Abstract
A method for controlling unlocking is provided. The method includes the following operations. M first fingerprint images are received when a touch operation of a finger of a user on a fingerprint recognition module of a terminal device is detected. N second fingerprint images are received based on N sets of capacity auto control (CAC) parameters when the finger of the user is in a steady state. A first target fingerprint image is determined and a matching process on the first target fingerprint image is performed. The terminal device is unlocked when the first target fingerprint image is matched.
