An image processing device extracting a contrast component for each pixel of an input image by removing a low-frequency component of the input image and correcting the contrast component for each pixel based on a gain value, including: an input/output-property generating unit for generating an input/output-property curve, assuming an input contrast component which is the pre-correction contrast component as input, and an output contrast component which is the post-correction contrast component as output, which is an input/output-property curve of which the output contrast component monotonously increases as to the input contrast component; a gain properties generating unit for generating a gain property curve representing properties as to the input contrast component of the gain value for correcting the input contrast component to obtain the output contrast component based on the input/output-property curve; and a gain-value calculating unit for calculating the gain value for each pixel of the input image based on the gain property curve.
