Abstract: The invention relates to a method for recognizing a band-limiting malfunction of a camera (3) of a motor vehicle (1), in which during the operation of the motor vehicle (1) an image (12) of a measurement object (9), which is external to the motor vehicle, is captured by means of the camera (3) arranged on the motor vehicle (1), and in the image (12) a point spread function (14) is determined on the basis of a brightness distribution (16) along a profile through a pixel with a brightness, which exceeds a brightness threshold value, of the measurement object (13) shown in the image (12), and on the basis of the determined point spread function (14) a property value of a property of the camera (3) is determined, and the band-limiting malfunction of the camera (3) is recognized, in case the property value of the camera (3) is smaller than a property threshold value.
