Original Abstract Submitted

a photoelectric conversion apparatus comprises a pixel including a photoelectric conversion element, and configured to output two signals having different amplitudes based on incident light to the photoelectric conversion element, a sampling and holding unit configured to sample and hold each of the two signals output from the pixel, and an oversampling analog-to-digital conversion circuit configured to sequentially perform analog-to-digital conversion of each of the sampled and held signals. a period for performing analog-to-digital conversion of a signal having a smaller amplitude among the two signals is set shorter than a period for performing analog-to-digital conversion of a signal having a larger amplitude among the two signals.
