Abstract
A screen unlocking method of an electronic terminal is provided as follows. Recorded debug parameters used for selecting target fingerprint images in the most recent N instances are counted, to determine a most frequently used debug parameter, where N is a natural number. Current debug parameters are adjusted based on the most frequently used debug parameter, to debug fingerprint images currently acquired. A target fingerprint image is selected from the fingerprint images debugged. Whether the target fingerprint image satisfies an unlocking condition is identified and a screen of the electronic terminal is unlocked when the unlocking condition is satisfied. Accordingly, an image acquiring method and an electronic terminal are also provided.
