  In this paper, we propose a novel multi-color balance method for reducing
color distortions caused by lighting effects. The proposed method allows us to
adjust three target-colors chosen by a user in an input image so that each
target color is the same as the corresponding destination (benchmark) one. In
contrast, white balancing is a typical technique for reducing the color
distortions, however, they cannot remove lighting effects on colors other than
white. In an experiment, the proposed method is demonstrated to be able to
remove lighting effects on selected three colors, and is compared with existing
white balance adjustments.
