Abstract
An ambient light adaptive color correction system and method are provided in the present invention. Firstly, a color information sensor measures color information of at least black and white reference images on a projector plane with influence of ambient light. Then a color correction information calculator calculates color correction information for color appearance matching and gamut mapping based on the measured color information and a projector profile. And after pre-calculation, an image data correction unit processes an input image according to the color correction information to produce a corrected-color image to be outputted to the projector. Accordingly, the output image displayed on the projection plane with influence of ambient light will have a close color appearance to that in the dark room.
