an AD conversion circuit arranged on the second substrate and configured to process the pixel signals output from the block of column-scanning circuits.

2. The imaging device according to claim 1 , wherein the row signal generation circuit is arranged on the first substrate.

3. The imaging device according to claim 2 , wherein

the plurality of connection nodes are configured as a serial peripheral interface, and

a control value controlling a timing at which a state of each of the row selection signals changes is transferred to the first substrate from the second substrate via the serial peripheral interface.

4. The imaging device according to claim 1 , wherein

each of the plurality of connection nodes is arranged at a position corresponding to each of the plurality of pixels arranged in the pixel section, or

each of the plurality of connection nodes is arranged at a position corresponding to every multiple pixels of the plurality of pixels arranged in the pixel section, or

each of the plurality of connection nodes is arranged at a position corresponding to every row of the plurality of pixels arranged in the pixel section, or
