Fingerprint identification method and related product

Abstract

The embodiment of the invention discloses a fingerprint identification method and a related product, which are applied to electronic equipment, the electronic equipment comprises an optical fingerprint identification module, and the method comprises the following steps: when a user presses the optical fingerprint identification module, determining a target pressing area of the user pressing the optical fingerprint identification module; when the target pressing area is smaller than a preset area threshold value, controlling the optical fingerprint recognition module to perform a first fingerprint collection mode, and performing fingerprint collection based on a first area of a first size to obtain a first fingerprint image; and when the target pressing area is greater than the preset areathreshold value, controlling the optical fingerprint identification module to perform a second fingerprint acquisition mode, and performing fingerprint acquisition based on a second area of a second size to obtain a second fingerprint image, the first size being smaller than the second size. According to the embodiment of the invention, the corresponding fingerprint acquisition mode can be selected according to the size of the finger, and the fingerprint input efficiency is improved.

[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. The optical fingerprint identification module can be well integrated under the screen. However, based on optical The electronic device of the fingerprint identification module may appear during the fingerprint collection process, and the fingerprint of the small finger (for example, a child's finger) may not be recorded, so it brings a bad user experience
