Claim 4:
5. The method according to claim 1, wherein determining the visible light illuminance of the current imaging picture by utilizing the color temperature value and the infrared light contribution ratio of the picture brightness obtained based on the white balance statistical information of the current imaging picture comprises:
acquiring a fourth correction factor corresponding to the color temperature value; and
correcting, by utilizing the fourth correction factor, the visible light illuminance obtained based on a visible light contribution ratio and total ambient light illuminance to obtain the first visible light illuminance; wherein the visible light contribution ratio is obtained by utilizing the infrared light contribution ratio, and the total ambient light illuminance is obtained based on current exposure statistical information.
