"Dithering is a method for converting images from one color space into a typically more limited one (e.g., for displaying them on a black and white monitor). Besides that conversion, dithering has the goal of minimizing the loss of image information and detail.

Floyd–Steinberg dithering is an image dithering algorithm first published in 1976 by Robert W. Floyd and Louis Steinberg.

WebJan 1, 2024 · On the right, Floyd-Steinberg dithering was used and the amount of detail is much improved. Although modern displays don’t usually require any dithering, there are cases where it can make a subtle difference to the final quality of an image. For this reason, the RDK provides two kinds of dithering, Simple Noise and Floyd Steinberg.
