Abstract
A video controller for synchronizing presentation of a plurality of images is provided. A color switching device is operable to continually select a color out of a set consisting essentially of a plurality of fundamental colors. Each fundamental color is selected for presentation for a fixed time segment. A light processing element is operable to block and permit transmission of light in each color selected by the color switching device during each fixed time segment. The light includes at least two streams of sequential images. A synch signal generator is in control of the light processing element and is configured to time presentation of the light by the light processing element and of control signals to a viewing device of the display. The presentation of the light and of the control signals is timed in synchrony with the fixed time segments only during a transition state of the viewing device.
