The color gamut of printing devices is generally smaller than that of imaging devices. Therefore, vivid color images cannot be reproduced on printed materials. This paper proposes a color gamut extension system for printed images by using a projector-camera system. The proposed system can capture a printed image using a video camera and extend the color gamut of the printed image by super-imposing a compensation image obtained from a projector device on the printed image. The compensation image is produced in the hue, saturation, and value (HSV) color space for iteratively adjusting the saturation and brightness values toward the boundary of the color gamut in the projector-camera system at each pixel. The feasibility of the proposed system is verified by experiments performed using real printed images.
