Abstract
A fog discrimination method is disclosed, including a capturing step, a calculation step, and a determining step. The capturing step includes capturing a sub-image of an image. The sub-image includes a light shield body image and a light shield stripe image. The calculation step includes calculating a maximum average grayscale value and a minimum average grayscale value of the sub-image; and calculating a fog function. The fog function is a function of the maximum average grayscale value and the minimum average grayscale value. The determining step includes determining whether the fog function is greater than or less than a threshold; and determining as being fogged when the fog function is less than the threshold.
