Abstract:
A method for processing a digital image in a distributed manner to produce a final modified digital image, comprising:a) providing a source digital image at a first computer; b) the first computer responding to the source digital image to produce a base digital image having a dynamic range less than the source digital image and a first difference digital image such that the base digital image and the first difference digital image can be recombined to produce a representation of the source digital image; c) transferring the base digital image and the first difference digital image to a second computer which combines the base digital image and first difference digital image to produce a reconstructed digital image representing the source digital image; d) the second computer modifying the reconstructed digital image to produce a modified digital image and determining a second difference digital image such that the base digital image and the second difference digital image can be recombined to produce the modified digital image; e) transferring the second difference digital image to the first computer; and f) combining in the first computer the second difference digital image with the base digital image to form the final modified digital image.
