Abstract
A fingerprint enrolling method, a fingerprint enrolling apparatus, and a terminal device are provided. The method includes the following operations. Whether an image-quality fluctuation amplitude of fingerprint images of a user exceeds a preset image-quality fluctuation threshold or image-quality fluctuation threshold range is determined according to image quality of a current fingerprint image of the user currently acquired and image quality of a historical fingerprint image of the user previously acquired. The current fingerprint image is enrolled into a fingerprint database based on a determination that the image-quality fluctuation amplitude does not exceed the image-quality fluctuation threshold or the image-quality fluctuation threshold range.
