Abstract

A system and method combine digital television together with a digital video camera and controller unit for using a digital video camera together with a digital television set as a home security system that allows stranger detection, fire detection, motion detection, etc. The detection results are used to make further decisions such as display or record some of the scenes.

Claims

1. A security and surveillance system, comprising a control unit configured to:

determine a special event occurrence observed, including detecting a face using a function F_d according to;

2. The system of claim 1 wherein the control unit is configured to control the one or more of the digital video cameras, the television display, or a combination thereof based on user commands.

3. The system of claim 1 wherein the control unit is configured to process video streams from the digital video cameras, the video streams are tiled together to a proper resolution.

4. The system of claim 1 wherein the first camera is installed remote from and is connected to the television display.

5. The system of claim 1 wherein the control unit is configured to control one or more of the one or more of the digital video cameras, the television display, or a combination thereof based on the special event occurrence.

6. The system of claim 5 wherein the control unit is configured to receive a command to control the one or more of the digital video cameras, the television display, or a combination thereof and the decision making module.

7. The system of claim 6 wherein the control unit is configured to control the one or more of the digital video cameras, the television display, or a combination thereof further based on user commands from the remote control module.

8. The system of claim 7 further comprising a digital video recording device, coupled to the control unit, configured to record video signals from the one or more of the digital video cameras and plays back recorded video signals on the television display.

9. The system of claim 8 wherein the one or more of the digital video cameras, the television display, the digital video recording device, or a combination thereof exchange signals therebetween via the image and video processing module.

10. The system of claim 5 wherein the control unit is configured to process signals from the one or more of the digital video cameras before analysis and provide one or more of noise reduction, video selection and combining, scaling, and frame rate conversion.

11. The system of claim 10 wherein the control unit is configured to control the image and video processing module.

12. The system of claim 5 wherein the control unit is configured to perform one or more of stranger detection, fire detection and motion detection.

13. The system of claim 12 wherein the control unit is configured to:

detect as stranger a person, in a scene from the first camera, who is not registered in a database;

detect presence of fire in the scene from the first camera; and

detect presence of motion in scenes from the first camera.

14. The system of claim 13 wherein the control unit is configured to integrate the results from said detection modules and for providing the integrated results to the decision making module.

15. The system of claim 13 wherein the control unit is configured to:

detect an individual'"'"'s face in the scene from the first camera; and

classify the individual'"'"'s face as a stranger'"'"'s face when the individual'"'"'s face is not among images of registered individuals'"'"' faces.

16. A security and surveillance system, a control unit configured to:

determine a special event occurrence observed, including detecting a face using a function F_d according to;

17. The system of claim 16, wherein the control unit is configured to:

output a video signal from one or more cameras to the television display using a picture in picture function; and

start a recording on the digital recording device to record a video signal and setting an interval for recording a scene based on a detected motion in the scene.

18. The system of claim 16 wherein the control unit is implemented in the television display.

19. The system of claim 16 wherein the control unit is implemented as a stand alone device.

20. The system of claim 16 wherein the control unit is implemented in the digital recording device.

21. The system of claim 16 wherein the one or more digital video cameras includes a wireless camera having a receiving base station connected to the image and video processing module.

22. The system of claim 16 wherein the control unit is configured to perform one or more of stranger detection, fire detection, and motion detection.

23. A method of operation for a surveillance system comprising of:

receiving video signals from a digital video camera for feeding the video signals to a television display located in a home;

determining a special event occurrence observed with the digital video camera detecting based on the video signals includes detecting a face using a function F_d according to;

24. The method of claim 23 wherein the step of determining further includes the steps of:

stranger detection when a person, in a scene from a camera, is not registered in a database;

detecting fire in a scene from the camera; and

detecting presence of motion in scenes from the camera.

25. The method of claim 23 wherein the step of performing the intelligent task further includes the steps of starting to record a scene.

26. The method of claim 23, wherein the steps of performing the intelligent task includes the steps of:

feeding the video signals from the camera to the television display.
