IMAGE PROCESSING SYSTEM, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM PRODUCT

An image processing system includes an extraction unit for extracting a local region which contains one target region and at least one or more neighborhood regions from an image signal formed of a plurality of color signals from a CCD, a vectorizing unit for obtaining vector signals which contain the plurality of the color signals as components for each of the target and the neighborhood regions, a weighting set unit for setting weighting factors with respect to each of the vector signals in the local region based on the vector signal in the target region, a filtering unit for performing a filtering process using the weighting factors with respect to the vector signals in the local region, and a noise reducing unit for reducing the noise of the vector signal in the target region based on the vector signal through the filtering process.
