[0038] 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 belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. It is to be understood that the use of "a", "an", "the" and "at least one" herein are simply an antecedent basis upon which the open-ended claim or claims can be interpreted and thus "a", "an", "the" and "at least one" are used merely for convenience and to simplify presentation of the detailed description of the application. It is to be understood that the foregoing description is by way of example only, and is not intended to limit the application in any way. Indeed, various modifications and variations of the embodiments described herein will be apparent to those skilled in the art from considering this description, which is to be considered affirmative.

[0039] Wallpaper is an important carrier to present the overall visual style of a terminal product. When setting a wallpaper, a user usually selects a picture directly as the wallpaper, and the setting manner of the wallpaper is relatively single. The content of the lock screen wallpaper is the content in the picture, and no other elements outside the picture are included, so the lock screen wallpaper is relatively monotonous. In the process of setting the wallpaper, the user only needs to select a photo, and no other interaction with the terminal device is required, so the interaction based on the wallpaper is not rich enough, the user's participation in setting the wallpaper is poor, and the personalized setting of the wallpaper by the user cannot be met. In the related art, a wallpaper can be generated based on two pictures, but in the process of generating the wallpaper, the two pictures are simply superimposed, and the visual effect of the wallpaper obtained by superimposing is also poor.

[0040] To solve the technical problem that the setting manner of the wallpaper is relatively single, the human-computer interaction in the process of generating the wallpaper is not rich enough, the user's participation is poor, and the personalized setting of the wallpaper by the user cannot be met, the embodiments of the application provide a wallpaper setting method, which can determine a first image and a second image based on the selection of a user, increase the number of human-computer interactions in the process of generating the wallpaper, increase the user's participation, and meet the personalized setting of the wallpaper by the user. At the same time, the superimposition region is determined in the second image based on the target subject image of the first image, the size of the target subject image is the same as the size of the superimposition region, so that the target subject image can be perfectly superimposed with the superimposition region, a better superimposition effect can be presented, and a more aesthetic wallpaper can be obtained.

[0041] The wallpaper setting method provided by the embodiments of the present application is applied to a terminal device including a display screen. Exemplarily, the terminal device in the embodiments of the present application can be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an artificial intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, and / or a smart city device, and the like. The embodiments of the present application do not specially limit the specific form of the terminal device.

[0042] In order to better understand the embodiments of the present application, the wallpaper setting method provided by the embodiments of the present application will be described below with reference to the accompanying drawings. The following specific embodiments can be implemented independently, or can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments.

[0043] FIG. 1 is a flowchart of a wallpaper setting method provided by the embodiments of the present application. The wallpaper setting method is applied to a terminal device including a display screen. The order of the steps in the flowchart can be changed, and some steps can be omitted according to different needs. As shown in FIG. 1, the method includes:

[0044] In step S101, in response to a click on a synthetic wallpaper control, a wallpaper preview interface is displayed on the display screen.

[0045] The wallpaper preview interface can include a wallpaper selection control and a wallpaper application control. The synthetic wallpaper control is used to superimpose the picture selected by the user to generate a wallpaper. The synthetic wallpaper control can be represented by different names, such as a double exposure control, and the like, which are not limited herein. For example, the wallpaper can be generated based on a determined subject image and an overlay image. The subject image is an image used to determine a target subject, and the target subject can be obtained by subject extraction on the subject image. The overlay image is an image used to be superimposed on the target subject, and an overlay area used to be superimposed on the target subject can be determined from the overlay image, and the overlay area is used to be superimposed on the target subject.

[0046] In an embodiment of the present application, the synthetic wallpaper control can include thumbnails of preset wallpapers. The preset wallpaper is a preset synthetic picture that can be used as a wallpaper. The preset wallpaper includes a preset main picture and a preset overlay picture. The preset overlay picture is used to be overlaid on the preset main picture. After the terminal device receives a selection operation of the synthetic wallpaper control by the user, the terminal device can display a wallpaper preview interface of the synthetic wallpaper control on the terminal device, i.e., display the preset wallpaper. FIG. 2 is a schematic diagram of displaying a wallpaper preview interface in response to a click of a synthetic wallpaper control by a user according to an embodiment of the present application. As shown in (a) of FIG. 2, the terminal device can display a synthetic wallpaper control and other wallpaper options, such as a screen-off display option, a magazine lock screen option, and the like, on a wallpaper setting page. As shown in (b) of FIG. 2, in response to a selection operation of the synthetic wallpaper control by the user, the terminal device can display a wallpaper preview interface, which includes a preset wallpaper corresponding to the synthetic wallpaper control.

[0047] In an embodiment of the present application, the user can trigger a wallpaper setting instruction by performing a preset gesture action on the display screen. After the terminal device receives the wallpaper setting instruction, the terminal device displays a wallpaper setting page, which includes a synthetic wallpaper control. The gesture action can be set according to actual conditions, such as including a long press on a blank area on the home screen and selecting a preset option, such as selecting a "desktop and wallpaper option" option in a displayed pop-up window, to trigger the wallpaper setting instruction. For another example, the user performs a preset gesture action on the display screen, such as a double-hand pinch gesture, to trigger the wallpaper setting instruction. Alternatively, the user can enter a "settings" menu of the mobile phone and select a "desktop and wallpaper option" or a "display and brightness" option to trigger the wallpaper setting instruction. Alternatively, the user can trigger the wallpaper setting instruction by clicking a "settings" icon at the top of a notification bar, such as a pull-down notification bar, and selecting a "desktop and wallpaper option" option in an opened settings panel. Alternatively, the user can trigger the wallpaper setting instruction by opening an application list of the terminal device and selecting an application named "desktop and wallpaper option" or a similar name. Alternatively, the user can trigger the wallpaper setting instruction by opening a photo album or gallery application and selecting a setting wallpaper control corresponding to a target picture. The setting wallpaper control is used to set the target picture as a wallpaper.

