In this example, the electronic device takes a mobile phone as an example. As shown in Figure 1, the display screen of the mobile phone displays a home screen interface 101. The home screen interface includes application icons for each application, such as clock application icons, calendar application icons, etc. As shown in 1a of Figure 1 , the user can click the icon of the clock application, and the mobile phone starts the clock application in response to the user's click operation, as shown in 1b of Figure 1 , in which the clock interface 102 is displayed on the display screen. The user can click the return button on the mobile phone to return to the home screen interface 101. The user can click the icon of the calendar application in the home screen interface 101, and the mobile phone starts the calendar application in response to the user's operation of clicking the icon of the calendar application. As shown in 1c in Figure 1, the display screen displays the calendar interface 103. The user can enter multi-tasking operations, as shown in 1c of Figure 1. The user can slide up in the direction of the black arrow, and the phone enters the multi-tasking interface in response to the user's sliding up operation. As shown in 1d of Figure 1, the multitasking interface 104 is displayed on the display screen of the mobile phone. The multitasking interface includes interface thumbnails of applications running in the background of the mobile phone. As shown in 1d, the mobile phone enters the multitasking interface before entering the multitasking interface. The calendar application, clock application and settings application have been run. These three applications run in the background when the phone returns to the home screen interface. When the mobile phone enters multitasking, the multitasking interface 104 will display the interface thumbnails of the three background running applications in the multitasking interface with animated special effects. For example, when entering the multitasking interface, the thumbnails of the clock interface, The thumbnails of the settings interface and the thumbnails of the calendar interface are displayed on the display screen in sequence.
多任务界面的背景图像通常是根据当前手机的壁纸确定。示例性地，手机在检测到多任务的操作时，检测当前手机的壁纸是否为静态壁纸，若手机确定为静态壁纸类型，则从手机的壁纸资源中获取静态壁纸，并对静态壁纸进行模糊处理，获得模糊处理后的静态壁纸作为该多任务界面的背景图像。若手机确定壁纸为非静态壁纸类型(如超级壁纸类型或动态壁纸的类型)，则手机对当前采用的壁纸进行截屏操作，对截屏图像进行模糊处理，将模糊处理后的截屏图像作为多任务界面的背景图像。由于每次在检测到多任务操作时，该手机都需要进行上述操作，而模糊处理进一步增加了手机的运算量，会导致在该多任务界面的背景图像上以动画形式展示后台应用的界面缩略图时，出现丢帧、卡顿的问题，导致后台应用的界面缩略图的显示不流畅，给用户留下手机卡的使用体验。The background image of the multitasking interface is usually determined based on the current wallpaper of the mobile phone. For example, when the mobile phone detects a multi-tasking operation, it detects whether the current mobile phone's wallpaper is a static wallpaper. If the mobile phone determines that it is a static wallpaper type, it obtains the static wallpaper from the mobile phone's wallpaper resource and blurs the static wallpaper. , obtain the blurred static wallpaper as the background image of the multi-tasking interface. If the mobile phone determines that the wallpaper is a non-static wallpaper type (such as a super wallpaper type or a dynamic wallpaper type), the mobile phone takes a screenshot of the currently adopted wallpaper, blurs the screenshot image, and uses the blurred screenshot image as the multi-tasking interface background image. Since the phone needs to perform the above operations every time a multitasking operation is detected, the blur processing further increases the calculation load of the phone, causing the interface shrinkage of the background application to be displayed in an animated form on the background image of the multitasking interface. When thumbnails are taken, problems such as frame loss and freezing occur, causing the thumbnails of the background application interface to be displayed unsmoothly, leaving users with a stuck experience.
