MULTI-DISPLAY CONTROL SYSTEM AND IMAGE DISPLAY APPARATUS

A multi-display control system enables an operation screen to come up on an operator's front screen when an application performing a display operation changes, without the need for the operator to move the display image.When the conditions for image detection have been met, it is detected where the position of a mouse is on a hypothetical single-sheet page 5 (process 1). Next, from the position detection result it is assessed if the mouse is on a second sub display apparatus 8 (process 2). Then in the case where the assessed operating screen is not the main display apparatus 6, the screen contents of the second sub display apparatus 8 and the screen contents of the main display apparatus 6 are exchanged and displayed on the respective image display apparatuses. That is, the screen contents of the second sub display apparatus 8 are transformed to the main display apparatus 6, and the screen contents of the main display apparatus 6 are transformed to the second sub display apparatus 8 (process 3). As a result, the working space shown by the mouse can always be brought to the front screen, and the operating efficiency of the image display can be further improved.
