A METHOD OF CONTROLLING THE EXPOSURE OF STATIONARILY MOUNTED VIDEO CAMERAS IS DISCLOSED RENDERING IT POSSIBLE TO OBTAIN OPTIMAL EXPOSURE ALSO IN DIFFICULT LIGHTING SITUATIONS. TO THIS END, MEASURING RANGES OF THE IMAGE ARE EVALUATED AND BASED ON THE SAID EVALUATION A CORRECTION FACTOR INFLUENCING THE EXPOSURE PARAMETERS OF THE CAMERA IS CALCULATED.(FIG. 4)
