Abstract:
1. A color chart processing apparatus comprising: determination illumination light specifying means for selecting a given determination illumination light, wherein a spectrum thereof is information regarding illumination light used to determine a predetermined color chart; spectrum calculating means for receiving information regarding a spectral reflection factor of each color contained in the predetermined color chart, and the information regarding the selected determination illumination light, and based on both of the received information regarding the spectral reflection factor of each color contained in the predetermined color chart, and the received information regarding the selected determination illumination light, determining a spectrum of each color contained in the predetermined color chart under the selected determination illumination light; and determination information output means for receiving a color signal of a subject, determining which color of the predetermined color chart most closely matches the color signal of the subject by comparing the spectrum of each color determined by the spectrum calculating means with the color signal of the subject, and outputting information identifying the determined color.
