Abstract
A 3D video viewing shutter device receives display response time from a 3D video display device for determining shutter open and close times. Response time may correspond to display type, a particular display and/or a change in pixel illumination levels between frames. The shutter device receives response information during device initialization and/or corresponding to changing pixel illumination levels. A sequence of 3D frames may comprise a pattern of left frames, right frames, blank frames and/or frames comprising a combination of left and right frames. Based on display device and/or shutter device response times, the shutter device may extend shutter transmittance time during a frame display interval into a blank frame interval. Transmittance may be enabled during display of blank frames subsequent to left or right frames. The shutter device and display device may communicate via a wireless link for example, via a Bluetooth wireless link utilizing Bluetooth clocks.
