Abstract
A method for fingerprint recognition may include: acquiring a current charging state of the mobile terminal; updating setting of a fingerprint recognition threshold value according to the current charging state of the mobile terminal; acquiring a fingerprint image, and extracting feature information of the fingerprint image; and conducting a fingerprint recognition according to the extracted feature information and the fingerprint recognition threshold value. In embodiments of the present disclosure, the current charging state of the mobile terminal is acquired and setting of the fingerprint recognition threshold value is thus updated according to the current charging state of the mobile terminal, such that the mobile terminal can acquire the same fingerprint recognition rate regardless of different charging states.
