Problems solved by technology

In the full-screen fingerprint entry, if the finger is lifted immediately after the collection action is completed, the actual fingerprint image may be blurred, resulting in blurred lines of the fingerprint image that has been successfully entered, and there will be a relatively high probability of subsequent fingerprint recognition. Abnormal matching, resulting in low success rate of fingerprint recognition

Abstract

The embodiment of the present application discloses a fingerprint entry method, device, electronic equipment, and storage medium. The method includes: detecting the first fingerprint pressing operation in the fingerprint collection area of ​​the touch screen; A first fingerprint image generated during the fingerprint pressing operation; if the image quality of the first fingerprint image is less than the first preset threshold, re-collect the first fingerprint image generated during the first fingerprint pressing operation through the under-screen fingerprint sensor A second fingerprint image; if the image quality of the second fingerprint image is greater than or equal to the first preset threshold, record the second fingerprint image. It can improve the fingerprint recognition success rate of the fingerprint sensor under the screen.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a fingerprint entry method, device, electronic equipment and storage medium. Background technique [0002] With the popularization and application of a large number of electronic devices (such as mobile phones, tablet computers, etc.), the functions of electronic devices are becoming more and more powerful. Current electronic equipment generally adopts a full screen, and the fingerprint recognition under the full screen generally adopts the fingerprint recognition under the screen. In the full-screen fingerprint entry, if the finger is lifted immediately after the collection action is completed, the actual fingerprint image may be blurred, resulting in blurred lines of the fingerprint image that has been successfully entered, and there will be a relatively high probability of subsequent fingerprint recognition. The matching is abnormal, resulting in a low success rat...
