Abstract
Spectrocolorimetric device includes a light source, a light-receiving unit, a calculation unit, a storage unit, an acquisition unit, and a conversion unit. The light-receiving unit spectroscopically disperses reflected light generated on a surface and measures a spectroscopic spectrum relating to the reflected light. The calculation unit calculates a first spectral reflectance from the spectroscopic spectrum. The storage unit stores relationship information indicating a relationship between a reflectance and a reflectance difference for each wavelength. The acquisition unit acquires reflectance difference for each wavelength between the first spectral reflectance acquired using the spectrocolorimetric device and a second spectral reflectance acquired using a destination-of-conversion spectrocolorimetric device on the basis of the first spectral reflectance and the relationship information. The conversion unit converts the first spectral reflectance into the second spectral reflectance by adding or subtracting the reflectance difference for each wavelength acquired by the acquisition unit to or from the first spectral reflectance.
