Abstract:
1. An information processing apparatus for detecting, from time-sequential information continuously supplied for a given period of time, associated information regarding a time at which a piece of information satisfying a predetermined condition is supplied within the given period of time, the information processing apparatus comprising: dividing means for dividing the time-sequential information into a plurality of temporally successive information units at predetermined time intervals; feature value detecting means for processing in parallel the plurality of temporally successive information units for temporally successively detecting feature values of the plurality of temporally successive information units; and change-information detecting means for storing the feature values temporally successively detected by the feature value detecting means for a predetermined period of time and detecting a plurality of temporally successive pieces of feature-value-change information on the basis of the stored feature values and a current feature value detected by the feature value detecting means, wherein the change-information detecting means outputs the plurality of temporally successive pieces of feature-value-change information in sequence to output time-sequential associated information as the associated information, wherein the dividing means divides the time-sequential information into a plurality of temporally successive information units to be supplied to the feature value detecting means so that the N-th information unit and (N+1)-th information unit of the plurality of temporally successive information units are supplied to partially temporally overlap each other by an amount corresponding to the predetermined period of time during which the change-information detecting means stores the feature values.
