Color image enhancement to restore natural color by excluding the effect of exterior illumination is important in recent image processing. In this paper, a color image enhancement method based on Land's color constancy is proposed. Since the color constancy processing preserves only hue while reducing the dynamic range of lightness and saturation, the technique of dynamic range increase in the IHS coordinate system is used for compensation. The proposed method increases lightness and saturation simultaneously.
