Abstract: Embodiments of the present disclosure is directed to a method of controlling screen color temperature. The method includes: acquiring ambient light parameters according to a preset time interval, obtaining an ambient relative color temperature value corresponding to the ambient light parameter acquired at each acquisition time point, performing a weighted average process on the ambient relative color temperature value corresponding to the ambient light parameter acquired at each acquisition time point to obtain a target ambient color temperature value, determining a target screen color temperature value corresponding to the target ambient color temperature value and further a current screen color temperature value, and changing a color temperature value of the screen from the current screen color temperature value to the target screen color temperature value according to the screen color temperature value change time.
