A median filtering method makes a plurality of pixel data into a block of fixed unit area which includes a central pixel and a plurality of ambient pixels adjacent to the central pixel. Pixel data within the unit area is divided into sub unit areas which are smaller than the unit area. The data value of the divided pixel data is arranged in a fixed order for each of the sub unit areas. An intermediate value is determined from the arranged pixel data in each of the sub unit areas. An average value of the intermediate values which are extracted from each of the sub unit areas, and the central pixel data is determined corresponding to the central pixel of the unit area with the average value.
