Abstract

The present invention provides system for capturing displayed digital images. The system includes a selection tool utilisable by a user to select at least one portion of at least one displayed image; and, a capture routine arranged to reproduce the selected portion. If the selection tool selects only a portion of one image, then the captured image is sourced from a secondary storage source and if the selection tool selects more than one portion of one image, then the captured image is sourced from a primary storage source.

Claims

1. A system for capturing displayed digital images comprising:

a selection tool utilisable by a user to select at least one portion of at least one displayed image; and

a capture routine arranged to reproduce the selected portion, wherein if the selection tool selects only a portion of one image, then the captured image is sourced from a secondary storage source and if the selection tool selects more than one portion of one image, then the captured image is sourced from a primary storage source.

2. A system according to claim 1, wherein the selection tool is a frame arranged to define a selection area.

3. A system according to claim 1, wherein the user defined selection tool is resizable.

4. A system according to claim 1, wherein the selection tool is rotatable.

5. A system according to claim 1, wherein the capture routine provides feedback to the user.

6. A system according to claim 5, wherein the feedback is in the form of a visual animation.

7. A system according to claim 5, wherein the feedback is in the form of an audio signal.

8. A system according to claim 1, wherein the primary storage is a frame buffer memory.

9. A system according to claim 1, wherein the secondary storage is a hard disk.

10. A system according to claim 1, wherein the capture routine is arranged to execute on a plurality of threads.

11. A system according to claim 1, wherein the captured image is further processed by changing the size or orientation of a viewport relating to the image.

12. A system according to claim 1, wherein the captured image is rendered by anisotropic texture filtering.

25. A system for capturing digital images comprising a computer unit, the computer unit implementing a system according to claim 1.

26. A computer program comprising at least one instruction for controlling a computer system to implement a method according to claim 1.

28. A computer readable medium providing a computer program in accordance with claims 26.

13. A method for capturing displayed digital images comprising:

utilising a selection tool to select at least one portion of at least one image; and

initiating a capture routine arranged to reproduce the selected portion, wherein if the selection tool selects only a portion of one image, then the captured image is sourced from a secondary storage source and if the selection tool selects more than one portion of one image, then the captured image is sourced from a primary storage source.

14. A method according to claim 13, wherein the selection tool is a frame arranged to define a selection area.

15. A method according to claim 13, wherein the user defined selection tool is resizable.

16. A method according to claim 13, wherein the selection tool is rotatable.

17. A method according to claim 13, wherein the capture routine provides feedback to the user.

18. A method according to claim 17, wherein the feedback is in the form of a visual animation.

19. A method according to claim 17, wherein the feedback is in the form of an audio signal.

20. A method according to claim 13, wherein the primary storage is a frame buffer memory.

21. A method according to claim 13, wherein the secondary storage is a hard disk.

22. A method according to claim 13, wherein the capture routine is arranged to execute on a plurality of threads.

23. A method according to claim 13, wherein the captured image is further processed by changing the size or orientation of a viewport relating to the image.

24. A method according to claim 13, wherein the captured image can be rendered by anisotropic filtering.

27. A computer program comprising at least one instruction for controlling a computer system to implement a method according to claim 13.
