Method for adapting a number of views delivered by an auto-stereoscopic display device, and corresponding computer program product and electronic device

1. A method for adapting a number of views delivered by an auto-stereoscopic display device having sub-pixels, said method being executed by an electronic device, and comprising:

determining a number of views based on information related to said auto-stereoscopic display device and a handshake mechanism with said auto-stereoscopic display device, said information comprising: 1) a list of number of views supported by said auto-stereoscopic display device and 2) at least an information indicative of a computing power of a device needed to deliver content for each view, wherein said list of number of views comprises at least two different number of views;

obtaining a correspondence map between said sub-pixels of said auto-stereoscopic display device and said number of views; and

providing content to said sub-pixels of said auto-stereoscopic display device according to said correspondence map to adapt said number of views delivered by said auto-stereoscopic display device having said sub-pixels.

2. The method according to claim 1 , wherein said determining further uses information indicative of a resolution of said auto-stereoscopic display device.

3. The method according to claim 1 , wherein said determining further uses information derived from a list of frame rates supported by said auto-stereoscopic display device.

4. The method according to claim 1 , wherein said determining further uses information provided by a user, and/or information related to a program which is associated with said content.

5. The method according to claim 1 , wherein determining a number of views is done regularly during a time slot.

6. The method according to claim 1 , wherein said obtaining a correspondence map comprises obtaining an identifying element associated with said correspondence map.

7. The method according to claim 1 , wherein said obtaining a correspondence map comprises executing a piece of code comprising a set of features linked to said auto-stereoscopic display device.

8. A computer and non-transient storage medium storing a computer program comprising a set of computer-executable instructions to implement a method for adapting a number of views delivered by an auto-stereoscopic display device having sub-pixels when the instructions are executed by a computer, wherein the instructions comprise instructions, which when executed, configure the computer to perform a method for adapting a number of views delivered by an auto-stereoscopic display device, said method comprising:

determining a number of views based on information related to said auto-stereoscopic display device and a handshake mechanism with said auto-stereoscopic display device, said information comprising: 1) a list of number of views supported by said auto-stereoscopic display device and 2) at least an information indicative of a computing power of a device needed to deliver content for each view, wherein said list of number of views comprises at least two different number of views;

obtaining a correspondence map between said sub-pixels of said auto-stereoscopic display device and said number of views; and

providing content to said sub-pixels of said auto-stereoscopic display device according to said correspondence map to adapt said number of views delivered by said auto-stereoscopic display device having said sub-pixels.

9. An electronic device for adapting a number of views delivered by an auto-stereoscopic display device having sub-pixels, wherein it comprises:

a first module configured to determine a number of views based on information related to said auto-stereoscopic display device and a handshake mechanism with said auto-stereoscopic display device, said information comprising: 1) a list of number of views supported by said auto-stereoscopic display device and 2)at least an information indicative of a computing power of a device needed to deliver content for each view, wherein said list of number of views comprises at least two different number of views;

a second module configured to obtain a correspondence map between said sub-pixels of said auto-stereoscopic display device and said number of views; and

a third module configured to provide content to said sub-pixels of said auto-stereoscopic display device according to said correspondence map to adapt said number of views delivered by said auto-stereoscopic display device having said sub-pixels.

10. The electronic device according to claim 9 , wherein said first module configured to determine further uses information indicative of a resolution of said auto-stereoscopic display device.

11. The electronic device according to claim 9 , wherein said first module configured to determine further uses information derived from a list of frame rates supported by said auto-stereoscopic display device.

12. The electronic device according to claim 9 , wherein said first module configured to determine further uses information provided by a user, and/or information related to a program which is associated with said content.

13. The electronic device according to claim 9 , wherein said first module configured to determine a number of views is activated regularly during a time slot.

14. The electronic device according to claim 9 , wherein said second module configured to obtain a correspondence map uses an identifying element associated with said correspondence map.

15. The electronic device according to claim 9 , wherein said second module is further configured to execute a piece of code comprising a set of features linked to said auto-stereoscopic display device.
