Embodiment 1

[0026] refer to figure 1 , shows a flow chart of the steps of a fingerprint identification method in Embodiment 1 of the present invention, including the following steps:

[0027] Step 101: Collect fingerprint images in the fingerprint identification area.

[0028] Specifically, when the fingerprint authentication interface is turned on, when the terminal detects an operation of pressing a finger on the fingerprint identification area, the fingerprint image is collected. The fingerprint authentication interface may be an unlocking interface of the terminal, or may be an unlocking interface of an application program.

[0029] Step 102: Determine whether there are preset types of pixels in the fingerprint image.

[0030] Wherein, the preset type of pixels can be the pixels corresponding to the stains on the finger pressed on the fingerprint identification area, or the pixels corresponding to the stains on the fingerprint identification area, and its specific form can be bliste...

Embodiment 2

[0038] refer to figure 2 , shows a flow chart of the steps of a fingerprint identification method in Embodiment 2 of the present invention, including the following steps:

[0039] Step 201: Detect the pressing area of ​​the finger, and determine whether the overlapping area between the pressing area of ​​the finger and the fingerprint recognition area is smaller than a first preset value; if yes, execute step 202; if not, execute step 203.

[0040] The fingerprint recognition area is set on the terminal screen. When the user presses the screen with a finger, the user may not be able to accurately press the fingerprint recognition area because the fingerprint recognition area is hidden and displayed. If the finger presses and deviates greatly from the fingerprint recognition area, the fingerprint image will not be successfully collected or only the fingerprint image containing the fingerprint of the finger will be collected, and the above two fingerprint images will seriously ...

Embodiment 3

[0063] refer to image 3 , shows a structural block diagram of a terminal according to Embodiment 3 of the present invention, including:

[0064] A collection module 301, configured to collect fingerprint images in the fingerprint identification area;

[0065] A first judging module 302, configured to judge whether there are pixels of a preset type in the fingerprint image;

[0066] The first prompt information output module 303 is configured to output first prompt information if the judgment result of the first judgment module is that there is a preset type of pixel.

[0067] The terminal provided by the embodiment of the present invention does not blindly perform fingerprint image matching after the fingerprint image is collected, but judges whether there are preset types of pixels in the fingerprint image. Through this judgment, the quality of the fingerprint image can be improved, and then fingerprint recognition can be improved. rate to improve user experience.

Abstract

The embodiment of the invention provides a fingerprint identification method and a terminal. The method comprises steps: a fingerprint image is acquired in a fingerprint identification area; whether a preset type of pixel points exists in the fingerprint image is judged; and if the preset type of pixel points exists in the fingerprint image, first prompting information is outputted. The embodiment of the invention can improve the fingerprint image quality, the fingerprint identification rate is further enhanced, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a fingerprint identification method and a terminal. Background technique [0002] With the development of science and technology, the collection, storage and sharing of information has become simple, fast and efficient, bringing great convenience to people's life and work. As an indispensable tool in people's daily life, smart terminals carry a lot of private information and security data. Therefore, how to efficiently protect important information from unauthorized access and ensure convenient and fast access for users has become particularly important. [0003] In order to solve the above problems, designers have designed fingerprint recognition technology based on the characteristics of fingerprint stability, security, uniqueness, and no need for memory, and have widely applied fingerprint recognition technology to smart terminals. Locking, so as to achieve the purpose...
