Abstract: A color correspondence information generating system includes an object database that stores correspondences between recognition information and color characteristic information about first objects recognized by the recognition information; an object recognition section that recognizes the first objects in the first image from the first image and the recognition information, and outputs image regions of the first objects in the first image and first color characteristic information; and a color correspondence information generation section that generates the color correspondence information using the color information and the first color characteristic information of pixels in the image regions. The color characteristic information and the recognition information have a one-to-one correspondence relation with each other, or the color characteristic information is the recognition information itself.
