PURPOSE:To avoid the generation of a new error signal and to execute an excellent correction, by providing a sampling hold circuit with high performance to a circuit which corrects an error signal in a video signal due to the deficiency of constituting elements of a solid-state image sensor. CONSTITUTION:A circuit correcting error signals of a solid-state image sensor 101 is provided with an element drive circuit 102 producing a drive signal (b), sampling pulse generating circuit 103 generating a sampling pulse (c), and a deficiency location designating circuit 104 generating a deficient location designating pulse (d). The video signal (a) from this element 101 is inputted to the 1st sampling hold circuit 511 and the signal (a) is in holding with a sampling pulse (e) outputted at a gate circuit 105. The output of a circuit 511 is inputted to the 2nd sampling hold circuit 512, and the output of the circuit 511 is in holding with a sampling pulse (r) delaying the output (c) at a delay circuit 502. High performance sampling is made at the circuits 511, 512 to prevent the generation of new error signals. |
