For the purpose of providing an image processing method for efficiently performing filtering, a local region containing a pixel of interest is defined in a plurality of modes in an original image ( 502 ); sequentially for the region in the plurality of modes, the variance of pixel values is obtained and a decision is made whether the value of the variance falls within a predetermined range ( 504, 506, 508 512, 514 ); and an image is produced using as a new pixel value for the pixel of interest an average value of pixel values of the region for which the value of the variance first falls within the range ( 508, 510, 524 ). |
