as in Figure 8 (a) and Figure 8As shown in (b) of FIG. 13, the display directions of the first wallpaper and the second wallpaper are both the X direction. It should be understood that, in the portrait screen state, the X direction is parallel to the axial direction of the folding axis of the electronic device; in the landscape screen state, the X direction is perpendicular to the axial direction of the folding axis of the electronic device.

[0159] Optionally, before the step S410, the method provided by the embodiment of the present application can further include:

[0160] In response to a click operation on the automatic rotation control, the automatic rotation function is opened.

[0161] The control center interface can be displayed in response to a sliding operation of the desktop from the edge of the screen, and the automatic rotation control can be included in the control center interface.

[0162] It should be understood that, when the automatic rotation function is opened, in step S430, in response to the rotation operation, the wallpaper displayed by the electronic device can be switched from the first wallpaper adapted to the portrait screen state to the second wallpaper adapted to the landscape screen state, otherwise, when the automatic rotation function is not opened, the first wallpaper will not be switched.

[0163] Optionally, Figure 9 Another flowchart for displaying the depth-of-field wallpaper is provided by the embodiment of the present application.

[0164] As Figure 9 shown, before the step S410, the method for displaying the depth-of-field wallpaper provided by the present application further includes:

[0165] S401, a lock screen wallpaper preview interface is displayed, and the lock screen wallpaper preview interface includes an application control.

[0166] In the preview area of the lock screen wallpaper preview interface, the first wallpaper is displayed correspondingly, and the first wallpaper is a depth-of-field wallpaper that can adapt to the inner screen or the outer screen in the portrait screen state.

[0167] As shown in (a) of FIG. 14, other contents of the lock screen wallpaper preview interface can be referred to the subsequent description of (b). Figure 21 Figure 21 The description of (b) is not repeated here.

[0168] S402, in response to a click operation on the application control, the first wallpaper is set as the wallpaper in the lock screen interface displayed by the electronic device in the portrait screen state.

[0169] S403, while S402 is executed, the first wallpaper is subjected to first image processing to obtain a target wallpaper.

[0170] S404, the target wallpaper is subjected to second image processing to obtain a second wallpaper.

[0171] ​The target wallpaper contains the same content as the first wallpaper; the second wallpaper includes the target wallpaper, and the second image processing differs from the first image processing.

[0172] Optionally, the target wallpaper may be a wallpaper obtained by the electronic device itself after performing a first image processing on the first wallpaper; or, the target wallpaper may refer to a wallpaper downloaded by the user through the electronic device, which is obtained by performing a first image processing on the first wallpaper; this application does not limit the source of the target wallpaper.

[0173] Optionally, the target wallpaper can be stored in the cache of the electronic device, or it can be stored on a cloud server and downloaded by the electronic device in response to a rotation operation. This application does not limit the storage of the target wallpaper. Of course, in actual processing, the target wallpaper may not be stored.

[0174] Optionally, the first image processing may include, but is not limited to: proportional scaling processing, wherein the height of the scaled wallpaper is less than or equal to the screen height in landscape mode.

[0175] It should be understood that after the first wallpaper is scaled proportionally, it can be ensured that the content of the first wallpaper is complete when the electronic device is displayed in landscape mode.

[0176] Optionally, combined Figure 20 As shown, when the user clicks the "Set as Lock Screen" control and sets the character as the foreground object 310 in the first wallpaper, or, in combination with... Figure 21 As shown, when the user clicks the application control to apply the first wallpaper, including the foreground object 310 and the background object 320, to the lock screen interface in portrait mode, the electronic device can perform first image processing on the first wallpaper and store the target wallpaper obtained after the first image processing in a cache location that corresponds to the first wallpaper.

[0177] Alternatively, the second wallpaper may be used only for display, or it may be stored in the cache of the electronic device and recalled when displayed.

[0178] It should be understood that, compared to performing first and second image processing on the first wallpaper after responding to a rotation operation, by performing first and second image processing on the first wallpaper simultaneously when clicking the "Set as Lock Screen" control or clicking the "Apply" control to apply the first wallpaper, and then obtaining and storing the second wallpaper, the second wallpaper can be directly called and displayed when needed, thus avoiding wasting the system resources of the electronic device.

[0179] Optionally, the second image processing may include, but is not limited to: centering the target wallpaper horizontally based on the screen size in landscape mode, and then performing image supplementation processing on the target wallpaper.

[0180] Exemplarily, the supplementary image processing can include, but is not limited to, copying or mirroring processing on partial content of the image, stretching processing on the image, and the like.

