Abstract
The present technology relates to an imaging element, a driving method of an imaging element, and an electronic device capable of preventing deterioration in image quality. The imaging element reads a first signal in a state where a charge holding unit is reset, reads a second signal in a state where a reset transistor is turned off, reads a third signal in a state where charges obtained by photoelectric conversion are accumulated in the charge holding unit, reads a fourth signal in a state where the charge holding unit is reset, and sets a reset signal to an intermediate voltage between an on voltage and an off voltage before the reset signal to a gate electrode of the reset transistor is switched from the on voltage to the off voltage after the first signal is read, and generates a noise signal by correlated double sampling of the first signal and the second signal, generates a data signal by correlated double sampling of the third signal and the fourth signal, and generates an output signal by correlated double sampling of the data signal and the noise signal. The present technology is applied to, for example, an imaging element.
