Abstract

The invention provides a light supplementing method and device for face recognition and a computer readable storage medium, and the method comprises the steps: obtaining a light sensing value of a current environment when a first face recognition instruction is detected, and judging whether the light sensing value of the current environment is smaller than a preset brightness threshold value or not; If the brightness value is smaller than the preset brightness threshold value, displaying a light supplementing interface, obtaining the initial brightness value of the light supplementing interface, and determining the light supplementing level corresponding to the light sensing value of the current environment according to the corresponding relation between the preset environment light sensing value and the light supplementing level; And determining a primary adjustment parameter value of the light supplementing interface according to the light supplementing level and the initial brightness value, and gradually increasing the light supplementing interface to a level light supplementing brightness threshold value corresponding to the light supplementing level based on the primary adjustment parameter value. Through the mode, the face image acquisition quality and the face recognition efficiency are improved, the user experience is improved, and the technical problem that the facerecognition efficiency is low in an existing dark environment is solved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a face recognition supplementary light method, device and computer-readable storage medium. Background technique [0002] With the rapid development of science and technology, mobile terminals (mobile phones, tablet computers, etc.) are also rapidly popularized. Mobile terminals can support more and more applications and have more and more powerful functions. They have increasingly become indispensable electronic products in people's daily life. Among them, the face recognition function for unlocking verification is also gradually popularized and has become an essential function of mobile terminals. Due to large changes in environmental factors, it is difficult to guarantee the success rate of face recognition. For example, in a dark environment with insufficient light, it is difficult for the terminal to capture a clear face of the user, resulting in low face re...
