Abstract

The invention applies to the technical field of mobile terminals, and provides a backlight adjustment method and device or a mobile terminal. The method comprises steps as follows: screen backlight values corresponding to different camera shooting parameters are preset; when the mobile terminal triggers backlight adjustment, a camera of the mobile terminal is started; a shooting parameter of the camera is obtained; backlight brightness of the mobile terminal is adjusted to a screen backlight value corresponding to the shooting parameter. According to the backlight adjustment method and device of the mobile terminal, the camera of the mobile terminal is used as an auxiliary light sensing device, so that the screen backlight value, needing to be adjusted, of the mobile terminal is calculated; the accuracy of backlight adjustment can be improved, interference caused by light-sensing errors is reduced, and the display effect of a screen of the mobile terminal is improved.

Description

technical field [0001] The invention belongs to the technical field of mobile terminals, and in particular relates to a method and device for adjusting a backlight of a mobile terminal. Background technique [0002] At present, automatic backlight adjustment has become one of the essential functions of smartphones. Under different ambient light intensities, this function will ensure that the screen is always at an appropriate brightness, so that users can always see the screen content clearly. Usually, the backlight adjustment of the mobile phone is realized based on the ambient light sensor installed inside the mobile phone. The different ambient light intensity values ​​measured by the ambient light sensor will directly correspond to a light source brightness value, and the mobile phone screen is adjusted according to the light source brightness value. The brightness of the light source, so as to realize automatic backlight adjustment. [0003] However, affected by variou...
