摘要：
A solid-state image pickup element includes a pixel and a signal detecting unit. The pixel has at least two photoelectric conversion units including a first photoelectric conversion unit and a second photoelectric conversion unit in a semiconductor. The first photoelectric conversion unit has a higher impurity density than the second photoelectric conversion unit and is configured to allow the transfer of a charge occurring in the second photoelectric conversion unit to the first photoelectric conversion unit. The signal detecting unit commonly detects the charge amount in the first photoelectric conversion unit and the second photoelectric conversion unit.
