Abstract

A vehicular vision system includes a rearview video camera and a video processor operable to process captured video image data that includes at least a left zone image data set, a middle zone image data set and a right zone image data set. A single video display screen displays video images and includes a left display region at a left portion, a right display region at a right portion, and a middle display region between the left and right display regions. The display screen is operable to use each display region to display video images derived from the respective zone image data set. When the display screen is displaying video images at the right or left display region that are derived from the respective zone image data, the single video display screen does not display video images representative of the other zone image data at the other display region.

First claim

The invention claimed is:

1. A vehicular vision system comprising:
a rearview video camera at a rear portion of a vehicle;
a video processor operable to process video image data captured by said rearview video camera, wherein said video image data comprises at least a left zone image data set, a middle zone image data set and a right zone image data set;
wherein said left zone image data set comprises image data captured by said rearview video camera of a left zone that encompasses where another vehicle may at least one of (i) approach from the rear of the equipped vehicle in a left side lane adjacent to the equipped vehicle and (ii) overtake the equipped vehicle in a left side lane adjacent to the equipped vehicle;
wherein said right zone image data set comprises image data captured by said rearview video camera of a right zone that encompasses where another vehicle may at least one of (i) approach from the rear of the equipped vehicle in a right side lane adjacent to the equipped vehicle and (ii) overtake the equipped vehicle in a right side lane adjacent to the equipped vehicle;
wherein said middle zone image data set comprises image data captured by said rearview video camera of a middle zone between the left and right zones that encompasses a road lane being traveled on by the equipped vehicle, and wherein the middle lane is disposed between the left side lane and the right side lane;
a single video display screen for displaying video images;
wherein said single video display screen comprises a left display region at a left portion of said single video display screen and a right display region at a right portion of said single video display screen;
wherein said single video display screen comprises a middle display region between said left display region and said right display region;
wherein said left display region, said middle display region and said right display region comprise separate portions of said single video display screen;
wherein said single video display screen is operable to use said left display region to display video images derived from said left zone image data set, is operable to use said middle display region to display video images derived from said middle zone image data set, and is operable to use said right display region to display video images derived from said right zone image data set;
wherein said single video display screen is operable to display video images at said left display region of said single video display screen that are derived from said left zone image data set captured by said rearview video camera in order to display video images representative of the scene occurring at the left side lane at the left side of the equipped vehicle responsive to at least one of (a) actuation of a left turn signal indicator of the equipped vehicle, (b) detection of another vehicle in or approaching the left side lane adjacent to the equipped vehicle and (c) a lane departure warning system of the equipped vehicle;
wherein, when said single video display screen is displaying video images at said left display region that are derived from said left zone image data, said single video display screen does not display video images representative of said right zone image data at said right display region;
wherein said single video display screen is operable to display video images at said right display region of said single video display screen that are derived from said right zone image data set captured by said rearview video camera in order to display video images representative of the scene occurring at the right side lane at the right side of the equipped vehicle responsive to at least one of (a) actuation of a right turn signal indicator of the equipped vehicle, (b) detection of another vehicle in or approaching the right side lane adjacent to the equipped vehicle and (c) a lane departure warning system of the equipped vehicle; and
wherein, when said single video display screen is displaying video images at said right display region that are representative of said right zone image data, said single video display screen does not display video images representative of said left zone image data at said left display region.

2. The vehicular vision system of claim 1 , wherein said single video display screen displays an icon to enhance the driver's cognitive awareness of the images displayed at the display region displaying.

3. The vehicular vision system of claim 1 , wherein said middle display region of said single video display screen displays an iconistic warning responsive to detection of another vehicle in the left side lane or right side lane adjacent to the equipped vehicle.

4. The vehicular vision system of claim 1 , wherein said single video display screen comprises a reconfigurable thin film transistor liquid crystal screen that is backlit by a plurality of white light-emitting light emitting diodes.

5. The vehicular vision system of claim 4 , wherein said single video display screen is disposed in an interior rearview mirror assembly of the equipped vehicle and behind a transflective mirror reflector of a transflective mirror reflective element of said interior rearview mirror assembly, and wherein any one of said left, middle and right display regions of said single video display screen, when displaying video images, is viewable by a driver of the equipped vehicle and is covert to the driver of the equipped vehicle when not displaying video images.

6. The vehicular vision system of claim 5 , wherein said backlit liquid crystal display screen comprises at least about 85,000 individually addressable pixels.

7. The vehicular vision system of claim 1 , comprising dynamic contrast control of said single video display screen.

8. The vehicular vision system of claim 7 , wherein said dynamic contrast control is operable to increase contrast within individual video image frames when the video screen backlighting is locally dimmed.

9. The vehicular vision system of claim 1 , wherein said single video display screen is disposed in an interior rearview mirror assembly of the equipped vehicle and behind a transflective mirror reflector of a transflective electrochromic mirror reflective element of said interior rearview mirror assembly, and wherein any one of said left, middle and right display regions of said single video display screen, when displaying video images, is viewable by a driver of the equipped vehicle and is covert to the driver of the equipped vehicle when not displaying video images.

10. The vehicular vision system of claim 9 , wherein said video processor is operable to at least (a) provide on screen display capability, (b) provide video decoding, (c) at least partially control dimming of said transflective electrochromic mirror reflective element, and (d) at least partially control the intensity of said single video display screen.

11. The vehicular vision system of claim 9 , wherein said interior rearview mirror assembly is configured to selectively receive at least one accessory module therein to update said interior rearview mirror assembly to provide at least one new function or feature.

12. The vehicular vision system of claim 1 , comprising a forward viewing camera disposed at a front portion of the equipped vehicle having a forward field of view forward of the equipped vehicle in a direction of forward travel of travel of the equipped vehicle.

13. The vehicular vision system of claim 12 , wherein said video processor processes image data captured by said forward viewing camera to detect and recognize a road sign ahead of the equipped vehicle, and wherein said single video display screen displays an iconistic rep
