Abstract

The invention provides an under-screen fingerprint collection method and device, electronic equipment and a storage medium. The under-screen fingerprint collection method comprises the steps: collecting a first fingerprint image of a user under the irradiation of a light source; determining the target exposure time of the image sensor according to the pixel value of the first fingerprint image; controlling the exposure time of the image sensor to be the target exposure time; and under the target exposure time, collecting a second fingerprint image of the user. According to the embodiment of the invention, the exposure time of the image sensor is adjusted according to the current environment, and the fingerprint image of the user is continuously acquired at the target exposure time, so thatthe quality of the fingerprint image can be effectively improved, and the influence of ambient light on fingerprint acquisition under a screen is avoided.

Description

technical field [0001] The present application relates to the technical field of fingerprint collection, in particular to an off-screen fingerprint collection method, device, electronic equipment and storage medium. Background technique [0002] Fingerprint identification technology is an identification method for verifying identity through fingerprint comparison, and it is also the most widely used biometric identification technology today. With the development of terminal equipment and the development of fingerprint recognition technology, the demand for fingerprint recognition technology in the fields of personal computers, smart phones, and door locks is also expanding. [0003] In the prior art, in the process of acquiring the fingerprint image of the user, infrared light is usually used as the light source of the fingerprint device under the liquid crystal display (Liquid Crystal Display, LCD). The screen and special optical lens are received by the sensor under the s...
