ABSTRACT:
A method and system for accentuating intense white display areas in sequential DMD video systems includes generating a special signal for each pixel that indicates whether to boost the intensity of that pixel in all colors. The method further includes enabling the mirrors to be turned on during times of color boundary of the color wheel such that DMD with mirrors receives different mixes of color light that are integrated together to produce intense white. The system may include degamma lookup tables for each color. The degamma lookup tables are augmented when the special signal is generated.
