MULTI-DISPLAY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To make it unnecessary for an operator to move a display screen by moving an operation screen to the front of the operator when an application for performing display operation is changed.

SOLUTION: When an image detection condition is satisfied, which position of a virtual page 5 is the position of a mouse is detected. Then the existence of the mouse on a 2nd sub-display device 8 is judged from the position detection result. When a judged operation picture is not a main display device 6, the picture contents of the 2nd sub-display device 8 and that of the main display device 6 are exchanged with each other and the exchanged contents are displayed on respective display devices 6, 8. Namely the picture contents of the 2nd sub-display device 8 are transferred to the main display device 6 and the picture contents of the main display device 6 are transferred to the 2nd sub-display device 8. Thus an operation area shown by the mouse can be arranged always on the front and the operation efficiency of picture display can be furthermore improved.
