CMIを用いた光源色や鏡面反射色のテレビにおける再現に関する一検討

抄録

This paper describes an approach for reproducing illuminant colors and specular highlights on television screens using Color-Mode-Index (CMI), which is a novel evaluation index for color-appearance of reproduced colors. We quantify the lightness of color-mode boundary as CMI 100. We reveal that surface colors in nature scenes should be reproduced under CMI 100 and that the acceptable limit is CMI 110. Then we show that the mode boundary is similar to the optimal color loci. We also reveal that the preferred CMI condition for reproducing illuminant colors and specular highlights is over CMI 100 and that the most preferred condition is CMI 120-150. Then we show the examples for reproducing illuminant colors and specular highlights with realistic impression by controlling color-mode using CMI.
