Abstract

A method for selectively accessing a projected image is provided. In one embodiment, the method may include requesting an image display device to transmit over a network a projected image as displayed by the image display device. The method further may include receiving a copy of the requested projected image from the image display device in response to the request over the network.

Claims

1. A method for selectively accessing a projected image, the method comprising:

requesting an image display device to transmit over a network a projected image as displayed by the image display device; and

receiving a copy of the requested projected image from the image display device in response to the request over the network.

2. The method of claim 1, wherein requesting an image display device to transmit a projected image includes wirelessly sending a request for a projected image, where the requested projected image is projected by an image display device.

3. The method of claim 1, wherein after requesting a projected image, receiving a response to the request from the image display device.

4. The method of claim 3, wherein the response includes a message that the projected image is available.

5. The method of claim 1, wherein requesting a projected image includes requesting a plurality of images and receiving a copy of the requested projected image includes receiving a plurality of requested projected images.

6. The method of claim 1, further comprising displaying the requested projected image as received from the image display device.

7. The method of claim 1, wherein requesting a projected image includes providing identity information to the image display device.

8. The method of claim 1, wherein requesting a projected image includes providing network address information to the image display device.

9. The method of claim 1, wherein receiving a copy of the projected image is substantially concurrent with requesting the projected image.

10. A method for image capture between an image display device and a requesting device, the method comprising:

receiving a request from the requesting device for a projected image, where the requested projected image is projected by the image display device;

preparing the projected image for transmission to the requesting device; and

transmitting the projected image to the requesting device.

11. The method of claim 10, further comprising identifying a network address for the requesting device.

12. The method of claim 10, further comprising responding to the request for the projected image.

13. The method of claim 12, wherein responding to the request includes confirming that the request is authorized.

14. The method of claim 10, wherein preparing the projected image for transmission to the requesting device includes formatting the projected image in a select format.

15. The method of claim 14, wherein the select format is a compressed format.

16. The method of claim 14, wherein the select format is a locked format.

17. The method of claim 10, wherein preparing the projected image for transmission to the requesting device includes transferring the projected image to an output buffer.

18. The method of claim 10, wherein transmitting the projected image to the requesting device occurs automatically after preparing the projected image for transmission.

19. The method of claim 10, wherein transmitting the projected image to the requesting device occurs without user input.

20. An image processing and display system comprising:

a network;

an image display device coupled to the network, the image display device configured to project an image; and

a requesting device coupled to the network, the requesting device configured to capture a select image as projected by the image display device.

21. The image processing and display system of claim 20, wherein the requesting device is configured to send a request for the select image.

22. The image processing and display system of claim 21, wherein the image display device is configured to receive and process the request for the select image.

23. The image processing and display system of claim 22, wherein the image display device is configured to transmit a response to the requesting device regarding the request for the select image.

24. The image processing and display system of claim 22, wherein the image display device is configured to transmit the select image to the requesting device.

25. An apparatus for displaying images, the apparatus comprising:

a processor configured to generate an image for display;

memory linked to the processor to store the image; and

optical components configured to display the image;

wherein the processor is further configured to receive a request from a networked requesting device for the image and package and transmit the image to the requesting device.

26. The apparatus of claim 25, wherein the processor is further configured to identify and the memory is configured to store the network address of the requesting device.

27. The apparatus of claim 25, wherein the processor is further configured to identify whether the request from the requesting device is an authorized request.

28. The apparatus of claim 25, wherein the processor is configured to package the image in a compressed format.

29. A program storage device readable by a machine, the storage device tangibly embodying a program of instructions executable by the machine to perform a method for image capture, the method comprising:

receiving a request for transmission of a projected image;

directing preparation of the requested projected image for transmission from an image display device to a requesting device; and

directing transmission of the requested projected image from the image display device to the requesting device.

30. The method of claim 29, further comprising providing a user interface on a network that is configured to enable a user to request transmission of a projected image from an image display device to a requesting device.

31. The method of claim 30, further comprising providing a user interface on a network that is configured to enable a user to define parameters for the request for the projected image.

32. The method of claim 29, further comprising identifying the requesting device that sent the request for the projected image;

33. The method of claim 29, further identifying whether the request is a valid request.

34. A projection system, configured for image capture, the projection system comprising:

an image display device on a network;

a requesting device on the network;

a means for requesting a projected image from the image display device; and

a means for transmitting the projected image to the requesting device.

35. The projection system of claim 34, wherein the means for requesting a projected image includes identifying a select image and sending a request for the select image.

36. The projection system of claim 34, wherein the means for transmitting the projected image includes identifying a network address of the receiving device and transmitting the requested image to the identified network address.

37. The projection system of claim 34, wherein the means for transmitting the projected image includes preparing the projected image in a select format for transmission.
