发明名称 COLOR SIGNAL REPRODUCING SYSTEM AND CIRCUIT FOR THE SAME
摘要 <p>COLOR SIGNAL REPRODUCING SYSTEM AND CIRCUIT FOR THE SAME In a television color signal reproducing circuit, a red color difference signal from a color demodulator is corrected by a blue color difference signal, and the blue color difference signal is corrected by a luminance signal. The phase of a color subcarrier signal to be supplied to the color demodulator is controlled by the corrected red color difference signal during reception of a VIR signal, and the level of a color signal to be supplied to the color demodulator is controlled by the corrected blue color difference signal. The controls of hue and color saturation are facilitated by the use of the corrected color difference signals. It is also possible to deliver from the color demodulator color difference signals which match the fluorescence characteristics of a color picture tube.</p>
