An image receiving unit receives a first image signal transmitted from a first image transmitting unit and a second image signal transmitted from a second image transmitting unit, synthesizes the first and second image signals, and displays them on the same display screen. The image receiving unit transmits information about display areas of the first and second image signals, i.e., image plane setting information, to each image transmitting unit. In accordance with the image plane setting information, each image transmitting unit reduces the data amount of a display area the first and second image signals are displayed in an overlap manner, prior to transmitting the first and second image signals. Also in accordance with the image plane setting information, each image transmitting unit processes the first or second image signals so as to match a display area thereof, prior to transmitting the first and second image signals.
