Abstract: An imaging device includes: a semiconductor substrate; a first pixel including: a first photoelectric converter above the semiconductor substrate, including first and second electrodes and a first photoelectric conversion layer between the first and second electrodes, configured to convert incident light into first charge; and a first charge accumulation region in the semiconductor substrate, electrically connected to the second electrode; and a second pixel including a second photoelectric converter above the semiconductor substrate, including third and fourth electrodes and a second photoelectric conversion layer between the third and fourth electrodes, configured to convert incident light into second charge; and a second charge accumulation region in the semiconductor substrate, electrically connected to the fourth electrode. An area of the second electrode is greater than an area of the fourth electrode, and both the first charge accumulation region and the second charge accumulation region overlap with the second electrode in plan view.

Abstract: An imaging device includes: pixel cells arranged in a matrix having rows and columns and including first and second pixel cells in one of the columns, each pixel cell comprising a photoelectric converter and a signal detection circuit detecting an electrical signal in the photoelectric converter and outputting an output signal; first and second output signal lines through which the output signals are output from each of the first and second pixel cells, respectively; and first and second feedback circuits that form, for each of the first and second pixel cells, first and second feedback paths negatively feeding back the electrical signals, respectively. The first and second pixel cells are arranged every n rows in the one of the columns where that n is an integer equal to or greater than two, the rows respectively having the first pixel cells being different from those respectively having the second pixel cells.
