二つの図形の重ね合せによって生じる心理的光沢度の測定

抄録

Although there are many methods for measuring the glossiness instead of human vision, the psychological glossiness perceived by men can not be expressed enough by the use of conventional methods. When a paper drawing white figures and a paper drawing black ones are registered with half mirror, psychological glossiness may be perceived in spite of having no gloss of each paper itself. In this study, the psychological experiment is made. The paper drawing white circles and the paper drawing black ones are used as the specimen. The psychological glossiness is obtained by NAKAYA's method, which is one kind of the paired comparison method. The results are as follows. The psychological glossiness decreases as the luminance of white circles increases with the luminance of black ones low. When the luminance of black ones is high, the psychological glossiness increases, becomes a maximum, and decreases as the luminance of white ones increases. This may be explained by regarding the psychological glossiness as the sense disturbing the perception of the objects.
