1. An apparatus comprising:
a first substrate having a pixel area in which a plurality of pixels is arranged;
a second substrate superimposed on the first substrate and electrically connected to the first substrate;
a first processing unit for processing signals output from the plurality of pixels; and
a second processing unit for performing processing based on a calculation model on a signal output from the first processing unit, and arranged at a position different from a position at which the first processing unit is arranged,
at least part of the first processing unit and at least part of the second processing unit being disposed on either the first substrate or the second substrate,
the second substrate comprising:
a plurality of first wirings which are electrically connected to the first processing unit and which are disposed at positions so as to overlap the first processing unit when seen in a plan view, and
a plurality of second wirings which are electrically connected to the second processing unit and which are disposed at positions so as to overlap the second processing unit when seen in a plan view,
wherein the wiring density of the plurality of second wirings is higher than the wiring density of the plurality of first wirings,
the first substrate and the second substrate are connected such that a connection plane is formed as a result of a connection,
each of the plurality of first wirings and each of the plurality of second wirings each function as a connection part in the connection plane, and
in the connection plane, each of the plurality of first wirings is rectangular and each of the plurality of second wirings is circular.
