RGB look-up table design for color matching between monitor and mobile display

摘要

This paper proposes a color-matching 3D look-up table that simplifies the complex color-matching procedure between a monitor and a mobile display device, where the image colors are processed in a device-independent color space, such as CIEXYZ or CIELAB, and gamut mapping performed to compensate the gamut difference. As such, a color-matching look-up table, which includes device characterizations and gamut mapping, is designed that is suitable for a mobile device. Experimental results demonstrated that 64 (4x4x4) was the smallest size of color-matching look-up table that could produce an image with an acceptable reproduction error, based on a comparison of color-matched images resulting from the proposed color-matching look-up table and complex step-by-step color-matching procedures.
