Patent ID: 7995440

Claim:
An information processing apparatus which detects concomitant information associated with a time at which data satisfying a preset condition is supplied within a continuous period of time from input data that is temporally continuously input, the apparatus comprising: a change information detecting means for detecting information on a change in a temporally continuous characteristic quantity based on the characteristic quantity that is included in a first period's worth of input data that is temporally continuously input; an accumulation means for accumulating the characteristic quantity change information output by the change information detecting means to obtain characteristic quantity change information associated with temporally continuous input data for a second period of time longer than the first period of time; a concomitant information detecting means for detecting the concomitant information based on the characteristic quantity change information accumulated in the accumulation means; an accumulated amount identifying means for identifying the amount of characteristic quantity change information accumulated in the accumulation means; and a priority determining means for determining the priority of the process of the change information detecting means and the process of the concomitant information detecting means based on the accumulated amount identified by the accumulated amount identifying means.
