Abstract

The invention provides an automatic backlighting continuation method, system and terminal based on face recognition. The automatic continuation backlighting method includes the following steps that when the terminal detects that the distance between a face and a terminal screen is smaller than the preset value, the terminal screen backlight is lighted up, and the backlight closing cycle is set; when the backlight closing cycle is reached, the terminal compares the obtained face image information and the stored face feature information, and if matching is successful, the next backlight closing cycle is entered; the terminal conducts statistics on the face detection times and the face matching success times in a preset time frame and obtains the face matching success rate according to the obtained face detection times and the face matching success times and a preset strategy; the terminal obtains the adjusted backlight closing cycle according to the obtained face matching success rate, a face matching success rate range and a backlight closing cycle adjustment strategy table. By means of the automatic backlighting continuation method, system and terminal based on face recognition, a flexible automatic backlight screen off delay scheme is provided, and the user experience is greatly improved.
