Abstract

An imaging processing system includes one or more image capturing apparatuses, a reading unit configured to read biometric information from an authentication object person, a similarity calculation unit configured to calculate similarity based on a result of comparing biometric information read by the reading unit with true biometric information of the authentication object person, an authentication unit configured to perform authentication based on a comparison between the similarity calculated by the similarity calculation unit and a preliminarily set threshold, and a control unit configured to control, if the authentication performed by the authentication unit is successful, imaging processing, which is performed by the image capturing apparatus, based on the similarity calculated by the similarity calculation unit.

Claims

1. A control apparatus for controlling one or more image capturing apparatuses, the control apparatus comprising:

at least one processor; and

at least one memory having instructions stored thereon, which when executed by the at least one processor cause the at least one processor to;

identify an imaging object which enters an imageable area of the one or more image capturing apparatuses;

determine whether a time at which the imaging object enters the imageable area is within a time period which corresponds to the imaging object which enters the imageable area and which has been registered prior to the imaging object entering the imageable area; and

determine, according to a result of the determination of whether a time at which the imaging object enters the imageable area is included within a time period corresponding to the imaging object which enters the imageable area, whether the imaging object which enters the imageable area of the one or more image capturing apparatuses is tracked by the one image capturing apparatus or one of the more image capturing apparatuses.

2. The control apparatus according to claim 1, wherein the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

calculate the time period from a history of entry by an imaging object into the imageable area.

3. The control apparatus according to claim 2, wherein the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

determine a time period, in which the number of times of entries of the imaging object into the imageable area is equal to or greater than a predetermined number of times, as the time period, from the history of entry by the imaging object into the imageable area.

4. The control apparatus according to claim 1, wherein the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

determine the imaging object as a tracking object if a time at which the imaging object enters the imageable area is not included within the time period.

5. The control apparatus according to claim 1, wherein the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

compare a tracking object upper limit number with the number of tracking objects already tracked,

determine, if the tracking object upper limit number is greater than the number of tracking objects already tracked, the imaging object as a tracking object, and

determine, if the tracking object upper limit number is equal to the number of tracking objects already tracked, the imaging object as a tracking object, instead of one of the tracking objects already tracked.

6. The control apparatus according to claim 1, wherein the time period is set corresponding to each imaging object, and

wherein the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

store information on a group to which an imaging object belongs, and

determine that the imaging object is not tracked if a time at which another imaging object belonging to the same group as that of the imaging object enters the imageable area is included within the time period set for the another imaging object and the imaging object enters the imageable area within a predetermined time since the another imaging object enters the imageable area.

7. The control apparatus according to claim 1, the at least one memory has stored thereon further instructions, which when executed by the at least one processor, cause the at least one processor to:

perform authentication when the imaging object enters the imageable area and to identify the imaging object based on a result of the authentication.

8. A method for controlling one or more image capturing apparatuses, the method comprising:

identifying an imaging object which enters an imageable area of the one or more image capturing apparatuses;

making an entry time determination on whether a time at which the imaging object enters the imageable area is included within a time period which corresponds to the imaging object which enters the imageable area and which has been registered prior to the imaging object entering the imageable area; and

determining, according to a result of the entry time determination, whether the imaging object which enters the imageable area of the one or more image capturing apparatuses is tracked by the one image capturing apparatus or one of the more image capturing apparatuses.

10. The method according to claim 8, wherein the imaging object is determined as a tracking object if a time at which the imaging object enters the imageable area is not included within the time period.

11. The method according to claim 8, further comprising comparing a tracking object upper limit number with the number of tracking objects already tracked,

wherein if the tracking object upper limit number is greater than the number of tracking objects already tracked, the imaging object is determined as a tracking object, and

wherein if the tracking object upper limit number is equal to the number of tracking objects already tracked, the imaging object is determined as a tracking object, instead of one of the tracking objects already tracked.

12. The method according to claim 8, wherein the time period is set corresponding to each imaging object,

wherein the imaging object is determined not to be tracked if a time at which another imaging object belonging to the same group as that of the imaging object enters the imageable area is included within the time period set for the another imaging object and the imaging object enters the imageable area within a predetermined time since the another imaging object enters the imageable area.

17. The method according to claim 8, further comprising:

performing authentication when the imaging object enters the imageable area; and

identifying the imaging object based on a result of the authentication.

9. A non-transitory computer-readable storage medium containing computer-executable instructions for controlling one or more image capturing apparatuses, the medium comprising:

computer-executable instructions for identifying an imaging object which enters an imageable area of the one or more image capturing apparatuses;

computer-executable instructions for making an entry time determination on whether a time at which the imaging object enters the imageable area is included within a time period which corresponds to the imaging object which enters the imageable area and which has been registered prior to the imaging object entering the imageable area; and

computer-executable instructions for determining, according to a result of the entry time determination, whether the imaging object which enters the imageable area of the one or more image capturing apparatuses is tracked by the one image capturing apparatus or one of the more image capturing apparatuses.

13. The medium according to claim 9, wherein the imaging object is determined as a tracking object if a time at which the imaging object enters the imageable area is not included within the time period.

14. The medium according to claim 9, further comprising comparing a tracking object upper limit number with the number of tracking objects already tracked,

wherein if the tracking object upper limit number is greater than the number of tracking objects already tracked, the imaging object is determined as a tracking object, and

wherein if the tracking object upper limit number is equal to the number of tracking objects already tracked, the imaging object is determined as a tracking object, instead of one of the tracking objects already tracked.

15. The medium according to claim 9, wherein the time period is set corresponding to each imaging object,

wherein the imaging object is determined not to be tracked if a time at which another imaging object belonging to the same group as that of the imaging object enters the imageable area is included within the time period set for the another imaging object and the imaging object enters the imageable area within a predetermined time since the another imaging object enters the imageable area.
