Generating and displaying spatially offset sub-frames
First Claim
1. A method of displaying an image with a display device, the method comprising:
- receiving a first set of image data for a first image;
generating a first sub-frame and a second sub-frame corresponding to the first set of image data;
reducing a bit-depth of the first and the second sub-frames based on a first set of quantization equations, thereby generating a first dithered sub-frame and a second dithered sub-frame; and
alternating between displaying the first dithered sub-frame in a first position and displaying the second dithered sub-frame in a second position spatially offset from the first position.

Abstract
A method of displaying an image with a display device includes receiving a first set of image data for a first image. A first sub-frame and a second sub-frame corresponding to the first set of image data are generated. A bit-depth of the first and the second sub-frames is reduced based on a first set of quantization equations, thereby generating a first dithered sub-frame and a second dithered sub-frame. The method includes alternating between displaying the first dithered sub-frame in a first position and displaying the second dithered sub-frame in a second position spatially offset from the first position.

16. A system for displaying an image, the system comprising:
-
a buffer adapted to receive a first set of image data for a first image;
an image processing unit configured to define first and second sub-frames corresponding to the first set of image data, and generate corresponding first and second dithered sub-frames by quantizing pixel values of the first sub-frame using a first set of dither values, and quantizing pixel values of the second sub-frame using a second set of dither values; and
a display device adapted to alternately display the first dithered sub-frame in a first position and the second dithered sub-frame in a second position spatially offset from the first position. - View Dependent Claims (17, 18, 19, 20, 21)

22. A system for generating low resolution dithered sub-frames for display at spatially offset positions to generate the appearance of a high resolution image, the system comprising:
-
means for receiving image data for a plurality of high resolution images;
means for generating a plurality of sets of low resolution sub-frames based on the image data, each set of low resolution sub-frames corresponding to one of the high resolution images; and
means for spatially and temporally dithering the plurality of sets of low resolution sub-frames to generate a corresponding plurality of sets of low resolution dithered sub-frames. - View Dependent Claims (23)

24. A computer-readable medium having computer-executable instructions for performing a method of generating low resolution dithered sub-frames for display at spatially offset positions to generate the appearance of a high resolution image, comprising:
-
receiving image data for first and second sets of high resolution images;
generating a plurality of sets of low resolution sub-frames based on the image data, each set of sub-frames corresponding to one of the high resolution images;
quantizing each set of sub-frames corresponding to high resolution images in the first set based on a first plurality of dither values;
quantizing each set of sub-frames corresponding to high resolution images in the second set based on a second plurality of dither values that is different than the first plurality of dither values; and
wherein the quantizing steps provides a spatial and temporal dither of the sub-frames.
