Rearview device simulation

1. A method for displaying and processing an image captured by an optical system used to simulate a rear-view system of a vehicle, the method comprising:

capturing the image;

calculating one or more of a size, a position, and a field of view of a region of interest (ROI) of the captured image;

calculating a blur factor for blurring the ROI;

processing the image by manipulating an image gradient of the ROI pixel by pixel using the blur factor to reduce at least one of a brightness or a contrast of one or more pixels of the ROI, and

displaying the processed image on a display,

wherein the manipulating of the image gradient of the ROI pixel by pixel comprises adjusting pixel contrast to achieve a less than 90 degree step function,

wherein the ROI comprises a plurality of regions, each region of the plurality of regions of the ROI being blurred and manipulated using a different nonzero blur factor so that each region is blurred to a different degree.

2. The method for displaying and processing as set forth in claim 1 , wherein the display on which the processed image is displayed is at least one of an internal vehicle dashboard display, an internal vehicle A-pillar display, and an external vehicle display at a side of the vehicle.

3. The method for displaying and processing as set forth in claim 1 , wherein one or more of the size, position, and field of view of the ROI is calculated based on one or more preset parameters.

4. The method for displaying and processing as set forth in claim 3 , wherein the one or more preset parameters are based on one or more regulations related to a required field of view, and the ROI is calculated as any region outside the required field of view.

5. The method for displaying and processing as set forth in claim 1 , wherein one or more of the size, position, and field of view of the ROI is calculated based on a user input.

6. The method for displaying and processing as set forth in claim 1 , wherein one or more of the size, position, and field of view of the ROI is calculated based on a vehicle input comprising at least one of a vehicle speed, a surrounding environment, a detected weather condition, a detected user or driver, a detected traffic condition, and a location of the display.

7. The method for displaying and processing as set forth in claim 1 , further comprising calculating a vehicle input comprising at least one of a vehicle speed, a surrounding environment, a detected weather condition, a detected user or driver, a detected traffic condition, and a location of the display.

8. The method for displaying and processing as set forth in claim 7 , wherein the calculating of the blur factor comprises calculating the blur factor using the calculated vehicle input.

9. The method for displaying and processing as set forth in claim 8 , wherein the calculated vehicle input is vehicle speed and the blur factor increases in response to an increase in the calculated vehicle speed.

10. The method for displaying and processing as set forth in claim 1 , wherein the manipulating of the image gradient of the ROI pixel by pixel comprises reducing the brightness and the contrast of each pixel in the ROI.

11. The method for displaying and processing as set forth in claim 1 , wherein the manipulating of the image gradient of the ROI pixel by pixel comprises at least one of applying a filter in the ROI, applying contrast via a tone reproduction curve, and desaturation of color in the ROI.

12. The method for displaying and processing as set forth in claim 1 , wherein the manipulating of the image gradient of the ROI pixel by pixel comprises adopting information from a first pixel to a second pixel and adopting information from the second pixel to the first pixel to achieve a blurriness effect.
