A controller(20) manages the drive and control of a left/right eye liquid crystal by a synchronizing signal transmitted from an image output device. An image output device outputs the left/right screen of A image and the left/right screen of B screen successively and transmits the synchronizing signal of the left/right screen of A screen and the synchronizing signal of the left/right screen of B screen respectively at the same time. A pair of liquid crystal shutter glasses is operated by selecting a synchronizing signal about the left/right screen of a screen or a synchronizing signal about the left/right screen of B screen.
