Abstract
A first brightness value and a second brightness value are determined. The first brightness value relates to display performed by the display during a display time window. The second brightness value relates to an off state of the display during an off time window. The display is off during the off time window. A first drop depth value is determined according to the first brightness value and the second brightness value. A second ambient brightness value is acquired by adjusting a first ambient brightness value detected by the light sensor based on a brightness adjusting model acquired under predetermined ambient light and the first drop depth value.
