THREE DIMENSIONAL PROJECTION DISPLAY
First Claim
Patent Images
1. A method comprising:
- receiving image information in a form representative of a three dimensional (3D) object;
operating on the received image information to compensate for a projector bias associated with one or more projectors by transforming a projector perspective of the 3D object into a viewing region perspective; and
projecting light corresponding to the operated on image information from each of the one or more projectors through a screen to a viewing region.

Abstract
A display system includes a screen and a plurality of projectors configured to illuminate the screen with light. The light forms a three dimensional (3D) object for display in a viewing region. The system further includes one or more processors configured to generate image information associated with the 3D object. The image information is calibrated to compensate for a projector bias of the plurality of projectors by transforming a projector perspective of the 3D object to a viewing region perspective.

19. A computer-readable medium having instructions stored thereon, wherein when the instructions are executed by at least one device, they are operable to:
-
receive image information to be displayed, in a form representative of a 3D object; distribute at least part of the image information to each projector in an array of projectors; render different parts of the image information to project a distributed image within each projector'"'"'s frustum; operate on the image information prior to rendering the different parts to compensate for a projector bias; illuminate the screen from a different angle corresponding to each projector; and combine the distributed images into a predetermined view of an autostereo image in a view volume. - View Dependent Claims (20, 21, 22, 23)

24. A system comprising:
-
a means for scattering light; means for projecting light on the means for scattering light, the light forming a three dimensional (3D) object for display in a viewing region; and means for generating image information associated with the 3D object, the image information calibrated to compensate for a distortion of the means for projecting light by transforming a display perspective of the 3D object to a viewing region perspective. - View Dependent Claims (25, 26, 27, 28, 29, 30)
