Video signal processor

摘要

A simplified Y/C separation circuit separates a composite video signal into a first luminance signal and a first color signal without subjecting the composite video signal to three-dimensional processing. A color demodulation circuit color-demodulates the first color signal into a first color difference signal. A three-dimensional processing portion removes an image quality debasing component by performing three-dimensional processing with respect to the first luminance signal and the first color difference signal or a second luminance signal constituting a component video signal and a second color difference signal. A selector selectively supplies the first luminance signal and the first color difference signal or the second luminance signal and the second color difference signal to the three-dimensional processing portion.
