The selecting of at least one image in the first display screen as the target image is, for example, selecting the target image by mouse clicking the image or mouse frame selection, but the invention is not limited thereto.
The second display screen mentioned in step S13 is, for example, an LED display screen, and the display range of the second display screen is generally larger than that of the first display screen. The display expansion screen of which the second display screen is referred to as the first display screen is represented as follows: the display contents of the first display screen and the second display screen are integrated, namely the display contents can be displayed by moving back and forth between the first display screen and the second display screen. The mapping relation between the mapping window and the second display screen is mentioned, namely the display content of the second display screen is displayed in the mapping window in real time.
Step S13 includes, for example: and moving the target image, judging whether the target image exceeds the display range of the first display screen, and displaying the mapping window in the first display screen when the target image is judged to exceed the display range of the first display screen. The mapping window is displayed in the first display screen under a trigger condition, and when the target image is detected to be moved, dragged and the like, and the target image exceeds the display range of the first display screen, the mapping window can be displayed in the first display screen, or the mapping window can be displayed in the first display screen after the target image is directly detected to exceed the display range of the first display screen. Of course, the present invention is not limited thereto, the display of the mapping window may also be set according to the actual situation of the user, or no trigger condition is set, and when the first display screen and the second display screen establish the screen expansion display connection, the mapping window will be displayed in the first display screen.
Further, step S13, for example, further includes: determining the window size of the mapping window according to the first display screen size of the first display screen; and displaying the mapping window at a preset position of the first display screen based on the window size. Specifically, the size of the mapping window depends on the size of the display screen of the first display screen, so that the mapping window can be ensured to be displayed in the first display screen without exceeding the display range of the first display screen.
