1. An apparatus comprising:
a first substrate having a pixel area in which a plurality of pixels are 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 a process based on a calculation model on a signal output from the first processing unit,
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,
a first path for supplying a first power supply voltage to the first processing unit being different from a second path for supplying a second power supply voltage to the second processing unit,
wherein the first power supply voltage is higher than the second power supply voltage.
