VIDEO SIGNAL PROCESSOR AND VIDEO SIGNAL PROCESSING METHOD

摘要

A video signal processor such that the phenomenon that the noise moves upward or downward when the noise is reduced when a nonstandard signal is inputted is prevented. When a nonstandard signal is inputted as the input video signal, the factor of an interpolation filter for interpolating a pixel of the temporarily continuous field video signal is fixed as the signal processing for the nonstandard signal. In such a way, the interpolated pixels created by the interpolation are present in the same vertical spatial position, and the pixel about which the noise is reduced by these interpolated pixels are present in the same vertical space as that of the pixels before the noise reduction. Thus they are present in the same horizontal position.
