    摘要: 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.

    摘要: A method and an apparatus for determining existence of a foreign material on a surface of a fingerprint sensor, and a mobile terminal are provided. The method includes the following. A current capacitance value of the fingerprint sensor of the terminal is obtained. A first difference between the current capacitance value and a preset capacitance reference value is calculated. Determine that the foreign material is present on the surface of the fingerprint sensor when the first difference is within a preset foreign-material threshold range.
