PROBLEM TO BE SOLVED: To provide a color calibration calculation apparatus which can calculate coefficients for performing calibration corresponding to color reproduction with a reproduction start value given.SOLUTION: A targe reproduction start value acquisition unit 1 acquires a color value output corresponding to a reproduction start value, i.e., a color reproduction visible value, when changing a colar value given for a target output device from paper white based on a target absolute color value information. A target absolute color value information conversion unit 2 converts the target absolute color value information so that a color value corresponding to a preset reproduction start set value is a color value corresponding to a reproduction start value obtained by the targe reproduction start value acquisition unit 1. A color calibration coefficient calculation unit 3 calculates the coefficients for calibrating a color value being given to a calibration output device, from the target absolute color value information converted by the target absolute color value information conversion unit 2.
