Abstract
A method for controlling unlocking is provided. The method includes the following operations. Determine whether a finger of a user is in a steady state when a touch operation of the finger on a fingerprint recognition sensor of a terminal is detected. A first fingerprint image according to capacity auto control (CAC) parameters corresponding to a wet finger is received when the finger of the user is in the steady state. N second fingerprint images corresponding to N sets of CAC parameters are received during the receiving of the first fingerprint image. A target fingerprint image is determined and a fingerprint comparison is performed on the target fingerprint image. Unlock the terminal when detecting that the result of the fingerprint comparison is a match.
