Abstract
A method and a mobile terminal for controlling unlocking include the following. The number of feature points in a current feature point set of a finger is acquired. X rows of sensing electrodes are added to the current sensing electrode set to update the current sensing electrode set. The finger is scanned according to sensing electrodes in the current sensing electrode set updated to obtain fingerprint data. A fingerprint image is generated based on the fingerprint data. Feature points are extracted from the fingerprint image and the current feature point set is updated based on the feature points extracted. The terminal is unlocked 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.
