Method and apparatus for a wide field of view display
First Claim
1. A method of producing a uniform resolution image on a tessellation of spherical surfaces acting as rear-projection screens, the method comprising:
- creating a tessellation of a sphere using spherical surfaces associated with a set of display screens, wherein the tessellation of the spherical surfaces surrounds an eyepoint of a viewer on all sides and a top of the tessellation of the spherical surfaces, wherein each screen in the set of display screens has a selected curvature, wherein a set of projectors generates images for display on the tessellation of the spherical surfaces associated with the set of display screens;
identifying the eyepoint of the viewer positioned inside the tessellation of the set of display screens;
identifying a viewing distance from the eyepoint to each screen in the set of screens;
identifying a projection distance from each projector in the set of projectors to each screen in the set of screens, wherein the selected curvature for each screen is identified based on a relationship between the eyepoint, the viewing distance, and the projection distance, wherein the selected curvature is determined based on a locus of points created by an intersection of lines drawn at equal angular increments from the eyepoint with a set of lines drawn at equal pixel increments at an image source through the projection point; and
displaying a full field of view display with a uniform resolution on a surface of the tessellated sphere of display screens.

Abstract
A method and apparatus for a uniform resolution display screen. In one embodiment, the uniform resolution display screen comprises a surface of the uniform resolution display screen having a curvature configured to display images with a uniform resolution across the display screen. The curvature is based on a projection distance from a projector to the uniform resolution display screen and a viewing distance from an eyepoint of an observer to the uniform resolution display screen. The geometry of the display screen is configured to display images associated with a high definition imaging format.

8. A visual image projection and display system wherein the visual image projection and display system comprises:
-
a tessellation of spherical surfaces acting as rear-projection screens, wherein a geometrically normal ray from a point on a concave side of a first spherical surface in the tessellation of spherical surfaces intersects with a geometric normal ray from a point on a concave side of each other spherical surfaces in the tessellation of spherical surfaces at or near an eye position of an observer; wherein the tessellation of spherical surfaces further comprises a set of side screens, wherein each screen in the set of side screens has a uniform resolution curvature across the surface of the side screen and wherein the screen curvatures are based on a selected eyepoint, a projection distance from a projector to a display screen and a viewing distance from an eyepoint of an observer to the display screen such that the selected curvature is determined using a locus of points created by an intersection of lines drawn at equal angular increments from the eyepoint with a set of lines drawn at equal pixel increments at the image source through the projection point; and a set of projectors located on a convex side of each spherical surface in the tessellation of spherical surfaces, wherein each projector in the set of projectors generates an image to form a plurality of images, and wherein the plurality of images are displayed on the tessellation of spherical surfaces with uniform resolution. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
