Claim One:
1. A method for controlling unlocking, comprising: acquiring a number of feature points in a current feature point set of a finger of a user, the current feature point set being formed by scanning the finger by a mobile terminal according to a current sensing electrode set, the current sensing electrode set comprising sensing electrodes from the ([M/2]−k11) th row to the ([M/2]+k12) th row in a sensing electrode array with M rows and N columns, the sensing electrode array being arranged in a fingerprint identification module of the mobile terminal, and M, N, k11, and k12 being positive integers; adding X rows of sensing electrodes to the current sensing electrode set to update the current sensing electrode set, when the number of the feature points in the current feature point set is smaller than a first preset threshold; scanning the finger according to sensing electrodes in the current sensing electrode set updated to obtain fingerprint data; generating a fingerprint image based on the fingerprint data; extracting feature points from the fingerprint image and updating the current feature point set based on the feature points extracted, the X rows comprising X1 rows preceding and adjacent to the ([M/2]−k11) th row and X2 rows next to and adjacent to the ([M/2]+k12) th row, with X1, X2, and X being positive integers; and unlocking the mobile terminal when the number of the feature points in the current feature point set is greater than or equal to the first preset threshold and the current feature point set is matched with a pre-saved fingerprint template.
