Sensor and sensor control method

A sensor comprising:

• a photoelectric conversion unit including a first photoelectric conversion element array and a second photoelectric conversion element array, each having an array of a plurality of photoelectric conversion elements arranged in a predetermined direction;
• a storage unit configured to store a charge generated by the photoelectric conversion unit;
• a transfer unit configured to transfer the charge generated by the photoelectric conversion unit to an outside of the sensor;
• a control unit configured to execute a transfer control for transporting unit configured to transport a charge stored in the second photoelectric conversion element array to the transfer unit via the storage unit and a transfer control for transporting unit configured to transport a charge stored in the first photoelectric conversion element array to the transfer unit via the second photoelectric conversion element array and the storage unit.

A method for controlling a sensor, wherein the sensor includes:

• a photoelectric conversion unit including a first photoelectric conversion element array and a second photoelectric conversion element array, each having an array of a plurality of photoelectric conversion elements arranged in a predetermined direction;
• a storage unit configured to store a charge that has been generated on the photoelectric conversion unit;
• and
• a transfer unit configured to transfer the charge generated by the photoelectric conversion unit to an outside of the sensor, the method comprising:
• transferring, by executing a first transfer control, a charge stored in the first photoelectric conversion element array to the second photoelectric conversion element array;
• transferring, by executing a second transfer control, a charge stored in the second photoelectric conversion element array to an outside of the sensor via the storage unit and the transfer unit;
• and
• serially executing the second transfer control, the first transfer control, and the second transfer control according to a trigger signal.