[0181] For example, when the first wallpaper is a depth-of-field wallpaper, which is divided into two layers of foreground objects and background objects, the target wallpaper after the first image processing also includes two layers of foreground objects and background objects, so that, when the second image processing is performed, the target wallpaper can be horizontally centered and arranged, and then the foreground objects and the background objects of the target wallpaper are processed in layers. The background objects can be processed by copying, mirroring, stretching, and the like, while the foreground objects can be processed by transparent supplementary image processing. In other words, the surrounding of the foreground objects is supplemented by transparent content, and only the layer in which the foreground objects are located needs to meet the size requirement of the horizontal screen state.

[0182] It should be understood that, after the supplementary image processing, the target wallpaper can meet the size requirement of the electronic device in the horizontal screen state while keeping the content of the target wallpaper unchanged.

[0183] It should be further understood that, when the background objects included in the target wallpaper are not background with a frame template, for example, the background is composed of pure color, lines, graphics, and the like, the above-mentioned supplementary image processing can be performed. If the background is a complex pattern or color, a network model, an AI algorithm, or the like can be used to learn appropriate supplementary image content for supplementary image processing, so as to ensure a natural transition of the content of the wallpaper. The specific learning method can be selected as required, and the embodiments of the present application do not limit the same.

[0184] In the embodiments of the present application, after the electronic device detects the rotation operation on the electronic device, the second wallpaper corresponding to the first wallpaper displayed before rotation can be called for display after rotation. Since the second wallpaper is obtained by performing first image processing on the first wallpaper to obtain a target wallpaper, and then performing second image processing on the target wallpaper, and since the target wallpaper and the first wallpaper include the same content and the second wallpaper includes the target wallpaper, the content of the second wallpaper displayed after rotation actually includes the content of the complete first wallpaper displayed before rotation, thereby avoiding the problem of incomplete content display caused by cropping in the related art. Therefore, by using the method for displaying a wallpaper provided in the embodiments of the present application, the content of the wallpaper can be displayed completely, thereby improving the user experience.

[0185] Optionally, as a first implementation manner, the first image processing can include scaling processing according to the ratio of the vertical edge size to the horizontal edge size of the electronic device in the vertical screen state.

[0186] It should be understood that the first wallpaper is scaled according to the ratio of the vertical to horizontal side dimensions of the electronic device in portrait mode. The vertical side dimension of the target wallpaper obtained after scaling is the same as the vertical side dimension of the electronic device in landscape mode.

[0187] For example, such as Figure 10 As shown in (a), the horizontal side of the electronic device in portrait mode is 2156px (also known as width), and the vertical side is 2344px (also known as height). Therefore, the size of the first wallpaper is 2156px × 2344px. By scaling the first wallpaper according to the ratio of the vertical side to the horizontal side of the electronic device in portrait mode, the vertical side of the first wallpaper can be changed from 2344px to 2156px, and the horizontal side can be changed from 2156px to 1983px. Thus, as shown in (a), the horizontal side of the first wallpaper is 2156px × 2344px. Figure 10 As shown in (b), the target wallpaper size is 1983px × 2156px.

[0188] Based on this, the required wallpaper size in landscape mode is determined to be 2344px × 2156px. Therefore, during the second image processing, after centering the target wallpaper horizontally, image supplementation can be performed on the left and right sides, increasing the horizontal size of the target wallpaper from 1983px to 2344px while ensuring the content is centered. Thus, as... Figure 10 As shown in (b), the dimensions of the second wallpaper are 2156px × 2344px.

[0189] Combination Figure 10 (a) and Figure 10 As shown in (b), since the difference between the vertical dimensions of the first wallpaper before scaling and the vertical dimensions of the target wallpaper after scaling (2344px and 2156px) is not significant, after scaling the first wallpaper, which is a depth-of-field wallpaper, in this way, the vertical dimensions of the foreground objects in the depth-of-field wallpaper change little, and the difference in the overlap height between the foreground objects and the widgets before and after scaling is also small and can be ignored.

[0190] Optionally, as a second possible implementation, before and after the rotation operation, the size of the widget on the screen is fixed, the distance between the widget and the top edge of the screen remains unchanged, and the first distance h1 between the top edge of the foreground object in the depth-of-field wallpaper and the top edge of the screen remains unchanged. Then, the first image processing can also perform proportional scaling processing according to a preset ratio. The preset ratio is the ratio of the first difference and the second difference. The first difference is the difference between the vertical dimension and the first distance h1 in portrait mode, and the second difference is the difference between the vertical dimension and the first distance h1 in landscape mode.

