Abstract:
A photoelectric conversion apparatus comprising a photoelectric conversion element for converting an incident light signal to an electric signal, a transistor for performing a transfer control of the electric signal from the photoelectric conversion element, and driving means for applying a transfer control signal having a pulse length to a control electrode of the transistor, said photoelectric conversion apparatus comprising:control means for controlling said driving means so as to detect a temperature of said photoelectric conversion element or said transistor and to cause a change in the pulse length of the transfer control signal, so that in a case where the detected temperature is higher than a reference temperature, the pulse length of the transfer control signal is made shorter relative to a pulse length corresponding to the reference temperature, thereby shortening a transfer time of the electric signal, and in a case where the detected temperature is lower than the reference temperature, the pulse length of the transfer control signal is made longer relative to the pulse length corresponding to the reference temperature, thereby lengthening the transfer time of the electric signal.
