Abstract
A television camera comprising a control stage and a setting stage for the beam current control of an electron beam in a pick-up tube. Via a video frequency picture signal amplifier suitable for processing the picture signal generated by the pick-up tube, the picture signal generated by the pick-up tube is superimposed via a coupling capacitor as a control voltage on the setting voltage for the control electrode of the pick-up tube. A stable beam current control without oscillations is the result.
