In creating a correction LUT that includes, as its data, correction values each equivalent to a difference between a color-measurement value measured by a spectroreflectometer as a reference color measurement unit and a color-measurement value measured by a spectroreflectometer as a correction-target color measurement unit, the correction LUT includes, as its argument elements, a wavelength, reflectance, a change in reflectivity relative to wavelength, obtains the correction values based on the color measurement results of color patches each corresponding to a predetermined color, and estimates a correction value at a grid point lacking the correction value based on the color measurement results.
