Abstract

A method and system for capturing and transmitting image data streams. In one embodiment, the method includes capturing image data with a image sensor; creating a window within the image data and creating a detailed image data stream based on the windowed image data; reducing the image data and creating a contextual image data stream based on the reduced image data; and transmitting the detailed image data stream and the contextual image data stream.

Claims

1. A method of capturing and transmitting image data streams comprising the steps of:

capturing image data with a image sensor;

creating a window within the image data and creating a detailed image data stream based on the windowed image data;

reducing the image data and creating a contextual image data stream based on the reduced image data; and

transmitting the detailed image data stream and the contextual image data stream.

2. The method of claim 1, wherein the steps of windowing the image data and creating a detailed image data stream based on the windowed image data, and reducing the image data and creating a contextual image data stream based on the reduced image data, occur substantially in parallel.

3. The method of claim 1, wherein windowing the image data includes extracting a portion of the field of view of the image sensor.

4. The method of claim 1, wherein reducing the image data includes using the full field of view of the image sensor.

5. The method of claim 1, wherein reducing the image data includes reducing the resolution of the image data.

6. The method of claim 1, wherein reducing the image data includes reducing the frame rate of the image data.

7. The method of claim 1, wherein the data rate per unit area of the sensor field of view of the detailed image data stream is greater than the data rate per unit area of the sensor field of view of the contextual image data stream.

8. The method of claim 1, further comprising the steps of creating a second window with the image data and creating a second detailed image data stream based on the second windowed image data;

wherein the step of transmitting the image data streams includes transmitting the second detailed image data stream.

10. The method of claim 1, wherein the step of transmitting the image data streams further includes transmitting the data streams over Category 5 cable.

12. The method of claim 1, further comprising the steps of:

capturing image data with a second image sensor;

windowing the image data from the second image sensor and creating a second detailed image data stream based on the windowed image data from the second image sensor;

reducing the image data of the second image sensor and creating a second contextual image data stream based on the reduced image data from the second image sensor; and

transmitting the second detailed image data stream and the second contextual image data stream.

14. The method of claim 12, further comprising the step of identifying an object in at least one of the image data streams.

15. The method of claim 14, further comprising the step of controlling the first image sensor and the second image sensor based on the identification of the object such that at least one of the first detailed image data stream and the second detailed image data stream provides information about the object.

17. The method of claim 12, further comprising the step of substantially maintaining the synchronization of the first image sensor and the second image sensor.

18. The method of claim 12, further comprising the step of providing a signal based on an orientation of the first image sensor relative to the orientation of the second image sensor.

20. The method of claim 12, further comprising the steps of:

capturing image data with a third image sensor;

windowing the image data from the third image sensor and creating a third detailed image data stream based on the windowed image data from the third image sensor;

reducing the image data of the third image sensor and creating a third contextual image data stream based on the reduced image data from the third image sensor; and

transmitting the third detailed image data stream and the third contextual image data stream.

21. A system for capturing and transmitting image data streams comprising:

an image sensor processor having

a first processor means for creating a window within the image data and creating a detailed image data stream based on the windowed image data,

a second processor means for reducing the image data and creating a contextual image data stream based on the reduced image data, and

means for transmitting the detailed image data stream and the contextual image data stream.

22. The system of claim 21, wherein the first processor means and the second means perform substantially in parallel.

23. The system of claim 21, wherein the first processor means extracts a portion of the field of view of the image sensor.

24. The system of claim 21, wherein the second processor means uses the full field of view of the image sensor.

25. The system of claim 21, wherein the second processor means reduces the resolution of the image data.

26. The system of claim 21, wherein the second processor means reduces the frame rate of the image data.

27. The system of claim 21, wherein the data rate per unit area of the sensor field of view of the detailed image data stream is greater than the data rate per unit area of the sensor field of view of the contextual image data stream.

29. The system of claim 21, wherein the means for transmitting includes transmitting the image data streams over Category 5 cable.

31. The system of claim 21, further comprising:

a second image sensor processor having

a first processor means for creating a window within the image data and creating a second detailed image data stream based on the windowed image data,

a second processor means for reducing the image data and creating a second contextual image data stream based on the reduced image data, and

means for transmitting the second detailed image data stream and the second contextual image data stream.

32. The system of claim 31, further comprising an image server adapted to control the first image sensor processor and the second image sensor processor, wherein the image server includes a means for identifying an object in at least one of the image data streams.
