METHOD FOR PROVIDING A CURRENT BRIGHTNESS VALUE RELATING TO AN AMBIENT BRIGHTNESS, DETECTION DEVICE AND MOTOR VEHICLE

Technologies and techniques for providing a current brightness value relating to an ambient brightness, wherein at least one first raw brightness value and temporally thereafter at least one second raw brightness value are detected using at least one brightness sensor. An averaging may be carried out at least for the at least one second raw brightness value together with at least the at least one first raw brightness value, and a result of the averaging being provided as a current mean brightness value. A gradient limitation is carried out for the current mean brightness value, in which a deviation of the current mean brightness value from at least one previously provided brightness value is limited to at least one maximum permissible amount if the deviation of the current brightness mean value from the at least one previously provided brightness value is greater than the at least one maximum permissible amount.
