Abstract

An image processing system uses centralized image correction data to process digital images. The image processing system includes a centralized database for storing image correction data for imaging devices. An image processor that receives image data representing an image captured by one of the imaging devices accesses the centralized database with a key associated with the imaging device to retrieve the image correction data for the imaging device. The image processor processes the image data using the retrieved image correction data to correct the image data by reducing various noise components in the image.

Claims

1. An image processing system for processing images captured by imaging devices, comprising:

a centralized database for storing image correction data for each of said imaging devices; and

an image processor for receiving original image data representing an image captured by one of said imaging devices and a key associated with said one of said imaging devices, wherein said image processor is operable to access said centralized database to retrieve said image correction data for said one of said imaging devices using said key and process said original image data using said image correction data for said one of said imaging devices to produce corrected image data representing said image.

2. The system of claim 1, wherein said one of said imaging devices includes an image sensor operable to receive light from a scene and produce said original image data representing said image thereof and a lens operable to focus said light on said image sensor.

3. The system of claim 2, wherein said image correction data includes dark current correction data for removing dark current in said original image data produced as a result of defects in said image sensor.

4. The system of claim 2, wherein said image correction data includes color correction data for optimizing color in said original image data by compensating for defects in a color filter array associated with said image sensor.

5. The system of claim 2, wherein said image correction data includes lens correction data for reducing distortion in said original image data produced as a result of defects in said lens.

6. The system of claim 1, wherein said key includes an identifier for said imaging device.

7. The system of claim 1, wherein said imaging device is incorporated on an electronic device, and wherein said key includes an identifier for said electronic device.

8. The system of claim 1, wherein said image processor is implemented in a server connected to receive said original image data and said key from said one of said imaging devices via a data network.

9. The system of claim 8, wherein said image processor is further operable to provide said corrected image data to an image printing device for printing a photograph of said image using said corrected image data.

10. The system of claim 1, wherein said image processor is implemented in an image processing device connected to receive said original image data and said key from said one of said imaging devices and retrieve said image correction data from said centralized database via a data network.

11. The system of claim 10, wherein said image processing device includes a display for displaying said image using said corrected image data.

12. The system of claim 10, wherein said image processing device is included in a computing device.

14. The system of claim 1, wherein said image processor is implemented in an electronic device incorporating said one of said imaging devices, and wherein said electronic device is operable to retrieve said image correction data from said centralized database via a data network.

15. The system of claim 1, further comprising:

an additional processor for receiving at least said original image data from said one of said imaging devices, and wherein said additional processor is operable to automatically transfer said original image data and said key to said image processor.

16. A method for processing images captured by an imaging device, comprising:

providing access to remotely stored image correction data for said imaging device;

receiving original image data representing an image captured said imaging device and a key associated with said imaging device;

retrieving said image correction data for said imaging device using said key; and

processing said original image data using said image correction data for said imaging device to produce corrected image data representing said image.

17. The method of claim 16, wherein said receiving said original image data and said key further comprises:

receiving said original image data and said key at a web server via a data network.

18. The method of claim 17, further comprising:

providing said corrected image data to an image printing device for printing a photograph of said image using said corrected image data.

19. The method of claim 16, wherein said retrieving said corrected image data further comprises:

retrieving said image correction data from a centralized database storing said image correction data via a data network.

20. The method of claim 19, wherein said receiving said original image data and said key further comprises:

automatically transferring said original image data and said key via a data network.

21. A computer-readable medium storing computer-executable instructions operable to implement a method for processing images captured by an image device, said method comprising:

providing access to remotely stored image correction data for said imaging device;
