Systems and methods of an electronic device include an imaging device and a button. The electronic device also has circuitry configured to acquire a first fingerprint image captured by the imaging device in which the button is not engaged; extract first fingerprint features from the first fingerprint image; store the first fingerprint features as a registered fingerprint image; acquire a second fingerprint image captured by the imaging device in which the button is engaged; extract second fingerprint features from the second fingerprint image; compare the first fingerprint features of the registered fingerprint image and the second fingerprint features extracted from the second fingerprint image; and calculate and store an amount of distortion of the second fingerprint image based on a result of the comparing.
