Abstract
Color display pixels taken in localized groups are transformed from RGB color signals intended for a self-luminous display into WCMYRGBK signals to drive a chromatophore color display device. Each chromatophoric pixel is of one solid color and is selected from the group (White, Cyan, Magenta, Yellow, Red, Green, Blue, Black). Input luminosity resolution is maintained as output brightness resolution and color fidelity is preserved for the localized group. Separate totals are developed for the Red, Green and Blue components of pixels in a pixel group. A step-repeat process selects a specific chromatophore color for each pixel. As a pixel of the group is processed a chromatophore color is selected which best matches pixel color and the RGB components of the selected chromatophore color is subtracted form the group color totals. Very bright pixels are represented by White, light pixels are represented by Cyan or Yellow or Magenta, dark pixels are represented by Red or Green or Blue. Chromatophore color components are by nature utilized in quantum values. Following processing of a pixel or group of pixels any color remnants are carried over to an adjacent pixel or to the succeeding pixel group. Group RGB colors thus never deviate from the ideal by more than a small value and are recovered in the succeeding pixel group.
