AI Technical Summary

Technical Problem

In existing technologies, under-display optical fingerprint recognition suffers from problems such as low fingerprint image signal-to-noise ratio due to reduced screen transmittance, resulting in insensitive unlocking or lack of support for optical fingerprint unlocking.

Method used

By highlighting the fingerprint area on the screen and delaying for a preset time, the fingerprint sensor module collects the fingerprint image formed by the reflected light, ensuring that the preset time is related to the time when the reflected light reaches the fingerprint sensor module, thus reducing the collection of noisy light.

Benefits of technology

It improves the fingerprint signal-to-noise ratio, enhances the effect of optical fingerprint processing, and expands the applicable scenarios of optical fingerprint, especially achieving accurate fingerprint recognition even when the screen transmittance is low.

Abstract

The invention relates to a fingerprint processing method and device, electronic equipment, a storage medium and a program product. The fingerprint processing method comprises the following steps: in response to an operation instruction that a fingerprint object acts on a fingerprint area of a screen in the electronic equipment, controlling the fingerprint area of the screen to perform highlight display; wherein the displayed light passes through the screen and is reflected by the fingerprint object to form reflected light; collecting the reflected light to obtain a fingerprint image; wherein a fingerprint acquisition module of the electronic equipment performs acquisition after the fingerprint object acts on the fingerprint area for a preset time, and the preset time is associated with the time when the reflected light reaches the fingerprint acquisition module; and based on the fingerprint image, executing a processing operation corresponding to the operation instruction. According to the embodiment of the invention, optical fingerprint processing can be better realized.
