ABSTRACT:
A fingerprint image pickup device includes a light source that emits a light for transmission through a fingertip portion having a fingerprint to be photographed, an image pickup unit that picks up the light from the light source and transmitted through the subject to acquire a fingerprint image in which convex and concave parts of the fingerprint are dark and bright, respectively, and an optical system that images the light transmitted through the fingertip portion on the image pickup unit. The optical system is arranged so that a distal side of the fingertip portion is tilted, at a predetermined angle, farther away from the optical system than an opposite side, with reference to a position at which a ventral side of the fingertip portion contacts a face orthogonal to an optical axis of the optical system.
