Abstract

In one embodiment, the present invention is directed to an imaging device. The imaging device comprises a near-eye viewfinder that is operable to display an image using image data associated with the imaging device; and a viewing structure that is adapted to be placed over the near-eye viewfinder, wherein the viewing structure comprises a screen member that is operable to partially scatter light associated with the displayed image thereby permitting the image to be viewed from a greater field of view than the near-eye viewfinder provides.

Claims

1. An imaging device, comprising:

a near-eye viewfinder that is operable to display an image using image data associated with said imaging device; and

a viewing structure that is adapted to be placed over said near-eye viewfinder, wherein said viewing structure comprises a screen member that is operable to partially scatter light associated with said displayed image thereby permitting said image to be viewed from a greater field of view than said near-eye viewfinder provides.

2. The imaging device of claim 1 wherein said viewing structure possesses an aperture that possesses a size that approximately corresponds to a viewable area of said near-eye viewfinder.

3. The imaging device of claim 2 wherein said screen member is larger than said aperture, said viewing structure further comprising:

an optic that is operable to optically enlarge said image for projection on said screen member.

4. The imaging device of claim 1 wherein said screen member is constructed of material selected from the list of:

glass and plastic.

5. The imaging device of claim 1 wherein said screen member comprises a coating that is operable to scatter light associated with said displayed image.

6. The imaging device of claim 1 wherein said viewing structure comprises:

at least one attaching member for coupling said viewing structure to said near-eye viewfinder.

7. The imaging device of claim 6 wherein said at least one attaching member is operable to exert a force against said near-eye viewfinder to hold said viewing structure in place when said viewing structure is placed over said near-eye viewfinder.

8. The imaging device of claim 1 wherein said viewing structure comprises a substantially opaque frame that shields said screen member from ambient light.

9. The imaging device of claim 1 wherein said imaging device is operable in a first mode of operation that displays said image at a first power and is operable in a second mode of operation that displays said image at a second power that is higher than said first power.

10. The imaging device of claim 9 wherein said digital imaging device is operable to switch from said first mode of operation to said second mode of operation in response to placement of said viewing structure over said near-eye viewfinder.

11. A method of operating an imaging device, comprising:

displaying an image on a near-eye viewfinder; and

attaching a viewing structure to said near-eye viewfinder, wherein said viewing structure comprises a screen member that is operable to partially scatter light associated with said displayed image to permit said image to be viewed from a greater field of view than said near-eye viewfinder provides.

12. The method of claim 11 wherein said viewing structure comprises an aperture that is approximately equal in size to a viewing area of said near-eye viewfinder.

13. The method of claim 12 wherein said screen member is larger that said aperture, said method further comprising:

optically enlarging said image for projection on said screen member.

14. The method of claim 11 wherein said screen member comprises material selected from the list consisting of:

glass and plastic.

15. The method of claim 11 wherein said screen member comprises a coating that is operable to scatter light associated with said displayed image.

16. The method of claim 11 further comprising:

detecting when said viewing structure is attached to said near-eye viewfinder by a sensor of said imaging device.

17. The method of claim 11 further comprising:

increasing display power associated with said displayed image.

18. The method of claim 17 wherein said increasing display power occurs autonomously in response to sensing said viewing structure is attached to said near-eye viewfinder.

19. The method of claim 17 wherein said increasing display power occurs in response to a user input.

20. The method of claim 11 further comprising:

shielding said screen member from ambient light with an opaque frame of said viewing structure.

21. A viewing structure that is operable to permit a near-eye viewfinder to be utilized simultaneously by a plurality of users of a digital imaging device, said viewing structure comprising:

an aperture adapted to said near-eye viewfinder;

a screen member that is operable to partially scatter light associated with an image displayed by said near-eye viewfinder permitting said image to be viewed from a greater field of view than said near-eye viewfinder provides; and

a frame member that is operable to shield ambient light from said screen member.

22. The viewing structure of claim 21 wherein said screen member is larger than said aperture, said viewing structure further comprising:

an optic that is operable to optically enlarge said displayed image for projection on said screen member.

23. The viewing structure of claim 21 wherein said screen member is constructed of material selected from the list of:

glass and plastic.

24. The viewing structure of claim 21 further comprising:

at least one attaching member for coupling said viewing structure to said near-eye viewfinder.
