Abstract

A method comprising determining that light reflected by a display obstructs view of the display, and causing compensation for reflected light based on the determination that light reflected by a display obstructs view of the display is disclosed.

Claims

1. An apparatus, comprising:

a processor;

memory including computer program code, the memory and the computer program code configured to, working with the processor, cause the apparatus to perform at least the following;

determining that light reflected by a display obstructs view of, at least part of, the display; and

causing compensation for reflected light based, at least in part, on the determination that light reflected by a display obstructs view of, at least part of, the display.

2. The apparatus of claim 1, wherein compensation for reflected light comprises varying at least one reflective property of the display.

3. The apparatus of claim 2, wherein varying the reflective property comprises varying polarity of at least part of the display.

4. The apparatus of claim 2, wherein varying the reflective property comprises varying texture of at least part of the display.

5. The apparatus of claim 1, wherein compensation for reflected light comprises compensating information that is caused to be displayed on the display.

6. The apparatus of claim 5, wherein compensating information comprises utilizing a predetermined compensated set of information and causing display of at least part of the predetermined compensated set of information on the display.

7. The apparatus of claim 5, wherein compensating information comprises causing compensation generation of the information that is caused to be displayed.

8. The apparatus of claim 1, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, determining that light reflected by a display does not obstruct view of, at least part of, the display, and causing ceasing of compensation for reflected light based, at least in part, on the determined non-obstruction.

9. The apparatus of claim 1, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, determining, at least one of position or orientation, of a light source in relation to the display, wherein determining that light reflected by a display obstructs view of, at least part of, the display is based, at least in part, on the determined, at least one of position or orientation, of the light source.

10. The apparatus of claim 9, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, determining, at least one of position or orientation, of the display and determining, at least one of position or orientation, of the light source, wherein, at least one of position or orientation, of the light source in relation to the display is determined based, at least in part, on the, at least one of position or orientation, of the light source and, at least one of position or orientation, of the display.

11. The apparatus of claim 10, wherein determining, at least one of position or orientation, of the light source comprises retrieving information indicating, at least one of position or orientation, of the light source.

12. The apparatus of claim 9, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, receiving an image indicating the light source, wherein determining, at least one of position or orientation, of the light source in relation to the display is based, at least in part, on the image of the light source.

13. The apparatus of claim 12, wherein determining, at least one of position or orientation, of the light source in relation to the display is based, at least in part, on, at least one of position or orientation, of a camera that captured the image.

14. The apparatus of claim 9, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, monitoring relative movement between the display and the light source, wherein determining, at least one of position or orientation, of the light source in relation to the display is based, at least in part, on the movement and a previously determined, at least one of position or orientation, of the light source in relation to the display.

15. The apparatus of claim 1, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, determining orientation of the display, wherein determining that light reflected by a display obstructs view of, at least part of, the display is based, at least in part, on the orientation of the display.

16. The apparatus of claim 1, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, determining, at least one of position or orientation, of a viewer of the display in relation to the display.

17. The apparatus of claim 16, wherein the memory and the computer program code are further configured to, working with the processor, cause the apparatus to perform, at least, receiving an image indicating, at least one of position or orientation, of viewer of the display in relation to the display, wherein determining, at least one of position or orientation, of the viewer of the display in relation to the display is based, at least in part, on the image.

18. The apparatus of claim 16, wherein the viewer is a person.

19. The apparatus of claim 18, wherein determination of, at least one of position or orientation, of the person in relation to the display is based, at least in part, on face tracking.

20. The apparatus of claim 1, wherein determining that light reflected by a display obstructs view of, at least part of, the display is performed in response to determination that a lighting condition is conducive to light reflected by the display obstructing, at least part of, view of the display.

21. The apparatus of claim 1, further comprising the display.

22. An apparatus comprising:

means for determining that light reflected by a display obstructs view of, at least part of, the display; and

means for causing compensation for reflected light based, at least in part, on the obstruction determination.

23. A method comprising:

determining that light reflected by a display obstructs view of, at least part of, the display; and

causing compensation for reflected light based, at least in part, on the determination that light reflected by a display obstructs view of, at least part of, the display.

24. A computer-readable medium encoded with instructions that, when executed by a computer, perform:

determining that light reflected by a display obstructs view of, at least part of, the display; and

causing compensation for reflected light based, at least in part, on the determination that light reflected by a display obstructs view of, at least part of, the display.
