Abstract
A photoelectric conversion unit includes a plurality of photoelectric conversion devices for receiving light from an object and storing charge corresponding to the quantity of the received light. A monitor unit outputs a monitor signal corresponding to the received light quantity from the start of the charge storage by the photoelectric conversion unit. When a predetermined time elapses from the start of the charge storage by the photoelectric conversion unit, a monitor read unit reads out the output monitor signal from the monitor unit. A time determining unit determines a charge storage end time on the basis of the monitor signal read out by the monitor read unit. When the charge storage end time determined by the time determining unit elapses, a signal read unit reads out charge signals stored in the photoelectric conversion devices of the photoelectric conversion unit.
