Abstract

A filter for a camera lens including an electronic display configured to couple to an object side of the camera lens and configured to filter an image on an object side of the electronic display for the camera lens. A controller is configured to electrically control the filtering of the electronic display. An input is for receiving a control for controlling the controller.

Claims

1. A filter for a camera lens, the filter comprising:

an electronic display configured to couple to an object side of the camera lens and configured to filter an image on an object side of the electronic display for the camera lens;

a controller configured to electrically control the filtering of the electronic display; and

an input for receiving a control for controlling the controller.

2. The filter of claim 1, wherein the electronic display includes liquid-crystals therein for filtering the image.

3. The filter of claim 1, wherein the electronic display includes one or more organic light-emitting diodes therein for filtering the image.

4. The filter of claim 1, further comprising a housing coupled to the electronic display, and wherein the controller and the input are positioned within the housing.

5. The filter of claim 4, wherein the housing comprises at least a portion of a frame for the electronic display.

6. The filter of claim 1, wherein the electronic display is configured to removably couple to a matte box for coupling to the camera lens.

7. The filter of claim 1, wherein the electronic display includes a front surface, a rear surface, and one or more side surfaces, and the housing is positioned at the one or more side surfaces.

8. The filter of claim 1, wherein the electronic display includes one or more pixels.

9. The filter of claim 1, wherein the electronic display includes an array of pixels.

10. The filter of claim 1, wherein the electronic display is configured to filter the image on the object side of the electronic display by reducing the amount of light transmitted through the electronic display.

11. The filter of claim 1, wherein the electronic display is configured to filter the image on the object side of the electronic display by diffusing light transmitted through the electronic display.

12. The filter of claim 1, wherein the electronic display is configured to filter the image on the object side of the electronic display by flaring light transmitted through the electronic display.

13. The filter of claim 1, wherein the electronic display is configured to filter the image on the object side of the electronic display by emitting light that is overlaid upon the image.

14. The filter of claim 1, wherein the electronic display is configured to filter the image on the object side of the electronic display for all colors of the image substantially equally.

15. The filter of claim 1, wherein the electronic display includes a first portion and a second portion, the first portion and second portion both configured to allow light to pass therethrough, and the controller is configured to electrically control the filtering of the electronic display such that the first portion filters the image at the same time the second portion does not filter the image.

16. The filter of claim 15, wherein the controller is configured to electrically control the filtering of the electronic display such that the second portion filters the image at the same time the first portion does not filter the image.

17. The filter of claim 1, wherein the input comprises a wireless signal receiver.

18. A filter for a camera system, the filter comprising:

an electronic display configured to couple to a portion of the camera system in an optical path of the camera system and configured to filter an image on an object side of the electronic display for the camera system, the electronic display including one or more organic light emitting diodes;

a controller configured to electrically control the filtering of the electronic display; and

an input for receiving a control for controlling the controller.

19. The filter of claim 18, wherein the filter is configured to couple to the camera system between a camera lens of the camera system and an image receiver of the camera system.

20. The filter of claim 18, wherein the filter is configured to couple to the camera system at an object side of a camera lens of the camera system.

21. The filter of claim 18, wherein the electronic display is configured to filter the image on the object side of the electronic display by emitting light that is overlaid upon the image.

22. A camera system comprising:

a camera including a camera lens;

an electronic display configured to couple to an object side of the camera lens and configured to filter an image on an object side of the electronic display for the camera lens;

a controller configured to electrically control the filtering of the electronic display; and

an input for receiving a control for controlling the controller.

23. The camera system of claim 22, wherein the camera comprises a film camera or a digital camera.

24. The camera system of claim 22, further comprising a matte box, and wherein the electronic display, the controller, and the input are coupled together as a unit that is configured to be removably coupled to the matte box.

25. The camera system of claim 22, wherein the electronic display includes one or more pixels.

26. The camera system of claim 22, wherein the electronic display includes liquid-crystals therein for filtering the image or one or more organic light-emitting diodes therein for filtering the image, or a combination thereof.

27. The camera system of claim 22, further comprising a control terminal for wirelessly connecting to the input to provide the control to the input.

28. A camera system comprising:

a camera including a camera lens;

an electronic display configured to couple to a portion of the camera system in an optical path of the camera system and configured to filter an image on an object side of the electronic display for the camera system, the electronic display including one or more organic light emitting diodes;

a controller configured to electrically control the filtering of the electronic display; and

an input for receiving a control for controlling the controller.

29. The camera system of claim 28, wherein the filter is configured to couple to the camera system between the camera lens and an image receiver of the camera system.

30. The camera system of claim 28, wherein the filter is configured to couple to the camera system at an object side of the camera lens.

31. The filter of claim 28, wherein the electronic display is configured to filter the image on the object side of the electronic display by emitting light that is overlaid upon the image.

32. A method of filtering an image for a camera lens comprising:

filtering, with an electronic display positioned on an object side of the camera lens, the image on the object side of the camera lens for the camera lens.

33. The method of claim 32, further comprising varying the filtering of the electronic display.

34. The method of claim 33, further comprising dynamically varying the filtering of the electronic display.
