Abstract: A video image display (1) for a vehicle environment surveillance unit (0). The environment information is acquired by a camera (3) and processed into image information by a computer or processor (2). The produced image information is then displayed for the vehicle operator on a video image display (1). In order to be able to inform the vehicle operator regarding a malfunction (for example, a static image), acquired image information is stored in an intermediate memory (4). The most recently recorded image is then compared with the image information in intermediate memory using an image processing algorithm (5) and in the case that impermissible deviations are detected the displayed video image is modified or the video display is switched off. In the framework of the comparison of the image information, additional vehicle operating parameters (6) are taken into consideration, in order that a reliable check of the functioning of the video image display becomes possible.

Abstract: The invention concerns an automobile display unit, an automobile infrared night vision device and an automobile with such a display unit or, as the case may be, with such an infrared night vision device. The display includes an image processing unit which processes the image data supplied to it such that contiguous areas of maximal light intensity are recognized and these image data are adapted to the extent that they are at least partially replaced by image data with reduced light intensity values. These changed image data are supplied to the display, which reproduces these image data. This display unit makes possible a reduction or a prevention of blinding by brilliant light, which is particularly disturbing in a case of display of infrared night vision image information.
