Abstract
Provided is a contactless fingerprint image obtaining apparatus using a mirror. The contactless fingerprint image obtaining apparatus obtains the entire region of a fingerprint using the mirror in a contactless manner. The entire region of the fingerprint includes a fingerprint region of the front direction coinciding with the optical axis of a single shooting unit, and fingerprint regions of left/right lateral sides that do not coincide with the optical axis. Accordingly, unwillingness of a user, distortion caused by contact of the user, quality reduction, which are the limitations of a related art contact type fingerprint image obtaining apparatus are solved. Simultaneously, a wide region of a fingerprint image including the lateral sides of a fingerprint that cannot be directly obtained by a related art contactless fingerprint image obtaining apparatus using only a single camera can be economically obtained.
