1. An electronic device comprising:
a memory;
a fingerprint sensor;
a display module; and
a processor operatively connected to the memory, the fingerprint sensor, and the display module, wherein the processor:
acquires a fingerprint image through the fingerprint sensor to perform a first fingerprint recognition operation,
if the first fingerprint recognition operation fails, acquires a first fingerprint image up to a release time of a touch for fingerprint recognition,
if the touch is released, determines whether a second fingerprint image is acquired through the fingerprint sensor for a predetermined time,
if the second fingerprint image is acquired during the predetermined time, determines whether a similarity of the first fingerprint image and the second fingerprint image is greater than or equal to a predetermined threshold, and
if the similarity between the first fingerprint image and the second fingerprint image is greater than or equal to the predetermined threshold, recognizes a fingerprint using the first fingerprint image or the second fingerprint image.
