An image capturing apparatus includes a plurality of unit pixels arranged in matrix and each including a plurality of photoelectric conversion portions, and an AD converter configured to receive a signal from each unit pixel via a vertical signal line and operate in the first AD conversion mode when being set in the first readout mode, and operates in the second AD conversion mode different from the first AD conversion mode when being set in the second readout mode. The first readout mode is a mode of independently outputting signals from a plurality of photoelectric conversion portions to a corresponding vertical signal line. The second readout mode is a mode of composing and outputting signals from a plurality of photoelectric conversion portions to a corresponding vertical signal line. |
