Title
(EN) Photoelectric conversion apparatus and image pickup system
Abstract
(EN)

Provided is a photoelectric conversion apparatus including a plurality of pixels and a control unit, wherein each of the pixels includes a photoelectric conversion unit and a digital-signal output unit configured to output a digital signal based on the output of the photoelectric conversion unit, and the number of bits of the digital signal may be switched.
