Abstract

A content processing device accumulates, at every predetermined time period, social information that defines the relationship and the degree of intimacy between users calculated based on lifelog information between the users; determines a time period when a content was generated, out of the predetermined time periods, from meta-information of the content; determines an evaluation time period from the determined time period; calculates a degree of intimacy between shared users during the evaluation time period; determines the priority of the evaluation time period according to the magnitude of the degree of intimacy; and controls output of the content generated during the evaluation time period according to the determined priority.

First claim

The invention claimed is:

1. A content processing device for processing at least one or more contents, comprising:
an input unit which receives input of the content, and designation of shared users, the shared users being at least one or more users who share the content;
a shared user information managing unit which manages shared user information relating to the shared users;
a content information managing unit which manages meta-information corresponding to the content;
a social information managing unit which calculates, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
a social information history accumulation unit which accumulates the social information at the every predetermined time period for calculating the social information; and
a priority determination unit which determines an evaluation time period out of the predetermined time periods based on the meta-information, calculates a degree of intimacy between the shared users received by the input unit during the evaluation time period based on the social information, and determines a priority of the evaluation time period according to the calculated degree of intimacy, the evaluation time period being a time period when a content was generated, wherein
the priority determination unit determines a priority of the content generated during the evaluation time period, based on a degree of intimacy between subjects included in the content generated during the evaluation time period.

2. The content processing device according to claim 1 , further comprising:
an output control unit which controls output of the content generated during the evaluation time period according to the priority determined by the priority determination unit.

3. The content processing device according to claim 2 , wherein
the output control unit presents the content to the shared user according to the priority determined by the priority determination unit.

4. The content processing device according to claim 2 , wherein
the output control unit deletes the content according to the priority determined by the priority determination unit.

5. The content processing device according to claim 2 , wherein
the output control unit transmits the content to a terminal device of the shared user according to the priority determined by the priority determination unit.

6. The content processing device according to 15 , wherein
the social information managing unit calculates the social information based on lifelog information managing an interaction history between the users.

7. The content processing device according to claim 1 , wherein
the priority determination unit calculates the degree of intimacy between the shared users during the evaluation time period, and determines that the priority of the evaluation time period is high, as the degree of intimacy increases.

8. The content processing device according to claim 1 , wherein
the priority determination unit calculates a variation of the degree of intimacy between the shared users during the evaluation time period, and determines that the priority of the evaluation time period is high, as the variation increases.

9. The content processing device according to claim 1 , further comprising:
a recognition information managing unit which manages recognition information for use in recognizing a subject included in the content; and
a content information analysis unit which analyzes the content based on the recognition information, and recognizes the subject included in the content, wherein
the priority determination unit calculates a degree of intimacy between a mutual pair as the shared users, based on degrees of intimacy of both of the mutual pair constituting the shared users, regarding the subject included in the content recognized by the content information analysis unit; and determines the priority of each of the contents generated during the evaluation time period in such a manner that the priority of a content including a larger number of the shared users whose degree of intimacy between the mutual pair is high is set to be high.

10. The content processing device according to claim 9 , wherein
the priority determination unit determines the priority of each of the contents generated during the evaluation time period in such a manner that the priority of a content whose variation of the degree of intimacy between the mutual pair is large is set to be high.

11. The content processing device according to claim 9 , wherein
the priority determination unit extracts a non-shared user out of the users whose degrees of intimacy are set in the social information, from the subject included in the content recognized by the content information analysis unit, and determines the priority of each of the contents generated during the evaluation time period in such a manner that the priority of a content including a larger number of the non-shared users whose degrees of intimacy with the shared user are high is set to be high, the non-shared user being a user other than the shared users.

12. A content processing method for implementing a content processing device which processes at least one or more contents, the method comprising:
an input step of receiving input of the content, and designation of shared users, the shared users being at least one or more users who share the content;
a shared user information managing step of managing shared user information relating to the shared users;
a content information managing step of managing meta-information corresponding to the content;
a social information managing step of calculating, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
a social information history accumulation step of accumulating the social information at the every predetermined time period for calculating the social information; and
a priority determination step of determining an evaluation time period out of the predetermined time periods based on the meta-information, calculating a degree of intimacy between the shared users received in the input step during the evaluation time period based on the social information, and determining a priority of the evaluation time period according to the calculated degree of intimacy, the evaluation time period being a time period when a content was generated, wherein
in the priority determination step, a priority of the content generated during the evaluation time period is determined based on a degree of intimacy between subjects included in the content generated during the evaluation time period.

13. A computer-readable recording medium which stores a program which causes a computer to function as a content processing device for processing at least one or more contents, the program causing the computer to function as:
a shared user information managing unit which manages shared user information relating to shared users, the shared users being at least one or more users who share the content received by an input unit;
a content information managing unit which manages meta-information corresponding to the content;
a social information managing unit which calculates, at every predetermined time period, social information that defines a relationship between the users and a degree of intimacy indicating a degree of closeness between the users in terms of a numerical value;
a social information history accumulation
