Abstract
A method for determining ambient light intensity includes: acquiring a plurality of light sensing integral values obtained by sampling light intensity with a predetermined light sensing collecting time window and a predetermined sampling frequency through a photosensitive element, wherein the light sensing collecting time window is greater than a screen blanking time of a terminal; determining a minimum light sensing integral value and a maximum light sensing integral value in the plurality of light sensing integral values; determining a light sensing integral value of a photosensitive element which corresponds to an ambient light according to the maximum light sensing integral value, the light sensing collecting time window, the minimum light sensing integral value and the screen blanking time; and determining the ambient light intensity according to the light sensing integral value of the photosensitive element which corresponds to the ambient light and a predetermined light intensity.
