The color image reproducted on a CRT monitor does not have exactly the same color appearance as the real object under illumination. This is mainly because there is no simple formula for predicting exactly the state of chromatic adaptation to various illuminants and the color appearance of such kinds of color stimuli (object color or color monitor display).
In this study, the CIE chromatic adaptation transform, taking into account the adaptation coefficient for incomplete chromatic adaptation was applied to color image reproduction.
The color photographic images included a woman's face, which is one of the most important objects for color reproduction evaluation. As a result, the color image reproduction was easily displayed with the same color appearance as the object color under illumination, adjusting only for the adaptation coefficient for incomplete chromatic adaptation.
