A pattern recognition device (1) includes a collation vector extraction unit (823) generating an input collation vector consisting of a prescribed number of components indicating a feature of an input pattern, each component indicating 1 or 0, and a collation vector matching score determination unit (824) calculating a matching score based on an inner product of each dictionary collation vector read from a dictionary collation vector accumulation buffer (813) and the input collation vector. The input collation vector is collated with a dictionary feature vector for which matching score higher than a prescribed threshold value has been calculated, and a dictionary pattern corresponding to the dictionary collation vector determined as matching with the input collation vector based on a result of collation is read from dictionary data (811) and output.
