Abstract

An image processing apparatus includes a component acquisition unit that acquires a chromaticity component and a luminance component from each of a process target image and a reference image, a feature quantity extraction unit that extracts a feature quantity from the chromaticity component and the luminance component of each of the process target image and the reference image, a chromaticity component adjustment unit that matches the chromaticity component of the process target image to the chromaticity component of the reference image using the feature quantity of the chromaticity component, and a luminance component adjustment unit that matches the luminance component of the process target image to the luminance component of the reference image in a non-dark region other than a dark region, and reduces an amount of adjustment in the adjustment of the dark region to be smaller than an amount of adjustment applied to the non-dark region.
