An objective of the present invention is to reduce tone degradation of a region wherein tone is to be preserved with respect to restoration of a super-resolution image. This image processing device comprises: a weighting computation means for determining a region wherein a feature quantity of an inputted image is stored on the basis of a slope of a feature quantity of a pixel of the inputted image and the direction of the slope, and computing a weighting for reducing a regularization constraint, which is a constraint based on regularization of an image process in the region wherein the feature quantity is stored; a regularization computation means for computing, using the weighting, a regularization constraint of a high-resolution image which is restored on the basis of the inputted image; a reconstruction constraint computation means for computing a reconstruction constraint of the high-resolution image, which is a constraint based on the reconstruction; and an image restoration means for restoring the high-resolution image from the inputted image, on the basis of the regularization constraint and the reconstruction constraint. |
