The backlight value of is the backlight value corresponding to the backlight progress bar when the user stops operating the backlight progress bar. The backlight value refers to the backlight brightness value.

S12, when it is determined that the ambient light sensitivity value of the terminal changes, calculate the backlight value corresponding to the current ambient light sensitivity value according to the ambient light sensitivity value when the operation occurs and the backlight value before and after the operation.

In this embodiment, the light sensitivity value collected by the ambient light sensitivity can be obtained according to a set time period or in real time, and it is detected whether the change amount of the ambient light sensitivity value obtained this time relative to the ambient light sensitivity value obtained last time reaches If the threshold is set, it is determined that the ambient light sensitivity value has changed.
