Abstract
An imaging device includes a semiconductor substrate that includes a first impurity region having n-type conductivity; a photoelectric converter that is electrically connected to the first impurity region and that converts light into charges; a capacitor that includes a first terminal and a second terminal, the first terminal being electrically connected to the first impurity region; and a voltage supply circuit electrically connected to the second terminal. The voltage supply circuit is configured to generate a first voltage and a second voltage different from the first voltage. The first impurity region accumulates positive charges generated by the photoelectric converter.
