Abstract

A personal identification apparatus includes a finger inlet into which a finger inserted; an interface where the finger is introduced through the finger inlet; a plurality of light sources provided inside the interface to irradiate light to the finger from a plurality of directions; image pick-up units being respectively arranged opposite to the plurality of light sources and respectively capturing an image from light transmitted from the plurality of light sources through the finger; a unit for adjusting when the plurality of light sources transmit light onto the finger; and a unit for extracting blood vessel patterns contained in images captured by the image pick-up units from the light transmitted though the finger and collating each of the extracted blood vessel patterns with a registered blood vessel pattern for personal identification.

Claims

1. An imaging device for capturing a feature image of a finger, the device comprising:

a housing having an area for placing the finger;

a light source for irradiating a light to the finger; and

an imaging unit which can pick up feature information of a finger vein and feature information of a fingerprint to be used for personal identification with capturing the light from the finger, wherein the imaging unit can pick up both the feature information of the finger vein and the feature information of the fingerprint with placing the finger in the area only once.

2. The imaging device according to claim 1, the device further comprising:

a processing unit, which extracts a first human body information based on the feature information of the finger vein, and a second human body information based on the feature information of the fingerprint.

3. The imaging device according to claim 2, wherein the processing unit can execute the personal identification by comparing the first human body information and the second human body information with information stored in advance.

4. The imaging device according to claim 1, wherein the light source and the imaging unit are set in the housing.

5. The imaging device according to claim 1, wherein the imaging unit has an imaging device for picking up an image including the finger vein, and an input device for picking up an image including the fingerprint.

6. A personal identification device, the device comprising:

a finger arranging unit for guiding a finger in a prescribed location;

a light source for irradiating a light to the finger;

an imaging unit which can pick up the light reflected from the finger and the light penetrated through the finger; and

a processing unit which extracts human body information based on a finger vein, and human body information based on a fingerprint from feature information of the finger vein, and feature information of the fingerprint with placing the finger in the finger arranging unit only once.

7. The personal identification device according to claim 6, wherein the processing unit can execute personal identification with using the human body feature information based on the finger vein, and the human body information based on the fingerprint.

8. The personal identification device according to claim 6, wherein the imaging unit has an imaging device for picking up an image including the finger vein, and an input device for picking up an image including the fingerprint.

9. A personal identification device, the device comprising:

an image unit;

a finger arranging unit; and

a processing unit,

wherein during placing a finger in the finger arranging unit, the processing unit can extract human body information based on a finger vein, and human body information based on a fingerprint from feature information of the finger vein, and feature information of the fingerprint.

10. The personal identification device according to claim 9, wherein the imaging unit has an imaging device for picking up an image including the finger vein, and an input device for picking up an image including the fingerprint.

11. A personal identification device, the device comprising:

a common arranging unit for arranging a finger to acquire feature information of a finger vein and feature information of a fingerprint;

a box;

a light source arranged in the box; and

an imaging unit arranged in the box, wherein both of the feature information of the finger vein and the feature information of the fingerprint can be acquired with placing the finger in the common arranging unit only once.

12. The personal identification device according to claim 11, wherein the imaging unit has an imaging device for picking up an image including the finger vein, and an input device for picking up an image including the fingerprint.
