Abstract

An image processing apparatus is intended to find, even when shooting a subject having a depth, respective reflection characteristics of portions of the subject with high accuracy, and includes a high-luminance region extraction unit which extracts high-luminance regions having a higher luminance than a predetermined threshold value in a plurality of image signals obtained by irradiating the subject with light emitted from a known light source and shooting reflected light from the subject at a plurality of viewpoints, a local region extraction unit which extracts local regions respectively most focused on in the portions of the subject using the plurality of high-luminance regions, and a reflection characteristic estimation unit which estimates a reflection characteristic of the subject using respective light source characteristics of the high-luminance regions in the local regions.
