METHOD AND APPARATUS FOR SETTING SCREEN BRIGHTNESS Russian patent published in 2018 - IPC G09G5/10 H05B37/02 

FIELD: mobile devices.

SUBSTANCE: invention relates to the field of brightness control of a mobile device screen, namely, brightness control based on measurement of ambient light. To this end, light sensor receives the first brightness of ambient light in the environment where the terminal is located, and detects whether the light sensor is directed to the opposite side from the light source in the environment. Next, the first backlight brightness level is calculated according to the first brightness of ambient lighting, if the light sensor is directed to the opposite side from the light source, wherein the said first backlight brightness level is higher than the second backlight brightness level, which is calculated according to the first brightness of ambient lighting when the light sensor is directed toward the light source. And then the terminal backlight brightness is set to the first level of backlight brightness. Thus, the problem of calculating an inaccurate level of backlight brightness is solved when the light sensor is directed in the opposite direction from the light source, since the measured brightness of ambient lighting is lower when the light sensor is directed to the opposite side from the light source.

EFFECT: technical result is an increase in the accuracy of the backlight brightness level due to the determination of the relative position of the light sensor and the light source.
