Abstract

The present invention describes a display system. The display system includes a display, the display including a display screen capable of operating in a transparent mode; a lighting characteristic assessment component for determining the lighting characteristics of the content on the display screen and the lighting characteristics behind the display screen; and an adaptive lighting control component for controlling of an at least one lighting source and the lighting characteristics of the content on the display screen, wherein based on a comparison of the lighting characteristics of the content on the display screen and the lighting characteristics behind the display screen, modifying at least one of the lighting characteristics of the content on the display screen or the lighting characteristics of the at least one lighting source.

Claims

1. The display system comprised of:

a display, the display including a display screen for operating in at least a transparent mode;

a lighting characteristic assessment component for determining the lighting characteristics of the content on the display screen and the lighting characteristics behind the display screen; and

an adaptive lighting control component for controlling an at least one lighting source and the lighting characteristics of the content on the display screen, wherein responsive to a comparison of the lighting characteristics of the content on the display screen and the lighting characteristics behind the display screen, modifying at least one of the lighting characteristics of the content on the display screen or the lighting characteristics of the at least one lighting source.

2. The display system recited in claim 1 wherein the at least one lighting source is modified to match the lighting characteristics behind the display screen with the lighting characteristics of the contents on the display screen.

3. The display system recited in claim 1 wherein the lighting characteristics behind the display screen are known and a description of the known lighting characteristics is input to the lighting characteristic assessment component.

4. The display system recited in claim 3 wherein the lighting characteristics of the content on the display screen are modified to match the know lighting characteristics behind the display screen.

5. The display system recited in claim 1 further including a viewpoint assessment component capable of determining a viewpoint of a user positioned in front the display screen;

an object tracking component capable of tracking the user manipulation of an object positioned behind the display screen; and

a display generation component, wherein based on data from the viewpoint assessment component and the object tracking component, the display generation component creates content for display on the display screen.

6. The display system recited in claim 1 further including at least one lighting characteristic sensor for measuring the lighting characteristics behind the display screen.

7. The display system recited in claim 6 wherein the at least one lighting characteristic sensor is an image capture device.

8. The display system recited in claim 1 wherein the at least one lighting source is an LED.

9. The display system recited in claim 1 wherein the at least one lighting source is a picoprojector.

10. A computer readable storage medium having computer readable program instructions stored thereon for causing a computer system to perform instructions, the instructions comprising the steps of:

Determining the lighting characteristics of the content displayed on a display screen;

Determining the lighting characteristics behind a display screen;

Comparing the lighting characteristics of the content displayed on the display screen to the lighting characteristics of a region behind the display screen, responsive the result of the comparison of the lighting characteristics of the content on the display screen and the lighting characteristics of a region behind the display screen, modifying the at least one lighting source or the content on the display screen.

11. The computer readable storage medium recited in claim 10, wherein the lighting characteristics compared include at least the lighting direction and lighting color.

12. The computer readable storage medium recited in claim 11, wherein the lighting characteristics compared further includes the lighting intensity.

13. The computer readable storage medium recited in claim 10 further including the step of modifying the at least one lighting source to match the lighting characteristics behind the display screen with the lighting characteristics of the contents on the display screen.

14. The computer readable storage medium recited in claim 10 further including the step of inputting a description of the known lighting characteristics to the lighting control component when the lighting characteristics behind the display screen are known.

15. The computer readable storage medium recited in claim 10 further including the steps of:

determining a viewpoint of a user positioned in front of the display screen; and

tracking the user manipulation of an object positioned behind the display screen.

16. The computer readable storage medium recited in claim 15 further including the step of generating display content based on data from the viewpoint assessment component and the object tracking component.

17. A method of modifying lighting in a display system comprising the steps of:

Determining the lighting characteristics of the content displayed on a display screen;

Determining the lighting characteristics behind a display screen;

Comparing the lighting characteristics of the content displayed on the display screen to the lighting characteristics of a region behind the display screen, responsive the result of the comparison of the lighting characteristics of the content on the display screen and the lighting characteristics of a region behind the display screen, modifying the at least one of lighting source or the content on the display screen.

18. The method recited in claim 17, wherein the lighting characteristics compared include at least the lighting direction and lighting color.

19. The method recited in claim 17 further including the step of modifying the at least one lighting source to match the lighting characteristics behind the display screen with the lighting characteristics of the contents on the display screen.

20. The method recited in claim 17 further including the step of inputting a description of the known lighting characteristics to the lighting control component when the lighting characteristics behind the display screen are known.
