Abstract
Official abstract text for this publication.
An imaging device includes a photoelectric conversion element which photoelectrically converts incident light and generates a charge, accumulates and amplifies the charge, and outputs a photocurrent, wherein a level of an output signal when a charge which is accumulated in the photoelectric conversion element is outputted over a saturated amount of accumulable charge includes a level of an output signal of a charge of a photocurrent of DC component which is generated in the photoelectric conversion element and outputted during a readout time when the charge which is accumulated in the photoelectric conversion element is outputted.
First claim
Opening claim text (preview).
What is claimed is: 1. An imaging device comprising: a photoelectric conversion element configured to include a phototransistor that photoelectrically converts incident light and generates a charge, accumulates and amplifies the charge, and to output a photocurrent, wherein at a readout time, the phototransistor outputs an output signal including (i) a photocurrent of direct-current DC component generated in the phototransistor in response to illuminance of the incident light an…
