Abstract
An imaging device includes first light sources that have first frequency characteristics; second light sources that have second frequency characteristics different from the first frequency characteristics and that are arranged in positions different from those of the first light sources; an imaging unit that generates an image of a subject by receiving light that is emitted from the first light sources and the second light sources and then reflected from an object; and an image corrector that performs color unevenness correction on the image, which is captured by the imaging unit, using correction data with which a ratio of luminance of a first image, which is captured by the imaging unit using the first light sources, with respect to luminance of a second image, which is captured by the imaging unit using the second light sources, in each area is uniform based on the first image and the second image.
