Abstract

A method of displaying an image includes receiving image data for the image; buffering the image data for the image, including creating a frame of the image; defining a first sub-frame and at least a second sub-frame for the frame of the image; and displaying the first sub-frame and the second sub-frame, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame.

Claims (95)

1. A method of displaying an image, the method comprising:

receiving image data for the image;

defining a first sub-frame and at least a second sub-frame for the frame of the image; and

displaying the first sub-frame and the second sub-frame, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame,

wherein displaying the first sub-frame and the second sub-frame includes modulating light with a light modulator and producing a first displayed image portion with the first sub-frame and a second displayed image portion with the second sub-frame,

wherein displaying the first sub-frame and the second sub-frame further includes projecting the first displayed image portion and the second displayed image portion with projection optics, and

wherein shifting the displayed image of the second sub-frame includes positioning an optical element in an optical path at least one of before and after the projection optics and moving the optical element between a first position and at least a second position.

2. A method of displaying an image, the method comprising:

receiving image data for the image;

buffering the image data for the image, including creating a frame of the image;

defining a first sub-frame and at least a second sub-frame for the frame of the image; and

displaying the first sub-frame and the second sub-frame, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame,

wherein displaying the first sub-frame and the second sub-frame further includes projecting the first displayed image portion and the second displayed image portion with projection optics, and

wherein shifting the displayed image of the second sub-frame includes positioning an optical element between a first projection element of the projection optics and a second projection element of the projection optics and moving the optical element between a first position and at least a second position.

3. A method of displaying an image, the method comprising:

receiving image data for the image;

buffering the image data for the image, including creating a frame of the image;

defining a first sub-frame and at least a second sub-frame for the frame of the image; and

displaying the first sub-frame and the second sub-frame, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame,

wherein displaying the first sub-frame and the second sub-frame further includes projecting the first displayed image portion and the second displayed image portion with projection optics, and

wherein shifting the displayed image of the second sub-frame includes moving a projection element of the projection optics between a first position and at least a second position.

4. A system for displaying an image, the system comprising:

a buffer adapted to receive image data for the image and buffer the image data to create a frame of the image;

an image processing unit adapted to define a first sub-frame and at least a second sub-frame for the frame of the image; and

a display device adapted to display the first sub-frame and the second sub-frame and shift a displayed image of the second sub-frame, wherein the display device includes an image shifter adapted to shift the displayed image of the second sub-frame, wherein the shift of the displayed image of the second sub-frame is synchronized with display of the second sub-frame,

wherein the display device includes a light modulator adapted to modulate light and produce a first displayed image portion with the first sub-frame and a second displayed image portion with the second sub-frame, and projection optics adapted to project the first displayed image portion and the second displayed image portion,

wherein the image shifter includes an optical element positioned in an optical path at least one of before and after the projection optics, wherein the optical element is adapted to move between a first position and at least a second position to shift the displayed image of the second sub-frame.

5. A system for displaying an image, the system comprising:

a buffer adapted to receive image data for the image and buffer the image data to create a frame of the image;

an image processing unit adapted to define a first sub-frame and at least a second sub-frame for the frame of the image; and

wherein the projection optics include a first projection element and a second projection element, wherein the image shifter includes an optical element positioned between the first projection element and the second projection element, and wherein the optical element is adapted to move between a first position and at least a second position to shift the displayed image of the second sub-frame.

6. A system for displaying an image, the system comprising:

a buffer adapted to receive image data for the image and buffer the image data to create a frame of the image;

an image processing unit adapted to define a first sub-frame and at least a second sub-frame for the frame of the image; and

wherein the image shifter includes a projection element of the projection optics,

wherein the optical element is adapted to move between a first position and at least a second position to shift the displayed image of the second sub-frame.

7. A method of displaying an image with a display device, the method comprising:

receiving image data for the image;

buffering the image data for the image, including creating a frame of the image;

processing the image data for the image, including matching a resolution of the image data to a resolution of the display device, and defining a first sub-frame and at least a second sub-frame for the frame of the image; and

displaying the first sub-frame and the second sub-frame with the display device, including synchronizing shifting a displayed image of the second sub-frame with displaying the second sub-frame;

8. A method of displaying an image with a display device, the method comprising:

receiving image data for the image;

buffering the image data for the image, including creating a frame of the image;
