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 a display device for capturing and displaying an image of the surroundings of the motor vehicle and for displaying graphically representable information, comprising:

a means for superimposing the image with the information, wherein said means for superimposing changes values of the pixels at the points of the image, at which the information is displayed, by changing a plurality of information pixels, as a function of the values captured by the camera.

2. Arrangement according to claim 1, wherein the means for superimposing changes the brightness, the colour and/or the saturation of the information pixels as values.

3. Arrangement according to claim 1 wherein the means for superimposing changes the values of the information pixels by the same amount.

4. Arrangement according to claim 1 wherein the means for superimposing changes the values of the information pixels by an amount which depends on the value of this pixel captured by the camera.

5. Arrangement according to one of claim 1 wherein the means for superimposing is part of the camera.

6. Arrangement according to one of claim 1 wherein the means for superimposing is part of an image sensor of the camera.

7. Arrangement according to claim 6, wherein an initial value for integration indicating the change can be assigned to photosensitive elements of the image sensor, which are assigned to one of the information pixels, at the start of a particular integration time.

8. Arrangement according to claim 6 wherein after producing a digital image of the surroundings, the values of the information pixels can be changed, in particular by multiplication, addition or subtraction.

9. Arrangement according to one of claim 6 wherein the coordinates of the information pixels can be stored in the image sensor or an external memory, for example an EEPROM.

10. Arrangement according to one of claim 1 wherein the brightness value of an analog signal of the image of the surroundings can be changed by raising or lowering.

11. Arrangement according to claim 1 wherein said graphically represented information displayed includes a guideline.

12. Arrangement according to claim 1 wherein said graphically represented information displayed includes a text.
