Abstract

A solid-state imaging element includes a plurality of pixels, addition switches, and a pixel drive circuit. Each of the plurality of pixels includes a photoelectric conversion device that generates charge corresponding to incident light, a charge storage unit that stores the charge, and a reset switch that resets a potential of the charge storage unit to a predetermined reset potential supplied from a power supply line. The addition switches are connected in series in two or more stages, and each of the addition switches is disposed between the power supply line and a connection line connecting power supply line sides of the reset switches of a predetermined number of pixels. The addition switches are capable of changing, by a change in a conduction state, a region of the pixels in which addition of the charge stored in the charge storage unit is performed. The pixel drive circuit changes a conduction state of the reset switches and the addition switches in the two or more stages according to the region of the pixels in which addition of the charge is performed.
