Abstract
A solid-state image-taking system including a gate voltage control unitand a substrate voltage control unit, for preventing generation of a defective image such as a residual image, without increasing the read voltage. The gate voltage control unitapplies the read voltage to the gate electrodeduring the read period. The substrate voltage control unitapplies a stationary reverse bias voltage steadily to the semiconductor substrateto cause electric charge excessively stored in the light-to-electric conversion unitto overflow to a side of the semiconductor substrate, and not to the charge storage unit, and applies, during part or all of the read period, a specific reverse bias voltage that raises a potential barrier between the semiconductor substrateand the wellto be higher than a height thereof when the stationary reverse bias voltage is applied.
