Abstract

An information processing apparatus includes an identifier obtaining unit configured to obtain an identifier of another apparatus, a detection unit configured to detect a predetermined object from a captured image, a feature-information obtaining unit configured, based on the obtaining identifier, to obtain feature information for specifying the predetermined object, a specifying unit configured, based on the characteristic information, to perform specifying processing for specifying the predetermined object detected by the detection unit, and a control unit configured, depending on a result of the specifying processing, to perform control not to obtain the identifier by the identifier obtaining unit.

Claims

1. An information processing apparatus comprising:

an identifier obtaining unit configured to obtain an identifier of another apparatus;

a detection unit configured to detect a predetermined object from a captured image;

a feature-information obtaining unit configured, based on the obtained identifier, to obtain feature information for specifying the predetermined object;

a specifying unit configured, based on the feature information, to perform specifying processing for specifying the predetermined object detected by the detection unit; and

a control unit configured, depending on a result of the specifying processing, to perform control not to obtain the identifier by the identifier obtaining unit.

2. The information processing apparatus according to claim 1, wherein the control unit is configured, in a case where a part of the predetermined objects that have been detected is not specified by the specifying processing, to perform control to obtain the identifier by the identifier obtaining unit.

3. The information processing apparatus according to claim 2, wherein the specification unit, to specify the part of the predetermined objects that have not been specified, based on the feature information corresponding to the newly obtained identifier, is configured to perform the specifying processing.

4. The information processing apparatus according to claim 1, wherein the control unit is configured, in a case where all of the predetermined objects that have been detected are specified by the specifying processing, to perform control not to obtain the identifier by the identifier obtaining unit.

5. The information processing apparatus according to claim 1, wherein the control unit is configured, in a case where a part of the predetermined objects that have been detected are not specified by the specifying processing and in a case where the result of the specifying processing satisfies a predetermined condition, to perform control not to obtain the identifier by the identifier obtaining unit.

6. The information processing apparatus according to claim 5, wherein the predetermined condition is based on a size or a number of the predetermined objects that have been able to be specified.

7. The information processing apparatus according to claim 1, wherein the control unit is configured to perform control not to transmit to another apparatus a message for requesting the identifier so as not to obtain the identifier by the identifier obtaining unit.

8. The information processing apparatus according to claim 1, wherein the control unit is configured to perform control not to receive the identifier transmitted from another apparatus so as not to obtain the identifier by the identifier obtaining unit.

9. The information processing apparatus according to claim 1, further comprising a measurement unit configured to measure a movement of the information processing apparatus;

wherein the identifier obtaining unit is configured, in a case where the movement measured by the measurement unit exceeds a predetermined value, to obtain an identifier of another apparatus.

10. The information processing apparatus according to claim 1, wherein the identifier obtaining unit is configured not to obtain the identifier again from another apparatus whose identifier has been already obtained.

11. The information processing apparatus according to claim 1, wherein the identifier obtaining unit is configured to broadcast an identifier obtaining request including a message to another apparatus whose identifier has been already obtained for instructing not to respond.

12. The information processing apparatus according to claim 1, further comprising a display control unit configured to display predetermined information in association with a predetermined object specified by the specifying unit.

13. A control method of an information processing apparatus, the method comprising:

obtaining an identifier of another apparatus;

detecting a predetermined object from a captured image;

obtaining, based on the obtained identifier, feature information for specifying the predetermined object;

performing, based on the feature information, specifying processing for specifying the predetermined object detected by the detecting from a captured image; and

controlling, depending on a result of the specifying processing, not to perform the obtaining the identifier.

14. A computer-readable storage medium that stores a program for causing a computer to execute a control method according to claim 13.
