    Abstract: A projection system includes a projection lens to project image light along an image light path towards a port window and to redirect a portion of the image light away from the image light path as result of being scattered or reflected away from the image light path. The projection system includes a port window for transmitting projected image light from the projection lens. The port window has a surface for redirecting a portion of the projected image light as result of being scattered or reflected away from the image light path. The projection system includes an enclosure positioned between the port window and the projection lens to surround the image light path between the port window and the projection lens. The enclosure absorbs the portion of the image light redirected by the projection lens and absorbs the portion of the projected image light redirected by the surface.

    Abstract: A method for color correcting an input color image having input color values adapted for display on a reference display device having a plurality of input color primaries to account to provide reduced observer metemaric failure on a narrow-band display device. A metamerism correction transform is applied to the input color image to determine an output color image having output color values in an output color space appropriate for display on the narrow-band display device. The metamerism correction transform modifies colorimetry associated with the input colors to provide output color values such that an average observer metameric failure is reduced for a distribution of target observers, and is formed responsive to a distribution of perceived color differences for a set of input colors that are determined for a set of target observers.

    Abstract: Hybrid image projection systems and methods can superimpose image components of an input image. An input image can be divided into smaller regions and at least one parameter of each region can be determined. The input image can be decomposed based on the parameter of each region into multiple, less correlated, orthogonal or quasi-orthogonal image components. Each projector can display respective image components so that the images projected may be optically superimposed on a screen. The superposition of orthogonal or quasi-orthogonal image components can result in superposition of images in an existing multi-projector image systems being more insensitive to inter-projector image misalignment. Superimposing orthogonal or quasi-orthogonal images can be used to avoid visible image degradation, and provide more robust image quality in a multiple projector system implementation.
