摘要

An image processing device according to an aspect of the present invention includes a first illumination light distribution calculation unit that calculates an illumination light distribution on the basis of an input image, a first gradation conversion unit that performs gradation conversion by using the illumination light distribution calculated by the first illumination light distribution calculation unit, a second illumination light distribution calculation unit that calculates an illumination light distribution of an image having undergone the gradation conversion in the first gradation conversion unit, and a second gradation conversion unit that performs gradation conversion by using the second illumination light distribution calculation unit, in which a reference image region of the first illumination light distribution calculation unit is larger than a reference image region of the second illumination light distribution calculation unit.
