Optical fingerprint collection method and device and user terminal

Abstract

The invention provides an optical fingerprint collection method and device and a user terminal. The method includes: receiving a pressing signal in a fingerprint collection area; and switching systemUI (User Interface) outside a fingerprint range, which corresponds to the pressing signal, to dark-color UI to facilitate optical fingerprint collection on a fingerprint of the fingerprint range. According to the method provided by the invention, system UI of the fingerprint range is switched to high-light fingerprint collection UI in optical fingerprint collection, that is, the range of fingerprint pressing is set to a high-light state so as to realize collection of the optical fingerprint, the other areas still maintain the original UI and original light ray intensity, problems of glare andvisual fatigue due to that all the areas are in a high-light mode in fingerprint collection are avoided, a visual effect is good, and better user experience is provided.

Description

technical field [0001] The present invention relates to the technical field of fingerprint collection, and more specifically, to an optical fingerprint collection method, device and user terminal. Background technique [0002] Fingerprint identification refers to identification by comparing the detailed feature points of different fingerprints. Fingerprint recognition technology involves image processing, pattern recognition, computer vision, mathematical morphology, wavelet analysis and many other disciplines. Because everyone's fingerprints are different, even between the ten fingers of the same person, there are obvious differences in fingerprints, so fingerprints can be used for identification. [0003] At present, the mainstream fingerprint recognition technologies used in the market mainly include the following three types: capacitive pressing technology, optical fingerprint recognition technology and ultrasonic fingerprint recognition technology; among them, capaciti...

Problems solved by technology

[0003] At present, the mainstream fingerprint recognition technologies used in the market mainly include the following three types: capacitive pressing technology, optical fingerprint recognition technology and ultrasonic fingerprint recognition technology; among them, capacitive pressing technology is relatively mature, but if the fingerprint has other interference, the accuracy rate will be greatly reduced; Ultrasonic fingerprint recognition technology needs to open holes on the device, which reduces the waterproof performance of the device; while optical fingerprint recognition technology is more and more favored by more and more intelligent terminal R&D and production enterprises due to its fast response speed and accurate recognition rate

[0004] When the existing smart terminals using optical recognition perform fingerprint recognition, all areas of the smart terminal or the fingerprint collection area as a whole need to be set to a high-light mode, and the fingerprint features are collected and extracted through the high-light mode. The whole process of the collection is kept in a high-gloss state, so that when the user is collecting fingerprints, especially at night, high-light glare will cause glare, visual fatigue, and even cause instant blindness to a certain extent. The visual effect is not good and the user experience is poor.
