Abstract

The invention relates to the field of the computer technology, and discloses a fingerprint unlocking method under a standby state. The fingerprint unlocking method comprises the following steps: after a fingerprint identification module senses a trigger signal, collecting a first image, and sending the first image to a thread with low power consumption; judging whether the first image is a fingerprint image or not by the thread with the low power consumption; if the first image is the fingerprint image, generating a system awakening signal by the thread with the low power consumption to cause a processing unit to enter a normal working state; collecting at least one image again by the fingerprint identification module, and sending the image which is collected again to the processing unit; and carrying out fingerprint unlocking by the processing unit according to the image received by the fingerprint identification module, wherein the received image at least comprises the image which is collected again. Through the above steps, when the electronic equipment collects the fingerprint image, the processing unit is firstly awakened to cause the processing unit to carry out fingerprint matching unlocking so as to greatly improve the response speed of the fingerprint unlocking and quickly awaken the system under system dormancy.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a fingerprint unlocking method in a standby state. Background technique [0002] With the advancement of electronic technology, fingerprint recognition has gradually become a standard configuration of electronic devices represented by smart phones. Naturally, people have put forward higher requirements on the speed of fingerprint recognition. [0003] Under the prior art, when the electronic device detects that the user touches the fingerprint identification module, it will first identify whether the collected fingerprint matches the preset fingerprint, and only when the collected fingerprint matches the preset fingerprint, the system will be woken up and unlocked successfully. Since the current fingerprint unlocking is generally carried out in the standby state, the entire unlocking process from the user touching the fingerprint recognition module to the successful unlocking ...
