Abstract

The embodiment of the present invention discloses an optical fingerprint verification method and related products. The method includes: when the mobile terminal receives a fingerprint collection instruction, the mobile terminal controls the optical sensor to detect the current external ambient light intensity, and sends the current external ambient light intensity to to the AP; when the AP determines that the current ambient light intensity falls into the target external ambient light intensity interval, the mobile terminal obtains the target external ambient light intensity through the AP according to the corresponding relationship between the external ambient light intensity interval and the fingerprint template data set. The target fingerprint template data corresponding to the interval; the mobile terminal controls the internal light source of the optical fingerprint identification module to collect fingerprint data; the mobile terminal judges whether the fingerprint data matches the target fingerprint template data through the AP; if it matches, the mobile terminal determines that it has passed the fingerprint verification. The embodiments of the present invention can improve the success rate of optical fingerprint matching.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an optical fingerprint verification method and related products. Background technique [0002] With the application of mobile terminals such as smart phones more and more widely, people in modern life basically have a mobile phone in hand. Current mobile phones generally adopt fingerprint recognition technology, which can be used in various aspects such as unlocking of mobile terminals and mobile payment. [0003] Optical fingerprint recognition technology is widely used in fingerprint recognition modules of various mobile terminals due to its advantages of good stability and high recognition sensitivity. An optical fingerprint recognition module generally includes a light source and an optical fingerprint detection module. The imaging principle of optical fingerprint recognition is: the light source emits light, the light passes through the surface of the display scre...
