Abstract
The spectroscopic instrument includes a plurality of first lenses arranged one-dimensionally or two-dimensionally; an aperture opening provided near a focal plane of each of the plurality of first lenses; a spectroscopic unit that spectrally distribute the light that has passed through the aperture opening; and a light receiving unit that receives the light spectrally distributed by the spectroscopic unit. The image producing device includes: the spectroscopic instrument; an imaging unit that captures an image formed by an imaging optical system; and an image processing unit that acquires a lighting condition from a result of spectroscopy by the spectroscopic instrument and performs color conversion processing depending on the lighting condition on an image captured by the imaging unit.
