Abstract

The embodiment of the invention discloses a fingerprint unlocking method. The fingerprint unlocking method comprises the steps that a fingerprint image is acquired; whether the fingerprint image is an image of a dry finger or an image of a wet finger; when the fingerprint image is the image of the dry finger or the image of the wet finger, downsampling is carried out on a preset fingerprint template; the fingerprint image is matched with the downsampled preset fingerprint template; when the fingerprint image is matched with the downsampled preset fingerprint template successfully, a terminal is unlocked. The embodiment of the invention further provides the terminal. By means of the fingerprint unlocking method and the terminal, when the fingerprint image is the image the dry finger or the image of the wet finger, the preset fingerprint template is downsampled, and therefore the fingerprint unlocking efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a fingerprint unlocking method and a terminal. Background technique [0002] With the rapid development of information technology, the use of terminals (such as mobile phones, tablet computers, etc.) is becoming more and more popular. As a standard technology on the terminal, fingerprint recognition technology can be widely used not only in unlocking, waking up, mobile payment, etc. of the terminal. While the fingerprint recognition technology is popular, in order to achieve fast unlocking, the unlocking time of the terminal is also a direct concern of the terminal manufacturer. [0003] In practical applications, users often find that when the fingers are too dry or too wet, it is necessary to press the fingerprint identification module several times to unlock successfully, thus reducing the efficiency of fingerprint unlocking. Contents of the invention [0004]...
