Abstract:
A system for cycling a right-eye shutter between a substantially transparent state and a substantially opaque state in substantial synchronism with a right-eye sequence of images shown on a display and for cycling a left-eye shutter between a substantially opaque state and a substantially transparent state in substantial synchronism with a left-eye sequence of images shown on the display, comprising:cycling means for cycling the right-eye shutter between the substantially transparent state and the substantially opaque state at a predetermined frequency and for cycling the left-eye shutter between the substantially transparent state and the substantially opaque state at the predetermined frequency; and synchronization means for synchronizing the cycling means with the image sequences shown on the display by detecting at least one synchronization image displayed on the display; wherein the cycling means cycles each of the right-eye shutter and the left-eye shutter at the predetermined frequency even after the synchronization image is no longer detected by the synchronization means.
