FINGERPRINT RECOGNITION METHOD, METHOD AND DEVICE FOR UPDATING FINGERPRINT TEMPLATE, AND MOBILE TERMINAL

摘要

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 between the fingerprint image and the ith fingerprint template of the fingerprint template set is greater than a second preset threshold, where the second preset threshold is greater than the first 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. Based on the method of recognizing fingerprints in an embodiment, the fingerprint templates of the fingerprint template set are no longer fixed. In a subsequent match procedure, the fingerprint images input by users continuously improve and supplement the fingerprint templates of the fingerprint template set.
