Abstract
A color management system (CMS) such as ICC
profile or sRGB space have been proposed
for color transformation and reproduction
of cross media. In such a CMS, accurate colorimetric
characterization of a display device plays
a critical role in achieving device-independent
color reproduction. In the case of a CRT,
colorimetric characterization based on a
GOG model is accurate enough for this purpose.
However, there is no effective counterpart
in liquid-crystal displays (LCDs) since the
characterization of an LCD has many difficulties,
such as channel interaction and non-constancy
of channel chromaticity. In this paper, a
new method of display characterization is
proposed which is applicable to the assessment
of color reproduction of LCDs. The proposed
method characterizes an electro-optical transfer
function considering both channel interaction
and non-constancy of channel chromaticity.
Experimental results show that the proposed
method is very effective in the colorimetry
of LCDs.
