PROBLEM TO BE SOLVED: To provide an image processing device capable of suitably correcting brightness of an input image.SOLUTION: An image processing device 100 includes: a first analysis unit 101 for estimating first relation between an average value of brightness of original images and a correction value of brightness of correction images by single regression analysis on the basis of a plurality of original images and a plurality of correction images; a second analysis unit 102 for estimating second relation between a plurality of image feature values extracted from at least one region out of a plurality of regions obtained by dividing the original images at random and the correction value of brightness of the correction images by multiple regression analysis on the basis of the plurality of original images and the plurality of correction images; a first calculation unit 103 for calculating a first correction value corresponding to the average value of brightness of input images on the basis of the first relation; a combination unit 106 for calculating a combined correction value by combining a first correction value based on the first relation and a second correction value based on the second relation; and a correction unit 107 for correcting the brightness of the input images using the combined correction value. |
