Abstract

An apparatus, a method and a non-transitory computer readable medium is provided. The apparatus includes: at least one processor; and at least one memory storing computer program instructions configured, working with the at least one processor, to cause the apparatus to perform at least the following: detecting bending of a flexible auto-stereoscopic display; and adjusting a parallax barrier arrangement of the flexible auto-stereoscopic display in dependence upon the bending of the flexible auto-stereoscopic display.

Claims

1. An apparatus, comprising:

at least one processor; and

at least one memory storing computer program instructions configured, working with the at least one processor, to cause the apparatus to perform at least the following;

detecting bending of a flexible auto-stereoscopic display; and

adjusting a parallax barrier arrangement of the flexible auto-stereoscopic display in dependence upon the bending of the flexible auto-stereoscopic display.

2. An apparatus as claimed in claim 1, wherein adjustment of the parallax barrier arrangement depends upon where the flexible auto-stereoscopic display is bent.

3. An apparatus as claimed in claim 1, wherein adjustment of the parallax barrier arrangement depends upon the extent to which the flexible auto-stereoscopic display is bent.

4. An apparatus as claimed in claim 1, wherein the parallax barrier arrangement is configured to provide a plurality of opaque regions defining a plurality of slits, and adjusting the parallax barrier arrangement comprises adjusting at least one characteristic of the opaque regions.

5. An apparatus as claimed in claim 4, wherein the at least one characteristic comprises one or more positions of the opaque regions.

6. An apparatus as claimed in claim 4, wherein the at least one characteristic comprises one or more widths of the opaque regions.

7. An apparatus as claimed in claim 1, wherein the positions of a viewer'"'"'s eyes are determined using at least one image captured by one or more image sensors, and the parallax barrier arrangement is adjusted in dependence upon the determined positions.

8. An apparatus as claimed in claim 1, wherein adjustment of the parallax barrier arrangement changes which pixels of the flexible auto-stereoscopic display are viewable by one or both eyes of a viewer.

9. An apparatus as claimed in claim 1, wherein the computer program instructions are configured, working with the at least one processor, to cause the apparatus to:

change how auto-stereoscopic image content is displayed by pixels of the flexible auto-stereoscopic display, in accordance with adjustment of the parallax barrier arrangement.

10. An apparatus as claimed in claim 1, wherein the computer program instructions are configured, working with the at least one processor, to cause:

an output to be provided to a viewer, following the bending of the flexible auto-stereoscopic display, which is associated with a switch from the flexible auto-stereoscopic display displaying a stereoscopic image to the flexible auto-stereoscopic display displaying a non-stereoscopic image.

11. An apparatus as claimed in claim 1, wherein the computer program instructions are configured, working with the at least one processor, to cause:

the flexible auto-stereoscopic display to change from displaying a stereoscopic image to displaying a non-stereoscopic image, in dependence upon the bending of the flexible auto-stereoscopic display.

12. An apparatus as claimed in claim 1, further comprising the flexible auto-stereoscopic display which includes a display panel and the parallax barrier arrangement.

13. A method, comprising:

detecting bending of a flexible auto-stereoscopic display; and

adjusting a parallax barrier arrangement of the flexible auto-stereoscopic display in dependence upon the bending of the flexible auto-stereoscopic display.

14. A method as claimed in claim 13, wherein the parallax barrier arrangement is configured to provide a plurality of opaque regions defining a plurality of slits, and adjusting the parallax barrier arrangement comprises adjusting at least one characteristic of the opaque regions.

15. A method as claimed in claim 13, wherein the at least one characteristic comprises one or more positions of the opaque regions and/or one or more widths of the opaque regions.

16. A method as claimed in claim 13, further comprising:

changing how auto-stereoscopic image content is displayed by pixels of the flexible auto-stereoscopic display, in accordance with adjustment of the parallax barrier arrangement.

17. A non-transitory computer readable medium storing computer program instructions that, when performed by at least one processor, cause at least the following to be performed:

detecting bending of a flexible auto-stereoscopic display; and

adjusting a parallax barrier arrangement of the flexible auto-stereoscopic display in dependence upon the bending of the flexible auto-stereoscopic display.

18. A non-transitory computer readable medium as claimed in claim 17, wherein the parallax barrier arrangement is configured to provide a plurality of opaque regions defining a plurality of slits, and adjusting the parallax barrier arrangement comprises adjusting at least one characteristic of the opaque regions.

19. A non-transitory computer readable medium as claimed in claim 17, wherein the at least one characteristic comprises one or more positions of the opaque regions and/or one or more widths of the opaque regions.

20. A non-transitory computer readable medium as claimed in claim 17, further comprising:

changing how auto-stereoscopic image content is displayed by pixels of the flexible auto-stereoscopic display, in accordance with adjustment of the parallax barrier arrangement.
