Abstract:
1. A video signal processing device, characterized by comprising: interpolating means for executing interpolation processing adapted for a standard signal, the interpolation processing being executed so that when an input video signal of a video unit is a standard signal, the spatial positions of pixels in the vertical direction are made coincident between the input video signal and an input video signal that is preceding to the former input video signal by one picture unit; differential means for achieving a differential signal for the input video signal interpolatively processed by said interpolating means and the one-picture-unit preceding input video signal which is interpolatively processed by said interpolating means; noise component signal extracting means for extracting a noise component signal from the differential signal achieved by said differential means; synthesizing means for synthesizing a noise component signal for the input video signal; and judging means for judging whether the input video signal is a standard signal or non-standard signal, wherein when it is judged by said judging means that the input video signal is a standard signal, said interpolating means executes the interpolation processing adapted for the standard signal, and when it is judged by said judging means that the input video signal is a non-standard signal, said interpolating means or said noise component signal extracting means executes required processing adapted for the non-standard signal concerned.
