Abstract

Embodiments of the present disclosure provide a method for capturing a fingerprint image, an apparatus for capturing a fingerprint image, and an electronic device, where the method includes: controlling a fingerprint sensor to capture at least one frame of image based on each candidate exposure time among N candidate exposure times respectively; determining N values of a feature parameter corresponding to the N candidate exposure times according to the at least one frame of image captured in each exposure time, where the feature parameter is used to indicate a degree of influence of a refresh period of a display screen on the fingerprint image captured by the fingerprint sensor; determining a candidate exposure time corresponding to a first value indicating a smallest degree of influence among the N values as a target exposure time; and controlling the fingerprint sensor to capture the fingerprint image based on the target exposure time.
