1. A method for performing one of detection, density determination, or classification of an aerosol in an environment using at least one image of the environment taken by a camera of a vehicle, comprising: in a first step, ascertaining a first value of a selected parameter of the at least one image using a first color filtering; in a second step, ascertaining a second value of the selected parameter one of: (i) without the first color filtering, or (ii) using a second color filtering different from the first color filtering; comparing the ascertained first and second values; and performing, as a function of the result of the comparison, the one of detection, density determination, or classification of the aerosol, wherein: the selected parameter is one of the average brightness value or the gradient of the pixels, the comparison of the first and second values is achieved by formation of at least one of a difference, a quotient, and a variance using gray value distribution data, the comparison of the first and second values is achieved by formation of a difference between the first and second values, the difference is compared to a first threshold value and a second threshold value higher than the first threshold vale, and the aerosol is one of detected or classified if the difference is higher than the first threshold value and lower than the second threshold value.
