Outline of Final Research Achievements

This study was aimed at evaluating physiological effects by color components in video image and elucidating the mechanism of those effects.
One of main findings was that we could obtain the result to support the hypothesis that the blue light stimulates the sympathetic nervous system and the orange light stimulates the parasympathetic nervous system. However, although the blue light stimulates the sympathetic nervous system, it does not necessarily conduct insomnia, and contents of images may cause insomnia. In addition, the results indicate that the effects of the blue light can be decreased by the blue light blocking glasses.

Academic Significance and Societal Importance of the Research Achievements

映像の色成分のうち，ブルーライトについては，これまで多くの研究がなされてきたが，本研究のように，他の色成分についてもその影響を自律神経活動の側面から比較・評価した研究は少なく，学術的意義がある．
加えて，ブルーライトの影響を低減する手法の有効性を定量的に評価した点では，社会的意義が高いと考えられる．
