IMAGE INPUT DEVICE, PERSONAL AUTHENTICATION DEVICE, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a thin-type image input device for inputting an image of an object which is in a living body as an image with high quality, and a thin-type personal authentication device using the input device.

SOLUTION: The image input device has an photographing optical system 100 consisting of a near-infrared ray light source 6, an optical band-pass filter for transmitting near-infrared ray, a lens array 3 in which a plurality of plane-convex lenses 3a of which the convex surfaces face an imaging face side are array-arranged and an imaging element 5 for photographing compound-eye image of an object in a living body 2a to be focused with the lens array 3. A single image is restructured by using parallax among ommatidium images from a compound-eye image in which a plurality of compound images photographed at a plurality of different positions while moving the imaging element 5 at least in a direction of an arrow 15.
