Abstract
An apparatus and a system for viewing a 3D image including a synchronization signal receiver for receiving 3D image synchronization signal; a 3D control signal generator for generating left-eye glass control signal and a right-eye glass control signal in accordance with the synchronization signal received; a left-eye glass that opens or intercepts light transmitted to the left-eye glass; a right-eye glass that opens or intercepts light transmitted to the right-eye glass; a central processor that controls operation of the 3D control signal generator and transmits the synchronization signal to the 3D control signal generator; and a power controller that connects or intercepts power supplied to the synchronization signal receiver and the central processor. The power consumption of the apparatus is minimized by supplying power to the synchronization signal receiver and the central processor at a time when the synchronization signal is received and power is intercepted during the rest period.
