Abstract

The invention embodiment discloses a fingerprint unlocking method and terminal; the method comprises the following steps: obtaining a fingerprint image; determining a plurality of target zones with the sharpness greater than a preset threshold value from the fingerprint image; matching each zone from the target zones with a preset fingerprint template; unlocking the terminal when the target zones are successfully matched with the preset fingerprint template. The fingerprint unlocking method and terminal can improve fingerprint unlocking efficiency.

Description

Technical field [0001] The invention relates to the field of electronic equipment, in particular to a fingerprint unlocking method and 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. Fingerprint recognition technology is the standard technology on the terminal. Fingerprint recognition technology can be widely used not only for terminal unlocking, wake-up, mobile payment, etc. With the popularity of fingerprint recognition technology, in order to achieve fast unlocking, the unlocking time of the terminal is also a direct concern of terminal manufacturers. [0003] In practical applications, users often find that when their fingers are too dry or too wet, they need to press the fingerprint recognition module multiple times to successfully unlock them, thus reducing the efficiency of fingerprint unlocking. Summary of the invention [00...
