Luminance based multiple projector system
First Claim
1. A method of displaying a high-resolution image with a multi-projector display system, the method comprising:
- determining a luminance profile for each projector;
receiving a high-resolution image frame representative of the high-resolution image;
generating for each projector a low-resolution sub-frame corresponding to the high-resolution image frame based on a geometric relationship between the projector and a reference coordinate system and on the luminance profile of the projector; and
simultaneously projecting each low-resolution sub-frame onto a target surface with the associated projector, wherein the projectors are configured such that the projected low-resolution sub-frames at least partially overlap on the target surface to form a projected image substantially equal to the high-resolution image.

Abstract
A method of displaying a high-resolution image with a multi-projector display system. The method includes determining a luminance profile for each projector, receiving a high-resolution image frame representative of the high-resolution image, and generating for each projector a low-resolution sub-frame corresponding to the high-resolution image frame based on a geometric relationship between the projector and a reference coordinate system and on the luminance profile of the projector. The method includes simultaneously projecting each low-resolution sub-frame onto a target surface with the associated projector, wherein the projectors are configured such that the projected low-resolution sub-frames at least partially overlap on the target surface to form a projected image substantially equal to the high-resolution image.

31. A computer-readable medium having computer-executable instructions for performing a method of generating low-resolution sub-frames for simultaneous projection by a multi-projector display system to form a projected high-resolution image which substantially utilizes a full brightness of the display system, each projector having a luminance profile, the method comprising:
-
receiving a high-resolution image frame representative of the high-resolution image;
generating for each projector a low-resolution sub-frame corresponding to the high-resolution image frame based on a geometric relationship between the projector and a reference coordinate system and on the luminance profile of the projector; and
iteratively updating the low-resolution sub-frame for each projector based on an error between a desired high-resolution image frame and a simulated high-resolution image frame.

32. A display system comprising:
-
a plurality of projectors with each projector configured to project a corresponding low-resolution sub-frame at spatially offset positions on a target surface to form a projected image substantially equal to a high resolution image;
means for determining a luminance profile for each projector;
means for receiving a high-resolution image frame representative of the high resolution image;
