Abstract

The embodiment discloses a method, a device and a mobile terminal switching background gray scales to save electricity; the method comprises the following steps: detecting the residual electricity quantity value of the terminal if the backlight control function is open; reducing the screen background image gray scale when the detected residual electricity quantity value is lower than or equal to the electricity quantity threshold value, thus updating a screen display frame; adjusting the gray scale and the screen backlight brightness of the updated screen display frame according to the backlight control function. The method and device can improve the screen backlight brightness dropping adjusting space, thus reducing terminal power consumption.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a method, device and mobile terminal for saving power by switching background gray scales. 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 take into account the low power consumption requirements of the terminal and the image quality displayed on the screen is an urgent problem to be solved in the field of image processing. [0003] Backlight control functions such as the Content Adaptive Brightness Control (CABC) function are 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. ...
