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 productio

Embodiment 1

[0059] refer to figure 2 , the first embodiment of the present invention provides an optical fingerprint collection method, including:

[0060] Step S10, receiving a pressing signal in the fingerprint collection area;

[0061] The optical fingerprint collection method described in the present invention can be applied to fingerprint collection equipment using optical fingerprint recognition technology, for example, it can include but not limited to the interactive interface of mobile phones, tablet computers, attendance machines, gate authentication devices, etc., in this In the embodiment, it can be applied to a smart phone or a tablet computer with a touch screen and using optical fingerprint identification technology.

[0062] As mentioned above, the fingerprint collection area is the specified area that appears on the interactive interface, such as the screen, under the command of fingerprint collection. For example, when performing fingerprint authentication, it can be t...

Embodiment 2

[0071] refer to image 3 , the second embodiment of the present invention provides an optical fingerprint collection method, based on the above figure 2 In the first embodiment shown, before the step S20 of "switching the system UI outside the fingerprint range corresponding to the pressing signal to a dark UI, so as to perform optical fingerprint collection on the fingerprints in the fingerprint range", there is also include:

[0072] Step S30, acquiring the pressure-sensitive touch pressure value corresponding to the pressing signal;

[0073] It should be understood that the pressure-sensitive touch technology may include but not limited to ClearForce pressure-sensitive touch solution, Force Touch technology, 3D Touch touch technology and other technologies.

[0074] As mentioned above, it needs to be understood that pressure-sensitive touch (pressure touch technology) is equipped with force sensors at the four corners of the screen, which can sense the pressure of pressi...

Embodiment 3

[0081] refer to Figure 4 , the third embodiment of the present invention provides an optical fingerprint collection method, based on the above image 3 In the second embodiment shown, after the step S20 of "switching the system UI outside the fingerprint range corresponding to the pressing signal to a dark UI, so as to perform optical fingerprint collection on the fingerprints in the fingerprint range", further include:

[0082] Step S60, judging whether the pressure-sensitive touch pressure value reaches a second preset pressure range;

[0083] As mentioned above, the second preset pressure range is the preset condition for starting fingerprint feature acquisition and fingerprint recognition, that is, when the pressure-sensitive touch pressure value reaches the second preset pressure range, the user’s fingerprint range starts to be detected. Fingerprints are collected.

[0084] In this embodiment, the pressure value in the second preset pressure range is greater than the ...

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...
