Embodiment 1

[0074] figure 1 It shows the implementation process of the fingerprint touch method provided by Embodiment 1 of the present invention, and the details are as follows:

[0075] In step S101, a first fingerprint image and a second fingerprint image are acquired.

[0076] In the embodiment of the present invention, a fingerprint recognition chip is built in the fingerprint touch device. When the fingerprint recognition chip detects that a finger touches the fingerprint device, it can collect fingerprint images. The frequency of collection is determined by the scanning frequency of the device. The first fingerprint image and the second fingerprint image can be two adjacent images collected, or images selected according to certain requirements, for example, every two adjacent odd-numbered scans from the first The obtained images are the first fingerprint image and the second fingerprint image and so on, and different rules can be adopted according to different needs.

Abstract

The invention belongs to the technical field of touch control and provides a method and device for fingerprint touch control and fingerprint equipment. The method includes the steps that a first fingerprint image and a second fingerprint image are acquired; the center coordinates of the first fingerprint image and the center coordinates of the second fingerprint image are calculated; corresponding touch control operation is executed according to the difference value between the center coordinates of the first fingerprint image and the center coordinates of the second fingerprint image. Only the center coordinates of the two acquired fingerprint images need to be calculated, the corresponding touch control operation is executed according to the difference value between the center coordinates of the two fingerprint images, the calculated quantity is only on the level N, the method is simple, consumed time is short, and the good operation real-time effect is achieved.

Description

technical field [0001] The invention belongs to the field of touch technology, and in particular relates to a fingerprint touch method, device and fingerprint equipment. Background technique [0002] With the continuous development of fingerprint devices and fingerprint device software technology, fingerprint devices are more and more widely used in daily work and life. [0003] When the finger operates the fingerprint device, the display page on the fingerprint device can perform sliding operations such as page turning, moving up, and moving down according to the size and direction of the finger's movement. [0004] The existing fingerprint touch method first records N pieces of fingerprint information of the user's finger from touching the fingerprint device until it moves to a certain distance and direction in the whole process of the touch action, and then collects N pieces of fingerprint information of the user's finger. The fingerprint feature points of the fingerprin...
