ABSTRACT:
A noise reduction system comprises an inputting unit inputting image data, and a noise reduction unit performing a process for removing noise of the image data input by the inputting unit. The noise reduction unit includes a representative value calculating unit calculating a representative value from the level values of a plurality of pixels in a predetermined direction, which include an observed pixel of the input image data, a representative value selecting unit selecting one representative value according to a predetermined condition from among a plurality of representative values which are calculated by the representative value calculating unit and correspond to a plurality of directions, and a replacing unit replacing the level value of the observed pixel with the representative value selected by the representative value selecting unit.
