Abstract

There is provided a system and method for selective viewing of a hidden image within a displayed image. There is provided a method for providing a composite presentation, comprising displaying a plurality of elemental presentations including a first presentation and a second presentation to provide the composite presentation, wherein the displaying of the second presentation makes at least a first portion of the first presentation become unrecognizable to a human eye viewing the composite presentation without a use of a visual aid. This rendering of the first presentation as unrecognizable to the human eye may be accomplished through filtering techniques such as one or more of optical polarization, shuttering, depth of field alteration, light intensity alteration, light angle alteration, anaglyph filters, and other filtering techniques.

Claims

2. The method of claim 1, wherein each of the presentations is an image.

3. The method of claim 1, wherein the first presentation is a presentation of a color.

4. The method of claim 1, wherein the first portion of the first presentation becomes recognizable to the human eye viewing the composite presentation with the use of the visual aid.

5. The method of claim 1, the displaying of the second presentation makes the first portion of the first presentation unrecognizable to the human eye by using a filtering technique including at least one of polarization, shuttering, depth of field alteration, light intensity alteration and light angle alteration.

6. The method of claim 1, wherein prior to the displaying, the method further comprising:

pre-processing the first presentation and a third presentation to generate a pre-processed first presentation and a pre-processed third presentation; and

subtracting the pre-processed first presentation from the pre-processed third presentation, pixel-by-pixel, to generate the second presentation, wherein a plurality of pixels have values greater than or equal to zero.

7. The method of claim 6, wherein after the subtracting and prior to the displaying, the method further comprising:

color-balancing the second presentation pixel-by-pixel for adjusting visible color and brightness of the second presentation.

8. The method of claim 7, wherein two or more of the pre-processing, the subtracting and color-balancing are performed simultaneously.

9. The method of claim 1, wherein the composite presentation comprises a pattern indistinguishable to the human eye from a surrounding background.

10. The method of claim 9, wherein the pattern and the surrounding background both comprise a solid white color.

11. The method of claim 1, wherein the plurality of elemental presentations further include a fourth presentation.

12. The method of claim 11, wherein the displaying of the fourth presentation makes a second portion of the first presentation become unrecognizable to the human eye viewing the composite presentation without the use of the visual aid.

13. The method of claim 11, wherein the displaying of the second presentation and the fourth presentation makes the first portion of the first presentation become unrecognizable to the human eye viewing the composite presentation without the use of the visual aid.

14. The method of claim 11, wherein the displaying of the first presentation makes at least a first portion of the fourth presentation become unrecognizable to the human eye viewing the composite presentation without the use of the visual aid.

15. The method of claim 1, wherein one or more of the plurality of elemental presentations are animated images.

16. The method of claim 1, wherein one or more of the plurality of elemental presentations are still images.

17. The method of claim 1, wherein the composite presentation is an animated image.

18. The method of claim 1, wherein the composite presentation is a still image.

19. The method of claim 1, wherein the displaying of the first presentation and the second presentation is performed simultaneously.

20. The method of claim 19, wherein the displaying of the plurality of elemental presentations is performed such that at least a portion of one or more of the plurality of elemental presentations is rendered unrecognizable by an optical polarization and/or anaglyph filter.

21. The method of claim 1, wherein the displaying of the first presentation and the second presentation is performed sequentially for a first time interval and a second time interval, respectively.

22. The method of claim 21, wherein the displaying of the plurality of elemental presentations is performed such that at least a portion of one or more of the plurality of elemental presentation is rendered unrecognizable by a shutter mechanism blocking a transmission of light during the second time interval.

23. The method of claim 1, wherein prior to the displaying, the method further comprising:

polarizing at least a portion of the first presentation in one direction; and

polarizing at least a portion of the second presentation in the other direction.

24. A system for providing a composite presentation, the system comprising:

a display device configured to display a plurality of elemental presentations including a first presentation and a second presentation to provide the composite presentation;

wherein the second presentation makes at least a first portion of the first presentation become unrecognizable to a human eye viewing the composite presentation without a use of a visual aid.

25. The system of claim 24, wherein the first portion of the first presentation becomes recognizable to the human eye viewing the composite presentation with the use of the visual aid.

26. The system of claim 24, the display device is configured to make the first portion of the first presentation unrecognizable to the human eye by using a filtering technique including at least one of polarization, shuttering, depth of field alteration, light intensity alteration and light angle alteration.

27. The system of claim 24, wherein the display device is configured to display the first presentation and the second presentation simultaneously.

28. The system of claim 27, wherein the display device is configured to display the plurality of elemental presentations such that at least a portion of one or more of the plurality of elemental presentations is rendered unrecognizable by an optical polarization and/or anaglyph filter.

29. The system of claim 24, the display device is configured to display the first presentation and the second presentation sequentially for a first time interval and a second time interval, respectively.

30. The system of claim 29, wherein the display device is configured to display the plurality of elemental presentations such that at least a portion of one or more of the plurality of elemental presentation is rendered unrecognizable by a shutter mechanism blocking a transmission of light during the second time interval.

31. The system of claim 24 further comprising:

a polarizer configured to polarize at least a portion of the first presentation in one direction and polarize at least a portion of the second presentation in the other direction, prior to the display device displaying the first presentation and the second presentation.

32. A method of providing a composite image, the method comprising:

displaying a plurality of elemental images including the first image and the second image to show the composite image;

wherein the second image is a result of a combination of the first image with a third image, and wherein the displaying of the first image and the second image to show the composite image is such that the composite image appears as the third image to a human eye viewing the composite presentation without a use of a visual aid.
