Abstract

A method comprising generating a first value in a first image data subset using a portion of image data and a splitting factor, and generating a second value in a second image data subset using the portion of image data and the splitting factor is provided. The first value and the second value are generated to cause image information corresponding to the portion of image data to be reproduced in response to being simultaneously displayed with first and second projection devices, respectively.

Claims

1. A method comprising:

generating a first value in a first image data subset using a first portion of image data and a first splitting factor; and

generating a second value in a second image data subset using the first portion of image data and the first splitting factor;

wherein the first value and the second value are generated to cause first image information corresponding to the first portion of image data to be reproduced in response to being simultaneously displayed with first and second projection devices, respectively.

2. The method of claim 1 wherein the first value comprises a first portion of the first portion of image data, and wherein the second value comprises a second portion of the first portion of image data.

3. The method of claim 1 wherein the first value and the second value are generated to cause the first image information to be reproduced at a first intensity by the first and the second projection devices that is greater than a second intensity of a reproduction of the first image information by only one of the first and the second projection devices.

4. The method of claim 1 further comprising:

generating a third value in the first image data subset using a second portion of image data and a second splitting factor; and

generating a fourth value in the second image data subset using the second portion of image data and the second splitting factor;

wherein the third value and the fourth value are generated to cause second image information corresponding to the second portion of image data to be reproduced in response to being simultaneously displayed with first and second projection devices, respectively.

5. The method of claim 4 wherein the first portion of image data comprises a first pixel value, and wherein the second portion of image data comprises a second pixel value.

6. The method of claim 4 wherein the first portion of image data comprises a first frame, and wherein the second portion of image data comprises a second frame.

7. The method of claim 4 wherein the first portion of image data comprises a first color plane, and wherein the second portion of image data comprises a second color plane.

8. The method of claim 1 further comprising:

generating a third value in a third image data subset using the first portion of image data and the first splitting factor;

wherein the first value, the second value, and the third value are generated to cause the first image information corresponding to the first portion of image data to be reproduced in response to being simultaneously displayed with the first projection device, the second projection device, and a third projection device, respectively.

9. A system comprising:

a first splitting unit configured to generate a first image data subset using image data and at least a first splitting factor; and

a second splitting unit configured to generate a second image data subset using the image data and at least the first splitting factor;

wherein the first image data subset and the second image data subset are generated to cause an image corresponding to the image data to be reproduced in response to being simultaneously displayed with first and second projection devices, respectively.

10. The system of claim 9 wherein the first image data subset includes a first value that comprises a first portion of a second value of the image data, and wherein the second image data subset includes a third value that comprises a second portion of the second value of the image data.

11. The system of claim 9 wherein the first image data subset and the second image data subset are generated to cause the image to be reproduced at a first intensity by the first and the second projection devices that is greater than a second intensity of a reproduction of the first image information by only one of the first and the second projection devices.

12. The system of claim 9 wherein the first splitting unit is configured to generate a first portion of the first image data subset using the image data and the first splitting factor, wherein the first splitting unit is configured to generate a second portion of the first image data subset using the image data and a second splitting factor, wherein the second splitting unit is configured to generate a first portion of the second image data subset using the image data and the first splitting factor, and wherein the second splitting unit is configured to generate a second portion of the second image data subset using the image data and the second splitting factor.

13. The system of claim 12 wherein the first portion of the first image data subset corresponds to a first plurality of pixels of the image data, wherein the second portion of the first image data subset corresponds to a second plurality of pixels of the image data, wherein the first portion of the second image data subset corresponds to the first plurality of pixels of the image data, and wherein the second portion of the second image data subset corresponds to the second plurality of pixels of the image data.

14. The system of claim 12 wherein the first portion of the first image data subset corresponds to a first frame of the image data, wherein the second portion of the first image data subset corresponds to a second frame of the image data, wherein the first portion of the second image data subset corresponds to the first frame of the image data, and wherein the second portion of the second image data subset corresponds to the second frame of the image data.

15. The system of claim 12 wherein the first portion of the first image data subset corresponds to a first color plane of the image data, wherein the second portion of the first image data subset corresponds to a second color plane of the image data, wherein the first portion of the second image data subset corresponds to the first color plane of the image data, and wherein the second portion of the second image data subset corresponds to the second color plane of the image data.

16. The system of claim 12 further comprising:

a factor unit configured to provide the first splitting factor and the second splitting factor to the first splitting unit and the second splitting unit.

17. A system for displaying an image, the system comprising:

a sub-frame generation system; and

first and second projection devices;

wherein the sub-frame generation system is configured to define a first sub-frame using a first image data subset that is generated from image data using at least a first splitting factor, wherein the sub-frame generation system is configured to define a second sub-frame using a second image data subset that is generated from the image data using at least the first splitting factor, and wherein the first and the second projection devices are adapted to project the first and the second sub-frames onto a display surface such that the second sub-frame at least partially overlaps the first sub-frame.

18. The system of claim 17 wherein the first image data subset is generated from the image data by applying the first splitting factor to a first frame of the image data and by applying a second splitting factor to a second frame of the image data, and wherein the second image data subset is generated from the image data by applying the first splitting factor to the first frame of the image data and by applying the second splitting factor to the second frame of the image data.

19. The system of claim 17 wherein the first image data subset is generated from the image data by applying the first splitting factor to a first color plane of the image data and by applying a second splitting factor to a second color plane of the image data, and wherein the second image data subset is generated from the image data by applying the first splitting factor to the first color plane of the image data and by applying the second splitting factor to the second color plane of the image data.

20. The system of claim 17 wherein the first sub-frame is generated based on maximization of a probability that a first simulated image is the same as at least the first subset of image data, and wherein the second sub-frame is generated based on maximization of a probability that a second simulated image is the same as at least the second subset of image data.
