Color matching between monitor and mobile display device using improved S-curve model and RGB color LUT

개선된 S-curve 모델과 RGB 칼라 참조표를 이용한 모니터와 모바일 디스플레이 장치간 색 정합

This paper proposes a color matching 3D look-up table simplifying the complex color matching procedure between a monitor and a mobile display device. In order to perform color matching, it is necessary to process color of image in the device independent color space like CIEXYZ or CIELAB. We improved the S-curve model to have smaller characterization error than tolerance error. Also, as a result of the experiments, we concluded that the color matching look-up table with 64(4$\times$4$\times$4) is the smallest size allowing characterization error to be acceptable.
