     DESCRIPTION OF EMBODIMENTS 
     The following clearly describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. 
     The terms “first”, “second”, and the like in the specification and claims of the present application are used to distinguish between similar objects instead of describing a specific order or sequence. It should be understood that the data used in such a way is interchangeable in proper circumstances so that the embodiments of the present application can be implemented in an order other than the order illustrated or described herein. In addition, objects distinguished by “first”, “second”, and the like usually belong to one type, and the number of the objects is not limited. For example, there may be one or more first objects. In addition, in the specification and the claims, “and/or” represents at least one of connected objects, and a character “/” generally represents an “or” relationship between associated objects. 
     The image display method provided in the embodiments of the present application are described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings. 
     As shown in  FIG.  1   , an embodiment of the present application provides an image display method, applied to an electronic device and including: 
     Step  101 : Receive a first input performed by a user, where the first input is used to trigger lighting of the screen of an electronic device. 
     The first input is an input performed when the electronic device is in a screen-off state. Alternatively, the user can perform the first input in an unlocking scenario of the electronic device, or perform the first input in the scenario where screen-locking information of the electronic device is to be viewed. The first input may be a tap input, a double-tap input, or the like. 
     Step  102 : In response to the first input, control an object layer image of a wallpaper image of the screen of the electronic device to execute a first display animation based on a first animation parameter, and control a background layer image of the wallpaper image to execute a second display animation based on a second animation parameter. 
     The first animation parameter and the second animation parameter are different. 
     In this step, after receiving the first input, the object layer image and the background layer image are dynamically displayed on the screen according to different animation parameters. For example, the object layer image is displayed in a manner of diffuse lighting, and the background layer image is displayed in a manner of slowly lighting. The first display animation refers to an animation when the object layer image is displayed according to the first animation parameter, and the second display animation refers to an animation when the background layer image is displayed according to the second animation parameter. 
     In this way, the object layer image and the background layer image are displayed based on different animation parameters, which can effectively distinguish the object layer image from the background layer image in the wallpaper image, and then can highlight the object layer image in the wallpaper image. In addition, any image set as the wallpaper by the user can achieve the effect of highlighting the object layer image in the wallpaper image, thereby strengthening the function of the wallpaper in the process of using the mobile terminal by the user. 
     Optionally, before the controlling an object layer image of a wallpaper image of the screen of the electronic device to execute a first display animation based on a first animation parameter, and controlling a background layer image of the wallpaper image to execute a second display animation based on a second animation parameter; the method further includes: 
     separating an object layer from a background layer of the wallpaper image to obtain the object layer image and the background layer image, and in a process of separating the object layer from the background layer of the wallpaper image, recording outline information and center point information of the object layer image. 
     The object layer may refer to a screen subject in the wallpaper image, and the screen subject may be a person or an object, a single person (object), or multiple persons (objects). The background layer may refer to an image other than the object layer in the wallpaper image. If there are multiple persons or objects, the wallpaper image includes multiple object layer images. Optionally, each person or object may correspond to one object layer image, or two or more persons or objects may correspond to one object layer image. For example, if the screen subject includes person A and person B, the object layer image includes two object layer images formed by person A and person B respectively. 
     In this step, the object layer and the background layer of the wallpaper image can be separated through an image recognition technology. Optionally, after separation, each person or object can correspond to one object layer image, or two or more persons or objects can correspond to one object layer image. As shown in  FIG.  2   , an object layer image  201  and a background layer image  202  are obtained, and in the process of separating the object layer from the background layer of the wallpaper image, outline information and center point information of the object layer image are recorded. 
     Herein, by separating the object layer from the background layer of the wallpaper image, it is convenient to subsequently display the object layer image and the background layer image based on different animation parameters, so as to achieve the purpose of highlighting the object layer image, thereby strengthening the function of the wallpaper in the process of using the mobile terminal by the user. 
     Optionally, the controlling an object layer image of a wallpaper image of the screen of the electronic device to execute a first display animation based on a first animation parameter includes: 
     according to the outline information and the center point information of the object layer image, controlling the object layer image of the wallpaper image of the screen of the electronic device to execute the first display animation in a preset manner; 
     where the preset manner includes at least one of the following: 
     a manner of spreading from the center point to the surrounding, and a manner of gathering from the surrounding to the center point. 
     Of course, the preset manner may also include other animation display manners in the prior art, which are not specifically limited herein. 
