Problems solved by technology

[0002] In daily life, many people have the habit of playing with smart devices such as mobile phones before going to bed. If they turn on the lights at this time, it will waste energy and affect other people.
If you don’t turn on the light and use the mobile phone in an environment with extremely low brightness (such as 0.001lux at night), most people’s solution is to reduce the brightness of the mobile phone, but the current brightness is limited by the LCD backlight circuit, structure, control method and cost. , it is difficult to achieve extremely low brightness, which will cause great damage to the eyes when used in a very dark environment (such as 0.001lux at night)

Abstract

The invention relates to a display brightness adjustment method and device. The display brightness adjustment method comprises the steps of obtaining original gray-scale values of pixel points on a display interface, conducting gray-scale transformation on the pixel points to obtain transformed gray-scale values of the pixel points, and adjusting gray scale of the interface according to the transformed gray-scale values of the pixel points.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to a method and device for adjusting display brightness. Background technique [0002] In daily life, many people have the habit of playing with smart devices such as mobile phones before going to bed. If they turn on the lights at this time, it will waste energy and affect other people. If you don’t turn on the light and use the mobile phone in an environment with extremely low brightness (such as 0.001lux at night), most people’s solution is to reduce the brightness of the mobile phone, but the current brightness is limited by the LCD backlight circuit, structure, control method and cost. , It is difficult to achieve extremely low brightness, which will cause great damage to the eyes when used in a very dark environment (such as 0.001lux at night). Contents of the invention [0003] The disclosure provides a display brightness adjustment method and device. [0004]...
