Abstract
A photoelectric conversion device includes a photoelectric conversion unit, a FD that retains signal charges, a transistor connected to the FD, a transfer transistor that controls transfer of the signal charges, a storage capacity unit connected to the photoelectric conversion unit, a reset transistor that connects the FD and a fixed potential, a storage capacity connection transistor that connects the FD and the storage capacity unit. In a first mode, the photoelectric conversion device outputs a first signal based on signal charges transferred from the photoelectric conversion unit to the FD and signal charges retained in the storage capacity unit. In a second mode, the photoelectric conversion device connects the storage capacity unit and the FD after discharging charges generated by the photoelectric conversion unit to the fixed potential, and outputs a second signal based on dark charges generated in the storage capacity unit.
