Abstract

An operation of an authentication apparatus is as follows: Moving image data including a plurality of pieces of still image frame data is accepted, and the move locus of at least one person image is detected based on the moving image data. Individual determination processing of adopting at least one piece of the still image frame data as attention frame data and determining the individual corresponding to the detected move locus of the person image in the attention frame data is executed. The result of the individual determination processing is provided for predetermined authentication processing.

Claims

1. An authentication apparatus comprising:

a first unit accepting moving image data having a plurality of pieces of still image frame data;

a detection unit detecting a move locus of at least one person image based on the moving image data; and

a second unit executing individual determination processing of adopting at least one piece of the still image frame data as attention frame data and determining the individual corresponding to the detected move locus of the person image in the attention frame data, wherein a result of the individual determination processing is provided for predetermined authentication processing.

2. The authentication apparatus according to claim 1, wherein the detection unit detects at least one moving body from the moving image data, and

wherein the detection unit detects a move locus of the moving body satisfying a predetermined condition, of the detected moving bodies as a move locus of the person image.

3. The authentication apparatus according to claim 2, wherein the detection unit detects the move locus of the person image based on color information.

4. The authentication apparatus according to claim 1, further comprising:

a third unit detecting a face portion of a person from at least a part of the plurality of pieces of still image frame data, wherein the detection unit detects the move locus of the person image based on the detected face portion information.

5. An authentication method for causing a computer to execute, comprising:

accepting moving image data comprising a plurality of pieces of still image frame data;

detecting a move locus of at least one person image based on the moving image data;

executing individual determination processing of adopting at least one piece of the still image frame data as attention frame data;

determining the individual corresponding to the detected move locus of the person image in the attention frame data; and

providing a result of the individual determination processing for predetermined authentication processing.

6. An authentication computer program product for enabling a computer, comprising:

software instructions for enabling the computer to perform predetermined operations, and

a computer readable medium bearing the software instructions;

the predetermined operations including;

accepting moving image data comprising a plurality of pieces of still image frame data;

detecting the move locus of at least one person image based on the moving image data;

executing individual determination processing of adopting at least one piece of the still image frame data as attention frame data;

determining the individual corresponding to the detected move locus of the person image in the attention frame data; and

providing a result of the individual determination processing for predetermined authentication processing.
