Abstract: An imaging device includes a first pixel, a second pixel, and a first voltage supply circuit. The first pixel includes a first photoelectric converter that generates signal charge by photoelectric conversion and a first signal detection circuit connected to the first photoelectric converter. The second pixel includes a second photoelectric converter that generates signal charge by photoelectric conversion and a second signal detection circuit connected to the second photoelectric converter. The first photoelectric converter includes a first pixel electrode, a first counter electrode facing the first pixel electrode, and a first photoelectric conversion layer located between the first pixel electrode and the first counter electrode. A voltage that the first voltage supply circuit applies between the first pixel electrode and the first counter electrode is switched between a plurality of voltages in part of a one-frame period excluding a readout period and a reset period of the second photoelectric converter.

Abstract: An imaging device includes a first pixel and a second pixel. The first pixel includes a first photoelectric converter that generates first signal charge by photoelectric conversion and that has sensitivity to a first wavelength range that is invisible and a first signal detection circuit connected to the first photoelectric converter. The second pixel includes a second photoelectric converter that generates second signal charge by photoelectric conversion and that has sensitivity to a second wavelength range and a second signal detection circuit connected to the second photoelectric converter. An exposure period of the second photoelectric converter does not overlap a light-emitting period of light based on lighting, the light being incident on the first photoelectric converter and having a luminescence peak in the first wavelength range. A readout period during which the second signal detection circuit reads out the second signal charge does not overlap the light-emitting period.

Abstract: An imaging device includes a semiconductor substrate, a first pixel, and second pixels adjacent to the first pixel. Each of the first pixel and the second pixels includes a first photoelectric conversion layer, a first pixel electrode, a first plug that electrically connects the semiconductor substrate and the first pixel electrode, a second photoelectric conversion layer, a second pixel electrode, and a second plug that electrically connects the semiconductor substrate and the second pixel electrode. When the imaging device is viewed in a normal direction of the semiconductor substrate, a smallest distance of distances between the first plug in the first pixel and the first plugs in the respective second pixels is smaller than a smallest distance of distances between the first plug in the first pixel and the second plugs in the first pixel and the respective second pixels.

Abstract: An imaging device includes pixels. Each of the pixels includes a first electrode, a second electrode, a photoelectric conversion layer that is located between the first electrode and the second electrode, that contains a donor semiconductor material and an acceptor semiconductor material, and that generates a pair of an electron and a hole, a first charge blocking layer located between the first electrode and the photoelectric conversion layer, a second charge blocking layer located between the second electrode and the photoelectric conversion layer, and a charge storage region that is electrically connected to the second electrode and that stores the hole. The difference between the electron affinity of the acceptor semiconductor material and the electron affinity of the first charge blocking layer is larger than the difference between the ionization potential of the donor semiconductor material and the ionization potential of the second charge blocking layer.
