Abstract
PURPOSE: To increase the S/N for the intermittent recording of the pickup under the low luminous intensity with increment of the output level by utilizing the charge storage effect of the TV camera.
CONSTITUTION: TV camera 1 is provided to camera main body 10, and the utilization of the charge storage effect of the vidicon or the like is secured for camera 1. Thus the pickup output is supplied to mixer 5 through preamplifier 2 and then compounded with the composite synchronous signal formed through synchronous board 4 to be delivered to monitor terminal 6. At the same time, the signal of board 4 is supplied to camera 1 via blanking signal production circuit 14 and OR circuit 15, and the output of camera 1 is recorded on VTR20 intermittently. The vertical driving pulse V of board 4 is applied to counter 26 of speed selection circuit 25 provided to VTR20, and the output corresponding to the fixed field is caused at the output of decoder 27 with every period of the intermittent rcording. Thus signal recording process circuit 29 and circuit 15 are controlled, and then the S/N is increased for the intermittent recording with utilization of the charge storage effect.
