Abstract
An imaging device includes: a filter formed of four different filter regions with four different spectral transmittances that three different spectral transmittances having characteristics of a color matching function and a spectral transmittance for extracting metallic black have been linearly transformed thereinto by a linear transformation matrix; and an imaging unit that takes an image of light which has come out from a subject, and has been collected by an optical system, and then has passed through the filter.
