Abstract

See full text

In an apparatus including an irradiation unit capable of irradiating a sheet with at least either visible light or ultraviolet light, and an acquisition unit which acquires a spectral reflectance for each of a plurality of wavelength regions based on light reflected by the sheet, a spectral reflectance acquired by the acquisition unit when the sheet is irradiated with the visible light is stored in a memory unit. A storing unit stores, in the memory unit, a spectral reflectance in a wavelength region shorter than a predetermined wavelength among spectral reflectances acquired by the acquisition unit when the sheet is irradiated with both the visible light and the ultraviolet light.
