Abstract:
The present technology relates to an imaging element that can reduce noise. The imaging element includes: a photoelectric conversion element; a first amplification element that amplifies a signal from the photoelectric conversion element; a second amplification element that amplifies an output from the first amplification element; an offset element provided between the first amplification element and the second amplification element; a first reset element that resets the first amplification element; and a second reset element that resets the second amplification element. The offset element is a capacitor. A charge is accumulated in the offset element via a feedback loop of an output from the second amplification element, and an offset bias is generated. The present technology can be applied to an imaging element.
