Claims
- 1. An image correction system comprising:
an image input device operable to produce a digital image and a defect map, wherein the defect map allows the identification of defective and non-defective regions of the digital image; and a defect correction program having at least one correction routine operable to substantially correct the defective regions of the digital image using the non-defective regions of the digital image to produce an improved digital image.
- 2. The image correction system of claim 1, wherein the at least one correction routine includes a reference line correction routine.
- 3. The image correction system of claim 2, wherein the reference line correction routine includes a feature line.
- 4. The image correction system of claim 2, wherein the reference line correction routine includes a centerline.
- 5. The image correction system of claim 2, wherein the reference line correction routine includes a contour line.
- 6. The image correction system of claim 2, wherein the reference line correction routine includes a user defined reference line.
- 7. The image correction system of claim 1, wherein the at least one defect correction program includes a fill correction routine.
- 8. The image correction system of claim 1, wherein the at least one defect correction program includes an average correction routine.
- 9. The image correction system of claim 1, wherein the at least one defect correction program is incorporated into a user interface of the image input device.
- 10. The image correction system of claim 1, further comprising an output device operable to receive the improved digital image.
- 11. The image correction system of claim 1, wherein the image input device comprises a film scanner.
- 12. The image correction system of claim 1, wherein the image input device comprises a flatbed scanner.
- 13. A defect correction program operable to:
receive a digital image and a corresponding defect map, wherein the defect map identifies at least one defective region of the digital image and a non-defective region of the digital image; and correct the at least one defective region using at least one correction routine.
- 14. The defect correction program of claim 13, wherein the at least one correction routine includes a reference line correction routine.
- 15. The defect correction program of claim 14, wherein the reference line correction routine includes a feature line.
- 16. The defect correction program of claim 14, wherein the reference line correction routine includes a centerline.
- 17. The defect correction program of claim 14, wherein the reference line correction routine includes a contour line.
- 18. The defect correction program of claim 14, wherein the reference line correction routine includes a user defined reference line.
- 19. The defect correction program of claim 13, wherein the at least one defect correction program includes a fill correction routine.
- 20. The defect correction program of claim 13, wherein the at least one defect correction program includes an average correction routine.
- 21. A method for correcting an image, comprising:
determining at least one defective region and an associated non-defective region using a defect map; parsing the at least one defective region into sub-regions using at least one reference line; and filling the sub-regions using data calculated from the non-defective regions associated with the sub-regions.
- 22. The method of claim 21, wherein the at least one reference line comprises a feature line.
- 23. The method of claim 21, wherein the at least one reference line comprises a contour line.
- 24. The method of claim 21, wherein the at least one reference line comprises a user defined reference line.
- 25. The method of claim 21, wherein filling the sub-regions using data calculated from the non-defective regions comprises filling the subregions using data calculated by interpolation from the non-defective regions associated with the sub-regions.
- 26. The method of claim 25, wherein the interpolation comprises a straight-line interpolation.
