Abstract

An imaging apparatus for authentication includes: a first imaging unit that obtains a first image used in a first authentication process by imaging a target person; a second imaging unit that obtains a second image used in a second image process by imaging the target person in an imaging range narrower than that of the first imaging unit; a drive unit that integrally drives the first imaging unit and the second imaging unit; and a drive control unit that controls the drive unit on the basis of the first image.

First claim

What is claimed is:

1. An imaging apparatus for authentication comprising:
a first imaging unit that obtains a first image used in a first authentication process by imaging a target person;
a second imaging unit that obtains a second image used in a second image process by imaging the target person in an imaging range narrower than that of the first imaging unit,
wherein the first imaging unit and the second imaging unit are disposed inside a housing;
a drive unit that integrally drives the first imaging unit and the second imaging unit to rotate around a central axis of the housing as an axis of rotation;
at least one memory storing instructions; and
at least one processor that is configured to execute instructions to control the drive unit on the basis of the first image.

2. The imaging apparatus for authentication according to claim 1 , wherein the processor detects a position of a first part in a living body of the target person from the first image, and controls the drive unit such that a second part included in the first part is included in the imaging range of the second imaging unit on the basis of the position of the first part.

3. The imaging apparatus for authentication according to claim 2 , wherein
the first part is a face of the target person, and
the second part is an iris of the target person.

4. The imaging apparatus for authentication according to claim 1 , wherein the drive unit drives the first imaging unit and the second imaging unit to rotate coaxially.

5. The imaging apparatus for authentication according to claim 1 , further comprising a cover part that at least partially covers the first imaging unit and the second imaging unit, wherein
in the cover part, a transmittance of light from a side of the target person to an inside of the cover part is higher than a transmittance of light from the inside of the cover part to the side of the target person.

6. The imaging apparatus for authentication according to claim 1 , further comprising a lighting unit that applies light that becomes illumination to the target person, wherein
the drive unit integrally drives the first imaging unit, the second imaging unit and the lighting unit.

7. The imaging apparatus for authentication according to claim 6 , wherein the lighting unit applies near-infrared light.

8. The imaging apparatus for authentication according to claim 7 , wherein the lighting unit has a visible light filter having a low transmittance of visible light.

9. An authentication system comprising:
a first imaging unit that obtains a first image used in a first authentication process by imaging a target person;
a second imaging unit that obtains a second image used in a second image process by imaging the target person in an imaging range narrower than that of the first imaging unit,
wherein the first imaging unit and the second imaging unit are disposed inside a housing;
a drive unit that integrally drives the first imaging unit and the second imaging unit to rotate around a central axis of the housing as an axis of rotation;
at least one memory storing instructions; and
at least one processor that is configured to execute instructions to:
control the drive unit on the basis of the first image;
perform the first authentication process by obtaining the first image;
perform the second authentication process by obtaining the second image; and
output an authentication result of the target person on the basis of a processing result of the processor.

10. The imaging apparatus for authentication according to claim 2 , wherein the first imaging unit captures the first image again and the second imaging unit captures the second image, after the processor controls the drive unit such that the second part is included in the imaging range of the second imaging unit.

11. The imaging apparatus for authentication according to claim 4 , wherein
the first imaging unit and the second imaging unit are disposed inside a cylindrical housing, and
the drive unit drives the first imaging unit and the second imaging unit to rotate around a central axis of the cylindrical housing as an axis of rotation.
