Paper Abstract

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. When compared with a monitor, mobile displays are unable to display images with good color fidelity due to their smaller gamut, dimmer luminance, and worse color reproduction ability related to their low power consumption. As such, the image colors displayed on a monitor and mobile display can be significantly different for the same input digital values. Thus, to solve this problem, a color matching process between a monitor and a mobile display is needed that includes both color management in a device-independent color space1 and gamut mapping to compensate for the significant gamut difference. Yet, since these procedures involve many complex arithmetic functions, simplification is required for realization in mobile devices. Accordingly, this paper proposes a color-matching look-up to simplify the complex color-matching procedures for use in a mobile display. Moreover, the performance of the proposed color-matching look-up table is evaluated with different sizes of look-up table to determine the minimum size. Color-matching experiments between a monitor and a mobile display show that the images on the mobile display reflect the monitor images better after color matching than without color matching.
