ABSTRACT:
A video signal processing apparatus and video processing method are provided, which can reduce an influence of noise and enhance fineness of the image. A signal division unit divides a video signal into a low frequency component and a high frequency component of the video signal. A signal eliminating unit eliminates a component within a magnitude range of noise from the high frequency component of the video signal output from the signal division unit. A signal combining unit combines the low frequency component of the video signal output from the signal division unit and the high frequency component of the video signal from which the component within the magnitude range of noise is eliminated.
