Abstract

The invention relates to a method and a device for recognising a pulsing light source (7), in which a sequence of individual images is acquired with a light sensitive sensor (5). In an evaluation unit (6), all or at least some of the picture points of each individual image are examined with regard to at least one predefined feature. A gray value of any picture point depends on two or more charge levels of at least one of the photodetectors of the sensor (5) corresponding to the picture point at the ends of at least two integration intervals for the picture point. The at least two integration intervals for said picture point have different lengths. The examination comprises an examination of the picture points as to whether the picture points have gray values in a defined vicinity of one of at least one predefined gray value.