[0191] It should be understood that the distance between the widget and the top edge of the screen is unchanged before and after the screen rotation, and when the distance between the top edge of the foreground object in the depth-of-field wallpaper and the top edge of the screen is also unchanged, the relative position between the foreground object and the widget is fixed. For example, the foreground object occludes the widget by a certain height, and when the distance between the top edge of the foreground object and the top edge of the screen is unchanged, the height of the occlusion of the widget by the foreground object before and after the rotation can be unchanged, and thus, when the scaling processing is performed, the distance between the top edge of the foreground object and the top edge of the screen can be removed in the proportion calculation process.

[0192] In the embodiment, the widget can include a date component and a clock indicator.

[0193] For example, as shown in (a) of FIG. 13, the screen width of the electronic device in the portrait state is 2156px, and the screen height is 2344px, and thus the size of the first wallpaper is 2156px x 2344px. Assuming that the first distance h1 between the top edge of the foreground object and the top edge of the screen is 500px, the scaling ratio can be determined as (2156-500) / (2344-500)≈0.898, and after the scaling processing according to the ratio, as shown in (b) of FIG. 13, the size of the target wallpaper will be changed to 1936px x 2104px. Figure 11 Figure 11 On this basis, it can be determined that the wallpaper size requirement in the landscape state is 2344px x 2156px, and when the second image processing is performed, the target wallpaper can be horizontally centered and then bottom-aligned, that is, the bottom edge of the target wallpaper is aligned with the bottom edge of the screen in the landscape state, and then the top and left and right sides of the target wallpaper are supplemented, so that the horizontal size of the target wallpaper is increased from 1936px to 2344px, the vertical size of the target wallpaper is increased from 2104px to 2156px, and the content is complete and centered. As shown in (b) of FIG. 13, the size of the second wallpaper obtained is 2156px x 2344px.

[0194] On this basis, it can be determined that the wallpaper size requirement in the landscape state is 2344px x 2156px, and when the second image processing is performed, the target wallpaper can be horizontally centered and then bottom-aligned, that is, the bottom edge of the target wallpaper is aligned with the bottom edge of the screen in the landscape state, and then the top and left and right sides of the target wallpaper are supplemented, so that the horizontal size of the target wallpaper is increased from 1936px to 2344px, the vertical size of the target wallpaper is increased from 2104px to 2156px, and the content is complete and centered. As shown in (b) of FIG. 13, the size of the second wallpaper obtained is 2156px x 2344px. Figure 11

[0195] As shown in FIG. 13, because the first distance is removed when the scaling ratio is determined, the distance between the foreground object and the widget in the first wallpaper before scaling and the distance between the foreground object and the widget in the second wallpaper after scaling remain unchanged, so that the purpose of keeping the depth-of-field effect unchanged is achieved. Figure 11 The above is only an example of a first distance, and the embodiments of the present application are not limited thereto. Different scaling ratios can be determined in combination with the definition of different first distances, and then scaling processing can be performed according to different scaling ratios.

[0196]

[0197] ​​​It should be noted that, as shown in (b) of Figure 23 , if the wallpaper template applied by the user is the framed depth-of-field wallpaper template shown in style 2 or the unframed depth-of-field wallpaper template shown in style 3, the first distance between the top edge of the foreground object and the top edge of the screen is a fixed value. At this time, in the actual processing process, the electronic device can calculate the scaling ratio according to the fixed first distance in advance, and after the user clicks the application control, the scaling ratio is directly called for processing when the second wallpaper is determined according to the first wallpaper. As shown in Figure 22 , even if the wallpaper template applied by the user is the framed depth-of-field wallpaper template shown in style 2 or the unframed depth-of-field wallpaper template shown in style 3, the user adjusts the position of the foreground object and / or the position of the widget before clicking the application control. When the user clicks the application control, the electronic device can obtain the adjusted parameters of the user from the first wallpaper, and calculate the scaling ratio according to the adjusted parameters, and apply it to the process of determining the second wallpaper according to the first wallpaper.

[0198] In the embodiment of the present application, when the first wallpaper is a depth-of-field wallpaper, the method for displaying the wallpaper provided in the embodiment of the present application can ensure that the position of the foreground object after rotation that blocks the widget and the position of the foreground object before rotation that blocks the widget remain consistent in the first image processing process, thereby preserving the integrity of the wallpaper content while preserving the depth-of-field effect.

