Abstract
An image system comprises an image display device which displays images, and image viewing eyeglasses used for viewing images displayed by the image display device. The image display device comprises an image display device configured to display image; and image viewing eyeglasses used for viewing the image displayed by the image display device, wherein the image display device includes: a display portion configured to display the image in time series to be viewed using the image viewing eyeglasses; a synchronization signal generator configured to generate a synchronization signal in synchronization with frame of the image, the synchronization signal including prescribed bit series to transmit bit data described by the presence or absence of a pulse; and a synchronization signal transmitter configured to transmit the synchronization signal, and the image viewing eyeglasses include: an optical filter portion configured to adjust an amount of light transmitted to a left eye and a right eye of a viewer; a synchronization signal receiver configured to receive the synchronization signal transmitted from the synchronization signal transmitter; a synchronization signal analyzer configured to detect the bit series, analyze a pattern of the bit series during a predetermined detection time when the synchronization signal analyzer detects the first pulse received by the synchronization signal receiver, and generate control data to control the optical filter portion; and an optical filter controller configured to control the optical filter portion with the control data.
