Abstract

A vision enhancement system for a vehicle includes a camera (22) and a display (20). The camera (22) and display (20) are coupled to an interior of the vehicle. The camera (22) is configured to view the interior of the vehicle and to generate a video signal representative of the interior of the vehicle. The display (20) is coupled to the interior of the vehicle and coupled to the camera (22). The display (20) is configured to display the video signal.

Claims

1. A method of providing integrated audio and video communication between the front and rear seat areas of a vehicle, comprising:

receiving operator input at an operator input device mounted in the front seat area of the vehicle; and

in response to the received operator input, activating a video system to provide video signals of the rear seat area of the vehicle to a display in the front seat area of the vehicle and activating an audio system to provide audible signals between the front and rear seat areas of the vehicle.

2. The method of claim 1, further comprising receiving audio signals at a microphone in the front seat of the vehicle and providing the audio signals to a speaker mounted in the rear seat area of the vehicle.

3. The method of claim 1, wherein a single operator input activates both the video system and the audio system to allow communication between a front seat passenger and a rear seat passenger.

4. The method of claim 1, wherein, if one of the video and audio systems is already activated, the received operator input activates the other of the video and audio systems.

5. The method of claim 1, wherein the activating occurs substantially simultaneously.

6. The method of claim 1, wherein the operator input is received from a video system button and an audio system button.

7. The method of claim 1, further comprising receiving exterior video signals from an exterior area of the vehicle and, in response to a received operator input, displaying the exterior video signals on the display.

8. The method of claim 1, fixer comprising providing illumination to the rear seat area of the vehicle in response to a received operator input.

9. A vision enhancement system for a vehicle, the vehicle having an interior, comprising:

a camera configured to view a rear seat area of the vehicle interior and to generate a video signal representative of the rear seat area of the vehicle interior;

a display coupled to the camera, wherein the display is configured to display the video signal;

a light source positioned proximate the rear seat area of the vehicle interior configured to illuminate the rear seat area; and

an operator input device, wherein the display is configured to display the video signal in response to operator actuation of the operator input device and wherein the light source is automatically turned on when the video signal is displayed using the operator input device.

10. The vision enhancement system of claim 9, wherein the display is mounted in the front seat area of the vehicle.

11. The vision enhancement system of claim 9, further comprising a video control panel housing the camera, display, and operator input device, wherein the video control panel is mounted in the roof or headliner of the vehicle.

12. The vision enhancement system of claim 9, further comprising a computer coupled to the display configured to provide operation data to the display.

13. The vision enhancement system of claim 9, further comprising a second operator input device configured to turn the light source on and off in response to operator actuation of the second operator input device.

14. The vision enhancement system of claim 9, wherein the light source is mounted to a roof of the vehicle proximate a side of the vehicle.
