Abstract

The invention relates to the technical field of optical fingerprint identification, in particular to a fingerprint image acquisition method and device and electronic equipment. The fingerprint image acquisition method provided by the embodiment of the invention comprises the steps of controlling a fingerprint sensor to acquire a temporary fingerprint image when a touch operation for a fingerprint identification area on a display screen is detected; when a plurality of temporary fingerprint images are collected, judging whether the fingerprint identification area is in a highlight state or not according to the brightness change of the plurality of temporary fingerprint images; and if the fingerprint identification area is in the highlight state, controlling a fingerprint sensor to collect a fingerprint identification image. According to the fingerprint image acquisition method and device and the electronic equipment provided by the embodiment of the invention, the image quality of the fingerprint identification image can be improved.

Description

technical field

[0001] The present application relates to the technical field of optical fingerprint identification, in particular, to a fingerprint image collection method, device and electronic equipment. Background technique

[0002] For the fingerprint module under the screen, in the prior art, the acquisition control process of its fingerprint recognition image is: 1. Wait for the touch operation for the fingerprint recognition area on the display screen; 2. After detecting the touch operation for the fingerprint recognition area on the display screen After the touch operation, refresh the light spot to the display; 3. After waiting for a fixed delay, the default display is already in the highlighted state; 4. Collect fingerprint recognition images. However, in the actual implementation process, due to the complexity of the multi-tasking parallel operating system in the electronic device where the fingerprint module is located, and the abnormality of the display hardwar...
