Abstract (en)
[origin: EP2388773A2] A method may include receiving data pixels of a color image and mapping the color image to display pixels of a display device. Data pixels may have first and second color components, each component having an associated color property. Display pixels may have two or more sub-pixels. The mapping may include mapping a first color component of a first data pixel to a first sub-pixel of a first display pixel, mapping a second color component of a second data pixel to a second sub-pixel of the first display pixel, and storing the first and second color components in a memory. One or more sub-pixel locations in a color filter array map may be selected to diffuse quantization error. The method may include determining a first quantized color component, determining a first quantization error, and diffusing the first quantization error to the selected one or more sub-pixel locations. An embodiment is directed to a processor.
