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

1. A method of providing a composite presentation, the method comprising:

receiving a first presentation and a second presentation in a plurality of presentations, wherein each of the first presentation and the second presentation comprises one or more images that are human-perceptible;

subtracting the first presentation from the second presentation on a pixel-by-pixel basis to obtain a difference presentation, wherein the difference presentation does not present any human-perceptible images; and

displaying, via a processor, the first presentation and the difference presentation to reproduce the composite presentation, wherein the composite presentation is human-perceptible as the second presentation;

wherein at least a first portion of the first presentation is selectively revealed to a viewer when viewing the composite presentation via a visual aid.

2. The method of claim 1, wherein the first presentation comprises a presentation of a color.

3. The method of claim 1, wherein the displaying of the difference presentation renders the first portion of the first presentation imperceptible to the human eye by employing a filtering technique including at least one of polarization, shuttering, depth of field alteration, light intensity alteration and light angle alteration.

4. The method of claim 1, wherein prior to the displaying, the method further comprises:

pre-processing the first presentation and a third presentation in the plurality of presentations 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, on a pixel-by-pixel basis, to generate the difference presentation, wherein a plurality of pixels have values greater than or equal to zero.

5. The method of claim 4, wherein after the subtracting and prior to the displaying, the method further comprises:

color-balancing the difference presentation on a pixel-by-pixel basis for adjusting visible color and brightness of the difference presentation.

6. The method of claim 5, wherein two or more of the pre-processing, the subtracting and color-balancing are performed simultaneously.

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

8. The method of claim 7, wherein the pattern and the surrounding background both comprise a solid white color.

9. The method of claim 1, further comprising a third presentation in the plurality of presentations.

10. The method of claim 9, further comprising displaying the third presentation renders a second portion of the first presentation imperceptible to the human eye viewing the composite presentation without the visual aid.

11. The method of claim 9, wherein the displaying of the difference presentation and the third presentation renders the first portion of the first presentation become imperceptible to the human eye viewing the composite presentation without the visual aid.

12. The method of claim 9, wherein the displaying of the first presentation renders at least a first portion of the third presentation become imperceptible to the human eye viewing the composite presentation without the visual aid.

13. The method of claim 1, wherein one or more of the presentations in the plurality of presentations comprise animated images.

14. The method of claim 1, wherein one or more of the presentations in the plurality of presentations comprise still images.

15. The method of claim 1, wherein the composite presentation comprises an animated image.

16. The method of claim 1, wherein the composite presentation comprises a still image.

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

18. The method of claim 17, wherein the displaying of the presentations in the plurality of presentations is performed such that at least a portion of one or more of the presentations in the plurality of presentations is rendered imperceptible by an optical polarization and/or anaglyph filter.

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

20. The method of claim 19, wherein the displaying of the presentations in the plurality of presentations is performed such that at least a portion of one or more of the presentations in the plurality of presentations is rendered imperceptible by a shutter mechanism blocking a transmission of light during the second time interval.

21. The method of claim 1, wherein prior to the displaying, the method further comprises:

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

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

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

a presentation processor configured to;

receive a first presentation and a second presentation in a plurality of presentations, wherein each of the first presentation and the second presentation comprises one or more images that are human-perceptible, and

subtract the first presentation from the second presentation on a pixel-by-pixel basis to obtain a difference presentation, wherein the difference presentation does not present any human-perceptible images; and

a display device configured to display the first presentation and the difference presentation to reproduce the composite presentation, wherein the composite presentation is human-perceptible as the second presentation;

wherein at least a first portion of the first presentation is selectively revealed to a viewer when viewing the composite presentation via a visual aid.

23. The system of claim 22, wherein the display device is configured to render the first portion of the first presentation imperceptible to the human eye by employing a filtering technique including at least one of polarization, shuttering, depth of field alteration, light intensity alteration and light angle alteration.

24. The system of claim 22, wherein the display device is configured to display the first presentation and the difference presentation simultaneously.

25. The system of claim 24, wherein the display device is configured to display the presentations in the plurality of presentations such that at least a portion of one or more of the presentations in the plurality of presentations is rendered imperceptible by an optical polarization and/or anaglyph filter.

26. The system of claim 22, the display device is configured to display the first presentation and the difference presentation sequentially for a first time interval and a second time interval, respectively.

27. The system of claim 26, wherein the display device is configured to display the presentations in the plurality of presentations such that at least a portion of one or more of the presentations in the plurality of presentations is rendered imperceptible by a shutter mechanism blocking a transmission of light during the second time interval.

28. The system of claim 22 further comprising:

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

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

receiving a first image and a second image in a plurality of images, wherein each of the first image and the second image comprises an image that is human-perceptible;

subtracting the first image from the second image on a pixel-by-pixel basis to obtain a difference image, wherein the difference image does not present a human-perceptible image; and

displaying, via a processor, the first image and the difference image to reproduce the composite image, wherein the composite image is human-perceptible as the second image;

wherein at least a first portion of the first image is selectively revealed to a viewer when viewing the composite image via a visual aid.
