光沢布地の色の見えと質感印象に対する照明の分光分布の影響

抄録

There are many studies on the texture of objects. However, the relationship between the texture impression of the fabric and the spectral distribution of the illumination light is not clear. The purpose of this research is to investigate the influence of the spectral distribution of the illumination light on the texture impression of the fabric. (1) The influence of the color on the texture impression by changing the color stimulus of the image using the fabric image was confirmed. Next, (2) the glossy fabric was observed under different light sources with different spectral distributions, and the influence of the color appearance of the fabric on the texture impression of the glossy fabric was examined. As a result, it was found that the vividness of color (chroma C*, colorfulness M) has an influence on the texture impression of the glossy fabric both in the case of the observation stimulus being the fabric image and the case of the illuminated glossy fabric.
