Abstract

A method for manipulating image data in a digital image capture device includes forming two or more image processors, and providing the two or more image processors in the digital image capture device. The method further includes linking the two or more image processors to form an image processing chain, the image processing chain capable of manipulating image data in sequential and serial manners.

In a system aspect, the system includes a digital image capture device, the digital image capture device capable of processing digital image data through two or more image processors. The system further includes a central processing unit within the digital image capture device and capable of linking the two or more image processors to form an image processing chain, wherein the image processing chain manipulates the digital image data in sequential and serial manners.

Claims

1. A method for manipulating image data in a digital image capture device, the method comprising:

forming two or more image processors;

providing the two or more image processors in the digital image capture device; and

linking the two or more image processors to form an image processing chain (IPC), the IPC capable of manipulating image data in sequential and serial manners, the image processors in the IPC coordinated by an image processing backplane (IPB),

wherein the IPB comprises;

at least one data structure for storing information relating to the image processors of the IPC, and

a plurality of functions for initializing the IPC, installing an image processor into the IPC, signaling that all image processors are installed into the IPC, destroying the IPC, and updating the IPC,

wherein the IPB is capable of calling functions for defining, initializing, resetting, processing, controlling, obtaining a status of, and destroying an image processor.

2. The method of claim 1 wherein one of the IPC image processors comprises a linearization image processor.

3. The method of claim 1 wherein one of the IPC image processors comprises a bad pixel replacement image processor.

4. The method of claim 1 wherein one of the IPC image processors comprises a white balance image processor.

5. The method of claim 1 wherein one of the IPC image processors comprises an image reconstruction image processor.

6. The method of claim 1 wherein one of the IPC image processors comprises a color correction image processor.

7. The method of claim 1 wherein one of the IPC image processors comprises a color space conversion image processor.

8. The method of claim 1 wherein one of the IPC image processors comprises a sharpening image processor.

9. The method of claim 1 wherein one of the IPC image processors comprises a compression image processor.

10. A system for manipulating digital image data, the system comprising:

a digital image capture device, the digital image capture device capable of processing digital image data through two or more image processors; and

a central processing unit within the digital image capture device and capable of linking the two or more image processors to form an image processing chain (IPC), wherein the IPC manipulates the digital image data in sequential and serial manners, wherein the image processors in the IPC are coordinated by an image processing backplane (IPB),

wherein the IPB comprises;

at least one data structure for storing information relating to the image processors of the IPC, and

a plurality of functions for initializing the IPC, installing an image processor into the IPC, signaling that all image processors are installed into the IPC, destroying the IPC, and updating the IPC,

wherein the IPB is capable of calling functions for defining, initializing, resetting, processing, controlling, obtaining a status of, and destroying an image processor.

11. The system of claim 10 wherein one of the IPC image processors comprises a linearization image processor.

12. The system of claim 10 wherein one of the IPC image processors comprises a bad pixel replacement image processor.

13. The system of claim 10 wherein one of the IPC image processors comprises a white balance image processor.

14. The system of claim 10 wherein one of the IPC image processors comprises an image reconstruction image processor.

15. The system of claim 10 wherein one of the IPC image processors comprises a color correction image processor.

16. The system of claim 10 wherein one of the IPC image processors comprises a color space conversion image processor.

17. The system of claim 10 wherein one of the IPC image processors comprises a sharpening image processor.

18. The system of claim 10 wherein one of the IPC image processors comprises a compression image processor.

19. A computer readable medium containing program instructions for:

forming two or more image processors;

providing the two or more image processors in the digital image capture device; and

linking the two or more image processors to form an image processing chain, the image processing chain capable of manipulating image data in sequential and serial manners, the image processors in the IPC coordinated by an image processing backplane (IPB),

wherein the IPB comprises;

at least one data structure for storing information relating to the image processors of the IPC, and

a plurality of functions for initializing the IPC, installing an image processor into the IPC, signaling that all image processors are installed into the IPC, destroying the IPC, and updating the IPC,

wherein the IPB is capable of calling functions for defining, initializing, resetting, processing, controlling, obtaining a status of, and destroying an image processor.
