Patent ID: 8101899

Claim:
An apparatus comprising: a plurality of pixels each having a photoelectric conversion unit and a transfer transistor that transfers a charge of the photoelectric conversion unit; an amplification unit configured to receive the transferred charge; a scanning unit configured to supply, to a gate of the transfer transistor, a conductive pulse, a non-conductive pulse, and an intermediate-level pulse having a peak value between the conductive pulse and the non-conductive pulse; a generating unit configured to generate an image signal using a signal based on a charge transferred in response to the conductive pulse and the intermediate-level pulse; a detecting unit configured to detect a temperature; and a control unit configured to change at least one of a pulse width of the intermediate-level pulse and the peak value in accordance with information on the detected temperature, wherein the conductive pulse and the intermediate-level pulse are supplied to the transfer transistor during a light shielding period of the photoelectric conversion unit.
