First Claim
Patent Images
1. A method of displaying images with a display system, the method comprising:
- receiving image data for the images;
generating at least a first sub-frame and at least a second sub-frame corresponding to the image data;
projecting the first sub-frame with a first projector onto a target surface; and
projecting the second sub-frame with a second projector onto the target surface at a temporal offset from the projection of the first sub-frame, wherein the first and second projectors are positioned to project sub-frames that spatially overlap on the target surface.

Abstract
A method of displaying images with a display system includes receiving image data for the images. The method includes generating at least a first sub-frame and at least a second sub-frame corresponding to the image data. The first sub-frame is projected with a first projector onto a target surface. The second sub-frame is projected with a second projector onto the target surface at a temporal offset from the projection of the first sub-frame, wherein the first and second projectors are positioned to project sub-frames that spatially overlap on the target surface.

23. A system for displaying images, the system comprising:
-
a buffer adapted to receive image data for the images; a sub-frame generator configured to define first and second pluralities of sub-frames corresponding to the image data; a first projection device adapted to sequentially project the first plurality of sub-frames onto a target surface; and a second projection device adapted to sequentially project the second plurality of sub-frames onto the target surface temporally offset from and temporally interleaved with the projection of the first plurality of sub-frames, wherein the first and second projection devices are positioned to project sub-frames that spatially overlap on the target surface. - View Dependent Claims (24, 25, 26)

27. A system for projecting low-resolution sub-frames onto a viewing surface, comprising:
-
means for receiving high-resolution images; means for generating a first and a second plurality of low-resolution sub-frames based on the high-resolution images; first means for projecting the first plurality of sub-frames; and second means for projecting the second plurality of sub-frames at temporal and spatial offsets from the projection of the first plurality of sub-frames, thereby generating the appearance of high-resolution images. - View Dependent Claims (28)

29. A computer-readable medium having computer-executable instructions for performing a method of generating low-resolution sub-frames for projection onto a viewing surface to give the appearance of high-resolution images, the method comprising:
-
receiving high-resolution images; generating a plurality of low-resolution sub-frames based on the high-resolution images, wherein the low-resolution sub-frames are configured to be projected by a plurality of projectors in a temporally offset, temporally interleaved, and spatially overlapping manner; and performing a sinusoidal modulation of an image characteristic of the generated sub-frames.
