Abstract

Arrangement for a motor vehicle with a camera and a display device for capturing and displaying an image of the surroundings of the motor vehicle and for displaying graphically representable information, such as for example guide lines, reference texts or the like, with a means for superimposing the image with the information, wherein means for superimposing changes values of the pixels at the points of the image, at which the information is displayed, information pixels, as a function of the values captured by the camera.

Claims

1. A motor vehicle camera and display device for capturing and displaying an image of the surroundings of the motor vehicle and for displaying graphically representable information, comprising:

a camera, said camera generating original values for each of a plurality of pictures for showing an image depicting the surroundings of the vehicle;

a processor, said processor configured to generate separate pixel values for graphic information on a display having a plurality of pixels;

said processor being further configured to superimposed said original values for pixels showing the surroundings of the vehicle and said pixel values for said graphic information such that said image of the vehicle surroundings remains visible through pixels comprising said display of said graphic information, on said multi pixel display.

2. The apparatus of claim 1 wherein said graphic information is guidelines.

3. The apparatus of claim 1 wherein said graphic information is text.

4. The apparatus of claim 1 wherein said super imposition is by adding, subtracting or multiplying pixel values.

5. The apparatus of claim 1 wherein said super imposing is by varying at least one of a color value and a brightness value for each pixel displaying both said graphic information and said original value of the image.

6. The apparatus of claim 1 wherein said super imposing is by varying one of a voltage of a frequency.