[0199] II. Take a non-depth-of-field wallpaper (ordinary wallpaper) as an example for description

[0200] Figure 12 A schematic diagram for displaying a non-depth-of-field wallpaper on a foldable screen phone is shown.

[0201] Specifically, the non-depth-of-field wallpaper can be applied to the outer screen of an outer-fold foldable screen in an unfolded state, or the inner screen of an inner-fold foldable screen in an unfolded state; the non-depth-of-field wallpaper can be applied in the lock screen interface, or also can be applied in the desktop.

[0202] For example, as shown in (a) of Figure 12 , a non-depth-of-field wallpaper is displayed in the current lock screen interface, the non-depth-of-field wallpaper includes a first display area 510, which can be used to display a picture customized by the user. Here, the first display area is a square area, of course, it can also be other shapes, and the present application does not limit this. The lock screen interface can also include a plurality of widgets, such as a clock indicator, a date, a lock screen control, a camera control, etc.

[0203] In the embodiments of the present application, the area of the lock screen interface other than the first display area can display the wallpaper template content of the electronic device, or can display preset content based on a wallpaper algorithm. For example, after the user selects a picture for display in the first display area, the area of the lock screen interface other than the first display area can be displayed with the dominant color in the picture as the fill color.

[0204] At present, whether it is the outer screen of the outer folding folding screen in the unfolded state or the inner screen of the inner folding folding screen, the screen is usually rectangular, and the sizes of the two adjacent sides are different. For example, Figure 12 (a) and Figure 12 (b) in FIG. 1, when the electronic device is switched from a portrait screen state to a landscape screen state, the wallpaper size is transformed, but no processing is performed on such a wallpaper in the related art, and the wallpaper is displayed in a center crop manner, resulting in that the entire wallpaper and the picture in the first display area are enlarged, thereby causing poor user experience effect.

[0205] Exemplarily, Figure 13 is a schematic diagram of a wallpaper size displayed in a portrait screen state related to the related art, Figure 14 is a schematic diagram of a wallpaper size displayed in a landscape screen state related to the related art. As shown in Figure 13 , assuming that the vertical size of the screen is 2344px and the horizontal size is 2156px, in the portrait screen state, the size of the first display area in the first wallpaper is assumed to be 1600px×1000px; when the electronic device is rotated from the portrait screen state to the landscape screen state, as shown in Figure 14 , the size of the first display area will be enlarged to 1739px×1087px with the center crop display of the wallpaper, that is, the picture size in the first display area in the second wallpaper is enlarged relative to the first wallpaper.

[0206] It can be known from the wallpaper shown in Figure 14 that although the enlarged second wallpaper can adapt to the screen size in the landscape screen state, the picture in the first display area is enlarged, thereby causing poor user experience effect.

[0207] In view of this, embodiments of this application provide a method for displaying wallpaper and an electronic device. In embodiments of this application, after the electronic device detects a rotation operation, a second wallpaper obtained by performing image supplementation processing on the first wallpaper displayed before rotation can be used for landscape display after rotation. Because image supplementation processing is performed after rotation, the size of the first element in the landscape state after rotation is reduced compared to the size of the first element in the portrait state, but the content is complete. Therefore, the second wallpaper displayed after rotation is equivalent to including the complete content of the first element in the first wallpaper before rotation, avoiding problems such as incomplete content display and enlarged content caused by cropping in related technologies. Thus, the method for displaying wallpaper provided by embodiments of this application can display wallpaper content completely and reasonably, improving the user experience.

[0208] For example, when the first wallpaper is a non-depth-of-field wallpaper, it can also be called a regular wallpaper. After processing by the method provided in this application embodiment, while adapting to the screen size in landscape mode, it can ensure that the image size in the displayed wallpaper is reasonable.

[0209] The following is combined Figure 15 to Figure 18 This application provides a detailed description of a method for displaying non-depth-of-field wallpapers.

[0210] For example, such as Figure 16 The lock screen interface of the electronic device shown in (a) is similar to... Figure 12 The lock screen interface shown in (a) is the same as the one in the previous example. This lock screen interface includes a first display area 510, which is the framed area in the framed wallpaper template. The first display area 510 can display an image with the content "mountain," or other custom images; this application does not limit this. The area before the first display area 510 is filled with a solid color. The content in the first display area can be static or dynamic; this application embodiment does not limit this. In other words, the lock screen interface can display dynamic or static ordinary wallpapers, ordinary wallpapers using framed or unframed wallpaper templates.

[0211] It should be understood that the above is an example of the application scenarios of ordinary wallpaper and does not limit the application scenarios of this application in any way.

