Abstract

A disclosed capture device for biometrics authentication using an image of a person'"'"'s palm includes an image sensor capturing the person'"'"'s palm and acquiring an image of the person'"'"'s palm and a guide member supporting the person'"'"'s palm when the person'"'"'s palm is captured by the image sensor. Further, the guide member has a V-shaped-type groove in which a finger of the person'"'"'s palm is to be inserted.

Claims

1. A capture device for biometrics authentication using an image of a person'"'"'s palm, the capture device comprising:

an image sensor configured to capture the person'"'"'s palm and acquire an image of the person'"'"'s palm; and

a guide member configured to support the person'"'"'s palm when the person'"'"'s palm is captured by the image sensor, wherein

the guide member has a V-shaped-type groove in which a finger of the person'"'"'s palm is to be inserted.

2. The capture device for biometrics authentication according to claim 1, further comprising:

a guide member mounted near the image sensor and configured to support a wrist of the person'"'"'s palm when the image of the person'"'"'s palm is captured by the image sensor.

3. The capture device for biometrics authentication according to claim 1, wherein

the V-shaped-type groove of the guide member is configured so that, when the person'"'"'s palm is captured by the image sensor and while the finger of the person'"'"'s palm is being inserted in the V-shaped-type groove, a distance between the person'"'"'s palm and the image sensor is automatically adjusted in accordance with a size of the person'"'"'s palm.

4. The capture device for biometrics authentication according to claim 3, wherein

the configuration where the distance between the person'"'"'s palm and the image sensor is automatically adjusted in accordance with the size of the person'"'"'s palm is achieved by a configuration that a distance between the person'"'"'s palm and the image sensor is in substantially proportion to the size of the person'"'"'s palm.

11. A biometrics authentication device comprising:

a capture device for biometrics authentication according to claim 1.

5. A capture device for biometrics authentication using an image of a person'"'"'s palm, the capture device comprising:

an image sensor configured to capture the person'"'"'s palm and acquire an image of the person'"'"'s palm; and

a guide member configured to support the person'"'"'s palm when the person'"'"'s palm is captured by the image sensor, wherein

the guide member is configured so that, when the person'"'"'s palm is captured by the image sensor and while the finger of the person'"'"'s palm is being supported by the guide member, a distance between the person'"'"'s palm and the image sensor is automatically adjusted in accordance with a size of the person'"'"'s palm.

6. The capture device for biometrics authentication according to claim 5, wherein

the configuration that the distance between the person'"'"'s palm and the image sensor is automatically adjusted in accordance with the size of the person'"'"'s palm is achieved by a configuration that a distance between the person'"'"'s palm and the image sensor is in substantially proportion to the size of the person'"'"'s palm.

12. A biometrics authentication device comprising:

a capture device for biometrics authentication according to claim 5.

7. A capture device for biometrics authentication using an image of a person'"'"'s body part, the capture device comprising:

an image sensor configured to capture the person'"'"'s body part and acquire an image of the person'"'"'s body part; and

a guide member configured to support the person'"'"'s body part when the person'"'"'s body part is captured by the image sensor, wherein

the guide member is configured so that, when the person'"'"'s body part is captured by the image sensor and while the person'"'"'s body part is being supported by the guide member, a distance between the person'"'"'s body part and the image sensor is automatically adjusted in accordance with a size of the person'"'"'s body part.

8. The capture device for biometrics authentication according to claim 7, wherein

the configuration that the distance between the person'"'"'s body part and the image sensor is automatically adjusted in accordance with the size of the person'"'"'s body is achieved by a configuration that a distance between the person'"'"'s body part and the image sensor is in substantially proportion to the size of the person'"'"'s body part.

9. The capture device for biometrics authentication according to claim 7, wherein

the person'"'"'s body part is the person'"'"'s finger.

10. The capture device for biometrics authentication according to claim 7, wherein

the person'"'"'s body part is the person'"'"'s wrist.

13. A biometrics authentication device comprising:

a capture device for biometrics authentication according to claim 7.
