IMAGE ACQUISITION DEVICE, BIOMETRIC AUTHENTICATION DEVICE, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a thin and inexpensive image acquisition device capable of acquiring a vein pattern even under the sunlight.SOLUTION: An image acquisition device 1 includes: a pickup part 23 comprising plural photo-detectors 38; a condensation part 21 comprising plural micro-lenses 32 two-dimensionally arrayed each corresponding to each of the photo-detectors 38, for condensing light incident thereto; a light-shield part 22 disposed between the pickup part 23 and the condensation part 21 for preventing a beam cross-talk between the adjacent micro-lenses 32; and a band-pass filter 33 on a path where light from an object enters the photo-detectors 38, the filter containing amorphous silicon.