[0212] Figure 15 This is a schematic flowchart illustrating a method for displaying wallpaper provided in an embodiment of this application. The method 600 can also be... Figure 1 The electronic device shown executes the method 600, which includes steps S610 to S650. Steps S610 to S650 are described in detail below.

[0213] Step S610: Display the first wallpaper in portrait mode.

[0214] Optionally, when the screen is on, the electronic device can display the first wallpaper in portrait mode.

[0215] For example, the screen-on operation is a user's click on the power button of an electronic device; in response to this click, the electronic device switches from a black screen to a lock screen, where the first wallpaper is displayed.

[0216] In this embodiment, the first wallpaper is a non-depth-of-field wallpaper.

[0217] Optionally, the first wallpaper can be a framed non-depth-of-field wallpaper or a frameless non-depth-of-field wallpaper. The first wallpaper can be a dynamic or static non-depth-of-field wallpaper.

[0218] For example, when an electronic device displays in portrait mode, such as Figure 16 In the non-depth-of-field wallpaper shown in (a), the content in the framed area (such as the first display area 510) of the framed non-depth-of-field wallpaper can be dynamic, while the area outside the frame filled with dotted patterns can be static.

[0219] For example, electronic devices displaying images in portrait mode... Figure 17 The non-depth-of-field wallpaper shown in (a) can have its image content (such as "mountain") in motion, while the areas filled with dotted patterns can be static.

[0220] Step S620: A rotation operation on the electronic device is detected.

[0221] For example, such as Figure 16 (a) and Figure 16 As shown in (b) above, or, as in Figure 17 (a) in Figure 17 As shown in (b), the rotation operation is an operation that allows an electronic device to be rotated from portrait mode to landscape mode.

[0222] Step S630: In response to the rotation operation, perform first image processing on the first non-depth-of-field wallpaper to obtain the target wallpaper.

[0223] Optionally, the target wallpaper may be a wallpaper obtained by the electronic device itself after performing a first image processing on the first non-depth-of-field wallpaper; or, the target wallpaper may refer to a wallpaper downloaded by the user through the electronic device, which is obtained by performing a first image processing on the first non-depth-of-field wallpaper; this application does not limit the source of the target wallpaper.

[0224] Optionally, the target wallpaper can be stored in a cache of the electronic device, or can be stored in a cloud server, and a download instruction is initiated by the electronic device in response to the rotation operation. The storage of the target wallpaper is not limited in the present application. Of course, the target wallpaper can also not be stored.

[0225] Optionally, the first image processing can include, but is not limited to, a scaling processing. The height of the wallpaper after the scaling processing is equal to the screen height in the horizontal screen state.

[0226] Optionally, the scaling ratio in the scaling processing can be a ratio of the screen height to the screen width in the horizontal screen state.

[0227] It should be understood that the first non-depth-of-field wallpaper is complete after the scaling processing, and the content of the wallpaper is guaranteed to be displayed in the horizontal screen state of the electronic device subsequently. Since the screen width in the horizontal screen state is larger than the screen height, when the height of the wallpaper after the scaling processing is equal to the screen height in the horizontal screen state, the width of the wallpaper after the scaling processing is also smaller than the screen width in the horizontal screen state. Therefore, the picture in the first display area of the target wallpaper is equivalent to being reduced in width and height.

[0228] Optionally, in combination with Figure 21 , when the user clicks the "set as lock screen" control and applies the picture to the first display area of the first non-depth-of-field wallpaper, or in combination with Figure 22 , when the user clicks the application control and applies the wallpaper including the picture in the first display area as the first non-depth-of-field wallpaper, the electronic device can perform the first image processing on the first non-depth-of-field wallpaper, and store the target wallpaper obtained after the first image processing in a cache location corresponding to the first non-depth-of-field wallpaper.

[0229] Step S640, performing second image processing on the target wallpaper to obtain a second non-depth-of-field wallpaper.

[0230] Step S650, displaying the second non-depth-of-field wallpaper in the horizontal screen state.

[0231] For example, the electronic device displays the second non-depth-of-field wallpaper with a frame as shown in (b) of Figure 16 , or displays the second non-depth-of-field wallpaper without a frame as shown in (b) of Figure 17 .

[0232] Optionally, the second non-depth-of-field wallpaper can be a wallpaper obtained by the electronic device itself performing second image processing on the target wallpaper; or the second non-depth-of-field wallpaper can be a wallpaper downloaded by the electronic device, which is obtained by performing the first image processing and the second image processing on the first non-depth-of-field wallpaper; the source of the second non-depth-of-field wallpaper is not limited in the present application.

