| Research Abstract |
During the period of the research, a new LED-based experimental apparatus, which enables to measure the macular pigment optical density (MPOD) of the observer, was constructed. The difference in MPOD is considered to be one of the factors that mediate individual differences in color perception. MPOD was measured for many subjects, and we could successfully collect the distribution data. As a result, we could find that there is a large difference in MPOD among individual, and also its distribution showed a similar trend with those reported for the Chinese and European observers. We also tried to construct an apparatus to measure color matching functions with LEDs, and an apparatus to conduct color matching experiments using different media. Basic design and some potential problems were discussed in the research activity.
