1. A color correction method for a projector, comprising the steps of: a) projecting at least one image onto a projection surface; b) capturing color information of said at least one projected image on the projection surface; c) generating color transformation providing color appearance matching based on color information of an input image and the color information of said at least one projected image; and d) transforming color of the input image according to the color transformation to produce a corrected-color image to be outputted to the projector.
