| Outline of Final Research Achievements |
This study compared perceptual, empirical, and theoretical luminance-chromaticity distribution of object colors, and examined our hypothesis that the visual system holds and uses luminance-chromaticity distribution of object colors. The results showed correlations of luminance-chromaticity distributions between the boundary of appearance mode and the theoretical limitation of object colors, which supports our hypothesis, and indicated the boundary on a natural image and abstract image was lower in luminance than that on an abstract image. On the contribution of these results, this study supported and improved our illuminant estimation model for object color perception.
