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 device;

a validating processor validating an individual to be validated based on facial image data of the individual, imaged by the imaging device, and facial image data registered in advance; and

a feedback device guiding a face of the individual to be within an imaging range that is imaged by the imaging device,

wherein the feedback device provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging device,

wherein the feedback device is a flat mirror that reflects the face of the individual to be validated, and

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

2. A facial validation sensor, comprising:

an imaging device;

a validating processor validating an individual to be validated based on facial image data of the individual, imaged by the imaging device, and facial image data registered in advance; and

a feedback device guiding a face of the individual to be within an imaging range that is imaged by the imaging device,

wherein the feedback device provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging device,

wherein the feedback device 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

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

3. A facial validation sensor, comprising:

an imaging device;

a validating processor validating an individual to be validated based on facial image data of the individual, imaged by the imaging device, and facial image data registered in advance; and

a feedback device guiding a face of the individual to be within an imaging range that is imaged by the imaging device,

wherein the feedback device provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging device,

wherein the feedback device 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

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

4. A facial validation sensor, comprising:

an imaging device;

a validating processor validating an individual to be validated based on facial image data of the individual, imaged by the imaging device, and facial image data registered in advance;

a feedback device guiding a face of the individual to be within an imaging range that is imaged by the imaging device; and

an optics system disposed between the imaging device and the individual to be validated, and provides a stereo image to the imaging device,

wherein the feedback device provides an indicator that is viewable from a specific direction within the imaging range that is imaged by the imaging device, and

wherein the feedback device is disposed adjacent to the optics system.
