Terminal screen backlight adjusting method and terminal

Abstract

The invention discloses a terminal screen backlight adjusting method and a terminal. The terminal screen backlight adjusting method is characterized in that iris information and pupil information of eyes of a current user can be acquired under current backlight intensity of the terminal, and the area proportion of the iris and the pupil can be calculated according to the iris information and the pupil information, and can be used as the real-time sample data; by comparing the real-time sample data with the preset target sample data, when the real-time sample data is different from the target sample data, the screen backlight can be adjusted according to the preset strategy. Based on the adjusting of the screen backlight by the photoreceptor, the terminal backlight intensity can be adjusted automatically according to the real-time iris information and the real-time pupil information of the eyes of the user, the user requirement can be satisfied, and therefore the eyes of the user can be protected, and the watching comfortableness by using the eyes can be improved, and at the same time, the electric quantity of the terminal can be saved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for adjusting the backlight of a terminal screen and a terminal. Background technique [0002] With the popularity of smart phones, the functions of mobile phones are also increasing. People use mobile phones to socialize, read, play games, and spend more and more time staring at the screen. [0003] Staring at the mobile phone screen for a long time will cause dry eyes and blurred vision, headache and eye fatigue, and even induce chronic inflammatory lesions of conjunctival tissue; by adjusting the brightness of the screen, it can not only effectively reduce the damage to the eyes caused by the screen, protect vision, but also Extend phone battery life. [0004] The automatic backlight adjustment of the mobile phone is to install a light sensor on the front of the display panel of the display terminal. When the external (mainly the front of the display terminal) li...

Problems solved by technology

[0005] However, the screen backlight intensity of the display terminal obtained through adjustment according to the illumination change is usually not the screen backlight intensity required by the user, and cannot meet the needs of each user.

Moreover, since the human eye directly faces the screen of the display terminal, the light seen by the human eye is the light from the back direction of the screen of the display terminal, and the light sensed by the photosensor is the light from the front direction of the screen of the display terminal. Contrary to the light direction sensed by the light sensor, the light change sensed by the light sensor is often not the light change seen by the human eye, so there is a large error with the actual screen backlight intensity requirements of the user's human eye, which cannot meet the user's screen.
