Abstract

PURPOSE:To achieve a prescribed stable beam control effect, by flowing a beam current neutralizing charge image, even if the incident light amount to a pickup tube is excessive, in a pickup tube operating device using a photoconductive type pickup tube. CONSTITUTION:With a pickup tube 10 having a diode gun and triode construction, Ib-Ic characteristics are mutually different, then a signal correcting means 11 is provided for a signal processing system applied to a beam control electrode G1 of the pickup tube, allowing to achieve a prescribed beam control effect very stably even for very greater signal current Is.
