Abstract

A system for displaying 3-dimensional images is provided. The system comprises a monitor, a rendering module arranged to provide image data for display by the monitor, a point-of-view module for determining the position of a viewer relative to the monitor, wherein the output of said rendering module is dependent on the determined position of the viewer relative to the monitor and a polar correction module arranged to adjust the brightness of one or more pixels of the monitor dependent on the position of the viewer relative to the monitor.

Claims

1. A system including:

a monitor;

a rendering module arranged to provide image data to be displayed by the monitor;

a point-of-view module arranged to determine the position of a viewer relative to the monitor;

wherein the output of the rendering module is dependent on the determined position of the viewer relative to the monitor; and

a polar correction module arranged to adjust the brightness of one or more pixels of the image to be displayed dependent on the determined position of the viewer.

2. A system, as claimed in claim 1, wherein the intensity variation between pixels is determined by the angle of the viewer relative to the monitor and the brightness of one or more pixels are adjusted to provide a corrected image for display on the monitor.

3. A system, as claimed in claim 1 or claim 2, wherein the intensity variation between pixels can be adjusted by increasing and/or decreasing the brightness of one or more pixels.

5. A system, as claimed in claim 1, wherein the point-of-view module is arranged to determine the position of one or more objects associated with the viewer, thereby determining the position of the viewer.

6. A system, as claimed in claim 1, wherein the point-of-view module is arranged to use recent data to define a area to for the viewer.

7. A system, as claimed in claim 1, further including one or more imaging devices arranged to take images of the viewer, wherein the point-of-view module is arranged to determine the position of the viewer from the images of the viewer taken by the imaging devices.

8. A system, as claimed in claim 7, wherein at least one of the one or more imaging device is movable.

4. (canceled)

9. A method of displaying an image of an object on a monitor, the method comprising the steps of:

determining a position of a viewer in a common co-ordinate system;

determining the position of the object in the common co-ordinate system; and

using a rendering module to provide data for displaying the object on the monitor so that, when displayed, the object appears to the viewer as it would when viewed from the determined position of the viewer and wherein the brightness of the output of the rendering module as displayed on one or more pixels of the monitor is dependent on the determined position of the viewer relative to the monitor.

10. A method, as claimed in claim 9, wherein the step of determining the position of the viewer further includes the step of translating the position of the viewer relative to the monitor into the position of the viewer in the common co-ordinate system.

11. A method, as claimed in claim 9, wherein the step of determining the position of the viewer includes the step of determining the position of one or more objects associated with said viewer.

12. A system including:

a monitor arranged to display an image;

a point-of-view module arranged to determine the position of a viewer relative to the monitor; and

a polar correction module arranged to adjust the brightness of one or more pixels of the image to be displayed dependent on the position of the viewer.

13. A method of displaying an image of an object on a monitor, the method including the steps of:

determining a position of a viewer relative to the monitor; and

adjusting the brightness of one or more pixels of the image dependent on the determined position of the viewer relative to the monitor, thereby providing a polar brightness corrected image.
