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 pixels of a given size and the pixel size of at least one display area is different than the pixel size of at least one other display area comprising:

a) providing image information data for an image,

b) replicating the image information to provide image information data associated with each display area, and

c) transforming at least one of the associated image information data such that when images are displayed on each display area from the associated image information data the resulting image on at least two display areas appears substantially continuous to a viewer situated to view the image.

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 an 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 an 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 an 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 an 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 an 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 an image on the associated display area from the image information data.

13. The method of claim 12 wherein the step of transforming the first image information data further comprises 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 an 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 an 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 1 wherein the step of transforming the first image information data comprises transforming the first image information data such that when an 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 an 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 display area having pixels of a given size and the pixel size of at one display area is different than the pixel size of the other display area comprising:

a) providing image information data for an image,

b) replicating the image information to provide first image information data associated with the first display area and second image information data associated with the second display area, and

c) transforming first image information data such that when images are displayed on each display area from the associated image information data the resulting image on the two display areas appears substantially continuous to a viewer situated to view the image.

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

a) receiving user input data,

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

c) replicating the image information to provide first image information data associated with the first display area and second image information data associated with the second display area,

d) transforming first image information data such that when images are displayed on each display area from the associated image information data the resulting image on the two display areas appears substantially continuous to a viewer situated to view the image, and

e) displaying an image on the associated display area from the image information data.
