SPECTROMETRY DEVICE, IMAGE FORMING APPARATUS, AND SPECTROMETRY METHOD

摘要

A printer that incorporates a spectrometry device includes a spectroscope, a distance measurer, and a spectrometry unit. The spectroscope includes a wavelength-selective interference filter on which light from a position of measurement in a medium is incident. The distance measurer measures the distance between the position of measurement and the spectroscope, and the spectrometry unit performs spectrometry at the position of measurement by using the spectroscope and correct a measured value obtained by the spectrometry based on the measured distance.