[0048] In step S102, the terminal device displays a first option and a second option in response to a click operation of the wallpaper selection control.

[0049] In the embodiment of the present application, the wallpaper preview interface comprises a wallpaper selection control. The wallpaper selection control is used to select an image for generating a wallpaper, such as a subject image and an overlay image. In an embodiment of the present application, the wallpaper selection control can comprise a selection control, such as the "select wallpaper" control shown in (b) of FIG. 2. In another embodiment, the wallpaper selection control can further comprise a replacement control, such as the "replace picture" control shown in (b) of FIG. 2.

[0050] When the terminal device receives a click operation of the wallpaper selection control by the user, at least one first option and at least one second option are displayed on the wallpaper preview interface. The number of the displayed first options and second options is not limited in the embodiment of the present application. The first option is a reduced image corresponding to a recommended subject image. Each first option corresponds to a recommended subject image. The second option is a reduced image corresponding to a recommended overlay image. Each second option corresponds to a recommended overlay image. In an embodiment of the present application, the terminal device can display the first options and the second options through a wallpaper editing window. For example, when the terminal device receives a click operation of the wallpaper selection control by the user, a wallpaper editing window is displayed on the wallpaper preview interface, and the wallpaper editing window comprises the first options and the second options. FIG. 3 is a schematic diagram of displaying a wallpaper editing window according to an embodiment of the present application. As shown in (a) of FIG. 3, the wallpaper preview interface comprises a wallpaper selection control. As shown in (b) of FIG. 3, in response to the click of the wallpaper selection control by the user, a wallpaper editing window 30 is displayed on the wallpaper preview interface, and the wallpaper editing window 30 comprises three first options 301 and three second options 302. As shown in (b) of FIG. 3, each first option is a reduced image corresponding to a recommended subject image. Different first options correspond to different recommended subject images; and each second option is a reduced image corresponding to a recommended overlay image. Different second options correspond to different recommended overlay images.

[0051] In an embodiment of the present application, the recommended subject images and the recommended overlay images can be determined according to a preset recommendation rule. The recommendation rule can be set according to the needs of the user. For example, the recommendation rule can comprise determining the top three subject images in the official recommended images in terms of user usage rate as the recommended subject images, and determining the top three overlay images in the official recommended images in terms of user usage rate as the recommended overlay images, or the recommendation rule can comprise determining the latest image containing a subject taken by the user as the recommended subject image, and determining the latest image taken by the user as the recommended overlay image.

[0052] In an embodiment of the present application, when the terminal device receives a click operation on the wallpaper selection control, the first option and the second option are displayed, and the subject image replacement control is also displayed. The subject image replacement control is used to select a subject image for generating a wallpaper, as shown in (b) of FIG. 3. When a click operation on the subject image replacement control is received from the user, the gallery images are displayed on the wallpaper preview interface. If a selection operation on any of the displayed gallery images is received from the user, the any of the gallery images is determined as the subject image for generating a wallpaper. The gallery images are images stored in a gallery in the terminal device. In an embodiment of the present application, when a click operation on the subject image replacement control is received from the user, all the gallery images can be sequentially displayed on the wallpaper preview interface in the order of the time when the images are stored in the gallery. For example, the later the time when an image is stored in the gallery, the more front the position of the image on the wallpaper preview interface; the earlier the time when an image is stored in the gallery, the more back the position of the image on the wallpaper preview interface. In order to reduce the time spent by the user in searching for an image, the gallery images can be displayed according to the tags of the gallery images. In another embodiment of the present application, when a click operation on the subject image replacement control is received from the user, the gallery images to be displayed on the wallpaper preview interface can be determined based on the tags of the gallery images and a preset display rule. The tags of the gallery images are used to classify the images, for example, people, selected, landscape, animals, buildings, etc. The display rule is used to determine the type of images to be displayed on the wallpaper preview interface after the user clicks the subject image replacement option. The display rule can be set according to the user's needs, for example, the gallery images with the tag of people are displayed after the user clicks the subject image replacement option, or the gallery images with the tag of selected are displayed after the user clicks the subject image replacement option. The images with the tag of selected can be official recommended images, or can be images suitable for being subject images after intelligent recognition.

