Patent ID: 8681172

Claim:
A system for improving legibility of a symbol while rendering the symbol on an electronic display that is coupled to computer system, the system comprising one or more computer processors and computer memory having encoded thereon computer executable instructions which when executed on the one or more processors causes the system to perform a method comprising: measuring a non-color, structural characteristic of the symbol to acquire a value representing a measurement of the structural characteristic; and selecting a color value for a pixel associated with said symbol and to be displayed on the electronic display, wherein selecting the color value is based on the measurement and a color assignment model, the color assignment model comprising a set of rules that correlate one or more color values with one or more structural characteristics, the color assignment model being based upon a color perception model which predicts how colors are perceived by one or more human observers, and wherein said color value comprises each of a chromaticity, luminance, and saturation value, the color value providing a perceivable spatial effect based on a spectral realm wavelength of the selected color value relative to color values of other pixels in or near the symbol.
