Abstract
A light-to-digital converter of the present invention includes: a plurality of light-to-digital conversion units each creating a first clock signal by performing delta-sigma conversion on a photodiode voltage created from an unbiased photodiode, and outputting a unit output signal obtained by synchronizing the first clock signal with a second clock signal that is a reference clock signal; and an adder outputting a digital output signal by adding up the unit output signals of the plurality of light-to-digital conversion units.
