Imaging device, imaging system, and imaging method

摘要

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.

1. An imaging device comprising:
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; wherein the filter has a spectral transmittance that out of the three different spectral transmittances having characteristics of the color matching function, a spectral transmittance corresponding to red color has been linearly transformed thereinto so that a spectral waveform having two peaks has a single-peak shape.
