Abstract

A facial validation sensor includes an imaging element, a validating unit and a feedback unit. The validating unit performs validation of an individual to be validated based on facial image data of the individual, imaged by the imaging element, and facial image data registered in advance. The feedback unit guides a face of the individual to be within an imaging range that is imaged by the imaging element. The feedback unit is an indicator providing unit that provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging element.

Claims

1. :

A facial validation sensor comprising;

an imaging element;

a validating unit that performs validation of an individual to be validated based on facial image data of the individual, imaged by the imaging element, and facial image data registered in advance; and

a feedback unit that guides a face of the individual to be within an imaging range that is imaged by the imaging element, wherein

the feedback unit is an indicator providing unit that provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging element.

2. :

The facial validation sensor as set forth in claim 1, wherein the feedback unit is a flat mirror that reflects the face of the individual to be validated, and

a direction of a normal line of the flat mirror is coincident with the specific direction.

3. :

The facial validation sensor as set forth in claim 1, wherein

the feedback unit is a visual marker including a lenticular lens having a plurality of cylindrical lenses arranged with equal spacing and a pattern applied to the lenticular lens, and

a specific marker is viewable, as the indicator, from the specific direction.

4. :

The facial validation sensor as set forth in claim 1, wherein

the feedback unit is a linear cylindrical member and a light-emitting device that has a light source that is disposed in a vicinity of one end portion of the cylindrical member, and

an axis of the cylindrical member is coincident with the specific direction.

5. :

The facial validation sensor as set forth in claim 1, further comprising;

an optics system that is disposed between the imaging element and the individual to be validated, and provides a stereo image to the imaging element, wherein

the feedback unit is disposed adjacent to the optics system.
