ABSTRACT:
A three-dimensional input apparatus includes a lens L1for converting angular information about light rays from a object, a focusing element L3for focusing the light rays from the object to the vicinities of an array R of photoelectric elements, and a lens L2for performing conversion into a real image near the surface of the focusing element L3. The lens L2is present between the lens L1and focusing element L3. The array R records light as image signal sequentially. A driver portion drives the optical system and scans light ray information about the object.
