Abstract

The invention discloses a CABC (content adaptive brightness control) based power consumption controlling method. The method comprises the following steps: if the condition that an application runs in a display interface is detected, whether the display interface is switched is detected, and brightness change values of the display interface before and after switching are calculated; if the condition that the application exits from the display interface, the average brightness change value is calculated according to the brightness change values; a CABC value is regulated according to the average brightness change value. The invention further provides a mobile terminal. The mobile terminal comprises a display detection unit for detecting whether the application runs in the display interface, a switching calculation unit for calculating the brightness change values of the display interface before and after switching, an exit calculation unit for calculating the average brightness change value according to the brightness change values and a regulation unit for regulating the CABC value according to the average brightness change value. Different CABC values can be regulated according to different applications, and the power consumption is reduced.

Description

technical field [0001] The present invention relates to the technical field of power consumption management and control of terminals, in particular to a power consumption management and control method based on content adaptive backlight control (CABC) and a mobile terminal. Background technique [0002] As people spend more and more time using mobile terminals on average, the endurance performance of mobile terminals has attracted more and more attention from users, and has become an important factor affecting user experience. Therefore, designing a power consumption control strategy becomes a solution to improve battery life of mobile terminals at the software level. [0003] The display screen has always been a big power consumer in mobile devices, and the backlight of the display screen is a battery killer. At present, content-based adaptive backlight control (CABC) is a relatively mature backlight power-saving technology for mobile terminals. The meaning of CABC is: Co...
