<p><P>PROBLEM TO BE SOLVED: To provide a noise reduction device capable of simply performing noise reduction different from position to position, on one sheet of image including noise. <P>SOLUTION: The noise reduction device comprises: an image patch aggregation generation part for generating an image patch aggregation from an image; a noise reduction processing part which performs noise reduction using parameters different with respect to each patch, on all the image patches belonging to the image patch aggregation, thereby generating denoised image patches; and an image composition part which performs image composition on all the denoised image patches generated by the noise reduction part, thereby composing a denoised image. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
