| Outline of Final Research Achievements |
Color matching experiments were continuously conducted to analyze the effects of Intrinsically photosensitive retinal ganglion cells (ipRGCs) on the perception of reproduced images on a display set up in a natural environment. The results suggest that ipRGC affects color perception even in images on displays. Furthermore, by investigating the environment in relation to circadian rhythms, it was suggested that M1 ipRGC, a non-image forming function, may also affect color perception.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって，自然環境下に設置されたディスプレイ上においてもipRGC が色覚経路に寄与していることを示すデータが得られたことは，視覚科学の新たな学説のエビデンスとなるだけでなく，産業界のRGB の三刺激値で映像表現を行っている視覚メディアの分野において，より厳密な映像再現にはipRGCの吸収率を含めた表現が必要となることを意味しており，様々な社会実装に変革を及ぼす結果につながる．
