Open the CIPO recordAbstract From the Canadian patent
A luminance signal is separated by a first means from an electric signal indicative of the image of an object to be televised and supplied from a color image pickup tube and a chrominance signal is separated by a second means from the same electric signal. At least a red color difference signal (R - Y) is mixed by a mixer with the luminance signal at a predetermined ratio with a polarity with which the red color separation signal is subtracted from the luminance signal. The corrected luminance signal and a plurality of color difference signals are supplied to a color encoder which then issues a composite color video signal.
