Lens Array and Image Sensor Including Lens Array

摘要

A thin image sensor which is capable of projecting an illuminating light for illuminating an object and has high optical performance is provided. An image sensor ( 10 ) includes: a lens array ( 11 ) including lens elements ( 11 a) arranged in an array on a plane; an imaging element ( 13 ) for converting an optical image into an electrical signal, the imaging element including imaging areas, each of which includes a plurality of photoelectric conversion sections and is operable to receive the optical image; and a light source section ( 14 ) for projecting an illuminating light for illuminating an object from which the optical images are to be formed.
