Outline of Final Research Achievements

For development of adaptive visual environment as an ultimate form of vision-related universal design, three research topics were tackled as follows. Firstly, a template function for haze estimation of cataract crystalline lens was obtained through subjective evaluations of visibility by pseudo-cataract observers. Secondly, a novel simulation method of dichromat color vision using a projector-camera system was developed. Thirdly, a practical method of obtaining a color transfer matrix was developed for color management system achieving a constant color perception on a display across observations under various illuminants of different colors.
