Abstract
Each of multiple pixels includes a photoelectric conversion unit. A first holding unit is configured to hold a charge generated by the photoelectric conversion unit, at a location different from location of the photoelectric conversion unit. A second holding unit is configured to hold a charge held by the first holding unit at a location different from locations of both of the first holding unit and the photoelectric conversion unit. An amplifying unit includes an input node different from the second holding unit and is configured to output a signal based on a charge transferred to the input node from the second holding unit. A first discharge unit includes a charge draining node which is electrically connected to a line where a predetermined voltage is supplied. The first discharge unit discharges a charge held by the first holding unit to the charge draining node.
