摘要： An electronic apparatus and a backlight brightness control method thereof are provided. The control method includes the following steps. Detection of an ambient brightness for the electronic apparatus is made to output an ambient brightness signal. Next, whether to adjust the backlight brightness for the display is determined according to a comparison between the ambient brightness signal and a current backlight brightness. If the comparison result indicates that the ambient brightness decrement is lower than a decrement threshold, then an adjustment value is selected from a plurality of step sizes according to the current backlight brightness to decrease the backlight brightness gradually, so that the backlight brightness changes towards a target backlight brightness corresponding to the ambient brightness signal. The step sizes include a first step size and a second step size. The backlight brightness for the display is adjusted according to the current backlight brightness and the adjustment value.
