    摘要: A method for an optical fingerprint recognition, the method includes scanning a fingerprint image using a multiple scan which allows alternating a first scan condition and a second scan condition different from each other; determining whether an input fingerprint is a dry fingerprint depending on a darkness level of a fingerprint image derived from the first scan condition; and performing a fingerprint recognition using a fingerprint image derived from the first scan condition or a fingerprint image derived from the second scan condition in accordance with the determination result as to the dry fingerprint.

    摘要: An apparatus for processing a fingerprint image, the apparatus includes a noise information estimation unit configured to estimate information for a noise removal from at least two or more images recognized for a first section before a point of time when a fingerprint contact is initiated. The apparatus includes a fingerprint image acquiring unit configured to correct at least one image recognized for a predetermined time period after the completion of the fingerprint contact using the estimated information to acquire the fingerprint image.
