In modern cars Driver Assistance Systems (DAS) became common in the last few years. Whereas systems like the anti-lock brake system or the electronic stability systems are state of the art meanwhile, camera based DAS are actually being developed and can be seen more and more in series cars. These camera based systems can be divided roughly in two types: forward-looking cameras and cameras for low speed manoeuvring. Within this paper the focus will be put on the forward-looking cameras and the applications which will be enabled by such a sensor. This type of camera covers the medium range in front ofthe car. Typically it contains a CMOS sensor with a VGA-like resolution. Whereas the Lane Departure Warning (LDW) was one ofthe first functions in this area and can actually be seen in some series cars, there are several additional applications which can benefit from such a sensor. Conceivable are functions like Traffic Sign Recognition (TSR - e.g. for speed regulating signs), Object Detection (OD) or support for light functions. High beam assist for example switches between low and high beam depending on the presence of other road users in front of the vehicle. Beginning with adaptive and glare-free high beam we will see lighting systems perfectly adapting the light distribution to the driving environment, focussing the driver's alertness to hazard areas (marking light) or even projecting information onto the road (pixel light) in the future. Object detection e.g. can be used to support distance or collision warning systems. The upcoming regulations concerning the pedestrian protection might be another field of interest for such functionality. Installing an own camera for multiple ofthese application is neither reasonable from a mechanical nor from a commercial point ofview. Therefore the idea ofusing one camera for several customer functionalities suggests itself. Analysing the precise requirements ofeach of these applications in more detail it becomes obviously that the communality is not that great as it looks at first sight. Questions e.g. like the adequate viewing angle, the number and exposure of frames and the need of colour information have to be answered in a way that satisfies the demands of all chosen applications. Besides that, the question ofthe right hardware platform is of importance due to the high computational demands of the image processing functions.
