PROBLEM TO BE SOLVED: To prevent the ghost light produced by the stray light from proximate lenses of a compound eye optical system arranged with a plurality of the lenses in parallel. SOLUTION: The microlenses constituting an imaging sensor for forming an image by a lens array guide efficiently obliquely incident rays to photosensors by decentering light shielding metallic layers in compliance with incident angles of incident rays, and degrade the sensitivities of the rays made incident with different angles. When the inclinations between the optical axes of the adjacent lenses of the compound eyes and their respective angles of view are set under prescribed conditions, the incident angles of the ghost light made incident on the respective photosensors are made into incident angles with lower senstivity to the photosensors, by which the ghost can be prevented.
