PROBLEM TO BE SOLVED: To provide a technique capable of separating a noise component and an edge component from an image with high accuracy. ! SOLUTION: An image processor for compositing an input image and a low resolution image acquired from the input image on the basis of a first composition ratio to generate a first composite image includes resolution reduction means for gradually reducing the resolution of the input image, first composition means for compositing a plurality of low resolution image having different resolution levels obtained by gradually performing resolution reduction by the resolution reduction means on the basis of a second composition ratio according to the size of an edge component included in each low resolution image to generate a second composite image, and second composition means for compositing the input image and the second composite image on the first composition ratio based on the size of the edge component included in the input image and the second composition ratio to g |
