Abstract

The embodiment of the invention discloses a screen backlight adjustment method, device and mobile terminal. The method includes: if the backlight control function is on, determining whether the current application program is an image processing application program; if the current application program is an image processing application program, controlling the backlight control function to be off; turning the screen backlight Brightness minus the brightness reference value. The embodiment of the present invention can ensure the image quality of the image processing application program, reduce the power consumption of the terminal, and prevent the backlight from flickering.

Description

Technical field [0001] The invention relates to the field of electronic equipment, in particular to a screen backlight adjustment method, device and mobile terminal. Background technique [0002] With the rapid development of mobile communication technology and computer technology, mobile terminals such as smart phones and tablet computers have become indispensable communication tools in people's lives. How to balance the low power consumption requirements of the terminal and the image quality displayed on the screen is an urgent problem in the image processing field. [0003] Backlight control such as Content Adaptive Brightness Control (CABC) technology is used to adjust the relationship between the grayscale value of the image and the brightness of the screen backlight according to the image content displayed on the terminal screen, which can effectively reduce the brightness of the screen backlight at the same time To maintain the display quality of the image. However, the cu...
