IMAGING SYSTEM FOR VEHICLE
First Claim
1. A vision system for a vehicle, said vision system comprising:
- a plurality of imaging sensors disposed at the vehicle, each having a respective exterior field of view and each capturing respective image data;
a display screen disposed in the vehicle and operable to display images for viewing by a driver of the vehicle, wherein said display screen is operable to display images derived from image data captured by said imaging sensors;
a processing system operable to process image data captured by said imaging sensors and to at least one of combine and manipulate image data captured by said imaging sensors to provide a three-dimensional representation of the exterior scene for display at said display screen;
wherein said processing system is operable to process said captured image data in accordance with a curved surface model;
wherein said processing system is operable to process said captured image data to provide the three-dimensional representation as if seen by a virtual observer from a first virtual viewing point exterior of the vehicle having a first viewing direction; and
wherein said processing system is operable to adjust said curved surface model when displaying the three-dimensional representation from a second virtual viewing point exterior of the vehicle having a second viewing direction to provide enhanced display of the images as if viewed from the second virtual viewing point.

Abstract
A vehicular vision system includes a plurality of imaging sensors disposed at the vehicle and a display screen disposed in the vehicle. A processing system is operable to process captured image data and to combine and/or manipulate captured image data to provide a three-dimensional representation of the exterior scene for display at the display screen. The processing system is operable to process the captured image data in accordance with a curved surface model, and is operable to process the image data to provide the three-dimensional representation as if seen by a virtual observer from a first virtual viewing point exterior of the vehicle having a first viewing direction. The processing system is operable to adjust the curved surface model when displaying the three-dimensional representation from a second virtual viewing point exterior of the vehicle having a second viewing direction to provide enhanced display of the images.

13. A vision system for a vehicle, said vision system comprising:
-
a plurality of imaging sensors disposed at the vehicle and having exterior fields of view, said imaging sensors capturing image data; a display screen for displaying images derived from said captured image data; a processing system that is operable to store raw image data in a main memory device to reduce an amount of data to be moved to the memory device; and wherein said processing system accesses and processes blocks of data and wherein said processing of said blocks of data comprises at least one of (a) de-mosaic processing of said image data to convert to RGB, YUV or YCrCb color space, (b) visibility enhancement processing and (c) merging of image data from two or more of said imaging sensors. - View Dependent Claims (14, 19, 20)

15. A vision system for a vehicle, said vision system comprising:
-
a plurality of imaging sensors disposed at the vehicle and having exterior fields of view, said imaging sensors capturing image data; a display screen for displaying images derived from said captured image data; a processing system that is operable to transform image data to produce a view of the exterior area surrounding the vehicle, and wherein said processing system is operable to select a portion of said transformed image data for transmitting to said display screen for displaying images at said display screen; and wherein, responsive to an indication that information outside of the selected portion of said transformed image data is to be displayed on said display screen, said processing system selects another portion of said image data and transmits said another portion of said image data for displaying images at said display screen. - View Dependent Claims (16, 17, 18)
