PROBLEM TO BE SOLVED: To suppress the occurrence of a spot of strong electric field on a substrate in a period other than a read-out period.SOLUTION: A photoelectric conversion element generates a charge corresponding to the luminous energy of incident light and accumulates the generated charge therein. A transfer transistor (TRG) transfers the charge accumulated by the photoelectric conversion element. A first charge-voltage conversion unit converts the charge transferred by the transfer transistor (TRG) into a voltage. A substrate electrode of a MOS capacitor (region of a second charge-voltage conversion unit facing a gate electrode) connects to the first charge-voltage conversion unit via a connection transistor (FDG). A voltage different between a read-out period for a voltage signal, etc., converted by the first charge-voltage conversion unit and a period other than the read-out period is applied to a gate electrode of the MOS capacitor. The present disclosure can be applied, for example, to a CMOS image sensor, etc. |
