A study on color conversion for the anomalous trichromat to identify color

The sensitivity of the M-cones and L-cones of an anomalous trichromat is lower than that of normal trichromats. By intensifying the light to the cones with lower sensitivity, the output ratio from the cone approached the level of a normal trichromat, and it was presumed that achieving close to original color recognition was a possibility. In order to increase luminous intensity, in the LMS space, the boundary was set as the plane surface representing pseudoisochromatic color, and the distance from that plane was expanded. When making large changes in light intensity near the surface representing pseudoisochromatic color, improvements in color differentiation and degree of color identification were observed. We implement this method in mobile devices (iPhone, Android phone, etc) and to evaluate the experimentation results.
