The invention discloses a method and device for detecting a lens stain. The method comprises a step of selecting an interest area of an image, and selecting a test unit in the interest area, a step of obtaining the test pixel in each test unit and the brightness value of each reference pixel, and calculating the average brightness value of the test pixel in each test unit and the reference pixel and the variance of the brightness value, a step of comparing the variance and the variance threshold corresponding to the average brightness value obtained in advance, if the variance is larger than the variance threshold, judging the test pixel in the test unit as a stain, and outputting the pixel position of the stain. For an image which is gradually darkened in a radiating form from a center to an edge, the variance threshold corresponding to the center area with high brightness is smaller than the variance threshold corresponding to an edge area with low brightness, the slight stain of the center area can be easily detected, the edge area with a large variance is not wrongly judged as a stain, and the accuracy and efficiency of a test are improved.
