Abstract: An image sensor includes a semiconductor substrate having first and second faces. The sensor includes a plurality of pixel groups each including pixels, each pixel having a photoelectric converter and a wiring pattern, the converter including a region whose major carriers are the same with charges to be accumulated in the photoelectric converter. The sensor also includes a microlenses which are located so that one microlens is arranged for each pixel group. The wiring patterns are located at a side of the first face, and the plurality of microlenses are located at a side of the second face. Light-incidence faces of the regions of the photoelectric converters of each pixel group are arranged along the second face such that the light-incidence faces are apart from each other in a direction along the second face.

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.
