This article introduces dithering, a technique that creates the illusion of more colors by arranging black and white pixels. It explains how dithering simulates gray shades and discusses the ordered dithering method using a threshold map. The author plans to expand on algorithms in future parts.

The article discusses the technique of dithering in image processing, explaining its importance for reducing color depth in images while maintaining visual quality. It covers eleven dithering algorithms, including the well-known Floyd-Steinberg method, and provides insights into how dithering can improve the representation of images on devices with limited color capabilities. The author emphasizes dithering's ongoing relevance in both practical and artistic applications.
