Abstract
A fingerprint registration method and an electronic device using the same are provided. The fingerprint registration method includes the following steps: sequentially obtaining a plurality of swipe frames of a fingerprint by a fingerprint sensor; sequentially analyzing the swipe frames by a processor to obtain a plurality of feature points; sequentially merging the feature points of the swipe frames into pre-registration data by the processor; sequentially updating a completion area displayed on a user interface by the processor according to relative position relationships of the feature points of the swipe frames; and determining whether the pre-registration data satisfies a preset completion condition by the processor, so as to determine whether to end the fingerprint registration.
