A LCD Color Calibration Model Based on Gamut-Division Algorithm

Abstract:

The accuracy of color appearance of displayed image on a liquid crystal display (LCD) is the fundamental to guarantee good results in the soft proofing and cross-media color reproduction. Since the color rendering mechanism of LCDs is different from cathode-ray tube (CRT) displays, the traditional color calibration method cannot turn a very good result. In this paper, a LCD color calibration model based on gamut-division algorithm is proposed using spline method through the analysis of its color rendering mechanism. The monitor 3D gamut is firstly divided along the axis of L* in CIELAB color space according to the hue angle, and then an optimal color calibration matrix of the sub-gamut is computed with mathematical method. The experimental results show that the average color difference, the maximum color difference and hue shift are reduced compared with the traditional method.
