Abstract

Disclosed are various systems and methods for processing and displaying video in a vehicle. In one embodiment, a vehicle video system is provided that comprises cameras and monitors mounted in a vehicle. Each of the cameras generates a video image, the cameras including a plurality of visible light cameras and a plurality of night vision cameras. The vehicle video system also includes a video processing unit that is configured to select at least two subsets of the cameras and to generate an output video image that incorporates at least one of the video images generated by at least one of the cameras in a first one of the subsets. The vehicle video system also includes a digital video recording processor included in the video processing unit that cyclically records a predefined time period of the output video image.

Claims

1. A vehicle video system, comprising:

a plurality of cameras mounted in a vehicle, each of the cameras generating a video image, the cameras including a plurality of visible light cameras and a plurality of night vision cameras;

a plurality of monitors;

a video processing unit, each of the cameras and each of the monitors being electrically coupled to the video processing unit, the video processing unit being configured to select at least two subsets of the cameras;

the video processing unit generating an output video image that incorporates at least one of the video images generated by at least one of the cameras in a first one of the subsets; and

a digital video recording processor included in the video processing unit that cyclically records a predefined time period of the output video image.

2. The vehicle video system of claim 1, wherein the video processing unit further comprises:

a digital video recording mode in which the output video image is applied to the digital video recording processor, and a video output of the digital video recording processor is applied to at least one of the monitors, the digital video recording processor recording the output video image; and

a video bypass mode in which the output video image is applied directly to the at least one of the monitors, wherein the output video image bypasses the digital video recording processor.

3. The vehicle video system of claim 2, further comprising a video image selector electrically coupled to the video processing unit, the video image selector being configured to provide a control input to the video processing unit, the control input selecting between the digital video recording mode and the video bypass mode.

4. The vehicle video system of claim 1, further comprising a video image selector electrically coupled to the video processing unit, the video image selector being configured to generate a plurality of control inputs to manipulate the operation of the video processing unit and the digital video recording processor.

5. The vehicle video system of claim 4, wherein the digital video recording processor is further configured to implement a video hop in the output video image to replay a portion of the output video image associated with a predefined period of time relative to a current position in the output video image, wherein the video hop is implemented in response to a predefined one of the control inputs generated by the video image selector.

6. The vehicle video system of claim 4, wherein the digital video recording processor is further configured to pause the output video image, wherein the pause of the output video image is implemented in response to a predefined one of the control inputs generated by the video image selector.

7. The vehicle video system of claim 4, wherein the digital video recording processor is further configured to implement a number of forward playing speeds to view the output video image on at least one of the monitors, wherein the forward playing speeds are selected in response to a predefined one of the control inputs generated by the video image selector.

8. The vehicle video system of claim 4, wherein the digital video recording processor is further configured to implement a number of reverse playing speeds to view the output video image on at least one of the monitors, wherein the reverse playing speeds are selected in response to a predefined one of the control inputs generated by the video image selector.

9. The vehicle video system of claim 1, wherein the video processing unit is further configured to record a time stamp in the output video image stored on a medium, the time stamp being generated by a detection of motion in the output video image.

10. A method for video control and display in a vehicle, wherein a plurality of cameras and a plurality of monitors are mounted in the vehicle, the cameras including a plurality of visible light cameras and a plurality of night vision cameras, each one of the cameras generating a video image, the method comprising the steps of:

selecting at least two subsets of the cameras;

generating an output video image that incorporates at least one of the video images generated by at least one of the cameras in a first one of the subsets; and

cyclically recording a predefined time period of the output video image.

11. The method of claim 10, wherein each of the cameras and each of the monitors is coupled to a video processing unit that includes a digital video recording processor that records the output video image, the method further comprising the steps of:

alternatively operating the video processing unit in one of a digital video recording mode and a video bypass mode, wherein the output video image is applied to the digital video recording processor, and a video output of the digital video recording processor is applied to at least one of the monitors when in the digital video recording mode; and

the output video image is applied directly to the at least one of the monitors, thereby bypassing the digital video recording processor when in the video bypass mode.

12. The method of claim 11, further comprising the step of manipulating a video image selector electrically coupled to the video processing unit to generate a control input that is applied to the video processing unit, the control input selecting between the digital video recording mode and the video bypass mode.

13. The method of claim 10, wherein each of the cameras and each of the monitors is coupled to a video processing unit that includes a digital video recording processor that records the output video image, the method further comprising the step of manipulating a video image selector electrically coupled to the video processing unit to generate a plurality of control inputs that are applied to the video processing unit, the control inputs manipulating an operation of the video processing unit and the digital video recording processor.

14. The method of claim 13, further comprising the step of manipulating the video image selector to generate one of the control inputs that directs the digital video recording processor to implement a video hop in the output video image to replay a portion of the output video image associated with a predefined period of time relative to a current position in the output video image.

15. The method of claim 13, further comprising the step of manipulating the video image selector to generate one of the control inputs that directs the digital video recording processor to pause the output video image.

16. The method of claim 13, further comprising the step of manipulating the video image selector to generate one of the control inputs that directs the digital video recording processor to implement a playback of the output video image at one of a plurality of forward playing speeds on at least one of the monitors.

17. The method of claim 13, further comprising the step of manipulating the video image selector to generate one of the control inputs that directs the digital video recording processor to implement a playback of the output video image at one of a plurality of reverse playing speeds on at least one of the monitors.
