Abstract
A suppression circuit processes the video signal from an anti-comet tail (ACT) image pickup tube and develops a control signal indicative of illumination highlights exceeding a predetermined level. The control signal is coupled through ACT pulsing circuits to the control elements of the ACT image pickup tube to automatically enable the beam control element pulsing so as to increase the beam current only in the presence of an illumination highlight to force the recharging of the target to cathode potential in the area of the highlight.
