<P>PROBLEM TO BE SOLVED: To reduce costs incurred to users. <P>SOLUTION: An image display device 10 comprises: an image display part 110 which displays 3D images; a synchronization signal transmission part 121 which transmits a synchronization signal which synchronizes a display timing of the 3D images and 3D glasses 20 to the 3D glasses 20; and a protocol transmission part 123 which transmits protocol information used for analysis of the synchronization signal to the 3D glasses 20. The 3D glasses 20 comprises: a shutter part 240; a protocol storage part 290 which stores the protocol information; a synchronization signal reception part 221 which receives the synchronization signal; a shutter drive part 230 which analyzes the synchronization signal using the protocol information stored in the protocol storage part 290 to drive the shutter part based on the analysis result; a protocol reception part 223 which receives the protocol information; and a protocol update part 280 which updates the protocol information stored in the protocol storage part 290 to the received protocol information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
