An imaging device comprises a solid-state image sensor including a plurality of unit pixels, and a driving unit. Each unit pixel includes a photo-electric converter that converts incident light into a signal charge, a holding unit that temporarily holds the signal charge obtained by the photo-electric converter, a first transfer gate arranged between the photo-electric converter and the holding unit, that transfers the signal charge to the holding unit, a charge-voltage converter that converts the signal charge into a voltage signal, and a second transfer gate arranged between the holding unit and the charge-voltage converter, that transfers the signal charge to the charge-voltage converter, and that is in a non-conductive state in the case where an image capturing operation is performed in the photo-electric converter. The driving unit drives the solid-state image sensor so as to supply three or more mutually different electric potentials to the first transfer gate. |
