Dithering Algorithm for Color Mode
Signal
…
…
The output sequence obtained in the data output for monochrome mode is shown in
Table 38-8.
Consider now color display mode and two pixels p0 and p1 with the horizontal coordinates
4*n+0, and 4*n+1. A color pixel is composed of three components: {R, G, B}. Pixel p0 will be dis-
played sending the color components {R0, G0, B0} to the display. Pixel p1 will be displayed
sending the color components {R1, G1, B1}. Suppose that the data read from memory and
mapped to the lookup tables corresponds to shade level 10 for the three color components of
both pixels, with the dithering pattern to apply to all of them being DP2_3 = “1101 1011 0110”.
