Rear view mirror simulation

1. A method for exterior mirror simulation, for a motor vehicle having a reverse view switch and driven by a driver, whereby an image of a wide-angle lens having a field of view is recorded, and information collected by pixels of an optical sensor undergoes the following steps:

recording of the image;

determining distortion created by the wide-angle lens;

removing the distortion from the image;

selecting an image rectification algorithm;

applying the image rectification algorithm to subset of the total pixels in the image to create a rectified image;

storing the rectified image;

modifying the rectified image to a distorted rectified image representing the rectified image as viewed through a non-planar mirror only based on visible light information provided by the optical sensor;

displaying the distorted rectified image on a display;

adjusting the display device to an extended display when the motor vehicle is reversing to display more the distorted rectified image; and

enlarging the field of view in the display when the motor vehicle is being reversed.

2. A method as set forth in claim 1 including calculating the field of view of the driver prior to the step of applying the rectification algorithm.

3. A method as set forth in claim 1 wherein the display is pre-calibrated.

4. A method as set forth in claim 3 wherein the display is pre-calibrated to a type of mirror to be simulated.

5. A method as set forth in claim 1 including a step of adjusting the image on the display by selecting a subset of pixels in the display differing from those in the image.

6. A method as set forth in claim 1 wherein the step of applying the image rectification algorithm to subset of the total pixels in the image to create a rectified image includes the step of capturing a portion of the motor vehicle in the image to use as a reference for rectification.

7. A rear view assembly for a motor vehicle, said rear view assembly comprising:

a housing fixedly secured to the motor vehicle, said housing including an optical sensor housed therewith and a lens focusing light for said optical sensor to capture a wide-angle image, said optical sensor creating electrical signal representative of the focused light;

a display device operatively connected to said optical sensor for receiving said electrical signal and for displaying the electrical signal as a rear view image for a driver of the motor vehicle such that said rear view image includes distortions created by said lens;

a computational unit to identify and remove the image distortions created by said lens, said computational unit including a distortion simulator to distort the display of the rear view image only based on visible light information provided by said optical sensor to create a distorted display image such that the distorted display image appears to be created by a non-planar mirror; and

a reverse view switch to adjust said display device to an extended display after the image distortions have been removed from the rear view image and the display distortions have been added to the rear view image to create an extended distorted display image when the motor vehicle is and enlarging the field of view in the display when the motor vehicle is being reversed.

8. A rear view assembly as set forth in claim 7 wherein the distorted display image on said display device simulates a convex exterior mirror.

9. A rear view assembly as set forth in claim 7 wherein the distorted display image on said display device simulates an aspherical exterior mirror.

10. A rear view assembly as set forth in claim 7 wherein the distorted display image on said display device simulates an exterior mirror with additional lens.

11. A rear view assembly as set forth in claim 7 wherein the distorted display image on said display device simulates an adjustment of the view for the driver.

12. A method for exterior mirror simulation, for a motor vehicle having a reverse view switch and driven by a driver, whereby an image of a wide-angle lens having a field of view is recorded, and information collected by pixels of an optical sensor undergoes the following steps:

recording of the image;

removing the distortion from the image;

selecting an image rectification algorithm;

applying the image rectification algorithm to subset of the total pixels in the image to create a rectified image;

storing the rectified image;

modifying the rectified image to a distorted rectified image representing the rectified image as viewed through a non-planar mirror only based on visible light information provided by the optical sensor;

displaying the distorted rectified image on a display; and

enlarging the field of view in the display when the motor vehicle is being reversed.

13. A method as set forth in claim 12 including calculating the field of view of the driver prior to the step of applying the rectification algorithm.

14. A method as set forth in claim 12 wherein the display is pre-calibrated.

15. A method as set forth in claim 12 wherein the display is pre-calibrated to a type of mirror to be simulated.

16. A method as set forth in claim 12 including a step of adjusting the image on the display by selecting a subset of pixels in the display differing from those in the image.
