A fingerprint unlocking method may include receiving a first fingerprint image. The number of target feature points of the first fingerprint image is determined. A target adjustment parameter corresponding to the number of target feature points is acquired according to a preset mapping relation between the number of feature points and adjustment parameters. A second fingerprint image is received according to the target adjustment parameter. A terminal is unlocked when the second fingerprint image matches with a preset fingerprint template. A terminal is also provided.

A fingerprint recognition method, a method and device for updating a fingerprint template, and a mobile terminal. The method comprises: acquiring a fingerprint image inputted by a user (S11); comparing the fingerprint image with N fingerprint templates in a prestored fingerprint template set (S12); if the degree of match between the fingerprint image and an i-th fingerprint template in the prestored fingerprint template set is greater than a first preset threshold, then controlling a mobile terminal to execute a corresponding target operation (S13); further determining whether or not the degree of match between the fingerprint image and the i-th fingerprint template in the prestored fingerprint template set is greather than a second preset threshold (S14), where the second preset threshold is greater than the first preset threshold; and if yes, then generating, on the basis of the fingerprint image, a new fingerprint template and adding same to the fingerprint template set (S15). The fingerprint recognition method, per which fingerprint templates are no longer fixed, allows, over subsequent uses by the user, continuous improvement and supplementation of the fingerprint templates in a fingerprint template set on the basis of fingerprint images used by the user.

Fingerprint recognition method, method and device for updating fingerprint template, and mobile terminal

A method of recognizing fingerprints, updating fingerprint templates, an apparatus and a mobile terminal are provided. The method includes acquiring a fingerprint image input by a user. The fingerprint image is compared with fingerprint templates pre-stored in a fingerprint template set, where the fingerprint template set comprises N-numbered fingerprint templates and N is a positive integer. A mobile terminal performs a target operation when a match value between the fingerprint image and an ith fingerprint template of the fingerprint template set is greater than a first preset threshold. The method determines whether the match value set is greater than a second preset threshold. The method generates a new fingerprint template based on the fingerprint image and adds the new fingerprint template to the fingerprint template set when the match value between the fingerprint image and the ith fingerprint template is greater than the second preset threshold.
