  • Luminance/chromaticity signal separation circuit for composite video signal
    Patent number: 5134467
    Abstract: A luminance/chromaticity signal separation circuit for a composite video signal, consisting of one-line delayers, inverters, adders, multipliers, low-pass filters, subtractors, comparators, band-pass filters, and line comb filters, capable of exactly separating a luminance signal and a chromaticity signal by selectively using output signals which are adapted to vertical luminance variations.
