OPTICAL FINGERPRINT RECOGNITION MODULE, RECOGNITION METHOD THEREOF, AND ELECTRONIC APPARATUS

An optical fingerprint recognition module, a recognition method thereof, and an electronic apparatus: inputting a first image of a fingerprint into a fingerprint recognition model, and using the fingerprint recognition model to implement real or fake determination of the fingerprint; as the fingerprint recognition model comprises a convolutional neural network model that uses real and fake fingerprint training sample sets for deep learning training, real human fingerprints can be distinguished from 2D fingerprint images and 3D fingerprint models, effectively improving the anti-counterfeit performance and security performance of the optical fingerprint recognition module; the first image of the fingerprint is acquired on the basis of the image information of a preset number of pixel units randomly selected from different areas, increasing the flexibility of selecting pixel unit image information, reducing the influence on the first image of the image information of pixel units in certain areas such as transiti
