  • Light source response compensation for light projection system using a graphics processing unit
    Patent number: 10469813
    Abstract: A light projection system includes a light module emitting a light beam and a movable mirror reflecting the light beam toward a surface. A graphics processing unit processes video data to compensate for a response of the light module. The response is an optical power of the light beam produced by the light module for a given forward current through the light module. A light source driver controls the light module as a function of the processed video data. Colors of the images from the video data produced on the surface by the light beam would otherwise not look as they are intended to look due to changing of the response of the light module, but the processing of the video data alters the video data such that the colors of the images from the video data produced on the surface look as they are intended to look.
