Summary: | A vertical deflection circuit is used in a camera tube in a color television camera in which the camera tube is provided with an optical filter having an optically black part extending in parallel with a beam scanning direction of the camera tube. A vertical deflection circuit comprises a circuit for generating a saw-tooth voltage for vertical deflection, a vertical deflection coil for the camera tube, and a circuit for supplying the saw-tooth voltage thus generated to one end of the vertical deflection coil in DC coupling. Due to temperature fluctuation, a vertical deflection width fluctuates with respect to a position corresponding to a black part of the filter, as a reference. |
