Abstract

One form of the present invention provides a method of displaying multiple image streams that includes providing a first plurality of image streams, processing the plurality of image streams, thereby generating at least one processed image stream, and projecting the at least one processed image stream onto a non-planar surface with at least one projector, thereby generating a plurality of different projected image streams at a corresponding plurality of different positions on the non-planar surface.

Claims

1. A method of displaying multiple image streams, the method comprising:

providing a first plurality of image streams;

processing the plurality of image streams, thereby generating at least one processed image stream;

projecting the at least one processed image stream onto a non-planar surface with at least one projector, thereby generating a plurality of different projected image streams at a corresponding plurality of different positions on the non-planar surface; and

wherein the at least one processed image stream is configured to cause movement of at least one of the projected image streams across the non-planar surface without movement of the at least one projector.

2. The method of claim 1, wherein the non-planar surface is a non-planar developable surface.

3. The method of claim 1, wherein the projected image streams are positioned on the non-planar surface in a non-overlapping or substantially non-overlapping arrangement, wherein each image stream in the first plurality includes different image content than the other image streams, and wherein each of the projected image streams corresponds to one of the image streams in the first plurality of image streams.

4. The method of claim 1, and further comprising:

receiving selection information from a user identifying one of the projected image streams.

5. The method of claim 1, and further comprising:

receiving stream modification information; and

modifying at least one property of at least one of the projected image streams in response to receiving the stream modification information.

6. The method of claim 1, wherein the processing of the plurality of image streams comprises geometric processing and photometric processing.

7. The method of claim 1, wherein the at least one projector includes a plurality of projectors positioned in a tiled arrangement.

8. The method of claim 4, and further comprising:

automatically moving the identified projected image stream to a different position on the non-planar surface without movement of the at least one projector in response to receiving the selection information.

9. The method of claim 4, and further comprising:

automatically moving all of the projected image streams to different positions on the non-planar surface without movement of the at least one projector in response to receiving the selection information.

10. The method of claim 4, and further comprising:

automatically changing a size of at least one of the projected image streams in response to receiving the selection information.

11. The method of claim 5, wherein the at least one property is a display position or display size of the at least one projected image stream.

12. The method of claim 5, wherein the modification of at least one property comprises an audio transformation of at least one audio stream associated with the at least one projected stream.

13. The method of claim 5, wherein the modification of at least one property comprises at least one of a 3D transformation, a blending change, a brightness change, and a color change.

14. The method of claim 7, wherein a quantity of projectors in the plurality of projectors is less than a quantity of projected image streams in the plurality of projected image streams.

15. A system for displaying images, comprising:

at least one processing unit configured to process a received plurality of video streams, thereby generating at least one processed video stream;

at least one projector for projecting the at least one processed video stream onto a non-planar display surface, thereby generating a plurality of different projected video streams at a corresponding plurality of different positions on the non-planar display surface; and

wherein the at least one processing unit is configured to cause movement of at least one of the projected video streams across the non-planar display surface without movement of the at least one projector.

16. The system of claim 15, wherein the display surface is a non-planar developable surface.

17. The system of claim 15, wherein the processing unit is configured to cause repositioning and rescaling of at least one of the projected video streams in response to selection information identifying one of the projected video streams.

18. The system of claim 15, wherein the at least one projector includes a plurality of projectors positioned in a tiled arrangement.

19. The system of claim 18, wherein a quantity of projectors in the plurality of projectors is less than a quantity of projected video streams in the plurality of projected video streams.

20. A method of generating a stream for projection onto a non-planar surface, the method comprising:

receiving a plurality of different video streams;

processing the plurality of video streams, thereby generating at least one processed video stream, wherein the at least one processed video stream is configured to produce a plurality of different projected video streams at a corresponding plurality of different positions on the non-planar surface when projected; and

modifying the at least one processed video stream in response to stream modification information such that projection of the modified at least one processed video stream causes movement of at least one of the projected video streams across the non-planar surface without movement of a projector.
