Abstract

Provided is a solid-state image pickup element that amplifies the difference between respective signals of a pair of pixels and enables a reduction in the number of wiring lines. The solid-state image pickup element includes an electric-charge accumulation unit, a reference reset transistor, and a readout reset transistor. The electric-charge accumulation unit accumulates electric charge transferred from a photoelectric conversion unit and generates signal voltage corresponding to the amount of the electric charge. The reference reset transistor supplies predetermined reset voltage to the electric-charge accumulation unit in a case of generating predetermined reference voltage. The readout reset transistor supplies voltage different from the reset voltage to the electric-charge accumulation unit in a case of reading out the signal voltage.
