Abstract

Method for automatic image reorientation is disclosed. In an embodiment, the method includes reorienting a displayed image in response to a change in relative orientation of a viewer image with respect to a reference image. The reorientation is performed to compensate, at least partially, for the change in relative orientation of the viewer image.

Claims

1. A method of reorienting a displayed image comprising:

responsive to a change in relative orientation of a viewer image with respect to a reference image orientation, reorienting the displayed image to at least partially compensate for said change in relative orientation.

2. The method of claim 1 further comprises acquiring the viewer image.

3. The method of claim 1, wherein the reference image orientation corresponds to an orientation of a previously stored image.

4. The method of claim 1, wherein the reference image orientation corresponds to an orientation of a previously stored image configurable by a viewer.

5. The method of claim 1, wherein reorienting further comprises switching between a plurality of predetermined orientations.

6. The method of claim 5, wherein the predetermined orientations comprises landscape and portrait orientations of the displayed image with respect to the reference image orientation.

7. The method of claim 1, wherein reorienting is performed on receiving an input from a viewer.

8. A system comprising at least one display, one or more processors and a memory coupled to the processor(s), the memory comprising computer-programmable instructions executable by the processor for:

responsive to a change in relative orientation of a displayed image with respect to a viewer image orientation, reorienting the displayed image to at least partially compensate for the change in relative orientation, the viewer image orientation being relative to a reference image orientation.

9. The system of claim 8 further comprising a camera for acquiring the viewer image from a camera associated with the system.

10. The system of claim 8, wherein the reference image orientation corresponds to an orientation of a previously stored image.

11. The system of claim 8, wherein the reference image orientation corresponds to an orientation of a previously stored image configurable by a viewer.

12. The system of claim 8, wherein reorienting further comprises:

selecting one of plurality of predetermined orientations; and

orienting the displayed image based on the selection.

13. The system of claim 12, wherein the predetermined orientations comprises landscape and portrait orientations of the displayed image with respect to the reference image orientation.

14. The system of claim 8, wherein reorienting is performed on receiving an input from a viewer.

15. One or more computer readable media comprising computer executable instructions that, when executed, direct a computing based device to perform acts comprising:

responsive to a change in relative orientation of a viewer image with respect to a reference image orientation, selecting one of plurality of predetermined orientations; and

reorienting a displayed image based on the selected predetermined orientation.

16. The one or more computer readable media of claim 15 further comprising instructions for acquiring the viewer image.

17. The one or more computer readable media of claim 15, wherein the viewer image comprises aspects of viewer'"'"'s face.

18. The one or more computer readable media of claim 15, wherein the reference image orientation corresponds to an orientation of a previously stored viewer image configurable by a viewer.

19. The one or more computer readable media of claim 15, wherein the plurality of predetermined orientations comprises landscape and portrait orientations of the displayed image with respect to the reference image orientation.

20. The one or more computer readable media of claim 15, wherein reorienting is performed on receiving an input from a viewer.
