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.

Description

technical field [0001] The invention belongs to the field of intelligent control, and in particular relates to a method, system and terminal for automatically continuing backlight based on face recognition. Background technique [0002] The prior art discloses a method for controlling the automatic backlight of a display screen, which includes the following steps: a. Turn on the camera at a predetermined time before the automatic backlight turns off the screen; b. Ashing the image acquired by the camera; c. d. Analyze whether there are predetermined facial organs or objects in the binarized image; e. If there are predetermined facial organs or objects, delay the automatic backlight screen, if not, return to step b until automatic It's time for the backlight to turn off the screen. [0003] The above-mentioned solution does not provide a flexible and delayed automatic backlight off-screen solution, which greatly reduces user experience. Contents of the invention [0004] ...
