Patent ID: 8835828

Claim:
A photoelectric conversion apparatus comprising: a first photoelectric conversion element for generating a current by a photoelectric conversion; a first current amplifier for amplifying the current inputted from the first photoelectric conversion element through a first current input terminal; a first initializing unit for initializing a voltage of the first current input terminal; a first detector for detecting the voltage of the first current input terminal; a first feedback unit for feeding back the voltage detected by the first detector to the first current amplifier as a feedback signal; and a correcting unit for correcting the current amplified by the first current amplifier, wherein the correcting unit comprises a second current amplifier for amplifying a current inputted through a second current input terminal; a second initializing unit for initializing a voltage of the second current input terminal; a second detector for detecting the voltage of the second current input terminal; a second feedback unit for feeding back the voltage detected by the second detector to the second current amplifier as a feedback signal; and an arithmetic operation unit for performing an arithmetic operation based on the current amplified by the first current amplifier and the current amplified by the second current amplifier, to correct the current amplified by the first current amplifier.
