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 first and second display areas, each display area having pixels of a given size and the pixel size of one display area is different than the pixel size of the other display area comprising:

a) providing a first image to be displayed on the first display area,

b) providing a second image to be display on the second display area wherein the second image is a scaled portion of the first image such that when the images are displayed on the first and second display areas the resulting image appears substantially continuous to a viewer situated to view the image, and

c) transmitting the first image to the first display area and the second image to the second display area.

2. The method of claim 1 wherein the first and second images are provided in a computer readable file.

3. The method of claim 1 wherein the first and second images are provided by a video camera.

6. The method of claim 1 wherein the n images are provided by a video camera.

4. A method for displaying a perceived continuous image across n 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 a first image to be displayed on the first display area,

b) providing n images to be display on the n display areas wherein at least one of the n images is a scaled portion of the first image such that when the images are displayed on the n display areas the resulting image appears substantially continuous to a viewer situated to view the image, and

c) transmitting the n images to the n display areas.

5. The method of claim 4 wherein the n images are provided in a computer readable file.

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

a) capturing a first video image to be displayed on the first display area,

b) capturing a second video image to be display on the second display area wherein the second image is a scaled portion of the first image such that when the images are displayed on the first and second display areas the resulting image appears substantially continuous to a viewer situated to view the image, and

c) transmitting the first video image to the first display area and the second video image to the second display area.
