Abstract

An apparatus and method for controlling a scrolling speed of an apparatus for selecting an image, having steps of providing the image on a viewing device;

dividing the viewing device into a plurality of regions, and assigning an incremental value to each of the plurality of regions, wherein the incremental value is used to calculate the scrolling speed of the apparatus.

Claims

1. A method of controlling a scrolling speed of an apparatus for selecting an image, comprising:

providing the image on a viewing device;

dividing the viewing device into a plurality of regions; and

assigning an incremental value to each of the plurality of regions, wherein the incremental value is used to calculate the scrolling speed of the apparatus.

2. The method according to claim 1, wherein the incremental value comprises at least one pixel increment value.

3. The method according to claim 1, wherein the apparatus comprises at least one of a joystick, mouse, roller ball, touch screen and a directional key for navigating.

4. The method according to claim 1, wherein the image is a volumetric image.

5. The method according to claim 1, wherein the incremental value is user selectable.

6. The method according to claim 1, wherein the plurality of regions are rectangular regions.

7. The method according to claim 1, wherein the plurality of regions are oval in shape.

8. The method according to claim 1, wherein the plurality of regions are circular in shape.

9. The method according to claim 1, further comprising:

indicating a scrolling speed to the user based upon the current incremental value.

10. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for controlling a scrolling speed of an apparatus for selecting an image, comprising:

providing the image on a viewing device;

dividing the viewing device into a plurality of regions; and

assigning an incremental value to each of the plurality of regions, wherein the incremental value is used to calculate the scrolling speed of the apparatus.

11. The program storage device according to claim 10, wherein the incremental value comprises at least one pixel increment value.

12. The program storage device according to claim 10, wherein the apparatus comprises at least one of a joystick, mouse, roller ball, touch screen and a directional key for navigating.

13. The program storage device according to claim 10, wherein the image is a volumetric image.

14. The program storage device according to claim 10, wherein the incremental value is user selectable.

15. The program storage device according to claim 10, wherein the plurality of regions are rectangular regions.

16. The program storage device according to claim 10, wherein the plurality of regions are oval in shape.

17. The program storage device according to claim 10, wherein the plurality of regions are circular in shape.

18. The program storage device according to claim 10, further comprising:

indicating a scrolling speed to the user based upon the current incremental value.
