Abstract:
1. An imaging device comprising: a plurality of first light sources that have first frequency characteristics; a plurality of 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 on the basis of the first image and the second image, wherein the image corrector detects a high luminance area, in which a luminance value is a predetermined value or larger, in each area in the first image and the second image and a fake color area, in which a luminance value of any one of the first image and the second image is the predetermined value or larger and a luminance value of the other image is smaller than the predetermined value, in each area in the first image and the second image, the image corrector changes, when detecting the high luminance area, the high luminance area to color component data or display modes that represent the high luminance area, instead of the color unevenness correction, and the image corrector changes, when detecting the fake color luminance area, the fake color luminance area to color component data or display modes that represent the fake color area, instead of the color unevenness correction.
