Abstract
Provided is an image processing device for performing noise removal in which a plurality of noise removal actions are combined while minimizing necessary resources. The image processing device is provided with: a first frequency separation unit for separating the input image by frequency into a first low-frequency component and a first high-frequency component containing a higher-frequency component than the first low-frequency component; a second frequency separation unit for separating the first low-frequency component into a second low-frequency component and a second high-frequency component containing a higher-frequency component than the second low-frequency component; a first image transform unit for performing noise removal on the second low-frequency component and the second high-frequency component and outputting the noise-removed image as a first transformed image; and a second image transform unit for performing noise removal on the first high-frequency component and the first transformed image with less resources being allocated than those allocated to the first image transform unit, and outputting the noise-removed image as a second transformed image.
