Abstract

A display system displays a received image on a display device based on image information transmitted from at least one image supply device via a network. An image generating unit generates a segmented image segmented into plural individual areas, the segmented image contains an individual connection image representing connection information for the image supply device to connect to the display device in an area correlated to one individual area of the plural individual areas. A determining unit determines whether connection is permitted or not based on the connection request information. When connection to the image supply device is permitted by the determining unit, the image generating unit generates the segmented image containing the received image based on the image information from the image supply device in the individual area.
