Abstract

A photographing control device includes: a first acquiring unit that acquires a first photographed image obtained by a first photographing device; a first authentication controlling unit that causes an authentication device to perform first facial authentication of the first photographed image; a calculating unit that calculates, in the first photographed image, a proportion of an area of a facial region; a second acquiring unit that acquires a second photographed image capturing the person and obtained by a second photographing device installed within a predetermined range from the first photographing device and having a wider angle than the first photographing device, if the proportion is no smaller than a predetermined value; a second authentication controlling unit that causes the authentication device 200 to perform second facial authentication of the second photographed image; and an output unit that outputs the second photographed image to the outside.

First claim

What is claimed is:

1. A photographing control device comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
acquire a first photographed image capturing a person and obtained by a first photographing device installed at a predetermined location;
cause an authentication device storing an association between identification information and facial feature information of a predetermined person to perform first facial authentication of the first photographed image by use of the facial feature information;
calculate, if the first facial authentication has succeeded, a proportion, in the first photographed image, of an area of a facial region authenticated successfully in the first facial authentication;
acquire a second photographed image capturing the person and obtained by a second photographing device installed within a predetermined range from the first photographing device at the predetermined location and having a wider angle than that of the first photographing device, if the proportion is no smaller than a predetermined value;
cause the authentication device to perform second facial authentication of the second photographed image by use of the facial feature information;
output the second photographed image, if the second facial authentication has succeeded; and
register an association between the second photographed image and the identification information into a predetermined storage device, if the second facial authentication has succeeded.

2. The photographing control device according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
register an association of the predetermined location with the identification information and the second photographed image into the storage device, if either one of the first facial authentication or the second facial authentication has succeeded.

3. The photographing control device according to claim 1 , wherein the at least one processor is further configured to execute the instructions to:
generate a first combined image combining the first photographed image and the second photographed image, if the second facial authentication has failed,
register an association between the first combined image and the identification information into the storage device, if the second facial authentication has failed, and
output the first combined image.

4. The photographing control device according to claim 1 , wherein
a set including the first photographing device and the second photographing device is installed at a plurality of different locations, and the at least one processor is further configured to execute the instructions to:
acquire two or more images associated with the identification information from the storage device and generate a second combined image including the two or more images, if two or more locations are associated with the identification information in the storage device, and
output the second combined image.

5. A photographing control device comprising:
at least one memory storing instructions and
an association between identification information and facial feature information of a predetermined person; and
at least one processor configured to execute the instructions to:
acquire a first photographed image capturing a person and obtained by a first photographing device installed at a predetermined location;
perform first facial authentication of the first photographed image by use of the facial feature information;
calculate, if the first facial authentication has succeeded, a proportion, in the first photographed image, of an area of a facial region authenticated successfully in the first facial authentication;
acquire a second photographed image capturing the person and obtained by a second photographing device installed within a predetermined range from the first photographing device at the predetermined location and having a wider angle than that of the first photographing device, if the proportion is no smaller than a predetermined value;
perform second facial authentication of the second photographed image by use of the facial feature information;
output the second photographed image, if the second facial authentication has succeeded; and
register an association between the second photographed image and the identification information into a predetermined storage device, if the second facial authentication has succeeded.

6. A photographing control system comprising:
a first photographing device installed at a predetermined location;
a second photographing device installed within a predetermined range from the first photographing device at the predetermined location and having a wider angle than that of the first photographing device;
an authentication device including storing means configured to store an association between identification information and facial feature information of a predetermined person and authenticating means configured to perform facial authentication by use of the facial feature information; and
a photographing control device,
wherein the photographing control device is configured to
acquire a first photographed image obtained by the first photographing device and capturing a person,
cause first facial authentication of the first photographed image to be performed by use of the facial feature information,
calculate, if the first facial authentication has succeeded, a proportion, in the first photographed image, of an area of a facial region authenticated successfully in the first facial authentication,
acquire a second photographed image obtained by the second photographing device and capturing the person, if the proportion is no smaller than a predetermined value,
cause second facial authentication of the second photographed image to be performed by use of the facial feature information,
output the second photographed image, if the second facial authentication has succeeded, and
register an association between the second photographed image and the identification information into a predetermined storage device, if the second facial authentication has succeeded.

7. The photographing control system according to claim 6 , wherein the photographing control device is configured to register an association between the second photographed image and the identification information into a predetermined storage device, if the second facial authentication has succeeded.

8. A photographing control method comprising:
acquiring a first photographed image capturing a person and obtained by a first photographing device installed at a predetermined location;
causing an authentication device storing an association between identification information and facial feature information of a predetermined person to perform first facial authentication of the first photographed image by use of the facial feature information;
calculating, if the first facial authentication has succeeded, a proportion, in the first photographed image, of an area of a facial region authenticated successfully in the first facial authentication;
acquiring a second photographed image capturing the person and obtained by a second photographing device installed within a predetermined range from the first photographing device at the predetermined location and having a wider angle than that of the first photographing device, if the proportion is no smaller than a predetermined value;
causing the authentication device to perform second facial authentication of the second photographed image by use of the facial feature information;
outputting the second photographed image, if the second facial authentication has succeeded; and
register an association between
