Abstract:
A photoelectric conversion apparatus includes: a first photoelectric conversion element generating a current by photoelectric conversion; a first current amplifying element for amplifying the current generated by the first photoelectric conversion element; a first detecting unit for detecting a reverse bias voltage value of the first photoelectric conversion element; and a first setting unit for setting the reverse bias voltage value of the first photoelectric conversion element at a first normal value based on a result of the detection by the first detecting unit, wherein the first normal value is larger than a depleting voltage of the first photoelectric conversion element.
