Abstract
A method for increasing the brightness of a scene in a color projection system is disclosed. The brightness can be increased in both temporal and spatial filtering systems. In a temporal system, a portion of the total illumination time is allocated to white light to raise the overall brightness. In a spatial system, part of the illuminated area is allocated to white light. The parts could be allocated as regions on a spatial light modulator, or a spatial light modulator could be dedicated to that area to use white light.