[0233] Alternatively, the second non-depth-of-field wallpaper may be used only for display, or the second non-depth-of-field wallpaper may be stored in the cache of the electronic device and recalled when displayed.

[0234] It should be understood that, compared to performing first and second image processing on the first non-depth-of-field wallpaper after responding to a rotation operation, by performing first and second image processing on the first non-depth-of-field wallpaper simultaneously when clicking the set as lock screen control or clicking the application control to apply the first wallpaper, and obtaining and storing the second wallpaper, the second wallpaper can be directly called and displayed when needed, thus avoiding wasting the system resources of electronic devices.

[0235] Optionally, the second image processing may include, but is not limited to: after centering the target wallpaper horizontally based on the screen size in landscape mode, performing image supplementation processing on the left and right sides of the target wallpaper.

[0236] It should be understood that after the target wallpaper is processed, it can meet the size requirements when the electronic device is displayed in landscape mode, while ensuring that the content of the target wallpaper remains unchanged.

[0237] For example, such as Figure 18 As shown in (a), the screen height of the electronic device in landscape mode is 2156px and the screen width is 2344px. The size of the first non-depth-of-field wallpaper is 2156px × 2344px. The scaling ratio in the proportional scaling process is 2156px / 2344px ≈ 0.92. After scaling according to this ratio, as shown in (a), the screen height is 2156px and the screen width is 2344px. Figure 18 As shown in (b), the target wallpaper size will become 1984px × 2156px.

[0238] like Figure 18 As shown in (b), the target wallpaper's size does not meet the requirements for landscape mode. Therefore, a second image processing step is performed on the target wallpaper. First, the target wallpaper is centered based on the screen width in landscape mode. Then, the left and right sides of the target wallpaper are supplemented with additional images, thereby increasing the horizontal size of the target wallpaper from 1984px to 2344px. Thus, the size of the second wallpaper is 2156px × 2344px.

[0239] It should be noted that since the screen dimensions are fixed, in actual processing, electronic devices can pre-calculate the scaling ratio according to the screen dimensions. When the user clicks the application control and selects the second wallpaper based on the first wallpaper, the scaling ratio can be directly applied for processing.

[0240] In the embodiments of this application, after the electronic device detects a rotation operation on the electronic device, it can call the target wallpaper corresponding to the first non-depth-of-field wallpaper displayed before rotation, which has undergone the first image processing. Then, the second non-depth-of-field wallpaper obtained by the second image processing of the target wallpaper is used for display after rotation. Since the image included in the first non-depth-of-field wallpaper has undergone the first image processing along with the entire wallpaper, the height of the obtained target wallpaper is less than or equal to the screen height in landscape mode. The image in the target wallpaper is shrunk relative to the image in the first non-depth-of-field wallpaper, avoiding the problem of image magnification in related technologies. Therefore, the method of displaying wallpaper provided by the embodiments of this application can display the image in the wallpaper at an appropriate size, improving the user experience.

[0241] The following is combined with Figure 19 to Figure 24 This document provides an example description of the interface diagram and module interaction flow for setting wallpapers on electronic devices.

[0242] For example, such as Figure 19 As shown, Figure 19 The graphical user interface (GUI) shown in (a) is the desktop 701 of the electronic device; the electronic device detects that the user clicks on the control 702 of the gallery application on the desktop 701, such as... Figure 19 As shown in (b); when the electronic device detects that the user clicks on the control 702 of the Gallery application on the desktop 701, it displays as shown in (b); Figure 19 The gallery display interface shown in (c) is an image 703, which includes a person.

[0243] The electronic device detected a user clicking on image 703, such as... Figure 19 As shown in (d) in the image; after the electronic device detects the user's click on image 703, it displays as shown in the image. Figure 20 The image preview interface shown in (a) includes a share control, a favorite control, an edit control, a delete control, and more controls 705. The electronic device detects the user's click on the more controls 705, such as... Figure 20 As shown in (b) above; after the electronic device detects the user's click on the more controls 705, it displays as shown below. Figure 20 The display interface 706 shown in (c) is included in the display interface 706; the display interface 706 includes a display window 707; the display window 707 includes controls such as a set-to-control and a rotation control; the electronic device detects that the user clicks on a control in the display window 707, such as... Figure 20 As shown in (d) in the figure.

