Abstract
PURPOSE: To obtain a circuit which can compensate drop-out of the output signal of a solid image pickup element with a comparatively cheap and small-size circuit constitution by providing a charge transfer element, which delays the output signal by a prescribed time, in the output side of the solid image pickup element.
CONSTITUTION: The output electric signal from solid image pickup element 1 which converts spatial optical information of an object to a time series electric signal and outputs this time series electric signal is delayed by one horizontal scanning period by charge transfer element 7 and is supplied to sample hold circuit 9. In case of a large level difference between the input signal and the output signal of charge transfer element 7, the output signal of charge transfer element 7 just before occurrence of this level difference is held by sample hold circuit 9 on a basis of the signal, which is obtained by detecting this level difference by 11, until the level difference becomes zero approximately, and a desired video signal with drop-out of the signal compensated is outputted from sample hold circuit 9.
