<P>PROBLEM TO BE SOLVED: To solve the problem in which: in an environment having a plurality of video systems, a synchronization signal transmitted from a display to an eyeglass device is likely to interfere with other video systems. <P>SOLUTION: A filter constraining properties of light of a transmitted synchronization signal is disposed at the front of a synchronization signal transmission unit of a display. Also, a reception filter constraining properties of the light of the received synchronization signal is disposed at the front of a synchronization signal reception unit of an eyeglass device. When coordinating the properties of the filter with that of the reception filter, it is possible to transmit/receive the synchronization signal between them by the light with the coincident properties so that interference can be suppressed in comparison with the conventional manner. <P>COPYRIGHT: (C)2013,JPO&INPIT |
