Information distribution apparatus, information distribution method, and information distribution program

1. An information distribution apparatus comprising:

a user information receiving unit configured to receive user information from user devices that respective users have, the user information including user-captured images captured by the respective user devices and positional information of the user devices measured by the respective user devices, and user IDs of the users;

a positional relation calculation unit configured to calculate positional relation between the users based on the positional information;

a user specifying unit configured to specify at least one user, as a specific user, from a plurality of pieces of user information;

an other user extraction unit configured to extract other users other than the specific user, wherein the other users are present near the specific user;

a related user group information generation unit configured to generate related user group information in which positional information of the user device of the specific user is associated with user-captured images, wherein the user captured images of the related user group information have been captured by each of the user devices of the other users; and

a distribution unit configured to distribute the related user group information to a communication terminal,

wherein the other user extraction unit further comprises a captured user determination unit configured to recognize the user-captured images captured by the respective user devices to specify the user, and

wherein the other user extraction unit extracts at least one other user who is within a predetermined distance from the specific user and wears the user device capturing the specific user based on the positional relation and output of the captured user determination unit.

2. The information distribution apparatus according to claim 1 , wherein the related user group information generation unit generates related user group positional information in a form in which the positional information of the user and the positional information of the other users can be displayed as symbols.

3. The information distribution apparatus according to claim 1 , wherein, when it is determined that the specific user has been captured, the distribution unit externally distributes the images of the specific user that have been captured.

4. The information distribution apparatus according to claim 1 , wherein the user specifying unit comprises a specific user ID information receiving unit configured to receive specific user ID information from an external communication terminal.

5. An information distribution method comprising:

receiving user information from user devices that respective users have, the user information including user-captured images captured by the respective user devices and positional information of the users measured by the respective user devices, and user IDs of the users;

calculating positional relation between the users based on the positional information;

specifying at least one user, as a specific user, from a plurality of pieces of user information;

extracting other users other than the specific user, wherein the other users are present near the specific user;

generating related user group information in which positional information of the user device of the specific user is associated with user-captured images, wherein the user captured images of the related user group information have been captured by each of the user devices of the other users; and

distributing the related user group information to a communication terminal,

wherein the user-captured images captured by the respective user devices are recognized to specify the user, and

wherein at least one other user who is within a predetermined distance from the specific user and wears the user device capturing the specific user is extracted based on the positional relation and results of specifying the user.

6. A non-transitory computer readable medium storing an information distribution program for causing a computer to execute following processing of:

receiving user information from user devices that respective users have, the user information including user-captured images captured by the respective user devices and positional information of the users measured by the respective user devices, and user IDs of the users;

calculating positional relation between the users based on the positional information;

specifying at least one user, as a specific user, from a plurality of pieces of user information;

extracting other users other than the specific user, wherein the other users are present near the specific user;

generating related user group information in which positional information of the user device of the specific user is associated with user-captured images, wherein the user-captured images of the related user group information have been captured by each of the user devices of the other users; and

distributing the related user group information to a communication terminal,

wherein the user-captured images captured by the respective user devices are recognized to specify the user, and

wherein at least one other user who is within a predetermined distance from the specific user and wears the user device capturing the specific user is extracted based on the positional relation and results of specifying the user.
