Abstract:
1. An image processing apparatus comprising: a brightness information acquisition unit that acquires brightness information indicating a brightness of each pixel in a target image from which high-frequency components are eliminated; a correction unit that corrects the brightness of each pixel indicated by the brightness information acquired by the brightness information acquisition unit by combining the brightness of each pixel indicated by the brightness information acquired by the brightness information acquisition unit with the brightness of each pixel of the target image at a given combination ratio which is predetermined in proportion to the brightness of each pixel in the target image; a correction magnification setting unit that sets, for each pixel, a correction magnification inversely proportional to the brightness of each pixel combined by the correction unit; and a gradation correction unit that corrects the brightness of each pixel by correcting a plurality of color component information of each pixel based on the correction magnification set for each pixel by the correction magnification setting unit.
