Abstract:
A system for rendering color images on an electro-optic display when the electro-optic display has a color gamut with a limited palette of primary colors, and/or the gamut is poorly structured (i.e., not a spheroid or obloid). The system uses an iterative process to identify the best color for a given pixel from a palette that is modified to diffuse the color error over the entire electro-optic display. The system additionally accounts for variations in color that are caused by cross-talk between nearby pixels.

Claim (Index 17):
A method for estimating an achievable gamut in a color electro-optic display, the method comprising:\n (1) measuring a test pattern to derive information about cross-talk among adjacent primaries in a color electro-optic display; (2) converting the measurements from step (1) to a blooming model that predicts the displayed color of arbitrary patterns of primaries on the color electro-optic display; (3) predicting actual display colors of patterns that would normally be used to produce colors on the convex hull of the primaries using the blooming model derived in step (2) (i.e. the nominal gamut surface); (4) describing the realizable gamut surface using the predictions made in step (3); and (5) rendering a color set by mapping input (source) colors to device colors using the realizable gamut surface model derived in step (4).
