Abstract

Embodiments of the present invention provide a camera module and a mobile terminal with a fingerprint recognition function, and relate to the technical field of mobile terminals. In the embodiment of the present invention, the light-emitting unit is arranged above the circuit board, and the aperture is arranged above the light-emitting surface of the light-emitting unit to make the light emitted by the light-emitting unit uniform, and the image sensor is arranged above the circuit board. for collecting the fingerprint image of the user's finger. The user's finger pressing on the lens assembly is provided with light through the light-emitting unit and the aperture, so that the image sensor can collect the fingerprint image of the user's finger, and compare and analyze the collected fingerprint image with the pre-stored fingerprint image to realize fingerprint recognition. The module expands from the single-function camera function to the biometric function.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of mobile terminals, in particular to a camera module and a mobile terminal with a fingerprint recognition function. Background technique [0002] With the development of mobile terminal technology, the camera module has become a basic configuration of mobile terminals, such as mobile phones, tablet computers, smart wearable devices, etc. More and more users choose to use the camera module of mobile terminals to take pictures. It brings great convenience and fun to people's life and work. [0003] However, the current camera module in the mobile terminal is only responsible for the functions of taking photos and shooting videos. With the development of the camera module, its imaging quality and image processing effect are getting better and better. The camera module has a high pixel ratio In the case of high-resolution, high-definition shooting capabilities, the functions of taking pho...
