PURPOSE: To provide a fast filtering processing method for an image. CONSTITUTION: In a filter area, plural square areas D1-D3 which share mutual center parts including an aimed pixel are set. The total values of image data on respective pixels included in the square areas D1-D3 are found respectively. Further, the total values of the respective square areas are multiplied by mutually different coefficients K1.W, K2.W, and K3.W and the products are totalized to find a signal value F which is filtered. |