[0053] Figure 4 is a schematic diagram of displaying a gallery image in response to a click on a subject changing graphical control according to an embodiment of the present application. As shown in Figure 4, when the terminal device receives a click operation of a user on a subject changing option, the gallery image with a label of a person is displayed on the wallpaper preview interface, as shown in (a) to (b) of Figure 4. Based on the label, the corresponding image is displayed, which can avoid displaying images of various categories on the wallpaper preview interface, so that the user can quickly locate the first image. By selecting the label, the user can quickly determine the first image from the specified category. In an embodiment, the wallpaper preview interface further includes at least one label of other images in the gallery, such as a selected label, a landscape label, a building label, etc. When the terminal device receives a selection operation of a user on any label, the image corresponding to the any label is displayed on the wallpaper setting page. For example, as shown in (b) of Figure 4, the image with a label of a person in the gallery is displayed on the wallpaper setting page. When the terminal device receives a selection operation of a user on a label representing an animal, the image with a label of a person in the gallery is stopped from being displayed on the wallpaper setting page, and the image with a label of an animal in the gallery is displayed. The above embodiment can modify the type of images displayed on the wallpaper preview interface by switching the label. In an embodiment, when the terminal device receives a cancel operation of a user on the currently selected label, all types of images can be displayed on the wallpaper setting page. For example, as shown in (b) of Figure 4, the currently selected label is a person. When the user performs a cancel operation on the label representing a person, such as clicking on the label picture of a person, and the user does not select other labels, all types of images can be displayed on the wallpaper setting page. All types of images can be displayed according to the time of storage in the gallery. For example, the later the time of storage in the gallery, the closer to the front position on the wallpaper preview interface; the earlier the time of storage in the gallery, the closer to the rear position on the wallpaper preview interface.

[0054] In an embodiment of the present application, after displaying the gallery image on the wallpaper preview interface, the user can perform a preset action on the display area of the gallery image to change the image content displayed on the wallpaper preview interface. For example, the user can perform a downward sliding operation on the display area of the gallery image, and the current display interface displays the gallery image that has not been displayed by sliding the display area downward. Or the user can perform an upward sliding operation on the display area of the gallery image, and the current display interface displays the gallery image that has been displayed by sliding the display area upward.

[0055] Step S103, when the terminal device receives a selection operation on the first option, determining the first image.

[0056] In an embodiment of the present application, when receiving the selection operation of the user on any first option, the recommended subject image corresponding to the any first option is determined as the target subject image for generating the wallpaper, i.e., the recommended subject image corresponding to the any first option is determined as the first image. In an embodiment of the present application, after the terminal device receives the click operation on the wallpaper selection control and displays the first options, as shown in (b) of FIG. 3, the thumbnail of the preset subject image corresponding to the preset wallpaper is selected by default in the displayed at least one first option.

[0057] In an embodiment of the present application, if receiving the selection operation of the user on any displayed gallery image, the any gallery image is determined as the subject image for generating the wallpaper, and the first control is updated according to the any gallery image, so that the first control after the update includes the reduced image corresponding to the any gallery image. After the update of the first control, the first control corresponding to the any gallery image is in the selected state. In this embodiment, the selection operation of the user on any displayed gallery image is equivalent to the selection operation on the first option, and if receiving the selection operation of the user on any displayed gallery image, the any gallery image is determined as the first image.

[0058] In an embodiment of the present application, when the terminal device receives the selection operation on the first option, the second option is updated based on the selected first option and the preset matching rule, so that the updated second option matches the selected first option. FIG. 5 is a schematic diagram of updating the second option based on the selection operation on the first option according to an embodiment of the present application. As shown in (a) of FIG. 5, the pre-selected first option is the first option corresponding to the girl thumbnail. As shown in (a) to (b) of FIG. 5, when the terminal device receives the selection operation of the user on the first option corresponding to the man thumbnail, the second option is updated, and the updated second option and the second option before the update include different recommended superimposed images. The above embodiment updates the second option based on the selected first option, so that the updated second option is more matched with the selected first option, and the user can more conveniently select the recommended superimposed image more matched with the selected recommended subject image.

[0059] In an embodiment of the present application, the matching rule can include a primary color matching rule. Each picture has its corresponding primary color. The primary color of a picture refers to the color that occupies a dominant position or appears most frequently in the picture, and is the color that is most salient and important in the entire picture, and can be used to represent the overall color tone and style of the picture. The primary color matching rule can include a correspondence relationship between different primary colors. One of the primary colors can correspond to one or more other primary colors. A first primary color corresponding to the selected first option can be determined; based on the primary color matching rule, a second primary color corresponding to the first primary color is determined, and one first primary color can correspond to one or more second primary colors; based on the determined second primary color, at least one superimposed recommendation picture is determined; and the second option is updated according to the superimposed recommendation picture, so that the primary color of the updated second option matches the primary color of the selected first option. The primary color of the superimposed recommendation picture is the second primary color. In an embodiment of the present application, the first image gallery can be searched based on the determined second primary color, and the images in the first image gallery whose primary color is the second primary color are determined as the second image gallery. The first image gallery can be an image gallery storing official recommended pictures, or an image gallery storing all pictures of the terminal device. If multiple second primary colors are determined, one superimposed recommendation picture can be determined for each second primary color, thereby obtaining multiple superimposed recommendation pictures. If one second primary color is determined, multiple superimposed recommendation pictures whose primary color is the second primary color can be determined based on the second primary color, thereby obtaining multiple superimposed recommendation pictures. In an embodiment of the present application, the primary color of an image can be determined based on an image editing software, an online color palette tool, or a color analysis tool. The above embodiment determines the superimposed recommendation picture that matches the selected first option based on the primary color matching rule, so that the determined superimposed recommendation picture matches the selected first option in color, and thus the user can more conveniently select a target superimposed picture that matches the color of the selected recommended primary picture.

