This paper analyzes spectral reflectance information in order to understand color features.Twenty-three-color image data are taken by using a monochrome CCD (Charge Coupled Device)camera through three filters: X, Y and Z filters on condition that the range of illumination islOOOlx to llOOOlx at every lOOOlx, and that a lens opening is eight types. Digital number (luminousintensity) in image data is much related to both brilliance and illumination at data acquisition.The relation between spectral reflectance information and brilliance will help extractthe difference of colors. Based on the measurements and the resulting relations, we propose acolor distinction approach due to fuzzy reasoning. The reliability of the proposed approach isdemonstrated in an experiment using the color image data that taken in a XYZ space.
