A method and device for fingerprint identification implementing precise identification at a high speed by using partial images of a fingerprint obtained through relative movements of a finger to a small sized sensor are provided. The device includes a frame input unit for inputting a partial image of a fingerprint. A registered image optimum position calculating unit compares the partial image to a registered fingerprint and an image combining unit creates a composite of the partial images using the optimum position. A fingerprint collating unit judges the similarity between the composite image and registered fingerprint to determine the correlation between the partial images and the registered fingerprint. |