[0060] In an embodiment of the present application, the matching rule can include an information matching rule. After the selection operation on the first option is performed, the shooting information of the recommended subject image corresponding to the selected first option, such as shooting time, shooting location and the like, can be determined, and the superimposed recommended image matching the shooting information can be determined; the second option displayed on the wallpaper preview interface can be updated according to the superimposed recommended image, so that the shooting information of the recommended superimposed image corresponding to the updated second option matches the shooting information of the recommended subject image corresponding to the selected first option. In an embodiment of the present application, the second gallery of the terminal device can be searched based on the determined shooting information, and the image in the second gallery matching the shooting information can be determined as the superimposed recommended image. The second gallery can be a gallery storing pictures taken by the user, or a gallery storing all pictures of the terminal device. For example, when the shooting time of an image in the second gallery is the same as the shooting time of the picture corresponding to the selected first option, and / or the shooting location of the image is the same as the shooting location of the picture corresponding to the currently selected first option, the image is determined as the superimposed recommended image matching the shooting information of the first option. In the above embodiment, the superimposed recommended image matching the selected first option is determined based on the information matching rule, so that the determined superimposed recommended image matches the selected first option in shooting information, and thus the user can more conveniently select the target superimposed image matching the selected recommended subject image in shooting information.

[0061] In an embodiment of the present application, the superimposed recommended image can be determined based on the primary color matching rule and the information matching rule simultaneously, and the second option can be updated according to the determined superimposed recommended image, so that the updated second option includes the second option matching the first primary color of the selected first option, and the second option matching the shooting information of the selected second option.

[0062] In step S104, the subject of the first image is extracted to obtain a target subject image, and the target subject image is displayed on the wallpaper preview interface.

[0063] In an embodiment of the present application, the subject can refer to the most eye-catching, most focused part or object in the image, which can include a person, an object, a scene, a detail. For example, the person can include a single person, multiple persons. The object can include a car, a building, food, an animal, etc. The scene can include a mountain, a beach, a forest. The detail can refer to a local part with a specific meaning, which can be a flower, an eye, a palm, etc. Through the subject extraction manner, the subject in the image can be extracted. The target subject image is a partial image corresponding to the subject in the first image. FIG. 6 is a schematic diagram of subject extraction provided by an embodiment of the present application. (a) in FIG. 6 is a first image, which includes a girl, a white cloud and a tree. The subject in the first image is the girl. The target subject image shown in (b) in FIG. 6, i.e., the partial image corresponding to the girl in (a) in FIG. 6, can be obtained by subject extraction on the first image shown in (a) in FIG. 6.

[0064] In an embodiment of the present application, the subject can refer to the most eye-catching, most focused part or object in the image, which can include a person, an object, a scene, a detail. For example, the person can include a single person, multiple persons. The object can include a car, a building, food, an animal, etc. The scene can include a mountain, a beach, a forest. The detail can refer to a local part with a specific meaning, which can be a flower, an eye, a palm, etc. Through the subject extraction manner, the subject in the image can be extracted. The target subject image is a partial image corresponding to the subject in the first image. FIG. 6 is a schematic diagram of subject extraction provided by an embodiment of the present application. (a) in FIG. 6 is a first image, which includes a girl, a white cloud and a tree. The subject in the first image is the girl. The target subject image shown in (b) in FIG. 6, i.e., the partial image corresponding to the girl in (a) in FIG. 6, can be obtained by subject extraction on the first image shown in (a) in FIG. 6.

[0065] In an embodiment of the present application, the target subject image is displayed on the wallpaper preview interface, including: determining an overlay area in a preset overlay based on the target subject image, the overlay area having the same size as the target subject image; generating a target image according to the target subject image and the determined overlay area, and displaying the generated target image on the wallpaper preview interface. FIG. 7 is a schematic diagram of determining an overlay area in an overlay according to a target subject image in an embodiment of the present application. As shown in (a) of FIG. 7, it is a preset overlay. As shown in (b) and (c) of FIG. 7, an overlay area is determined in the preset overlay based on the image contour of the target subject image, and the overlay area has the same size as the target subject image. In an embodiment of the present application, a region having the same size as the target subject image can be determined in any region of the preset overlay, and the region is determined as the overlay area. In an embodiment of the present application, a region having the same size as the target subject image can be determined in a region rich in color in the preset overlay, and the region is determined as the overlay area. For example, a region having the same size as the target subject image can be determined in an image region in which the color variance of the region pixels in the preset overlay is greater than a preset variance threshold, and the region is determined as the overlay area. This method can make the overlay area have richer colors and improve the visual experience. In an embodiment of the present application, the way of determining the overlay area is not limited in any way.