[0244] When the electronic device detects that the user has clicked "Set as Control" in display window 707, it displays as follows:Figure 21 The display interface 708 shown in (a) includes a wallpaper control 709, a partial always-on display control, and a contact control. The electronic device detects the user's tap on the wallpaper control 709, such as... Figure 21 As shown in (b) above; after the electronic device detects the user's click on the wallpaper control 709, it displays as shown in (b). Figure 21 The display interface 710 shown in (c) includes a menu card 711, which includes options for "Set as Lock Screen Control," "Set as Desktop Control," and "Set Control Simultaneously." The electronic device detects that the user clicks the "Set as Lock Screen Control" option in the menu card 711. Figure 21 As shown in (d) in the figure.

[0245] After the electronic device detects the user's click to set it as a lock screen control, it displays the following: Figure 22 The lock screen wallpaper preview interface shown in (a) includes a back control, an application control 712, an image change control, a lock screen style control, a depth-of-field effect control, and a preview area for displaying the lock screen interface. Here, since the image 703 selected by the user includes a person, in response to a click operation on the lock screen control, after recognizing that image 703 includes a person, the electronic device can present the person in image 703 with a depth-of-field effect in the preview area of ​​the lock screen wallpaper interface. That is, in the preview area of ​​the lock screen interface, the person in image 703 will be used as a foreground object, located in front of the widget, partially obscuring the widget. Additionally, a background object can be added to the preview area of ​​the lock screen interface, located behind the widget. The background object can be partially obscured by the widget, for example, in... Figure 22 In the preview area of ​​the lock screen interface shown, the mountains and water included in the elliptical area, and the area outside the elliptical area filled with dotted patterns, can be used as background objects.

[0246] The electronic device detects the user's click on the application control 712, such as... Figure 22 As shown in (b) of the document; when the electronic device detects that the user clicks on the application control 712, the electronic device can execute the wallpaper display method provided in this application embodiment. For example, based on the depth-of-field wallpaper in the portrait mode, a first image processing is performed on the depth-of-field wallpaper to generate a target wallpaper, and then a second image processing is performed on the target wallpaper to generate a second wallpaper and store it; in response to the rotation operation of the electronic device, the second wallpaper is called and displayed in the landscape mode.

[0247] For example, such as Figure 23 As shown, Figure 23The interface shown in (a) of FIG. 7A is another lock screen wallpaper preview interface. Since the picture selected by the user is a landscape picture, the depth-of-field effect is not enabled by default.

[0248] Here, the electronic device detects an operation of the user clicking the lock screen style control 713, as shown in (a) of FIG. 7B. Figure 23 After the electronic device detects the operation of the user clicking the lock screen style control 713, an interface as shown in (b) of FIG. 7B is displayed, in which a lock screen style menu is superimposedly displayed. The lock screen style menu can include a plurality of thumbnails indicating different lock screen styles, for example, style 1, style 2, and style 3, etc. Figure 23

[0249] It should be understood that the plurality of styles are wallpaper templates, and the user can select the wallpaper templates as needed. Style 1 can be a non-depth-of-field wallpaper template, in which the middle square region is used to display a template picture, which can be replaced by any custom picture in response to a click operation on the update picture control. Style 2 can be a depth-of-field wallpaper template, in which the middle oval region is used to display a template picture, which can be replaced by any custom picture in response to a click operation on the update picture control. Style 3 can be another depth-of-field wallpaper template, in which an irregular template picture can be displayed, which can be replaced by any custom picture in response to a click operation on the update picture control. Here, the foreground object identified by the template picture is equivalent to an irregular picture displayed.

[0250] The electronic device detects an operation of the user clicking the first thumbnail 714, as shown in (b) of FIG. 7C. Figure 23 After the electronic device detects the operation of the user clicking the first thumbnail 714, an interface as shown in (c) of FIG. 7C is displayed, which has the same layout as the lock screen wallpaper preview interface shown in (a) of FIG. 7A, and includes the same picture, but the presentation of the picture in the preview region of the lock screen interface is different in (c) of FIG. 7C. Figure 23 Figure 23 Figure 23 For example, the picture is displayed in a rectangular frame.

[0251] The electronic device detects an operation of the user clicking the application control 712, as shown in (a) of FIG. 7D. Figure 23 ​​​As shown in (d) in the figure, when the electronic device detects the operation of the user clicking the application control 712, the electronic device can perform the method for displaying a wallpaper provided in the embodiments of the present application, such as generating a target wallpaper by performing first image processing on the non-depth-of-field wallpaper in the portrait state, performing second image processing on the target wallpaper to generate a second non-depth-of-field wallpaper, and storing the second non-depth-of-field wallpaper; in response to the rotation operation of the electronic device, the second non-depth-of-field wallpaper is called and displayed in the landscape state.

