The method includes: detecting (S110) current screen brightness of a screen subjected to a blue light filtering operation; determining (S120) a reconstruction proportion of RGB optical spectral energy corresponding to the 00 current screen brightness and a target color temperature to be met according to pre-learned RGB optical spectral energy distribution information; and adjusting (S130) the RGB optical spectral energy according to the reconstruction proportion, so as to enable the RGB O optical spectral energy of the screen subjected to a blue light filtering operation to meet the target color temperature.
