Abstract: An electronic device is disclosed. The electronic device includes a display unit, a light sensor, and a processor. The display unit has a brightness value. The light sensor senses an ambient light to generate a light intensity signal. The processor is coupled to the display unit and the light sensor and accesses a program instruction from a memory to perform the following steps: continuously receiving the light intensity signal from the light sensor; smoothing a plurality of light intensity signals to generate a plurality of smoothing signals; and maintaining the brightness value of the display unit for a preset time period and then determining whether to adjust the brightness value when a difference generated by subtracting a previous smoothing signal of a target smoothing signal of the smoothing signals from the target smoothing signal is less than the first threshold or greater than the second threshold.
