Abstract

An association degree evaluation unit acquires pieces of position information of an image sensing apparatus at respective times within an adjacent time range to an imaging time of a designated image of those sensed by the image sensing apparatus. Furthermore, the association degree evaluation unit acquires pieces of position information of a moving object at the respective times within the adjacent time range. Then, the association degree evaluation unit calculates a similarity between routes of the image sensing apparatus and moving object based on the acquired position information group, and decides a degree of association between the designated image and moving object based on the calculated similarity. An associating unit registers information indicating the degree of association in association with the designated image.

Claims

1. An information processing apparatus comprising:

an acquisition unit configured to acquire position information of an image sensing apparatus at an imaging time of an image by the image sensing apparatus and position information of a moving object at the imaging time;

a selection unit configured to select a moving object to be registered as metadata of the image on the basis of the position information of the image sensing apparatus and the position information of the moving object; and

a registration unit configured to register information used for specifying the selected moving object as the metadata of the image.

2. The apparatus according to claim 1, wherein said registration unit associates the information, as the metadata of the image, used for specifying the selected moving object with the image to register into a memory of the information processing apparatus.

3. The apparatus according to claim 1, further comprising a display unit configured to display candidates for the moving object to be registered as the metadata of the image on the basis of the position information of the image sensing apparatus and the position information of the moving object, and wherein said selection unit selects the moving object to be registered as the metadata of the image from the candidates.

5. A non-transitory computer-readable storage medium storing a computer program for causing a computer to function as respective units of an information processing apparatus according to claim 1.

4. An information processing method comprising:

an acquisition step of acquiring position information of an image sensing apparatus at an imaging time of an image by the image sensing apparatus and position information of a moving object at the imaging time;

a selection step of selecting a moving object to be registered as metadata of the image on the basis of the position information of the image sensing apparatus and the position information of the moving object; and

a registration step of registering information used for specifying the selected moving object as the metadata of the image.
