Abstract
The present invention relates to a fingerprint enrollment method and an electronic device for performing the fingerprint enrollment method. A fingerprint sensor of the electronic device senses the fingerprint to generate the fingerprint images. The processor of the electronic device determines if M qualified fingerprint images are acquired or the number of times the finger touches the fingerprint sensor reaches N. When any of the above conditions is satisfied, the operation of sensing fingerprint is stopped. After that, the processor uses the fingerprint images to generate fingerprint enrollment information to complete the fingerprint enrollment process. Based on the disclosure of the present invention, the user can complete the fingerprint enrollment process regardless of whether the user uses spiral enrollment or pressing enrollment.
