摘要
Image data are detected from the surroundings. At least one region of a detected image is evaluated to form a characteristic measurement value. A visibility is determined using a reference relating the measurement value to a visibility. A measurement value for the sharpness or contrast of the image may be used, and obtained from the differences of intensities of adjacent or neighboring pixels. Independent claims are included for the following; (1) an apparatus for estimating visibility; (2) a system for acquiring references.
