A method for adjusting an ambient light sensor includes: acquiring a color temperature of light received by the ambient light sensor; and adjusting an output light intensity of the ambient light sensor according to the color temperature to enable output light intensities of the ambient light sensor to be consistent under received light with different color temperatures. The ambient light sensor includes: an acquiring device, configured to acquire a color temperature of light received by the ambient light sensor; and an adjuster, configured to adjust an output light intensity of the ambient light sensor according to the color temperature acquired by the acquiring device to enable output light intensities of the ambient light sensor to be consistent under received light with different color temperatures.
