Abstract:
1. An information processing apparatus comprising: an image pickup unit photographing a subject; a movement detecting unit detecting changes in movement of the subject photographed by the image pickup unit; a data generating unit generating first timing data relating to change timing at which the movement detecting unit detected the changes in the movement; a receiving unit receiving second timing data, which relates to change timing when movement of a subject photographed by another apparatus was detected, from the other apparatus during photographing by the image pickup unit; and a determining unit determining, based on the first timing data generated by the data generating unit and the second timing data received by the receiving unit, whether the subject photographed by the image pickup unit and the subject photographed by the other apparatus are the same or a similar subject, wherein the determining unit is operable when a difference between the change timing in the first timing data and the change timing in the second timing data is smaller than a specified value, to determine that the subject photographed by the image pickup unit and the subject photographed by the other apparatus are the same or a similar subject, wherein the first timing data and the second timing data respectively include a plurality of change timings detected at different timings within a certain period, and the determining unit compares corresponding change timings included in the first timing data and the second timing data with one another, and determines that the photographed subjects are the same or a similar subject if a proportion of incidences where a difference between the compared change timings is smaller than the specified value is larger than a specified proportion.
