Abstract
A video signal processor, having an input receiving unit for selectively receiving either of a baseband video signal and a composite video signal are selectively input as an input video signal thereto, a H delay unit for delaying the selected input video signal by one line period ( H), an inter-line non-correlation component extractor for extracting inter-line non-correlation components between the input video signal and the H delay signal from the H delay unit, an inter-frame non-correlation component remover for removing inter-frame non-correlation components from the selected input video signal, a first subtractor responsive to the selection of the baseband video signal for subtracting the inter-line non-correlation component from the baseband video signal processed the inter-frame non-correlation component removal at the inter-frame non-correlation component removing means to result noise-reduced baseband video signals, a second subtractor responsive to the selection of the composite video signal the inter-line non-correlation component from the input composite video signal to result a first luminance signal, and a mixer for mixing a second luminance signal resulted from the inter-frame non-correlation component removal at the inter-frame non-correlation component remover with the first luminance signal from the second subtractor at a ratio defined by a motion signal to result a motion-adaptively processed luminance signal.
