Abstract

A system utilizing two or more display units with different resolutions are 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 system 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) an application providing image information data for an image,

b) an image replicator so arranged and constructed to receive the image information data for the application and to replicate the image information to provide image information data associated with each display area, and

c) a viewer associated with each display area, so constructed and arranged to received the image information data from the image replicator, which receives the associated image information data associated with each display area wherein at least one viewer transforms 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 system of claim 1 wherein the first viewer transforms the first image information data and the second viewer transforms the second image information data.

3. ) The system of claim 1 wherein there are three viewers.

4. ) The system of claim 1 wherein the viewer transforms the associated image information data by scaling the image information data.

5. ) The system of claim 1 wherein the viewer transforms the associated image information data such that when an image is displayed from the first image information data, the displayed image is clipped.

6. ) The system of claim 1 wherein the viewer transforms the associated image information data such that when an image is displayed from the first image information data, the displayed image is translated.

7. ) The system of claim 1 wherein the viewer transforms the associated image information data such that when an image is displayed from the first image information data, the displayed image is color transformed.

8. ) The system of claim 1 wherein the viewer transforms the associated image information data such that when an image is displayed from the first image information data, the displayed image is rotated.

9. ) The system of claim 1 further comprises an input collector for receiving user input data wherein the application receives and responds to the user input data to provide image information data.

10. ) The system of claim 1 further comprising display areas associated with and responsive to each viewer for displaying an image on the associated display area from the image information data.

11. ) A system 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) an application providing image information data for an image,

b) an image replicator 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,

c) a first viewer associated with the first display area for receiving first image information data, and

d) a second viewer associated with the second display area for receiving second image information data wherein at least one of the first and second viewers transforms the associated image information data such that when images are displayed on the first and second display areas from the first and second image information data the resulting image on the first and second display areas appears substantially continuous to a viewer situated to view the image.

12. ) The system of claim 11 wherein the first viewer transforms the first image information data and the second viewer transforms the second image information data.

13. ) The system of claim 11 wherein there are three viewers.

14. ) The system of claim 11 wherein the viewer transforms the associated image information data by scaling the image information data.

15. ) The system of claim 11 wherein the transforms the associated image information data by such that when an image is displayed from the first image information data, the displayed image is clipped.

16. ) The system of claim 11 wherein the transforms the associated image information data by such that when an image is displayed from the first image information data, the displayed image is translated.

17. ) The system of claim 11 wherein the transforms the associated image information data by such that when an image is displayed from the first image information data, the displayed image is color transformed.

18. ) The system of claim 11 wherein the transforms the associated image information data by such that when an image is displayed from the first image information data, the displayed image is rotated.

19. ) The system of claim 11 further comprising an input collector for receiving user input data wherein the application receives and responds to the user input data before providing image information data.

20. ) The system of claim 11 further comprising display areas associate with and responsive to each viewer for displaying an image on the associated display area from the image information data.

21. ) A system 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) an input collector for receiving user input data,

b) an application responsive to the user input data providing image information data for an image,

b) an image replicator 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,

c) a first viewer associated with the first display area for receiving first image information data,

d) a second viewer associated with the second display area for receiving second image information data wherein at least one of the first and second viewers transforms the associated image information data such that when images are displayed on the first and second display areas from the first and second image information data the resulting image on the first and second display areas appears substantially continuous to a viewer situated to view the image,

e) a first display area responsive to the first viewer for displaying an image, and

f) a second display area responsive to the second viewer for displaying an image.
