摘要： Deflection control apparatus for registering the electron beam, rasters of electrostatic-deflection pick-up tubes of a three-tube color television camera includes a compensating voltage generator with inputs connected to receive horizontal and vertical sawtooth deflection signals provided from a deflection signal generator, and outputs providing compensating voltages to adjust for size, skew, and rotation. A combining circuit is provided to add the deflecting signals to the respective compensating voltages to generate adjusted compensating voltages for application to respective electrostatic deflection plates of certain ones of the tubes. For each adjusted deflecting signal, the combining circuit includes a transistor circuit having an input electrode coupled to receive the associated compensating voltage and an output electrode connected through a load resistor to an output of the deflecting signal generator. A pair of SEPP-arranged transistors are provided with their bases connected to the output electrode of the transistor circuit and with their emitters coupled together, through like-value emitter resistors, to a respective deflection plate of one of the tubes. The SEPP-configured transistors permit a high impedance to be presented to the deflection signal generator to minimize the power consumption thereof, and a low resistance to be presented to the deflection plates, to keep the latter from undesirably integrating the deflection sawtooth voltages.

摘要： In a micro-processor based automatic registration compensation system for a multi-tube color television camera, the number of correcting points is increased by interpolation of a limited number of sampled error data. The sampling of errors, and generation of respective registration compensating signals therefrom are effected twice in respect to errors in the vertical direction and four times in respect to errors in the horizontal direction for video signals from a red pick-up tube and a blue pick-up tube, respectively, relative to a video signal from a green pick-up tube. The registration compensating signals thus obtained, particularly for the horizontal errors, are desirably applied to auxiliary deflection coils provided on each of the red and blue pick-up tubes.

摘要： A deflection control circuit for a plural-tube color television camera adjusts the deflection sawtooth waves furnished to the red and blue image pickup tubes to register the images thereof with the image of the green pickup tube, and eliminate any centering, skew, rotation, or other errors. The circuit includes a pair of controllable complementary transistors, with current outputs connected together in series. 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 correction signal generator preferably formed of an integrated-circuit operational amplifier supplies a correction voltage to control terminals of the transistors so that the current through the latter changes complementarily. An adjusted output sawtooth wave is provided from the junction to the transistors to one of the red and blue pickup tubes. Because the correction signal generator operates at low voltage, such as .+-.18 V, while the sawtooth wave is provided at a high voltage, such as .+-.80 V, a level conversion circuit is interposed between the correction signal generator and the control inputs of the complementary transistors. This circuit can include a pair of complementary transistors each having its emitter and collector coupled through respective resistors to the low and high voltages. Alternatively, this circuit can include a pair of complementary common-base transistors, the low voltages being applied thereto as reference levels.
