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.

Video controller for synchronizing presentation of a plurality of images projected onto a display

A system and method for improving stereoscopic images produced by a projecting device containing a single chip DMD, seen through an eye-switching device, such as a pair of liquid crystal (LC) shutter glasses. The system and method are used with a video projector designed to be used with a multiple-color, color switching device, such as a color wheel. The color wheel includes at least three critical color segments. The color wheel may also physically include or be electronically re-defined to include at least one non-critical segment. A color sequencing firmware resident in the video projector is used to align a non-critical segment in front of the projector's main light source during the eye-switching device's unstable transition phase. If the non-critical segment is transmissive, the firmware controls the DMD so that light is discontinued. If the non-critical segment is non-transmissive, the light is physically blocked. If the non-critical segment is electronically defined, the firmware directly controls the DMD to discontinue the transmission of light for at least the duration of the eye-switching device's unstable transition phase.
