Abstract
A method for recognizing an intensity of an aerosol in a field of view of a camera of a vehicle includes: reading in image information of an image of the camera, providing a color indicator value for at least one subsection of the image, the color indicator value representing a relation between (i) a first parameter representing a value obtained with application of a first color filter to the image information in the subsection, and (ii) a second parameter representing a value obtained without application of a color filter, or with application of a second color filter differing from the first color filter, and providing a gradient indicator value representing a brightness difference of a different image region of the image, an aerosol intensity value being determined using the color indicator and the gradient indicator values.

14. A method for determining an intensity of an aerosol in a field of view of a camera of a vehicle, comprising:
-
reading in image information of an image taken by the camera; providing (i) a color indicator value for at least one selected subsection of the image taken by the camera, and (ii) a gradient indicator value, wherein the color indicator value represents a relation between a first parameter and a second parameter, wherein the first parameter represents a value obtained with application of a first color filter to the image information in the subsection, and the second parameter represents a value obtained one of (a) without application of a color filter, or (b) with application of a second color filter differing from the first color filter, to the image information in the subsection, and wherein the gradient indicator value represents a brightness difference, derived from the image information, of a different image region of the image taken by the camera; and determining an aerosol intensity value using the color indicator value and the gradient indicator value in order to determine the intensity of the aerosol in the field of view of the camera of the vehicle. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
