Abstract

The invention relates to a backlight brightness adjusting method and a device thereof, which belong to the technical field of electronics. The method comprises the following steps: acquiring a brightness curve, wherein the brightness curve is used for representing a corresponding relationship between an ambient light brightness value and a backlight brightness value; obtaining an ambient light brightness value of the current environment; acquiring an image brightness value of the current frame image; determining a target backlight brightness value according to the brightness curve, the ambientlight brightness value and the image brightness value; and adjusting the backlight brightness of a screen according to the target backlight brightness value. According to the invention, the backlightbrightness of the screen is adjusted by combining the ambient light brightness value and the image brightness value of the current frame image, so that the adjusted backlight brightness of the screencan better meet the watching requirements of human eyes, a user feels more comfortable when watching the screen, the visual fatigue is relieved, and the watching experience of the user is improved.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a method and device for adjusting brightness of a backlight. Background technique [0002] At present, terminals such as smartphones, tablet computers, and e-book readers have become indispensable tools for users, and play an important role in daily life, work, and study. With the prevalence of audio-visual entertainment electronic products, e-books, etc., users can use terminals during rest and travel. However, when the user watches the screen of the terminal, the brightness of the backlight that is too bright or too dark will make the user feel visual fatigue. In order to alleviate the user's visual fatigue, the brightness of the backlight of the screen can be adjusted. [0003] At present, related technologies mainly adjust the brightness of the backlight of the screen in combination with the ambient light brightness value of the environment where the terminal i...
