Abstract

An image processing system includes a client device including a limited display having a resolution less than VGA and a bit depth less than 24 bits for displaying a low resolution digital image and image processing operation indicators, an operator interface for user input, a CPU and a memory, the CPU being capable of running a limited client image processing program, and a first communication port; an image processing server for performing an image processing operation on a high definition image stored at the image processing server, for producing a low resolution version of the image for display on the limited display of the client device, and for producing image processing operation indicators indicating a particular image processing operation, the image processing server including a second communication port and being responsive to remote user inputs to produce a processed digital image; and a limited bandwidth mobile communication network connectable with the first and second communication ports for transmitting the low resolution image and the image processing operation indicators from the image processing server to the client device and transmitting remote user inputs from the client device to the image processing server.

(b) an image processing server for performing an image processing operation on a high definition image stored at the image processing server, for producing a low resolution version of the image for display on the limited display of the client device, and for producing image processing operation indicators indicating a particular image processing operation, the image processing server including a second communication port and being responsive to remote user inputs to produce a processed digital image; and

(c) a limited bandwidth mobile communication network connectable with the first and second communication ports for transmitting the low resolution image and the image processing operation indicators from the image processing server to the client device and transmitting remote user inputs from the client device to the image processing server.

2. The system claimed in claim 1, wherein the limited bandwidth mobile communication network is a commercial wireless network used by cellular telephones.

3. The system claimed in claim 2, wherein the wireless communication network includes the Internet.

4. The system claimed in claim 1, wherein the image processing server further comprises a digital image storage unit and a database management unit.

5. The system claimed in claim 1, wherein the image processing server further comprises a user input processing unit responsive to the remote user inputs for controlling the host image processing application.

6. The system claimed in claim 1, wherein the image processing server includes an image processing unit for performing the image processing operation and an image rendering unit for generating the low resolution version of the image.

7. The system claimed in claim 1, wherein the operator interface of the client device comprises a touch-screen.

8. The system claimed in claim 1, wherein the operator interface of the client device comprises microphone and a speech recognition unit.

9. The system claimed in claim 1, wherein the operator interface of the client device comprises a keypad with buttons.

10. The system claimed in claim 1, wherein the client device comprises a digital camera and a docking station.

11. The system claimed in claim 1, wherein the client device comprises a cellular telephone.

12. The system claimed in claim 11, wherein the cellular telephone further comprises a low resolution digital camera.

13. The system claimed in claim 1, wherein the client device comprises a PDA.

14. The system claimed in claim 13, wherein the PDA further comprises a digital camera.

15. The system claimed in claim 1, wherein the client device comprises a hybrid cell phone/PDA.

16. The system claimed in claim 1, wherein the image processing server performs the image processing operation prior to a remote user input and sends the low resolution image and image processing operation indicators to the client device.

17. The system claimed in claim 1, wherein the image processing server sends the low resolution image to the client device prior to image processing and wherein the operator interface of the client device includes a menu of image processing operations.

18. The system claimed in claim 1, wherein the resolution of the display of the client device is insufficient for displaying the effect of the image processing operation.

19. The system claimed in claim 18, wherein the image processing operation is red eye reduction and the image processing operation indicators include an indication that redeye reduction was performed.

20. The system claimed in claim 19, wherein the image processing server is responsive to a user input to provide an indication of the location in the image where the redeye reduction was performed.

21. The system claimed in claim 20, wherein the indication of the location is provided by sending an enlarged portion of the image where redeye reduction was performed, with a graphic element in the image indicating the location of redeye reduction.

22. The system claimed in claim 18, wherein the image processing operation is redeye reduction that is performed in response to an initial user input requesting that redeye reduction be performed.

23. The system claimed in claim 22, wherein the user input includes an indication of the region of the image where the redeye reduction is to be performed.
