METHOD FOR REDUCING NOISE USING AN INTEGRATED NOISE MODELING METHOD OF AN IMAGE SENSOR CAPABLE OF PERFORMING ACCURATE NOISE MODELING

摘要

PURPOSE: A method for reducing noise using an integrated noise modeling method is provided to perform a noise filtering operation at a bayer domain.;CONSTITUTION: An image photographing device establishes a plurality of noise models of bayer domain signals which are transmitted from an image sensor(S100). The image photographing device determines an integrated noise level based on the set noise models(S200). The image photographing device filters frame data of the bayer domain based on the set noise models(S300).;COPYRIGHT KIPO 2011
