SYNCHRONIZATION CIRCUITS AND METHODS USABLE IN SHUTTER GLASSES |
摘要 |
Described herein are circuits and methods enabling a user to view 3D video using shutter glasses. The shutter glasses can wirelessly receive a video synchronization signal to synchronize the timing of a shutter operation with the timing of displayed video. A self-timing signal can be generated based on a measured period of the video synchronization signal. A low-power mode of operation can be entered for a period of time in which reception of the video synchronization signal is disabled and the shutter operation is controlled based on the self-timing signal.
