Abstract

Embodiments of the invention provide a fingerprint unlocking method. The fingerprint unlocking method comprises the following steps: when a fingerprint recognition module is pressed, acquiring fingerprint by adjusting the adjustment parameters of a fingerprint acquisition chip in the fingerprint recognition module so as to obtain a plurality of fingerprint images; determining a target fingerprint image with optimal image quality in the plurality of fingerprint images; and unlocking a terminal when the target fingerprint image matches with a preset fingerprint image. The embodiments of the invention also provide the terminal. According to the embodiments of the invention, the target fingerprint image with optimal image quality can be obtained by adjusting the adjustment parameters, and the terminal is unlocked when the target fingerprint image matches with the preset fingerprint image, so the success rate of matching between the target fingerprint image and the preset fingerprint image can be improved; and thus, fingerprint unlocking efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of terminal 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] E...
