The invention concerns a device for improving the view in vehicles, in particular at night, bad weather and fog. In the process images of actual traffic scenes are recorded by a camera (2), which is sensitive outside the visible spectrum, and these images are reproduced in the visible spectrum in the vehicle via a display optic ( 6). According to the invention the type of object which is contained in a traffic scene recorded by the camera (2) is automatically classified according to type, and depending upon the type of the recognized object it is reproduced on the display optic (6) in an intensity and/or color, which corresponds to the intensity and/or color which the associated object typically has by daylight. The process facilitates the recognition by the vehicle operator of images of traffic scenes recorded outside the visible spectrum.

What is claimed is: 1. A visibility improving device for traffic situation recognition comprising: a vehicle mounted headlight emitting radiation outside the visible spectrum, a camera (2) sensitive to said radiation outside the visible spectrum, for recording video images of actual traffic scenes,
What is claimed is: 1. A visibility improving device for traffic situation recognition comprising: a vehicle mounted headlight emitting radiation outside the visible spectrum, a camera (2) sensitive to said radiation outside the visible spectrum, for recording video images of actual traffic scenes, a device (8) for recognizing types of objects contained in the traffic scene recorded by the camera (2), a device (10, 4) for assigning to a recognized type of object an intensity and/or a color which corresponds to the intensity and/or color which the associated object typically has by daylight, and an optical display in the vehicle for reproducing the recorded image representing the traffic situation in the visible spectrum including reproducing recognized types of objects with the intensity and/or the color assigned by the device (10, 4). 2. The visibility improving device as in claim 1, wherein device (8) for recognizing types of objects is programmed to recognize at least one of the following types of object: vehicle, person, animal, street, forest and meadow. 3. The visibility improving device as in claim 1, wherein the device for assigning intensity and/or a color (10, 4) receives location and outline information from said recognition device (8) and assigns color intensity and color to the object within said outline without modifying said outline. 4. The visibility improving device as in claim 1, wherein the device for assigning intensity and/or a color (10, 4) reads object color attributes programmed into an object color attribution memory. 5. The visibility improving device as in claim 4, wherein for color attribution the color matching device (10) receives input from at least one additional input selected from an external thermometer, clock, and rain sensor. 6. A process for improving the visibility in a vehicle, comprising: recording an image of an actual traffic scene by means of a camera which is sensitive outside the visible spectrum, automatically recognizing types of objects contained in the traffic scene recorded by the camera (2), reproducing the recorded image of the actual traffic scene, however in the visible spectrum, within the vehicle on an optical display (6), wherein objects recognized by type are reproduced in an intensity and/or color which corresponds to the intensity and/or color which the object typically has during daylight, whereby said display facilitates recognition of the traffic situation. 7. A process as in claim 6, further comprising illuminating the traffic scene with a headlight emitting non-visible light. 8. A process as in claim 6, wherein the outline, relative size, and relative motion of the object is not modified.
