Abstract: An index calculation apparatus is provided with a luminance acquiring unit, a chromaticity acquiring unit and an index calculation unit. The luminance acquiring unit is configured to acquire a luminance Y of an evaluation object of visibility. The chromaticity acquiring unit is configured to acquire a chromaticity U of the evaluation object. The index calculation unit is configured to calculate an index V expressed by following equation by using the luminance Y and the chromaticity U·V=KYU . . . (1), where K is a constant.
