ABSTRACT:
A television pick-up tube in an image pick-up system comprises an high-frequency magnetic deflection element which deflects the electron beam perpendicularly to the line direction in the television pick-up tube. As a result, residual charge remaining between the image lines on the target face of the television pick-up tube is neutralized. Inductive coupling of the high-frequency deflection element to the power supply increases the resonance frequency of the deflection element, so that the deflection element can operate at a frequency which exceeds the video signal frequency so that it does not interfere therewith.
