Abstract:
1. A video signal processor which receives a composite video signal and a component video signal, comprising: a simplified Y/C separation circuit which separates the 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 which color-demodulates the first color signal into a first color difference signal; a three-dimensional processing portion which subjects, to three-dimensional processing, the first luminance signal and the first color difference signal or a second luminance signal and a second color difference signal which constitute the component video signal, to remove an image quality debasing component; and a selector which 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, wherein the three-dimensional processing portion comprises a mixer which mixes the first luminance signal and the first color signal, and subjects a mixed signal output from the mixer to three-dimensional processing to generate a third luminance signal from which an image quality debasing component is removed.
