Image capturing apparatus, image capturing system, moving object, and semiconductor chip having signal processing circuits in two-dimensional form

An image capturing apparatus comprising:

• a first chip including a plurality of pixels;
• and
• a second chip stacked on the first chip and including a plurality of signal processing circuits arranged in a two-dimensional form,
• each of the plurality of signal processing circuits including
• a first selection circuit including a plurality of input nodes and a plurality of output nodes and configured such that a signal input from one of the pixels to one of the plurality of input nodes is selectively output to one of the plurality of output nodes,
• a plurality of amplifier circuits respectively connected to the plurality of output nodes, and
• an analog-to-digital conversion unit configured to convert a plurality of output signals output from the plurality of amplifier circuits,
• wherein the signal processing circuit includes a second selection circuit configured to select one of a plurality of output signals output from the plurality of amplifier circuits and output the selected output signal to the analog-to-digital conversion unit.
