US Patent 7593566 Data recognition device

A data recognition device including: a recognizing unit that specifies, out of processing target data that changes in time series, predetermined recognition target data parts from the first to the n-th in order by searching a recognition target data part from the processing target data by use of a processing parameter; a storing unit that stores, as recognition related information, a processing parameter that is used when the i-th (1≦i<n) recognition target data part is specified; and a processing parameter setting unit that generates a processing parameter to be used in recognizing the i+1-th recognition target data part and outputs the generated processing parameter to the recognizing unit.
