<P>PROBLEM TO BE SOLVED: To provide eyeglasses for a stereoscopic image which can reduce current consumption and improve noise resistance even when frame frequency becomes high. <P>SOLUTION: After detecting the period of a synchronization signal by a period detection unit 15 and storing liquid crystal shutter control data in a liquid crystal shutter control data storage unit 18, reception stop time control means suspends reception by a wireless signal reception unit 11, generates the opening and closing of a liquid crystal shutter by a liquid crystal shutter control timing generation unit 20 on the basis of a period signal generated by a period signal generation unit 16 and the liquid crystal shutter control data stored in the liquid crystal shutter control data storage unit 18, and opens and closes the liquid crystal shutter 22b by a liquid crystal shutter control unit 21 on the basis of the timing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
