  • Apparatus for removing noise of video signal
    Patent number: 8023762
    Abstract: An apparatus for removing a noise of a video signal is discussed, by which a noise level can be effectively estimated to enhance an image quality of the video signal, by which the noise can be removed in a manner of effectively estimating a noise level though motion adaptive filtering, and by which blurring is prevented in the process of removing the noises.
    Type: Grant
