Abstract:
A video signal processor, comprising:input means for selectively receiving either of a baseband video signal and a composite video signal are selectively input as an input video signal thereto; 1H delay means for delaying the selected input video signal by one line period (1H); inter-line non-correlation component extraction means for extracting inter-line non-correlation components between the input video signal and the 1H delay signal from the 1H delay means; inter-frame non-correlation component removing means for removing inter-frame non-correlation components from the selected input video signal; first subtraction means 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; second subtraction means 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 mixing means for mixing a second luminance signal resulted from the inter-frame non-correlation component removal at the inter-frame non-correlation component removing means with the first luminance signal from the second subtraction means at a ratio defined by a motion signal to result a motion-adaptively processed luminance signal.
