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. A personal identification apparatus comprising:

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.

2. The personal identification apparatus according to claim 1,

wherein the plurality of light sources and the image pick-up units are respectively arranged opposite to each other in a concentric from to surround the finger inserted into the finger inlet.

3. The personal identification apparatus according to claim 1, wherein each of the image pick-up units comprises at least a camera and an optical filter.

4. The personal identification apparatus according to claim 1,

wherein the extracting and collating unit is capable to be connected to an external storage device for storing the registered blood vessel pattern and personal information corresponding to the registered blood vessel pattern.
