ABSTRACT:
A white image is projected on a projection surface with a projector and color information of the white image is captured by a color sensor11. A color transformation providing color appearance matching is generated based on color space of an input image and color space on the projection surface, and is stored in a memory. The color of the input image is subjected to color correction using the color transformation. After subjected to gamma correction if necessary, the color-corrected image is output to the projector.
