Abstract
An apparatus includes a plurality of analog-to-digital conversion units that performs analog-to-digital conversion using ΔΣ modulation by comparing a signal output from a plurality of pixels to a reference voltage; and a plurality of supply units that supply one of a plurality of different reference voltages to each of the plurality of analog-to-digital conversion units. The plurality of supply units supply different reference voltages to adjacent analog-to-digital conversion units among the plurality of analog-to-digital conversion units.
Claims12
An apparatus comprising:
