Abstract
Abstract This invention provides a multi-screen display system, which unifies the control relating to each image on a multi-screen. The multi-screen display system receives images from a plurality of image sources, and displays the received images at the same time on the multi-screen of a display device. In the multi-screen display system, a multi-screen control part determines a type of each image source and a display region where a multi-screen control cursor is positioned on the multi-screen. The multi-screen control part determines a role of the multi-screen control cursor in the display region according to the type of the image source of an image displayed in the display region where the multi-screen control cursor is positioned. The multi-screen control part controls generation of the multi-screen control cursor and the operation thereof so that the multi-screen control cursor can play the determined role.
