Abstract:
An imaging device includes a plurality of unit pixels or pixels, with each pixel separated from every other unit pixel by an isolation structure. Each unit pixel includes a photoelectric conversion unit, a pixel imaging signal readout circuit, and an address event detection readout circuit. A first transfer transistor selectively connects the photoelectric conversion unit to the pixel imaging signal readout circuit, and a second transfer transistor selectively connects the photoelectric conversion unit to the address event detection readout circuit. The photoelectric conversion unit, the pixel imaging signal readout circuit, the address event detection readout circuit, and the first and second transfer transistors for a given pixel are located within a pixel area defined by the isolation structure. The isolation structure may be in the form of a full thickness dielectric trench isolation structure.
