Abstract: An imaging device includes: a semiconductor substrate including a pixel region in which pixels are arranged and a peripheral region adjacent to the pixel region; an insulating layer that covers the pixel region and the peripheral region; a first electrode located on the insulating layer above the pixel region; a photoelectric conversion layer that covers the first electrode; a second electrode that covers the photoelectric conversion layer; detection circuitry located in the pixel region and connected to the first electrode; peripheral circuitry located in the peripheral region and connected to the detection circuitry; and a third electrode located on the insulating layer above the peripheral region. The second electrode extends above the peripheral region, and the second electrode includes a connection region in which the second electrode is connected to the third electrode, the connection region overlapping the peripheral circuitry in plan view.

Abstract: An imaging device includes: a pixel that outputs a pixel signal corresponding to incident light; a comparator that compares the pixel signal with a reference signal and generates an output signal that indicates a comparison result; a counter that generates a digital signal corresponding to the pixel signal by counting the number of periods until the output signal is inverted, the counter including first to fourth counter parts, each of which corresponds to one of bits included in the digital signal; a memory that stores the digital signal, the memory including first to fourth memory parts corresponding to the first to fourth counter parts; and first and second lines. The first and third counter parts are respectively connected to the first and third memory parts through the first line. The second and fourth counter parts are respectively connected to the second and fourth memory parts through the second line.

Abstract: An imaging device includes a pixel cell including: a first photoelectric converter that generates a first electrical signal; and a first signal detection circuit that detects the first electrical signal. The first signal detection circuit includes: a first transistor one of a source and a drain of which is electrically connected to the first photoelectric converter; a first capacitor having first and second ends, the first end being electrically connected to the other of the source and the drain of the first transistor, a reference voltage being applied to the second end; and a second transistor having a gate electrically connected to the first photoelectric converter. The pixel cell outputs, in one frame period, a first image signal and a second image signal in sequence, the first image signal being output when the first transistor is off, the second image signal being output when the first transistor is on.
