Abstract

A system and method are disclosed, that may include establishing communication between a first computer and a second computer over a communication link, the second computer having an image collection stored therein in the form of compressed image data; selecting a plurality of images in the collection for communication to said first computer; and transmitting low-resolution image data for all of the selected images from the second computer to the first computer before transmitting full-resolution image data for any of the selected images.

Claims

1. A method, comprising:

establishing communication between a first computer and a second computer over a communication link, said second computer having an image collection comprised of at least two images stored therein in the form of compressed image data;

transmitting image data at a first resolution for said image collection to render a montage of the image collection, wherein said montage is a collage of said image collection having a layout of the at least two images that is configured to be rearranged by a user of the first computer;

receiving a selection of a first image from said image collection as rendered in said montage, said selection received for viewing said first image at a higher resolution than said first resolution;

transmitting at least a portion of the compressed image data for said first image from said second computer to said first computer, wherein said transmitting includes downloading, to said first computer, full-resolution image data for a first region of interest of said first image;

wherein said transmitting at least a portion of the compressed image data further comprises;

transmitting at least low-resolution image data for a region of said first image external to said first region of interest, wherein said low-resolution is a lower resolution than said higher resolution; and

wherein said transmitting at least low-resolution image data further comprises;

transmitting said image data for external region, wherein said external-region image data is provided at a resolution that increases with progressively increasing proximity to said first region of interest.

2. The method of claim 1 further comprising:

at least partially reducing a resolution level at which said image data for said first region of interest is stored in said first computer; and

downloading, to said first computer, additional image data for a second region of interest of said first image to enable rendering said second region of interest at full resolution.

3. The method of claim 2 wherein said second region of interest overlaps with said first region of interest.

4. The method of claim 2 wherein said second region of interest does not overlap with said first region of interest.

5. The method of claim 2 further comprising:

repeating said at partially reducing step and said downloading additional image data step to provide a shifting region of interest.

6. The method of claim 1 further comprising:

selecting a plurality of additional images in said image collection;

transmitting at least a portion of the image data for each of said selected images from said second computer to said first computer before transmitting an entirety of any of said selected images from said second computer to said first computer.

7. A method, comprising:

establishing communication between a first computer and a second computer over a communication link, said second computer having an image collection comprised of a plurality of images stored therein in the form of compressed image data;

receiving a selection of images in said collection for communication to said first computer, wherein the selection of images is fewer than the image collection;

transmitting low-resolution image data for all of said selected images as a montage from said second computer to said first computer before transmitting full-resolution image data for any of said selected images collection, the montage having a layout of the selected images that is configured to be rearranged by a user of the first computer;

in response to receiving a user selection for a region of interest from the montage, transmitting full-resolution image data for the region of interest of the montage configured to be rearranged in the montage, the region of interest being less than all of the plurality of images; and

the method further comprises;

transmitting less-than-full resolution image data for the portion of said plurality of images external to said region of interest, wherein said transmitting said less-than-full resolution image data for said external portion of said plurality of images comprises;

transmitting external portion image data such that the resolution at which said external portion of said plurality of images is stored at said first computer increases with progressively increasing proximity to said region of interest.

8. The method of claim 7 wherein said plurality of images are pages of a publication.

9. The method of claim 8 wherein said pages of said publication have a defined sequential order.

10. The method of claim 9 further comprising:

rendering a first selected one of said pages at full resolution, wherein said first selected page is a first active page.

11. The method of claim 10 further comprising:

rendering pages of said plurality of pages other than said first active page at less than full resolution.

12. The method of claim 11 further comprising:

rendering said other pages at a degree of resolution that decreases with an increasing distance in pages from said first active page.

13. The method of claim 12 wherein said other pages are rendered at resolutions equal to said full resolution, at which said first active page is rendered, divided by a constant raised to powers equal to distances in pages by which respective ones of said other pages are located at with respect to said first active page.

14. The method of claim 13 wherein said constant equals two.

15. The method of claim 11 further comprising:

discarding at least a portion of the image data enabling rendering said first active page at said full resolution;

rendering a second selected one of said pages at full resolution, thereby making said second selected page a second active page.

16. The method of claim 15 wherein said second active page either immediately precedes or immediately succeeds said first active page in said sequential order of pages.

17. The method of claim 15 wherein said second active page is at least two pages away from said first active page in said sequential order of pages.

18. The method of claim 7 wherein said second computer is a portable device.

19. The method of claim 18 wherein said first computer is a personal computer.

20. The method of claim 18 wherein said first computer is a web server.

21. The method of claim 7 wherein said communication link comprises a direct link between said first computer and said second computer.

22. The method of claim 7 wherein said communication link comprises an Internet communication link.

23. The method of claim 19 wherein said portable device is a digital camera and said plurality of images are photos.

24. The method of claim 23 further comprising:

completing said transmission of said data for said photos to said personal computer from said digital camera.

25. The method of claim 24 further comprising:

uploading said photos to a web server.

26. The method of claim 24 further comprising:

storing said transmitted data in a virtual display of said personal computer.

27. The method of claim 26 wherein said virtual display includes wavelet data able to at least partially describe said images.

28. The method of claim 26 further comprising:

continuing said transmitting and said storing until said image data in said virtual display is represented at a specified resolution.

29. The method of claim 28 further comprising:

rendering said image data stored in said virtual display at said specified resolution on a physical display.

30. The method of claim 7 further comprising:

providing a cached representation of all images in said image collection in said first computer, wherein said cached representation is stored at lower resolution than said image collection stored in said second computer, said cached representation of said images being cache images within a cache of said first computer.

31. The method of claim 7 further comprising:

rendering said montage to a physical display of said first computer, said physical display displays said montage within a compact region of said physical display.

32. The method of claim 31 wherein said compact region is at least substantially rectangular.

33. The method of claim 31 further comprising:

zooming into and out of said montage.
