Problems solved by technology

However, the inventor found that during the user input process, when the input is entered several times later, due to the high overlap rate between the pressed position and the previous few pressed positions, the user input recognition rate is low, causing the user to often need to replace it many times. Re-pressing the position not only reduces the user experience, but also lowers the entry efficiency

Embodiment Construction

[0054] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0055] The fingerprint entry method and device according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0056] In the prior art, when the fingerprint is entered, the number of times the user needs to enter is about 8 to 20 times. However, the inventor found that during the user input process, when the input is entered several times later, due to the high overlap rate of the pressed position and the position of the previous few times, the recognition rate of the use...

Abstract

The invention provides a fingerprint input method and device, wherein, the method comprises the following steps: a plurality of fingerprint images are collected in the process of continuous movement of a finger relative to a fingerprint module; For each fingerprint image, the fingerprint template is matched with the fingerprint template in the template set. The fingerprint template is used to describe the local fingerprint of the finger. If the fingerprint image is matched with the fingerprint template, the relative position of the fingerprint image and the fingerprint template is obtained. Ifit is determined that the fingerprint image and the fingerprint template are not duplicated according to the relative position, the fingerprint image is input into the template set. As that finger moves continuously on the fingerprint module, Compared with the existing fingerprint inputting method, the fingerprint inputting method avoids frequent pressing and low efficiency of subsequent inputting, shortens the fingerprint inputting time and improves the inputting efficiency by continuously moving the finger to find a new fingerprint area.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint entry method and device. Background technique [0002] Since the sensing area of ​​the fingerprint identification chip is relatively small, and the area of ​​the finger is relatively large, in the prior art, when entering the fingerprint, the user needs to continuously press different parts of the finger on the fingerprint identification chip, and the fingerprint entry of the finger can only be completed after multiple entries. . [0003] In the prior art, when the fingerprint is entered, the number of times the user needs to enter is about 8 to 20 times. However, the inventor found that during the user input process, when the input is entered several times later, due to the high overlap rate of the pressed position and the position of the previous few times, the recognition rate of the user input is low, causing the user to often need to replace...
