Abstract

The invention discloses a method for controlling power consumption based on CABC, comprising the steps of: if it is detected that an application program is running on a display interface; then detecting whether the display interface is switched, and calculating the brightness change value of the display interface before and after the switch; If it is detected that the application program exits the display interface; then calculate the average brightness change value according to the brightness change value; adjust the CABC value according to the average brightness change value. The present invention also provides a mobile terminal, including: a display detection unit, used to detect whether there is an application program running on the display interface; a switching calculation unit, used to calculate the brightness change value of the display interface before and after switching; exit the calculation The unit is used to calculate the average brightness change according to the brightness change value; the adjustment unit is used to adjust the CABC value according to the average brightness change. The invention can adjust different CABC values ​​according to different application programs, so as to achieve the effect of reducing power consumption.

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...
