  • Method and apparatus for detecting a noise value of a video signal
    Patent number: 8472787
    Abstract: A method for detecting a noise value of a video signal comprises the steps of determining a spatial domain difference according to a plurality of pixels of a first frame of the video signal, determining a temporal domain difference according to the pixels of the first frame of the video signal and a plurality of pixels of a second frame of the video signal, and generating a noise value of the first frame of the video signal according to the spatial domain difference and the temporal domain difference. An apparatus for detecting a noise value of a video signal performs the aforementioned method.
    Type: Grant
