Abstract

A personal identification system, which uses a vein pattern of a finger, optimizes the amount of light of a light source based on a captured finger image and emphasizes the vein pattern during image processing for identification.

Claims

1. A terminal device for identifying a person using information on a living body, comprising:

a setting surface above which a hand to be identified is located in a non-contact position; and

a controlling unit for controlling the setting surface so as to output an indication by which the hand is guided into the non-contact position relative to the setting surface.

2. The terminal device according to claim 1, wherein the outputted indication is generated based on a shape of the hand and arranged to indicate setting positions between each finger of the hand.

3. The terminal device according to claim 1, further comprising a detecting means for detecting a height from the setting surface to the hand.

4. The terminal device according to claim 1, further comprising an imaging unit for imaging the hand in the non-contact position relative to the setting surface, wherein the imaging unit is arranged to image the hand in the non-contact position.

5. The terminal device according to claim 4, wherein a person is identified in accordance with an image having been obtained by the imaging unit.

8. The terminal device according to claim 2, further comprising:

an imaging unit for imaging the hand positioned relative to the setting surface, wherein the imaging unit is arranged to image the hand in the non-contact position relative to the setting surface, wherein the imaging unit is arranged to image the hand in the non-contact position.

9. The terminal device according to claim 3, further comprising:

an imaging unit for imaging the hand positioned relative to the setting surface, wherein the imaging unit is arranged to image the hand in the non-contact position relative to the setting surface, wherein the imaging unit is arranged to image the hand in the non-contact position.

6. A blood vessel pattern imaging device for imaging a blood vessel pattern of a human body, comprising:

a chassis including a setting surface above which a hand to be imaged is located in a non-contact position;

a controlling unit for controlling the setting surface so as to output an indication by which the hand is guided to the non-contact position relative to the setting surface; and

an imaging unit for imaging the hand to be imaged.

7. A device for identifying a person using information on a living body, comprising:

a chassis including a setting surface above which a hand to be imaged is located in a non-contact position;

a controlling unit for controlling the setting surface so as to output an indication by which the hand is guided to the non-contact position relative to the setting surface;

an imaging unit for imaging the hand to be imaged; and

an identification unit for identifying a person using information on a living body in an image generated by the imaging unit.
