Image display apparatus and shutter device

摘要

An image display apparatus includes an image display unit that displays an image for a stereoscopic image, a light-source control unit that controls a light source of the image display unit, a content discriminating unit that discriminates whether the image displayed on the image display unit is a limited image requiring viewing limitation or an unlimited image not requiring the viewing limitation, and a shutter control unit that controls shutter of shutter devices. The light-source control unit controls the light source to reduce light emission in a second period compared with light emission in a first period. The shutter control unit controls, during the display of the limited image, the shutter device set in a viewing limitation mode for limiting viewing of the limited image, to close the shutter in the first period and open the shutter in the second period.