[0066] In an embodiment of the present application, when the terminal device receives a click operation on the wallpaper selection control, the first option displayed includes a thumbnail of a preset subject image corresponding to the preset wallpaper, and the second option displayed includes a thumbnail of a preset overlay image corresponding to the preset wallpaper. After the second option is displayed, as shown in (b) of FIG. 3, the thumbnail of the preset subject image is selected by default. If the determined first image is inconsistent with the preset subject image and the currently selected second option is not the thumbnail of the preset overlay image, the first image is subjected to subject extraction to obtain a target subject image, an overlay region is determined in the preset overlay image based on the target subject image, the size of the overlay region is the same as that of the target subject image, a target image is generated according to the target subject image and the determined overlay region, and the generated target image is displayed on the wallpaper preview interface. If the determined first image is consistent with the preset subject image and the image corresponding to the currently selected second option is not the thumbnail of the preset overlay image, the first image is subjected to subject extraction to obtain a target subject image, an overlay region is determined in the image corresponding to the currently selected second option based on the target subject image, the size of the determined overlay region is the same as that of the target subject image, a target image is generated according to the target subject image and the determined overlay region, and the generated target image is displayed on the wallpaper preview interface. If the determined first image is consistent with the preset subject image and the image corresponding to the currently selected second option is the thumbnail of the preset overlay image, the currently displayed wallpaper on the wallpaper preview interface is not adjusted, i.e., the preset wallpaper displayed on the wallpaper preview interface is not adjusted, and the currently displayed wallpaper is continuously displayed. The above embodiment can determine that the subject part of the wallpaper generated based on the first image has not changed compared with the subject part of the currently displayed wallpaper, i.e., one or more of the outline, size, and content of the subject part has not changed, when the first image has not changed compared with the preset subject image, and the currently displayed wallpaper is not adjusted, thereby avoiding waste of computing power.

[0067] In step S105, when the terminal device receives a selection operation on the second option, a second image is determined, and an overlay region is determined in the second image based on the target subject image.

[0068] In an embodiment of the present application, when a selection operation of any second option by a user is received, a recommended overlay image corresponding to the any second option is determined as a target overlay image for generating a wallpaper, i.e., the recommended overlay image corresponding to the any second option is determined as a second image. In an embodiment of the present application, after the terminal device displays the second option upon receiving a click operation on the wallpaper selection control, as shown in (b) of FIG. 3, the thumbnail of the preset overlay image corresponding to the preset wallpaper is selected by default in the at least one displayed second option.

[0069] In an embodiment of the present application, when the terminal device receives a click operation on the wallpaper selection control, the first option and the second option are displayed, and a change superimposed image control is also displayed. The change superimposed image control is used to select a superimposed image for generating a wallpaper, as shown in (b) of FIG. 3. When a click operation on the change superimposed image control is received from the user, a gallery image is displayed on the wallpaper preview interface; if a selection operation on any gallery image displayed is received from the user, the any gallery image is determined as the superimposed image for generating a wallpaper. The gallery image is an image stored in a gallery in the terminal device. In an embodiment of the present application, when a click operation on the change superimposed image control is received from the user, all gallery images can be displayed in order on the wallpaper preview interface according to the time sequence in which the images are stored in the gallery. For example, the later the time at which an image is stored in the gallery, the more forward the position at which the image is displayed on the wallpaper preview interface; the earlier the time at which an image is stored in the gallery, the more backward the position at which the image is displayed on the wallpaper preview interface. In order to reduce the time spent by the user in searching for an image, the gallery images can be displayed according to their tags, and in another embodiment of the present application, when a click operation on the change superimposed image control is received from the user, the gallery images that need to be displayed on the wallpaper preview interface can be determined based on the tags of the gallery images and a preset display rule. The tag of a gallery image is used to classify the image, for example, a person, a selection, a landscape, an animal, a building, etc. The display rule is used to determine the type of image displayed on the wallpaper preview interface after the user clicks the change superimposed image option. The display rule can be set according to user demand, for example, the gallery images with a landscape tag are displayed after the user clicks the change superimposed image option, or for example, the gallery images with a selection tag are displayed after the user clicks the change superimposed image option. The image with a selection tag can be an officially recommended image, or can be an image that is suitable for superimposition after intelligent recognition.

[0070] Figure 8 is a schematic diagram illustrating displaying a gallery image in response to a click on a replace overlay control according to an embodiment of the present application. As shown in Figure 8, when the terminal device receives a click operation on the replace overlay option, the gallery image with the label of landscape is displayed on the wallpaper preview interface, as shown in (a) to (b) of Figure 8. Displaying the corresponding image based on the label can avoid displaying a large number of images of different categories on the wallpaper preview interface, which makes it difficult for the user to quickly locate the first image. The user can quickly determine the first image from the specified category by selecting the label. In an embodiment, the wallpaper preview interface further includes at least one label corresponding to other images in the gallery, such as the labels of selected, landscape, and building. When the terminal device receives a selection operation on any label, the images corresponding to the any label are displayed on the wallpaper setting page. For example, as shown in (b) of Figure 8, the images with the label of landscape in the gallery are displayed on the wallpaper setting page. When the terminal device receives a selection operation on the label representing the building, the images with the label of landscape in the gallery are stopped from being displayed on the wallpaper setting page, and the images with the label of building in the gallery are displayed. The above embodiment can modify the types of images displayed on the wallpaper preview interface by switching the labels. In an embodiment, when the terminal device receives a cancel operation on the currently selected label, all types of images can be displayed on the wallpaper setting page. For example, as shown in (b) of Figure 8, the currently selected label is landscape. When the user performs a cancel operation on the label representing the landscape, such as clicking the label image of the landscape, and the user does not select other labels, all types of images can be displayed on the wallpaper setting page. All types of images can be displayed according to the time of storage in the gallery. For example, the later the time of storage in the gallery, the closer to the front position on the wallpaper preview interface; the earlier the time of storage in the gallery, the closer to the rear position on the wallpaper preview interface.

