Abstract
In recent years, many specific fields require accurate color reproduction for displays. Such fields are, for example, remote medical care, industrial design, electronic commerce, digital archives and color proofing of printed materials. Changes in chromaticity of the primary colors against the luminance level cause inaccurate color reproduction. This is a common problem in liquid crystal displays (LCDs). In this paper, we propose a method for correcting the phenomenon by using many colors conversion matrices made on the basis of the chromaticity shift of primary colors and luminance levels in the measured profile data of an LCD. Accurate color conversion was performed using the matrices, and the effectiveness of the conversion technique was confirmed. The application of the method enables reproduction of colors with accuracy three times as good as the Shaper Matrix Model. Moreover, it was achieved with a fewer matrices than that of the adaptive matrix color conversion.
