Abstract
PURPOSE:To eliminate only a leaked component, by generating a signal, which has a waveform resembling a leakage clock pulse component, from an original horizontal clock pulse applied to an image pickup element and by reversing the polarity of the signal and by applying it to the input of a preamplifier circuit. CONSTITUTION:Two-phase horizontal clock pulses are applied to terminals 12 and 13 of a solid-state image pickup element 7. A signal inputted to the gate and a signal obtained by inverting and amplifying the superposed wave of the leakage clock pulse leaked from the image pickup element 7 are obtained in the drain side of an FET9. Consequently, if the signal resembling to the leaked pulses shaped from the respective 2-phase clock pulses by waveform-shaping circuits 14 and 15 is applied to the drain in the same polarity as one applied to the gate of the FET of a preamplifier circuit 8 after level adjustment, a considerable quantity of only leakage pulse components is eliminated with the signal left as it is.