[0071] In an embodiment of the present application, after the second image is determined, an overlay area is determined in the second image based on the target subject image, the size of the determined overlay area in the second image is the same as the size of the target subject image; a target image is generated according to the target subject image and the determined overlay area, and the generated target image is displayed on the wallpaper preview interface. In an embodiment of the present application, if the determined second image is inconsistent with the preset overlay image, the overlay area is determined in the second image based on the target subject image; if the preset subject image is consistent with the target subject image, the currently displayed wallpaper is not adjusted, such as the preset wallpaper is not adjusted, and the currently displayed wallpaper is continuously displayed. The above embodiment can determine that the overlay part of the wallpaper generated based on the second image has not changed compared with the overlay part of the currently displayed wallpaper when the second image has not changed compared with the preset overlay image, such as the content contained in the overlay part has not changed, the currently displayed wallpaper is not adjusted, thereby avoiding the waste of computing power. For specific embodiments of determining the overlay area in the second image based on the target subject image, reference can be made to the related description in the foregoing, such as the related description of determining the overlay area in the preset overlay image based on the target subject image in the foregoing.

[0072] In an embodiment of the present application, after the overlay area in the second image is determined based on the target subject image, the other areas outside the overlay area in the second image can be cropped, so that the cropped second image only contains the overlay area; the transparency of the other areas outside the overlay area in the second image can also be set to 0%, so that the other areas are invisible.

[0073] In some embodiments of the present application, in order to automatically update the displayed wallpaper, a plurality of second images can be determined based on the user's selection. For example, a plurality of overlay image options can be displayed on the wallpaper preview interface, and a plurality of second images can be determined based on the user's selection in response to the user's click operation on the plurality of overlay image options. The overlay area can be determined in each second image determined by the user based on the target subject image.

[0074] In step S106, a target image is generated according to the target subject image and the overlay area, and the target image is displayed.

[0075] In an embodiment of the present application, the target subject image and the overlay area can be overlaid based on the overlay range to generate a target image. The overlay range can be set according to actual conditions. The larger the overlay range is, the more visible parts in the overlay area are; the smaller the overlay range is, the fewer visible parts in the overlay area are. The visible part and the invisible part in the overlay area can be determined based on the overlay range. The transparency of the overlay area is set based on the determined visible part and invisible part; the overlay area with the set transparency is overlaid on the target subject image to generate a target image.

[0076] In some embodiments of the present application, the visible part and the invisible part in the superimposition region can be determined according to the width of the superimposition region and the superimposition range. For example, the superimposition region can be divided into an upper half and a lower half according to the width of the superimposition region and the superimposition range, the upper half can be set as the visible part and the lower half can be set as the invisible part, or the upper half can be set as the invisible part and the lower half can be set as the visible part. In some embodiments, the ratio of the invisible part to the visible part can be determined based on the superimposition range. For example, when the superimposition range is 60%, the ratio of the invisible part to the visible part is determined to be 4:6; when the superimposition range is 50%, the ratio of the invisible part to the visible part is determined to be 5:5; and when the superimposition range is 40%, the ratio of the invisible part to the visible part is determined to be 6:4.

[0077] In some other embodiments of the present application, the superimposition region can be divided into a left half and a right half according to the length of the superimposition region and the superimposition range, and the left half can be set as the visible part and the right half can be set as the invisible part, or the left half can be set as the invisible part and the right half can be set as the visible part. In actual applications, the above examples are not limited, and the following examples are described by dividing the superimposition region into an upper half and a lower half according to the width of the superimposition region and the superimposition range, in which the upper half is the invisible part and the lower half is the visible part. FIG. 9 is a schematic diagram of dividing the superimposition region based on the superimposition range according to an embodiment of the present application. For example, the superimposition range is 60%, and as shown in FIG. 9, the superimposition region is divided into two parts with a width of 4:6 according to the width, the upper half is the invisible part of the superimposition region, and the lower half is the visible part of the superimposition region.

[0078] In an embodiment of the present application, the transparency of the invisible part of the superimposition area is 0%. The visible part of the superimposition area can realize a gradual change of the transparency from 0 to 100%. For example, as shown in FIG. 9, the transparency of the initial position of the visible part of the superimposition area is 0%, and the transparency of the end position is 100%. The transparency corresponding to each width of the visible part can be determined according to a linear relationship between the width of the visible part and the range of the transparency interval. In an embodiment of the present application, the visible part can be divided into a plurality of sub-areas with equal width according to a preset number of areas, the serial numbers of the plurality of sub-areas are determined based on the number of areas, and the transparency corresponding to each serial number of the sub-areas is set; and different transparency intervals are set for each sub-area based on the transparency corresponding to each serial number of the sub-areas. The number of areas can be set according to actual needs, for example, set to 10. For example, the number of areas is 10, indicating that the visible part can be divided into 10 sub-areas. Based on the number of areas, the serial numbers of the 10 sub-areas can be determined in the order from top to bottom: the first sub-area, the second sub-area, the third sub-area, …, the tenth sub-area. Since the 10 sub-areas need to realize a gradual change of the transparency from 0 to 100%, the difference of the transparency of adjacent two sub-areas can be set to 10%, for example, the transparency interval of the first sub-area can be set to 0%-10%, the transparency interval of the second sub-area can be set to 11%-20%, the transparency interval of the third sub-area can be set to 21%-30%, …, and the transparency interval of the tenth sub-area can be set to 91%-100%.

