Abstract
A number of invalid pixels at an outer peripheral part is reduced while suppressing an influence on an image quality such as discontinuity by pixel expansion, and suppressing increase in a number of processing pixels. When sequentially generating a plurality of reduced images having resolutions different from each other by sequentially performing a reduction process on an input image when realizing a noise reduction process using multiresolution transformation, the pixel expansion process of expanding the pixels at the outer peripheral part of the image of the reduced image is performed at least once before performing one of the reduction processes, and the reduced image after the pixel expansion process is further reduced to generate the plurality of reduced images.
