Abstract
An image processing device that corrects an image captured by an imaging sensor is capable of setting an exposure condition for each of a plurality of regions and includes an acquisition unit configured to acquire the image by setting the exposure condition for each region in the imaging sensor, a derivation unit configured, regarding a boundary between a region of interest and at least one adjacent region adjacent to the region of interest in the image, to derive a correction amount in the region of interest based on pixel values of a boundary pixel group in contact with the boundary included in the region of interest and pixel values of a boundary pixel group in contact with the boundary included in the adjacent region, and a correction unit configured to correct pixel values of pixels in the region of interest based on the derived correction amount.
