Abstract

A system and method for marking a stereoscopic film with colors are provided. The system and method provides for marking a left image with a mark and a right image with a mark having complementary colors, wherein upon viewing, the marks are not visible under certain conditions. The system and method provide for acquiring a stereoscopic image, the stereoscopic image including a first image and a second image, applying a first mark to the first image in a predetermined location, the first mark having a first color, and applying a second mark to the second image in substantially the same predetermined location as in the first image, the second mark having a second color that is different than the first color of the first mark, wherein when viewed in three-dimensional mode, the first mark and the second mark combine into a single mark of one color.

Claims

1. A method for marking, the method comprising the steps of:

acquiring a stereoscopic image, the stereoscopic image including a first image and a second image;

applying a first mark to the first image in a predetermined location, the first mark having a first color; and

applying a second mark to the second image in substantially the same predetermined location as in the first image, the second mark having a second color that is different than the first color of the first mark, wherein when viewed in three-dimensional mode, the first mark and the second mark combine into a single mark of one color.

2. The method of claim 1, wherein the first and second marks are at least one of a text message, object and logo.

3. The method of claim 1, further comprising the steps of:

determining a color of the predetermined location in the first image; and

selecting the first color of the first mark and the second color of the second mark as metameric colors of the color of the predetermined location in the first image.

4. The method of claim 1, further comprising the steps of:

determining a color of the predetermined location in the first image;

spectrally dividing the color into first and second metameric colors; and

wherein the first mark'"'"'s color is the first metameric color and the second mark'"'"'s color is the second metameric color.

5. The method of claim 1, wherein the stereoscopic image is a stereoscopic scene including a sequence of successive frames of first and second images;

and wherein the steps of applying the first and second marks includes applying the first and second marks to each frame of the sequence.

6. The method of claim 1, wherein the stereoscopic image is a stereoscopic scene including a sequence of successive frames of first and second images;

and wherein the steps of applying the first and second marks includes applying the first and second marks to a portion of the plurality of successive frames of the sequence.

7. The method of claim 1, wherein the first and second images include a left eye view and a right eye view of the stereoscopic image.

8. The method of claim 1, further comprising the steps of:

segmenting an object from the first and second image; and

applying the first and second marks to the object.

9. The method of claim 8, further comprising the steps of:

determining a color of the object;

spectrally dividing the at least one color into a first metameric color and a second metameric color;

applying a first metameric color to the first mark; and

applying a second metameric color to the second mark.

10. The method of claim 1, wherein the colors of the first mark and the second mark are at least one of monochromatic and chromatic.

11. A system for marking a film comprising:

means for acquiring a stereoscopic image, the stereoscopic image including a first image and a second image; and

a marking module configured for applying a first mark to the first image in a predetermined location, the first mark having a first color, and applying a second mark to the second image in substantially the same predetermined location as in the first image, the second mark having a second color that is different than the first color of the first mark, wherein when viewed in three-dimensional mode, the first mark and the second mark combine into a single mark of one color.

12. The system of claim 11, wherein the first and second marks are at least one of a text message, object and logo.

13. The system of claim 11, further comprising a color analyzer for determining a color of the predetermined location in the first image and selecting the first color of the first mark and the second color of the second mark as metameric colors of the color of the predetermined location in the first image.

14. The system of claim 11, further comprising color analyzer for determining a color of the predetermined location in the first image and spectrally dividing the color into first and second metameric colors, wherein the first mark'"'"'s color is the first metameric color and the second mark'"'"'s color is the second metameric color.

15. The system of claim 11, wherein the stereoscopic image is a stereoscopic scene including a sequence of successive frames of first and second images and further comprising a sequence analyzer for selecting a plurality of consecutive frames of the sequence to be marked.

16. The system of claim 15, wherein the marking module is further configured to apply the first and second marks to each frame of the selected sequence.

17. The system of claim 15, wherein the marking module is further configured to apply the first and second marks to a portion of the plurality of successive frames of the sequence.

18. The system of claim 11, wherein the first and second images include a left eye view and a right eye view of the stereoscopic image.

19. The system of claim 11, further comprising an object segmentor for segmenting an object from the first image and the marking module is further configured to apply the first and second marks to the object in the first and second images.

20. The system of claim 19, further comprising a color analyzer for determining a color of the object and spectrally dividing the color into at least two metameric colors.

21. The system of claim 11, wherein the colors of the first mark and the second mark are at least one of monochromatic and chromatic.

22. A stereoscopic image, the stereoscopic image comprising:

a first image having a first mark in a predetermined location, the first mark having a first color; and

a second image having a second mark in a substantially same location as the predetermined location in the first image, the second mark having a second color such that when the stereoscopic image is viewed as a three-dimensional image the first mark and the second mark are combined as a single mark of one color and the single mark is not viewable by a viewer of the three-dimensional image.
