PROBLEM TO BE SOLVED: To perform a pattern recognition method extracting characteristics effective for recognition from a pattern for highly precise pattern recognition. SOLUTION: A face image recognition device 200 is constituted of a face input part 201, an input subspace creation part 202, a dictionary subspace storage part 203, a pseudo whitening matrix storage part 204, a subspace linear transformation part 205, a subspace similarity calculation part 206, and a determination part 207. Similarity is found when linear transformation of an input subspace created from a plurality of input patterns acquired from a recognition object and a previously registered dictionary subspace is carried out by a pseudo whitening matrix for extracting characteristics effective for recognition.
