Abstract:
1. A solid state image pickup device, comprising a plurality of pixel units, each one of the plurality of pixel units including: a plurality of photoelectric conversion regions including a first and a second photoelectric conversion regions for generating carriers by photoelectric conversion and accumulating the generated carriers; a single amplifying unit for amplifying the carriers, the amplifying unit being commonly provided to at least the first and the second photoelectric conversion regions; a first transfer unit for transferring the carriers accumulated in the first photoelectric conversion region to the amplifying unit; a first carrier accumulating unit for accumulating carriers flowing out from the first photoelectric conversion region; a second transfer unit for transferring the carriers accumulated in the first carrier accumulating unit to the amplifying unit; a third transfer unit for transferring the carriers accumulated in the second photoelectric conversion region to the amplifying unit; a second carrier accumulating unit for accumulating carriers flowing out from the second photoelectric conversion region; and a fourth transfer unit for transferring the carriers accumulated in the second carrier accumulating unit to the amplifying unit.
