Abstract
The present invention relates to a video signal processing device for avoiding a phenomenon that noise is upwardly or downwardly shifted due to noise reducing operation when a non-standard signal is input. When a non-standard signal is input as an input video signal, coefficients of interpolating filters for carrying out interpolation on pixels of timely-sequential field video signals are fixed as a non-standard signal supporting signal processing. With this processing, interpolated pixels achieved by the interpolation processing are located at the same vertical spatial position, and pixels which are noise-reduced by the interpolated pixels are located at the same vertical spatial position as pixels before original noise is reduced, thereby locating the pixels at the same horizontal position.
