First generation night vision enhancement systems with image presentation in the dashboard have been introduced on the market. Far infrared and near infrared systems are currently competing technologies. The camera picture is presented either with a Head-up display on the windscreen or in the dashboard region. An arbitrarily configurable LC display located in the instrument cluster was found to meet best the requirements of a quick and distraction-free reading. A precondition for a quick recognition and identification of relevant obstacles is a high-contrast and brilliant picture quality. To achieve this, picture quality improvement means have been applied. Such a setup has been selected for the new Mercedes S-class. A comparison of the technology and of the aspects of image representation and image processing shows that the NIR system is widely superior on almost all criteria. Especially the costs represent an important aspect. The NIR technology enjoys at a long term basis a massive cost benefit due to the low price of the video camera and due to its concurrent usage by several applications. Furthermore, research has shown that although the wider reach of the FIR system represents an increase in comfort, this does not automatically translate into any considerable plus in term of safety. The evolution of night vision functions is a process which depends on one hand on the development of hardware and software technologies, on the other hand on the acceptance of each driver and the overall contribution to the communities in reducing fatalities.
