METHOD FOR ELIMINATING AN IMAGE SIGNAL NOISE CAPABLE OF ELIMINATING THE IMAGE SIGNAL NOISE BY ADAPTIVE FILTERING ACCORDING TO A COMPUTED FILTER COEFFICIENT, AND AN IMAGE SIGNAL PROCESSING DEVICE THEREOF

摘要

PURPOSE: A method for eliminating an image signal noise and an image signal processing device thereof are provided to extract a noise component in a partial area and estimate a filter coefficient by leaning an image which is known to have no noise.;CONSTITUTION: A classification code generating unit generates a classification code for each pixel in an input image with noise. A LUT(LookUp Table)(60) stores a filter coefficient matching to a generated classification code. A filtering unit(70) eliminates the noise of the input image by applying the filter coefficient matched to the classification code.;COPYRIGHT KIPO 2012
