Outline of Final Research Achievements

We examined visual illusions using several approaches including experimental psychology, fMRI studies, mathematics, and animal experiments. A great progress was made in the study of color illusions. We found two different types of spatial color mixture, accompanied by the proposal of an impressive color illusion image in which observers can see either white or black in the same pattern depending on the types of spatial color mixture. Moreover, the Munker illusion, one of the strongest color illusions, can be explained in this context. Other approaches also made a progress in the study of visual illusions.

Academic Significance and Societal Importance of the Research Achievements

本研究は、錯視の研究である。錯視を研究することは、視覚そのものを研究することである。本研究においては、色の錯視の研究から、我々はモザイク(並置混色)を知覚する際に、加法混色と減法混色を区別していることがわかった。加法混色と減法混色の区別は産業的な仕様と考えられてきたが、脳の仕様でもあるということがわかった。このことは、視覚の本質を探り、それらの知識のさらなる社会的応用に向けての重要な一歩となったと考えられる。
