ABSTRACT:
The invention provides a picture signal processor comprising: a sampling circuit that receives picture signals of a plurality of standard colors separated from a video signal and samples the picture signals of the plurality of standard colors in turn repeatedly; and an interpolation filter that receives the sampling values sampled from the plurality of standard colors in the sampling circuit and finds interpolated values at a common reference interpolation time for all the standard colors by subjecting the sampling values to interpolation calculation for each standard color. The use of the interpolated values at the reference interpolation time can reduce the color blur of the color video signal.
