Abstract

There is provided a collation device capable of capturing a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of a half mirror. By disposing a plurality of displays with predetermined gap in the back side of the half mirror and disposing camera lenses and in this gap, it is possible to make the line of sight for viewing the display and the line of sight for imaging by the cameras be almost the same. As a result, it is possible to capture a face image suitable for collation by an imaging device while making a display suitable for collation by a display to a person in the front side of the half mirror.

First claim

The invention claimed is:

1. A collation device comprising:
a plurality of displays that are disposed at different heights in a vertical direction with a gap inside a housing of the collation device;
an imaging device that captures a face image of a user; and
a half mirror that covers the plurality of displays, wherein:
one of the plurality of displays is controlled to display information relating to a collation of the face image, and is selected according to a height of the user, and
another one of the plurality of displays is controlled to display with low luminance or in black.

2. The collation device of claim 1 ,
wherein the half mirror further covers the lens of the imaging device.

3. The collation device of claim 1 ,
wherein a plurality of lenses of the imaging device are disposed, at different heights in the vertical direction, and
at least one of the plurality of lenses is disposed in the gap between the plurality of displays.

4. The collation device of claim 1 , further comprising:
a polarizing member for polarizing a light beam obtained by the lens,
wherein the light beam polarized by the polarizing member is incident on an imaging element of the imaging device in a back side of the display.

5. The collation device of claim 1 ,
wherein a plurality of the imaging devices are disposed,
three or more displays are disposed in a vertical direction, and
lenses of the imaging devices are disposed at different heights in the vertical direction in the gaps between the displays.

6. The collation device of claim 1 , wherein,
the information relating to a collation of the face image is an image to prompt the user to direct a line of sight to a predetermined direction.

7. The collation device of claim 6 , wherein,
a face image recorded in a passport and the face image captured by the imaging device are collated, and
the one of the plurality of displays is controlled to display an image to prompt the user to input a face image recorded in a passport.

8. The collation device of claim 6 , wherein,
the collation device erases the image to prompt the user to direct a line of sight to a predetermined direction after a predetermined period of time has elapsed.

9. The collation device of claim 1 , wherein,
the information relating to a collation of the face image is information necessary to inform the user of the capturing of the face image by the imaging device.

10. The collation device of claim 1 , wherein the half mirror is a single half mirror that covers the plurality of displays.

11. The collation device of claim 1 , wherein light from the half mirror is reflected in an area of the another one of the plurality of displays.

12. The collation device of claim 1 , wherein only the information displayed by the one of the plurality of displays is displayed through the half mirror.

13. A collation device comprising:
a plurality of displays that are disposed at different heights in a vertical direction with a gap inside a housing of the collation device;
an image acquisition unit that acquires a collation target image;
an imaging device that captures a face image of a user; and
a half mirror that covers the plurality of displays, wherein:
one of the plurality of displays is controlled to display information relating to a collation of the face image,
another one of the plurality of displays is controlled to display with low luminance or in black, and
the device displays that the image is to be read by the image acquisition unit on a display closest to the image acquisition unit among the plurality of displays.

14. A collation device comprising:
a plurality of displays that are disposed at different heights in a vertical direction with a gap inside a housing of the collation device;
an image acquisition unit that acquires a collation target image;
an imaging device that captures a face image of a user; and
a half mirror that covers the plurality of displays, wherein:
one of the plurality of displays is controlled to display information relating to a collation of the face image,
another one of the plurality of displays is controlled to display with low luminance or in black,
a face image recorded in a passport and the face image captured by the imaging device are collated,
the information relating to a collation of the face image is an image to prompt the user to input a face image recorded in a passport via the image acquisition unit, and
a display of the plurality of displays closest to the image acquisition unit among the plurality of displays is selected as the one of the plurality of displays on which the information relating to a collation of the face image is to be displayed.

15. The collation device of claim 12 , wherein,
the image acquisition unit is disposed at lower position than the plurality of displays in a vertical direction, and,
the display lowest among the plurality of displays in the vertical direction is selected as the one of the plurality of displays on which the information relating to a collation of the face image is to be displayed.
