Embodiment Construction

[0043] A finger vein authentication device suitable for mounting on a small device such as a mobile phone will be described. In this finger vein authentication device, light is irradiated into the finger from a light source such as an LED (Light Emitting Diode) installed under the finger (on the belly side of the finger), and the light diffused inside the finger passes through the vein or The light reflected from the veins, etc., is affected by the internal environment of the finger including the pattern of the veins of the finger (vein pattern) and is emitted to the outside of the finger (hereinafter referred to as "transmitted light"), and an image is taken. Extract the vein pattern for personal authentication.

[0044] The imaging unit of the finger vein authentication device preferably satisfies the following optical conditions in order to clearly capture an image of the finger vein pattern. One of them is that the imaging unit does not capture infrared light reflected fr...

Abstract

The present invention provides a finger vein authentication apparatus and an information processing apparatus, the finger vein authentication apparatus comprises: a light source for emitting light toward a finger, an image sensor for taking an image of the transmitted light from the finger, a lens apparatus for imaging the transmitted light to the image sensor, and an image processor for processing the taken image. The lens apparatus (33) includes a short-focus wide field angle lens unit (38), and the image processor extracts a vein pattern of the finger upon correcting the strain of the taken image.

Description

technical field [0001] The present invention relates to a finger vein authentication device and an information processing device using the finger vein authentication device, in particular to a technique for miniaturizing the finger vein authentication device. Background technique [0002] Among various security technologies, a technology capable of high-precision authentication of finger veins is known. Finger vein authentication can achieve excellent authentication accuracy because it uses the finger vein pattern inside the body, and it is more difficult to forge and tamper than fingerprint authentication, thus achieving a high degree of security. [0003] As a conventional example of such finger vein authentication, a biometric authentication device described in JP-A-2006-155575 is known, for example. This biometric authentication device includes: a light source for irradiating light passing through a finger; an imaging unit for photographing light transmitted through the...
