In order to perform a pipeline processing on a noise filtering processing, which uses a multi-resolution noise filtering, with a few line memories, the way to select an area of a reduced image which is used by the extraction of the low-frequency noise component from the reduced image is modified. By extracting the low-frequency noise component from the area being selected by the modified way, it is possible to suppress a volume of image data which needs to be read prior to the noise filtering object pixel.
