摘要： 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.

摘要： The present technology relates to a radiation detection apparatus that makes it possible to obtain a projection image of a radiation in a short period of time. The radiation detection apparatus includes a scintillator that emits scintillation light in response to incidence of a radiation, a pixel substrate on which a plurality of pixels each of which photoelectrically converts the scintillation light and outputs a pixel signal according to a light amount of the scintillation light is disposed in an array, a detection circuit substrate that includes an A/D (Analog to Digital) conversion unit for A/D converting the pixel signal and is stacked on the pixel substrate, and a compression unit that compresses digital data outputted from the A/D conversion unit. The present technology can be applied, for example, to an X-ray imaging apparatus that detects an X-ray to perform imaging and so forth.
