<P>PROBLEM TO BE SOLVED: To provide an image processing unit, noise reduction method, program and storage medium, capable of performing noise reduction processing reflecting an edge structure in the vicinity of a pixel to be processed and obtaining a robust noise reduction result with respect to edge extraction accuracy. <P>SOLUTION: The image processing unit 100, that smoothes a notice pixel of input image data with pixel values of pixels by notice pixel around the notice pixel to reduce noise in the image data, includes: an edge extraction unit 51 that extracts an edge on the basis of the pixel values of the image data; a region determination unit 53 that determines a region to be processed where a sum of edge intensities of the pixels including the notice pixel becomes greater than or equal to a threshold; and a smoothing unit 54 that changes a smoothing intensity in accordance with a size of the region to be processed to smooth the notice pixel by region to be processed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
