Abstract:
A method for fingerprint unlocking is provided. Whether fingerprint ridges of fingerprint images obtained are discontinuous or fuzzy is determined, in response to a fingerprint recognition module being detected to be pressed. If YES, Multiple fingerprint images are acquired, by acquiring fingerprints more than once with any first adjustment level selected from an ADC offset including M first adjustment levels and any second adjustment level selected from an ADC gain including N second adjustment levels. Multiple image quality evaluation values are obtained, by performing an image quality evaluation on each of the plurality of fingerprint images according to one or more image quality evaluation indexes, and a fingerprint image corresponding to a maximum image quality evaluation value is selected as a target fingerprint image. A terminal is unlocked when the target fingerprint image matches a preset fingerprint image successfully. A terminal is also provided.

Claim (Index 3):
The method of  claim 2 , wherein determining the target fingerprint image with the best image quality from the plurality of fingerprint images by using the at least one image quality evaluation index configured to evaluate fingerprint images comprises:\n calculating an image quality evaluation value of each fingerprint image of the plurality of fingerprint images with a formula S = \u2211 i = 1 K \ue89e \u2202 i \ue89e P i ; and\n using a fingerprint image corresponding to a maximum image quality evaluation value as the target fingerprint image; \n S representing the image quality evaluation value, K representing the number of the image quality evaluation indexes, P i  representing an image quality evaluation value corresponding to the i th  image quality evaluation index, \u2202 i  representing a weight of the i th  image quality evaluation index, and \n \u2211 i = 1 K \ue89e \u2202 i = 1.
