Abstract

PURPOSE: To automatically perform sensitivity adjustment, every frame period, by automatically producing the time determined with the CCD output signal for the pulse signal determining the charge storage time at the frame scanning period image section.
CONSTITUTION: The light input of CCD 12 consisting of the image section 21, storage section 22, and readout section 23, is made for photo electric conversion at the image section 21 to store charge, and the storage period is changed with the production timing of clear pulse CL. Further, during the frame blanking period, transfer is made to the storage section 22 in high speed and it is transferred to the readout section 23 every scanning one line period. The output read out is branched at the preamplifier 14, one is composite video signal through the addition circuit 15, and another is DC voltage in response to the pick up output signal level at the integration circuit 16 and fed to the comparator 18, where the output voltage of the circuit 16 and the triangle wave voltage produced from the circuit 13 produce the coincidence pulse. After that, the wave shape circuit 19 performs differentiation and waveshape to establish clear pulse CL and to control the stored charge in the image section 21.
