Abstract

PURPOSE:To secure the color balance among the components, by extracting the pulse-modulated video signal component out of the solid state pickup element, making this signal component pass through the clamping circuit based on each color component and then setting the black level of each video signal to the prescribed DC level respectively. CONSTITUTION:The pulse-modulated output signal sent from solid state pickup element 4 is delayed through delay circuit 7 and by a fixed scanning period of the charge transfer time. And the black level of the video signal component forming the delay signal is set to the prescribed DC level at the 1st clamping circuit 9; while the fixed DC level forming the modulated output signal is set through the 2nd clamping circuit 14 respectively. Furthermore, each black level is held by the 1st and 2nd sample holding circuits 17 and 23 plus 18 and 25 each in response to the sampling pulse whose phase has an inversion of 180 deg. with every scanning period. At the same time, the same color components are compounded with every scan synchronous period for the black levels of the video signals of circuits 17 and 23 plus 18 and 25 each and via the 3rd and 4th sample holding circuits 19 and 24 plus 20 and 25 each. Thus the color balance is secured for each component.
