Abstract
A method of displaying images with a display device includes receiving image data for a plurality of image frames. At least one sub-frame for each image frame is generated based on the received image data. The sub-frames for each image frame in a first set of the plurality of image frames are displayed at a first plurality of spatially offset positions. The sub-frames for each image frame in a second set of the plurality of image frames are displayed at a second plurality of spatially offset positions that is different than the first plurality of spatially offset positions.

A method of displaying images with a display device, the method comprising:
- receiving image data for a plurality of image frames;
- generating at least one sub-frame for each image frame based on the received image data;
- displaying the sub-frames for each image frame in a first set of the plurality of image frames at a first plurality of spatially offset positions;
- displaying the sub-frames for each image frame in a second set of the plurality of image frames at a second plurality of spatially offset positions that is different than the first plurality of spatially offset positions;
- and
- sequentially displaying a plurality of colors during the display of each of the sub-frames.
A system for displaying images, the system comprising:
- a buffer adapted to receive image data for first and second images;
- an image processing unit configured to define first and second sub-frames corresponding to the first image, and define third and fourth sub-frames corresponding to the second image;
- and
- a display device adapted to alternately display the first sub-frame in a first position and the second sub-frame in a second position spatially offset from the first position, and alternately display the third sub-frame in a third position spatially offset from the first position and the second position, and the fourth sub-frame in a fourth position spatially offset from the first position, the second position, and the third position, wherein the display device is adapted to use pulse-width modulation to represent different light intensities in the displayed sub-frames.
A system for displaying low resolution sub-frames at spatially offset positions to generate the appearance of a high resolution image, the system comprising:
- means for receiving a set of consecutive high resolution images;
- means for generating a plurality of low resolution sub-frames for each of the high resolution images;
- means for alternately displaying the low resolution sub-frames for each of the high resolution images at a set of spatially offset positions;
- means for automatically varying the set of spatially offset positions for at least one of the high resolution images;
- and
- means for sequentially displaying a plurality of colors during the display of each of the low-resolution sub-frames.
A computer-readable medium storing computer-executable instructions for performing a method of displaying low resolution sub-frames at spatially offset positions to generate the appearance of a high resolution image, comprising:
- receiving a set of consecutive high resolution images;
- generating a set of low resolution sub-frames for each of the high resolution images;
- alternately displaying the low resolution sub-frames for each of the high resolution images at a plurality of spatially offset positions;
- automatically varying the plurality of spatially offset positions for at least one of the high resolution images;
- and
- generating light pulses of varying widths to represent different light intensities in the displayed low resolution sub-frames.
