The human eye has three types of cone cells called L-, M-, and S-cones. These cones have sensitivity peaks at long, medium, and short wavelengths, respectively. Color vision deficiency (CVD) is the inability to distinguish between certain shades of color due to the limited function of the cones. It is important to understand how CVD patients perceive color. Since color reproduction in most of the conventional methods is based on a conversion from RGB images, it is necessary to reproduce colors from spectra in order to represent colors more accurately. In this paper, we propose a method for reproducing the color vision of CVD patients based on the stage theory, which combines trichromatic theory and opponent-color theory. The proposed method focuses on the diversity of CVD patients and can reproduce the color vision according to the severity of CVD. Furthermore, by taking into account the spectrum, the proposed method can investigate the problem of metamerism, which cannot be realized by conventional methods using RGB images. |
