Abstract
A transmission device displays a public image (a first image) provided to unspecified users, a private image (a second image) provided to particular users, and a mask image of the private image in a time division multiplexed manner, and transmits a private image sync signal synchronized with display of the private image. A reception device receives the private image sync signal transmitted from the transmission device and shoots by a shooting unit the private image displayed on the transmission device by using the private image sync signal, and displays the shot image on a display unit.
