Problems solved by technology

[0003] Fingerprint identification technology has also become a standard technology for electronic equipment. With the development of fingerprint identification technology, the optical fingerprint identification module is currently more popular. This optical fingerprint identification module can be well integrated under the screen. Based on this, dry The fingerprint image of the finger is very different at low temperature and normal temperature. In particular, if the fingerprint template image is entered at low temperature, fingerprint recognition is performed at normal temperature, or the fingerprint image is entered at normal temperature, and fingerprint recognition is performed at low temperature. less efficient

Abstract

The embodiment of the application discloses a fingerprint identification method and related products, which are applied to an electronic device. A plurality of fingerprint template libraries are stored in the electronic device in advance, each fingerprint template library comprises at least one fingerprint template image, and each fingerprint template library corresponds to a temperature range. The method includes: acquiring a first fingerprint image; when the first fingerprint image is successfully identified by a fingerprint, comparing the first fingerprint image with the plurality of fingerprint template libraries to obtain a plurality of comparison values; selecting a target comparison value from that plurality of comparison values, and storing the first fingerprint image in a target fingerprint template library corresponding to the target comparison value, and the target fingerprint template library is one fingerprint template library of the plurality of fingerprint template libraries. As that embodiment of the present application is adopted, the fingerprint identification efficiency can be improve for various ambient temperatures.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a fingerprint identification method and related products. Background technique [0002] With the popularization and application of electronic devices (such as mobile phones, tablet computers, etc.), electronic devices can support more and more applications, and their functions are becoming more and more powerful. Indispensable electronic supplies. [0003] Fingerprint recognition technology has also become a standard configuration technology for electronic equipment. With the development of fingerprint recognition technology, the optical fingerprint recognition module is currently more popular. This optical fingerprint recognition module can be well integrated under the screen. Based on this, dry The fingerprint image of the finger is very different at low temperature and normal temperature. In particular, if the fingerprint template image is recorded at l...