[0252] It should be understood that the above is exemplified by taking the display interface for setting an image as a lock screen wallpaper in the electronic device; the method for displaying a wallpaper provided in the embodiments of the present application is also applicable to the screen-off display, desktop display, and the like of the electronic device; the present application does not limit this.

[0253] Exemplarily, as shown in (d) in the figure, in the embodiments of the present application, the process of displaying a wallpaper in the software architecture layer is as follows: Figure 24

[0254] S801, the gallery application can detect that the user sets a first wallpaper in a portrait state.

[0255] It should be understood that the process of setting a custom picture as the first wallpaper in the portrait state can refer to the description of the process of setting a custom picture as the first wallpaper in the portrait state, which will not be described herein again. Figure 19 to Figure 23

[0256] S802, in response to setting the custom wallpaper, the gallery application can notify the lock screen application that the wallpaper has changed through an access interface in the application framework layer, such as executing onWallpaperChanged.

[0257] S803, the lock screen application executes an update operation, such as executing postUpdateWallpaper.

[0258] S804, the lock screen application executes a running method of the lock screen wallpaper, such as executing the run method in LockscreenWallpaper.

[0259] At the same time of executing the running method of the lock screen wallpaper, the lock screen application starts an asynchronous task Async Task, and executes an “update wallpaper double cache method” in the result callback onPostExecute, such as executing the UpdateDoubleWallpaperCache method.

[0260] It should be understood that the lock screen wallpaper is the wallpaper in the lock screen interface. After the lock screen application executes the running method of the lock screen wallpaper, the lock screen interface displayed by the electronic device in the portrait state includes the first wallpaper, which is the lock screen wallpaper at this time.

[0261] ​​S805, the lock screen application calls the loadLandscapeCache method to load the cache mFullLandscapeDepthBgCache.

[0262] S806, the lock screen application determines whether the updated wallpaper belongs to a preset type of wallpaper.

[0263] For example, the lock screen application can determine that the updated wallpaper belongs to a framed depth-of-field wallpaper as shown in Figure 7 Figure 8 an unframed depth-of-field wallpaper as shown in Figure 16 a framed ordinary wallpaper as shown in Figure 17 an unframed ordinary wallpaper as shown in

[0264] S807, when it is determined that the updated wallpaper belongs to a preset type of wallpaper, the lock screen application notifies the hardware abstraction module to process the first wallpaper.

[0265] It should be noted that when it is determined that it does not belong to a preset type of wallpaper, the existing processing operation is performed. For example, as shown in (b) of Figure 23 the display interface, when it is determined that the updated wallpaper is an official wallpaper, it can be processed according to the existing corresponding mode (such as zooming and then cropping) to adapt to the size of the horizontal and vertical screens.

[0266] S808, the hardware abstraction module performs first image processing and second image processing on the first wallpaper, the first image processing being, for example, scaling processing, and the second image processing being, for example, patch processing, so that a second wallpaper adapted to the horizontal screen state can be obtained.

[0267] Optionally, when the lock screen application performs the changing operation in S803, the lock screen application can simultaneously determine whether the updated wallpaper belongs to a preset type of wallpaper. In addition, in order to facilitate subsequent scaling processing, the lock screen application can also obtain processing-related parameters in this process, such as determining a first distance from the top edge of the widget to the top edge of the screen in the vertical screen state, so as to facilitate subsequent determination of the scaling ratio based on the first distance.

[0268] S809, the hardware abstraction module delivers the processing result to the cache for storage, that is, the second wallpaper is stored as a cache.

[0269] For example, after calling the patch solution getShaderBitmap in the second image processing algorithm to obtain the Bitmap (i.e., the second wallpaper) after patching, the Bitmap is stored as a cache.

[0270] S810, the lock screen application displays the first wallpaper in the lock screen interface in the vertical screen state.

[0271] It should be understood that the display of the first wallpaper in the lock screen interface in the vertical screen state can refer to the display of the first wallpaper in the lock screen interface in the vertical screen state in the embodiments of the lock screen application.​Figure 7 (a) Figure 8 (a) Figure 16 (a) Figure 17 The description of the first wallpaper shown in (a) will not be repeated here.

[0272] S811, In response to the user's rotation operation on the electronic device, the lock screen application calls the cached Bitmap for display, that is, displays the second wallpaper in the lock screen interface in landscape mode.
