Abstract:
An electronic device and method are disclosed. The electronic device includes a cover glass, a display panel, a fingerprint sensor, and a processor. The processor implements the method, including: obtaining, through a fingerprint sensor, a fingerprint image from an external object contacting a surface of the electronic device, detecting, using a processor, a feature point of the fingerprint image, comparing the detected feature point of the fingerprint image with a feature point of a pre-stored reference image, detecting a variation in a distance between the surface of the electronic device and the fingerprint sensor based on a result of the comparison, and recognizing the fingerprint based on the detected variation in the distance.
