Abstract
PURPOSE: To avoid the color attachment phenomenon which is conspicuous at the edge part of the moving subject in the reproduced picture, by negating the color false signal with the correction signal which is formed between the cathode and the signal output electrode of the pickup tube.
CONSTITUTION: The color multiplied TV signal transmitted from the signal output electrode of pickup tube CT is applied to the band erasion filter T via coupling capacitor C to eliminate the carrier frequency component in the color TV signals. Then the level and gradation of the correction signal for the color false signal are controlled through signal level adjustment/gradation correction circuit L to be set to the optimum state for negation of the color false signal. The signal the DC component of which is inserted again through DC reproduction circuit D is fed back positively to cathode K of the pickup tube in the form of the correction signal for the color false signal. As a result, the color attachment phenomenon which is conspicuout at the edge part of the moving subject in the reproduced picture can be eliminated.
