Abstract
A deflection control circuit is provided for a plural-tube color television camera for compensating the deflection sawtooth waves furnished to the red and blue image pickup tubes so that the images thereof register with the image of the green pickup tube, and any centering, skew, rotation, or other errors are eliminated. The circuit includes a pair of controllable complementary current sources, such as junction transistors, with current outputs connected together in series, and with each current source having a control terminal. An impedance is connected to the junction of the current outputs, and a sawtooth wave, furnished directly to the green pickup tube, is also supplied therethrough. A control signal generator supplies a correction voltage to the control terminals of the current sources so that the current through the latter is varied in a complementary relation. A compensated output sawtooth wave is provided from the junction of the current sources to one of the red and blue pickup tubes.
