Abstract:
A photoelectric conversion element includes: a plurality of AD conversion units that convert respective analog signals representing amounts of charge stored in a plurality of light receiving elements into digital signals in parallel; and a parallel-serial conversion unit that performs parallel-serial conversion on the digital signals into which the analog signals have been converted in parallel by the AD conversion units.