     According to the above description, in the embodiments of the present application, in the process of separating the object layer image from the background layer image, the outline information and the center point information of the object layer image are recorded. In a specific implementation, as shown in  FIG.  3     a,  a mask is generated based on an outline according to the outline information of the object layer image, and a display area of the object layer image is controlled by the mask, so that the display area of the object layer image is gradually enlarged during the animation process, so as to achieve the visual effect that the object layer image diffuses and brightens in combination with its own shape. Alternatively, as shown in  FIG.  3     b,  the display area of the object layer image is directly controlled to gradually spread during the animation process. 
     Here, according to the outline information and the center point information of the object layer image, the object layer image of the wallpaper image of the screen of the electronic device is controlled to execute the first display animation in a preset manner, which can realize that the object layer image executes the visual effect of the first display animation in combination with its own shape. 
     Optionally, the first animation parameter changes from a first numerical value to a second numerical value within a first animation duration, and the second animation parameter changes from a third numerical value to a fourth numerical value within a second animation duration; 
     The first animation duration is less than the second animation duration, and the first numerical value is greater than or equal to the third numerical value. 
     The first animation parameter includes at least one of transparency and brightness. 
     The second animation parameter includes at least one of transparency and brightness. 
     The first animation duration is an animation duration corresponding to the object layer image, and the second animation duration is an animation duration corresponding to the background layer image. 
     It should be noted that, in this embodiment of the present application, the first animation duration is a duration corresponding to a first time period, a time range of the first time period is from a first time to a second time, and the second animation duration is a duration corresponding to a second time period, a time range of the second time period is from a third time to a fourth time, where the first time and the third time may be the same or different, that is, the start time of the first animation duration and the start time of the second animation duration can be the same or different. 
     In addition, when the object layer image includes multiple objects, the multiple objects may be displayed simultaneously in an animated manner within the first animation duration according to the first animation parameter, or may be sequentially displayed in an animated manner within the first animation duration according to the first animation parameter. 
     For the object layer image, the first animation duration is T 1 , the variable value of transparency is A 1 , and the variable value of brightness is L 1 . For the background layer image, the second animation duration is T 2 , the variable value of transparency is A 2 , and the variable value of brightness is L 2 . T 2  should be greater than T 1 , and the numerical changes of A 1 , L 1 , A 2 , and L 2  should be controlled by different animation interpolators. It is assumed that the transparency of the object layer image changes from 50% (the first numerical value above) to 100% (the second numerical value above), the brightness changes from 20% (the first numerical value above) to 100% (the second numerical value above), and the animation duration is 500 ms (the first animation duration), the transparency of the background layer image changes from 0% (the third numerical value above) to 100% (the fourth numerical value above), and the brightness changes from 0% (the third numerical value above) to 100% (the fourth numerical value above), and the animation duration is 800 ms (the second animation duration). Assuming that the start times corresponding to the first animation duration and the second animation duration are the same (both are 0 ms), at 100 ms, the brightness of the object layer image is 50%, the transparency of the object layer image is 50%, the brightness of the background layer is 20%, and the transparency of the background layer is 20%; at 300 ms, the brightness of the object layer image is 70%, the transparency of the object layer image is 70%, the brightness of the background layer is 40%, and the transparency of the background layer is 40%; at 500 ms, the brightness of the object layer image is 100%, the transparency of the object layer image is 100%, the brightness of the background layer is 70%, and the transparency of the background layer is 70%. 
     In this way, through the first animation parameter and the second animation parameter, the object layer image in the wallpaper image diffuses and brightens, and the background layer image slowly brightens, thereby achieving the effect of highlighting the object layer image. 
     It should be noted that, in this embodiment of the present application, in addition to displaying different display effects to the user through brightness and transparency, the object layer image can also be highlighted through animation scaling of different amplitudes, or the object layer image can be highlighted through displacement animation of different amplitudes. 
     Optionally, the wallpaper display control method of the embodiments of the present application further includes: 
     receiving a second input performed by the user on the screen; 
     determining an input parameter of the second input, where the input parameter includes at least one of an input time and an input location; and 
     executing a target control function according to target information; 
     where the target information includes at least one of the following: a first relationship, a second relationship, and a real-time display area of the wallpaper image; 
     where the first relationship refers to a relationship between the input time and the first animation duration and the second animation duration, the second relationship refers to a relationship between the input position and a first display area and a second display area, the first display area is a display area corresponding to the object layer image, and the second display area is a display area corresponding to the background layer image; 
     The real-time display area of the wallpaper image is a real-time display area of the background layer image or a real-time display area of the object layer image. 
     The second input may be a tap input, a double-tap input, or the like. 
