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.

Video signal processor

A video signal processing apparatus processes input video signals. A video signal source supplies the input video signals carrying at least a first video signal that is an interlaced signal having 480 effective scanning lines and a second video signal that is an interlaced signal having 1080 effective scanning lines. A video signal processor converts at least the first and the second video signals into a third video signal that is a progressive signal having 1440 effective scanning lines, thus outputting the third video signal. The output third video signal may be converted into a fourth video signal that is an interlaced signal by a progressive-to-interlace converter, thus outputting the fourth video signal.