[0079] In an embodiment of the present application, the superimposition range corresponding to the drag control bar can be displayed on the wallpaper preview interface, and when a user's drag operation on the drag control bar is received, the superimposition range can be adjusted. In another embodiment, the superimposition range can also be adjusted by a scalable rectangular frame. In an embodiment of the present application, the superimposition range corresponding to the drag control bar can be displayed on the wallpaper preview interface in response to a user's click on the target subject image. The drag control bar can be displayed on a preset position of the target subject image, such as the top, bottom, left, right, etc. In an embodiment of the present application, the superimposition range corresponding to the drag control bar can be displayed when a click operation on the wallpaper selection control is received, for example, can be displayed below the second option. FIG. 10 is a schematic diagram of a superimposition range drag control bar provided in an embodiment of the present application. For example, as shown in FIG. 10, the superimposition range corresponding to the drag control bar is displayed on the wallpaper preview interface, when a user's leftward drag operation on the drag control bar is received, the superimposition range is reduced; and when a user's rightward drag operation on the drag control bar is received, the superimposition range is increased.

[0080] In an embodiment of the present application, the superimposed region with completed transparency setting is superimposed on the target subject image to generate a target image, including: superimposing the superimposed region with completed transparency setting on the target subject image to obtain a first image; generating a second image according to a preset image size and the first image, the second image having the same size as the image size and including the first image; determining a background color corresponding to the second image, and coloring a region in the second image other than the first image based on the determined background color to obtain the target image. The position of the first image in the second image can be set according to the user's demand. In an embodiment of the present application, the first image is displayed in the center of the second image. In an embodiment of the present application, the background color corresponding to the second image can be determined based on the main color of the target subject image (or the first image). For example, the target main color corresponding to the main color of the target subject image (or the first image) can be determined based on a preset main color matching rule, and the determined target main color is used as the background color. In an embodiment of the present application, after at least one background color corresponding to the second image is determined, a background color option corresponding to the at least one background color can be displayed on the wallpaper preview interface, and the background color option is used to indicate the displayed background color. For example, as shown in (a) to (b) of FIG. 3, in response to the user's click on the wallpaper selection control, the background color option corresponding to the background color is displayed on the wallpaper preview interface. When the terminal device receives the user's selection operation on any background color option, the region in the second image other than the first image is colored based on the background color corresponding to the any background color option to obtain the target image. When the background color option is displayed on the wallpaper preview interface, more color options can also be displayed. The more color options are used to select the background color of the generated wallpaper. If the terminal device receives the user's click operation on the more color option, the target color is determined based on the user's operation, and the background color option is updated based on the determined target color, so that the updated background color option includes an option corresponding to the target color, and at this time, the option corresponding to the target color is in the selected state. After the target color is determined, the region in the second image other than the first image is colored based on the determined target color to obtain the target image.

[0081] In some embodiments of the present application, the generating the target image according to the target subject image and the superimposition region comprises: determining a third image; and generating the target image according to the target subject image, the superimposition region and the third image. The third image can be a picture of a pure color. The target subject image, the superimposition region and the third image are superimposed to generate the target image. In some embodiments, after the superimposition region is superimposed on the target subject image, the target subject image is superimposed on the third image, that is, in the order from top to bottom, the superimposition region is the first layer, the target subject image is the second layer, and the third image is the third layer. The positions of the target subject image and the superimposition region in the third image can be set according to the user's demand. In an embodiment of the present application, the target subject image and the superimposition region can be displayed in the center of the third image. The above-mentioned embodiments can enrich the content of the target image by superimposing the third image, so that the generated target image is more aesthetic.

[0082] In some embodiments, the determining the third image comprises: determining at least one background color based on a main color of the target subject image (or an image obtained by superimposing the target subject image and the superimposition region), and displaying a background color option corresponding to each of the at least one background color; and when the terminal device receives a selection operation on any background color option, generating the third image based on a background color corresponding to the any background color option. At least one target main color corresponding to the main color of the target subject image can be determined based on a preset main color matching rule, and the determined target main color is used as a background color to generate and display at least one background color option. In an embodiment of the present application, after the terminal device displays the at least one background color option, the terminal device can default to selecting a background color option corresponding to the highest recommendation degree of the main color of the target subject image among the displayed at least one background color option. The above-mentioned embodiments can generate a background color option corresponding to a background color based on the main color of the target subject image (or an image obtained by superimposing the target subject image and the superimposition region), so that the user can easily select a background color matching the target subject image (or an image obtained by superimposing the target subject image and the superimposition region) in color, and a more aesthetic wallpaper can be generated more easily.

[0083] In an embodiment of the present application, when the background color option is displayed on the wallpaper preview interface, more color options can also be displayed. The more color options are used to select the background color of the third picture. If a user's click operation on the more color options is received, the target color is determined based on the user's operation, and the background color options are updated based on the determined target color, so that the updated background color options include the option corresponding to the target color, and the option corresponding to the target color in the updated background color options is in a selected state. After the target color is determined, the third image is generated based on the determined target color, and the color of the third image is the target color. The above method can provide more background color options for the user, increase the user's interaction in the wallpaper generation process, and improve the user experience. At the same time, the generated wallpaper can better meet the user's needs.