     Herein, different target control functions are triggered according to at least one of the input time of the second input, the input position of the second input, and the real-time display area of the wallpaper image, thereby realizing the interaction between the user and the wallpaper image. Besides, the interaction between the user and the wallpaper image triggers different target control functions, which can effectively protect the privacy and security of a machine owner mode. 
     Optionally, the performing the target control function according to the target information includes: 
     when the input time is within a time range corresponding to the first animation duration, and the input position is within the first display area, displaying an unlock interface; 
     or when the input time is within the time range corresponding to the first animation duration, the input position is within the first display area, and the input track of the second input is a preset track, displaying the target information of a preset application program. 
     Assuming that the first animation duration is the duration corresponding to the first time period, the first time period is from 0 ms to 10 ms, and the second input is input at the second ms, the input time of the second input is within a time period corresponding to the first animation duration. If the input position is still in the first display area, the unlock interface is displayed, the unlock interface includes a password input keyboard, and the user can enter the machine owner mode only after entering a correct password. On the contrary, unlock to enter through other methods is in a guest mode. Therefore, even if the password is leaked and there is no correct interaction with the display effect of the wallpaper image, it is difficult to enter the machine owner mode, thereby effectively protecting the privacy and security of the machine owner mode. 
     Exemplarily, the second input is a slide-down input and slides down in the first display area within the first display duration, and the input track of the second input is a preset track. In this case, the weather information of the weather application program is displayed, so that the user can easily check local weather. 
     Herein, a specific function is triggered by a specific gesture, so that the user can interact with the display effect of the wallpaper image, and the wallpaper image is further empowered on the basis of appreciation. In addition, different target control functions are triggered by interaction between the user and the wallpaper image, and the target control functions can effectively protect the privacy and security of the machine owner mode. 
     Optionally, the performing the target control function according to the target information includes: 
     when the input time is outside the time range corresponding to the first animation duration, the input time is within the time range corresponding to the second animation duration, and the input position is located in the second display area, displaying a program interface of a preset application program. 
     It is assumed that the first animation duration is the duration corresponding to the first time period, the first time period is from 0 ms to 10 ms, and the second animation duration is the duration corresponding to the second time period, the second time period is from 1 ms to 15 ms, and the second input is input at the 11th ms. In this case, the input time of the second input is outside the time period corresponding to the first animation duration and within the time period corresponding to the second animation duration. If the input position is still in the second display area, the program interface of the preset application program is displayed, for example, a contact interface of an instant chat application is entered. 
     Herein, through the interaction between the user and the display effect of the wallpaper image, the purpose of quickly displaying the application information that the user wishes to see is achieved, and at the same time, the privacy and security of the machine owner mode can be effectively protected. 
     Optionally, the performing the target control function according to the target information includes: 
     triggering to execute a first object control function when the display area of the object layer image is larger than a first preset threshold and the input position is located in the first display area; and 
     triggering to execute a second object control function when the display area of the object layer image is larger than a first preset threshold and the input position is located in the second display area; 
     where the first target control function and the second target control function are different control functions. 
     It should be noted that the difference between the first target control function and the second target control function may be that the two control functions correspond to different modes, or the two control functions themselves are different. 
     For example, the first target control function is to control the terminal display interface to be displayed in a first mode (daytime mode), and the second target control function is to control the terminal display interface to be displayed in a second mode (night mode). For another example, the first target control function is to display a contact interface of an instant chat application, and the second target control function is to display a shopping page of a shopping application. 
     Herein, combined with the display effect of the wallpaper image, a specific function is triggered by a specific gesture. For example, clicking the first display area and the second display area respectively can trigger different functions, so that the user can interact with the display effect of the target image, which further empowers the wallpaper image on the basis of appreciation, and at the same time, can effectively protect the privacy and security of the machine owner mode. 
     In the wallpaper display control method of the embodiments of the present application, the user can see the visual effect that the object layer image of the wallpaper image brightens first and then the background layer image brightens when the screen is lit, and the effect of the gradual diffusion combined with the shape outline displayed in a process of brightening the object layer image can bring a good visual experience to the user. This method can not only effectively highlight the user&#39;s wallpaper among the many information on the screen, but also enable different wallpapers set by the user to apply this effect. In addition, users can also activate specific functions through specific gestures in combination with display effects. 
     It should be noted that, in the wallpaper display control method provided by the embodiments of the present application, the execution body may be a wallpaper display control apparatus, or a control module in the wallpaper display control apparatus for executing the wallpaper display control method.
