  • Method and apparatus for increasing effective contrast ratio and brightness yields for digital light valve image projectors
    Patent number: 9300900
    Abstract: A method and apparatus for increasing the effective contrast ratio and brightness yields for digital light valve image projectors using a variable luminance control mechanism (VLCM), associated with the projector optics, for modifying the light output and provide a correction thereto; and an adaptive luminance control module (ALCM) for receiving signals from the video input board, the adaptive luminance control module producing a signal on a VLCM bus connecting the variable luminance control mechanism and the adaptive luminance control module, the signal causing the variable luminance control mechanism to change the luminance of the light output and provide a corrected video signal for the projector.