[0084] In some embodiments of the present application, if the wallpaper is a lock screen wallpaper, generating a target image according to the target subject image and the superimposition region includes: determining a third image; generating a clock layer; and generating the target image according to the target subject image, the superimposition region, the third image, and the clock layer. The clock layer, also known as the lock screen clock, is used to display the current time and can be generated through the lock screen interface function in the operating system of the terminal device. The time format and style of the clock layer can be set according to the user's needs. FIG. 11 is a schematic diagram of an image superimposition sequence provided in an embodiment of the present application. As shown in FIG. 11, in the order from top to bottom, the superimposition region is the first layer, the target subject image is the second layer, the clock layer is the third layer, and the third image is the fourth layer, which are superimposed in this order to obtain the target image. In an embodiment of the present application, the text area of the clock layer partially overlaps the target subject image, so that the target subject image covers part of the content in the text area of the clock layer, showing a sense of hierarchy and creating a depth of field effect. In an embodiment of the present application, the color of the text in the clock layer can be determined based on the dominant color of the target subject image or the dominant color of the image obtained by superimposing the target subject image and the superimposition region. For example, the color of the text in the clock layer can be determined based on a preset dominant color matching rule and the dominant color of the target subject image (or the image obtained by superimposing the target subject image and the superimposition region), so that the color of the text in the clock layer matches the dominant color of the target subject image (or the dominant color of the image obtained by superimposing the target subject image and the superimposition region). The above method can generate a lock screen wallpaper with a superimposition effect because the clock layer is in the third layer and is superimposed by the superimposition region and the target subject image.

[0085] In an embodiment of the present application, after the target image is generated according to the target subject image, the superimposed region and the third image, the method further comprises: determining a first region corresponding to the target image based on a preset adjustment rule; when the terminal device receives a first operation on the first region, adjusting the target subject image to obtain an adjusted target subject image; adjusting the superimposed region according to the adjusted target subject image to obtain an adjusted superimposed region; and updating the target image based on the adjusted target subject image and the adjusted superimposed region.

[0086] The adjustment rule can be set according to user demand. For example, the adjustment rule can comprise determining a bisector of the target subject image in the width direction, and determining the region above the bisector as the first region based on the width of the target subject image. FIG. 12 is a schematic diagram of determining a first region according to an embodiment of the present application. As shown in FIG. 12, a bisector of the target subject image in the width direction is determined, and the region above the bisector is determined as the first region. The first region is the region of the target image in which the target subject image is adjusted. The user can perform a corresponding action in the first region to achieve an adjustment operation (i.e., a first operation) on the target subject image. For example, the first operation can comprise one or a combination of multiple operations such as a zoom-in operation, a zoom-out operation, a moving operation, etc. The zoom-in operation is used to zoom in the target subject image, the zoom-out operation is used to zoom out the target subject image, and the moving operation is used to move the target subject image. A gesture action corresponding to each first operation can be preset. For example, a pinch operation of two hands corresponds to a zoom-out operation, a double-finger moving operation corresponds to a zoom-in operation, and a long-pressing and dragging operation corresponds to a moving operation. According to the above embodiment, the display of the target subject image on the target image can be adjusted based on the first operation of the user in the first region.

[0087] In an embodiment of the present application, adjusting the superimposed region according to the adjusted target subject image comprises: when the target subject image is zoomed in, zooming in the superimposed region to obtain a zoomed-in superimposed region; when the target subject image is zoomed out, zooming out the superimposed region to obtain a zoomed-out superimposed region; and when the target subject image is moved, moving the superimposed region to obtain a moved superimposed region. When the size of the target subject image changes, the size of the superimposed region changes by a corresponding proportion, so that the sizes of the target subject image and the superimposed region are consistent. When the position of the target subject image changes, the position of the superimposed region changes, so that the positions of the target subject image and the superimposed region are consistent.

[0088] In an embodiment of the present application, after the target image is generated according to the target subject image, the superimposed region and the third image, the method further comprises: determining a second region corresponding to the target image based on the adjustment rule; when the terminal device receives a second operation on the second region, adjusting the superimposed region to obtain an adjusted superimposed region, the display content of the adjusted superimposed region being different from the display content of the superimposed region, the size of the adjusted superimposed region being the same as the size of the superimposed region; and updating the target image based on the target subject image, the adjusted superimposed region and the third image. The above embodiment can adjust the display content of the superimposed region based on the second operation of the user on the second region.

[0089] The adjustment rule can be set according to user needs. For example, the adjustment rule can comprise determining a bisector of the target subject image in the width direction based on the width of the target subject image, and determining a region below the bisector as the second region. For example, as shown in FIG. 12, a bisector of the target subject image in the width direction is determined, and a region below the bisector is determined as the second region. The second region is a region of the target image in which the superimposed region is adjusted. The user can perform a corresponding action in the second region to implement an adjustment operation (i.e., a second operation) on the superimposed region. For example, the second operation can comprise one or a combination of multiple operations such as a zoom-in operation, a zoom-out operation and a moving operation. The zoom-in operation is used to zoom in the superimposed region, the zoom-out operation is used to zoom out the superimposed region, and the moving operation is used to move the superimposed region.

[0090] Since the superimposition region is limited in size and position of the target subject image, after the adjustment operation on the superimposition region, the adjusted superimposition region is determined based on the target subject image again, and the target image is updated based on the target subject image, the adjusted superimposition region and the third image. The adjusted superimposition region is still in the contour corresponding to the target subject image and does not exceed the contour corresponding to the target subject image.
