In a first reset period, electrons on a floating node shared by conversion elements are reset by a sequence of reset voltages before electrons in the first conversion element are transferred to the floating node for common use. In a second reset period, electrons on the floating node are reset by a first reset voltage after the electrons in the first photoelectric conversion element are transferred to the floating node and before electrons in the second photoelectric conversion element are transferred to the floating node. The first and the second reset periods are different in length. The first reset period includes a sub-period in which resetting is performed by a highest reset voltage of the plurality of reset voltages, and the second reset period includes a sub-period in which resetting is performed by the first reset voltage, wherein these two sub-periods are substantially equal in length. |
