Abstract

Color image enhancement to restore natural color by excluding the effect of the ambient illumination is important in recent image processing. In this paper, a new color image enhancement method using color constancy based on pseudo-linearly modified IHS coordinate system 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 is used to compensate them. The proposed method, which analyzes the relationship between the RGB and modified IHS coordinate system, transforms and increases lightness and saturation simultaneously to avoid the complexity in the related transformation.
