Abstract
A photoelectric conversion apparatus is provided. The photoelectric conversion apparatus includes: a photoelectric conversion unit configured to receive incident light; a differential circuit configured to receive a first signal and a second signal, which are signals respectively corresponding to signal charges generated by the photoelectric conversion unit based on the incident light, and output a third signal indicating a difference between the first signal and the second signal; and an oversampling conversion circuit configured to perform analog-digital conversion of the third signal.
