摘要： The disclosure discloses a method and apparatus for adjusting color temperature based upon fuzzy control. The method for adjusting color temperature based upon fuzzy control includes: determining an initial color temperature value of a screen of an terminal device according to an illumination intensity of ambient light when the screen is lightened; obtaining a percentage of eyelid closure over the pupil, over time, PERCLOS of a user, and the illumination intensity of ambient light at a preset periodicity; and determining a target color temperature value corresponding to the current PERCLOS of the user, and the current illumination intensity of ambient light according to a preset fuzzy rule, and adjusting the screen to the target color temperature value, wherein taking the PERCLOS, and the illumination intensity of ambient light as input signals, and the color temperature as an output signal according to the preset fuzzy rule.
