Abstract:
A method of recognizing a fingerprint includes generating, by using a fingerprint sensor, an input fingerprint image that is to be used when a fingerprint verification mode is executed; obtaining, from a memory, a registered fingerprint image that is generated from a finger image captured by a camera and stored in the memory prior to the generating the input fingerprint image; determining, from among partial regions of a registered fingerprint image that is obtained, a partial region of the registered fingerprint image, which is superimposed on the input fingerprint image, as a registered superimposed image; converting the registered superimposed image such that a first histogram of the registered superimposed image corresponds to a second histogram of the input fingerprint image; and determining, by comparing the registered superimposed image, which is converted, with the input fingerprint image, whether the input fingerprint image is verified.
