Fingerprint acquisition method and related product

Abstract

The embodiment of the invention discloses a fingerprint acquisition method and a related product. Application to electronic equipment, The electronic device comprises an optical fingerprint identification module. The method comprises the following steps of: obtaining a target object; when the environment temperature is lower than the preset temperature, if a user presses the optical fingerprint recognition module, the target fingerprint collection time length and the target fingerprint scanning frequency corresponding to the environment temperature are determined, the target fingerprint collection time length is larger than the fixed fingerprint collection time length, and within the target fingerprint collection time length, the optical fingerprint recognition module can complete multipletimes of fingerprint scanning; Controlling the optical fingerprint identification module to perform fingerprint acquisition according to the target fingerprint acquisition duration and the target fingerprint scanning frequency to obtain a plurality of fingerprint images; And selecting a target fingerprint image with the best image quality from the plurality of fingerprint images, wherein the target fingerprint image is used for subsequent fingerprint identification. According to the embodiment of the invention, the fingerprint image acquisition quality can be 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. Its main working principle Yes: Use the display itself to emit light. When the finger is placed on the screen, the self-luminescence will be reflected when it reaches the finger. The optical fingerprint recognition module receives the reflected light signal. Due to the uneven texture of the fingerprint, the light absorption range is different, thus obtaining Fingerprint images with different light and dark, however, under low temperature conditions, the user's fingers will appear dry fingers, due to shallow and dry lines, resulting in unclear fingerprint images collected, thus reducing the quality of fingerprint image collection
