Patent ID: 7593566

Claim:
A data recognition device for intermittently specifying, from a time series of target data, predetermined recognition target data parts, the data recognition device comprising: a specifying unit that specifies a part of the target data as a focusing part; a calculating unit that calculates, with a first calculation rule defined by use of preset reference data, a degree of similarity between the focusing part and the reference data; a recognizing unit that determines, based on the degree of similarity, whether or not the focusing part is a recognition target data part; and a storing unit that stores information concerning a second calculation rule and information to specify the focusing part, the second calculation rule based on a result of the recognizing unit, when the recognizing unit determines that the focusing part is the recognition target data part, wherein at least one of the specifying unit and the calculating unit uses the information stored in the storing unit for processing a next one of the target data in the time series.
