Abstract

A method for displaying a content from 4D light field data is described. Such method is executed by an electronic device, and is remarkable in that it comprises changing point of view of the content and/or a focus plane associated with the content, according to viewing rights.

Claims

1. Method for displaying a content from 4D light field data, the method being executed by an electronic device, and being characterized in that it comprises changing point of view of said content and/or a focus plane associated with said content, according to viewing rights.

2. Method for displaying according to claim 1, wherein said changing said point of view of said content and/or said focus plane associated with said content is done randomly in time.

3. Method for displaying according to claim 1, wherein said changing said point of view of said content and/or said changing of said focus plane associated with said content is done based on a random spatial point of a scene associated with 4D light field data.

4. Method for displaying according to claim 1, wherein said changing further comprises blurring at least part of said content.

5. Method for displaying according to claim 4, wherein said blurring comprises adding Gaussian blur to said content.

6. Method for displaying according to claim 4, wherein said blurring is done randomly in time.

7. Method for displaying according to claim 4, wherein said blurring is a spatial blurring of said content that is done randomly.

8. Method for displaying according to claim 1, wherein said content is a 4D light field data.

9. Method for displaying according to claim 1, wherein said content is a 2D image or 2D video.

10. Method for displaying according to claim 1, wherein said content is a 3D content or multiviews content.

11. Method for displaying according to claim 1, wherein a difference value between consecutive changed points of views of said content and/or consecutive changed focus planes is defined as a function of said viewing rights.

12. A computer-readable and non-transient storage medium storing a computer program comprising a set of computer-executable instructions to implement a method for displaying when the instructions are executed by a computer, wherein the instructions comprise instructions, which when executed, configure the computer to perform the method of claim 1.

13. An electronic device for displaying a content from 4D light field data, the electronic device being characterized in that it comprises a changing module configured to changing point of view of said content and/or a focus plane associated with said content, according to viewing rights.

14. The electronic device for displaying according to claim 13, wherein said changing said point of view of said content and/or said focus plane associated with said content is done randomly in time.

15. The electronic device for displaying according to claim 13, wherein said changing said point of view of said content and/or said changing of said focus plane associated with said content is done based on a random spatial point of a scene associated with 4D light field data.
