Abstract

PURPOSE: To make a unit small-size and light-weight by obtaining pickup signals only in the scanning period constituting a picture and obtaining pickup signals with a sufficient resolution without using a high-sensitivity pickup tube.
CONSTITUTION: When switch S is turned on, control circuit CT generates control signal b on a basis of vertical synchronizing signal a throughout the scanning period constituting a picture, and as a reslt, cathode blanking circuit KB is controlled to become a regular operation state. Then, the voltage of cathode K of vidicon tube PT is changed from EV to OV to become a pickup state, and accumulated videos are sent from target T as pickup signal d.
