Generating and displaying spatially offset sub-frames
First Claim
Patent Images
1. A method of displaying an image with a display device, the method comprising:
- receiving image data for the image at a first resolution;
generating a first sub-frame and a second sub-frame based on combinations of pixel values from the image data, the first and second sub-frames having a second resolution which matches the display device and each have an area equal to the image data; and
controlling an image shifter to allow for alternating between displaying the first sub-frame in a first position and displaying the second sub-frame in a second position spatially offset from the first position on the display device.

Abstract
A method of displaying an image with a display device includes receiving image data for the image. A first sub-frame and a second sub-frame are generated based on combinations of pixel values from the image data. The method includes alternating between displaying the first sub-frame in a first position and displaying the second sub-frame in a second position spatially offset from the first position.

5. A method of displaying an image with a display device, the method comprising:
-
receiving image data for the image; generating a first sub-frame and a second sub-frame based on combinations of pixel values from the image data, wherein the first and the second sub-frames each include a plurality of pixels; assigning a value to each pixel in the first and the second sub-frames based on a weighted sum of a plurality of pixel values from the image data; and alternating between displaying the first sub-frame in a first position and displaying the second sub-frame in a second position spatially offset from the first position. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
