Projection of overlapping sub-frames onto a surface
First Claim
Patent Images
1. A method of displaying an image with a display system, the method comprising:
- receiving image data for the image;
generating a first sub-frame and a second sub-frame corresponding to the image data based on a geometric relationship between a hypothetical reference projector and each of a first and a second projector, wherein the hypothetical reference projector is used in an image formation model to represent a projector positioned at any arbitrary location with respect to the first and second projectors;
projecting the first sub-frame with the first projector onto a target surface; and
projecting the second sub-frame with the second projector onto the target surface, wherein the first and the second sub-frames at least partially overlap on the target surface.

Abstract
A method of displaying an image with a display system includes receiving image data for the image. The method includes generating a first sub-frame and a second sub-frame corresponding to the image data based on a geometric relationship between a hypothetical reference projector and each of a first and a second projector. The method includes projecting the first sub-frame with the first projector onto a target surface. The method includes projecting the second sub-frame with the second projector onto the target surface, wherein the first and the second sub-frames at least partially overlap on the target surface.

13. A system for displaying an image, the system comprising:
-
a buffer adapted to receive image data for the image; a sub-frame generator configured to define first and second sub-frames corresponding to the image data; a first projection device adapted to project the first sub-frame onto a target surface; a second projection device adapted to project the second sub-frame onto the target surface, such that the second sub-frame at least partially overlaps the first sub-frame; and wherein the first and the second sub-frames are defined by the sub-frame generator based on a geometric relationship between a hypothetical reference projection device and each of the first and the second projection devices. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A system for generating low-resolution sub-frames for simultaneous projection onto a viewing surface at spatially offset positions to generate the appearance of a high-resolution image, the system comprising:
-
means for receiving a first high-resolution image; means for generating a first plurality of low-resolution sub-frames based on the first high-resolution image; and means for iteratively updating the first plurality of sub-frames based on an error calculated at each iteration, the error based on a difference between the first high-resolution image and a simulated high-resolution image, and wherein the error is down-sampled, filtered, and geometrically transformed before being used to update the first plurality of sub-frames. - View Dependent Claims (26, 27, 28, 29)
