Abstract

A method for processing an extended color gamut digital image so as to represent the extended color gamut digital image in a storage color space having a limited color gamut digital image and for paying for such processed digital image including a user sending or authorizing the sending of an extended color gamut digital image to a processing site where the extended color gamut digital image is to be processed. Processing such extended color gamut digital image at the processing site can be accomplished by adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image, and representing the limited color gamut digital image in the storage color space. Further, by determining one of more residual images representing differences between the extended color gamut digital image and the limited color gamut digital image, and associating the one of or more residual image(s) with the limited color gamut digital image in the storage color space such that the associated residual image(s) and the limited color gamut digital image are adapted to be used to form a reconstructed extended color gamut digital image. The method also includes the user making payment, and making the processed extended color gamut digital image available to the user via a communications network.

Claims

1. A method for processing an extended color gamut digital image so as to represent the extended color gamut digital image in a storage color space having a limited color gamut digital image and for paying for such processed digital image, comprising the steps of:

a) a user sending or authorizing the sending of an extended color gamut digital image to a processing site where the extended color gamut digital image is to be processed;

b) processing such extended color gamut digital image at the processing site by;

i) adjusting the color values of the extended color gamut digital image to fit within the limited color gamut to form a limited color gamut digital image;

ii) representing the limited color gamut digital image in the storage color space;

iii) determining one of more residual images representing differences between the extended color gamut digital image and the limited color gamut digital image; and

iv) associating the one of or more residual image(s) with the limited color gamut digital image in the storage color space such that the associated residual image(s) and the limited color gamut digital image are adapted to be used to form a reconstructed extended color gamut digital image;

c) the user making payment; and

d) making the processed extended color gamut digital image available to the user via a communications network.

2. The method of claim 1 where step c) includes obtaining a payment identifier from the user.

3. The method of claim 2 where the payment identifier includes information about an account from which payment is to be electronically transferred.

4. The method of claim 2 where the payment identifier includes a credit card account where the payment is to be debited.

5. The method of claim 4 further including the step of providing a reader for reading a credit card from the user.

6. The method of claim 2 where the payment identifier is obtained from the user via a communications network.

7. The method of claim 1 where step d) includes sending the processed extended color gamut digital image to a location designated by the user via the communications network.

8. The method of claim 1 where step d) includes storing the processed extended color gamut digital image on a network server that the user can access via the communications network.

9. The method of claim 1 further including the step of using one or more of the residual image(s) together with the limited color gamut digital image to form a reconstructed extended color gamut digital image.

10. The method of claim 1 further including the step of applying a desirable image modification to the processed extended color gamut digital image.

11. The method of claim 1 where the storage color space is a video RGB color space.

12. The method of claim 11 further including the step of previewing the digital image by displaying the limited color gamut digital image in the storage color space on a video display.

13. The method of claim 1 where the extended color gamut digital image is a representation of the colors in an original scene.

14. The method of claim 13 where the limited color gamut digital image is determined by rendering the colors of the original scene to produce rendered color values that are desirable for a particular output device.

15. The method of claim 1 where the extended color gamut digital image has a larger luminance dynamic range than the limited color gamut digital image.

16. The method of claim 15 where the step of adjusting the color values of the extended color gamut digital image to determine the limited color gamut digital image includes applying a tone scale function to reduce the luminance dynamic range of the image.

17. The method of claim 10 where the desirable image modification is interactively user specified.

18. The method of claim 10 where the desirable image modification is determined by applying an automatic algorithm to the digital image.

19. The method of claim 10 where the desirable image modification includes applying modified color reproduction aims to the image.

20. The method of claim 10 where additional payment is made in order to apply the desirable image modification.

21. A computer storage product having at least one computer storage medium having instructions stored therein causing one or more computers to perform the method of claim 1.
