Abstract
Disclosed are a method and a related product for recognizing a live face. The method is applied to a terminal device including a front light emitting source, a front camera and an Application Processor (AP). The method includes the following actions. Upon reception of a face image collection instruction, the camera collects a first face image of a face when the source is in a first state. The camera collects a second face image of the face when the source is in a second state. The AP determines whether a difference between an eyeball area proportion in the first face image and an eyeball area proportion in the second face image is larger than a preset threshold; and if so, the AP determines that the collected face images are images of a live face.
