Abstract

A method of using two or more display units with different resolutions which have been combined such that the geometry of images displayed across the multiple display units is preserved and the image appears to be substantially continuous to a viewer of the image. Compatibility of the sizes of image elements on different display units is achieved by using display unit-specific scaling to compensate for the different pixel sizes on the individual display units.

Claims

1. A method for displaying a perceived continuous image across at least two display areas, each display area having a given display resolution and the display resolution of at least one display area is different than the display resolution of at least one other display area, the method comprising:

a) providing image information data representing an image,

b) replicating the image information to provide image information data associated with each of the display areas, wherein the image information data associated with each of the display areas is to be displayed on each of the associated display areas, and

c) transforming at least one of the associated image information data such that when the image represented by the image information data is displayed on each of the display areas from the associated image information data, the resulting displayed image on the at least two display areas is continuous within a tolerance value, and the displayed resolution of the image displayed on the at least one display area is different from the displayed resolution of the image displayed on the at least one other display area.

2. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming two of the image information data.

3. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming three of the image information data.

4. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming the image information data such that when the image is displayed from the image information data, the displayed image is scaled in size.

5. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming the image information data such that when the image is displayed from the image information data, the displayed image is clipped.

6. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming the image information data such that when the image is displayed from the image information data, the displayed image is translated.

7. The method of claim 1 wherein the step of transforming at least one of the associated image information data comprises transforming the image information data such that when the image is displayed from the image information data, the displayed image has modified colors.

8. The method of claim 1, wherein the step of transforming at least one of the associated image information data comprises transforming the image information data such that when the image is displayed from the image information data, the displayed image is rotated.

9. The method of claim 1, further comprising receiving user input data before the step of providing image information data, wherein the user input data is used to provide the image information data.

10. The method of claim 1, further comprising sending the image information data to the associated display area.

11. The method of claim 10, further comprising displaying the image on the associated display area from the image information data.

12. A method for displaying a perceived continuous image across first and second display areas, each of the first and second display areas having a given display resolution and the display resolution of the first display area is different than the display resolution of the second display area, the method comprising:

a) providing image information data representing an image,

b) replicating the image information to provide first image information data to be displayed on the first display area and second image information data to be displayed on the second display area, and

c) transforming the first image information data such that when the image represented by the image information data is displayed on the first and second display areas from the associated first and second image information data, the resulting displayed image on the first and second display areas is continuous within a tolerance value, and the displayed resolution of the image displayed on the first display area is different than the displayed resolution of the image displayed on the second display area.

13. The method of claim 12, further comprising transforming the second image information data.

14. The method of claim 12, wherein the step of transforming the first image information data comprises scaling the image information data.

15. The method of claim 12, wherein the step of transforming the first image information data comprises transforming the first image information data such that when the image is displayed from the first image information data, the displayed image is clipped.

16. The method of claim 12, wherein the step of transforming the first image information data comprises transforming the first image information data such that when the image is displayed from the first image information data, the displayed image is translated.

17. The method of claim 12, wherein the step of transforming the first image information data comprises transforming the image information data such that when an image is displayed from the image information data, the displayed image has modified colors.

18. The method of claim 12, wherein the step of transforming the first image information data comprises transforming the first image information data such that when the image is displayed from the first image information data, the displayed image is rotated.

19. The method of claim 12, further comprising receiving user input data before the step of providing image information data wherein the user input data is used to provide the image information data.

20. The method of claim 12, further comprising sending the image information data to the associated display area.

21. The method of claim 12, further comprising displaying the image on the associated display area from the image information data.

22. A method for displaying a perceived continuous image across first and second display areas, each of the first and second display areas having a given display resolution and the display resolution of the first display area is different than the display resolution of the second display area, the method comprising:

a) receiving user input data,

b) providing image information data representing an image determined by the user input data,

c) replicating the image information to provide first image information data to be displayed on the first display area and second image information data to be displayed on the second display area,

d) transforming the first image information data such that when the image represented by the image information data is displayed on each of the first and second display areas from the associated image information data, the resulting displayed image on the first and second display areas is continuous within a tolerance value, and the displayed resolution of the image displayed on the first display area is different from the displayed resolution of the image displayed on the second display area, and

e) displaying the image on each of the associated display areas from the image information data.
