WebOrdered Dither • For a constant gray level patch, turn the pixel “on”in a speciﬁed order. • This creates the perception of continuous variations of gray. • An N ×N index matrix speciﬁes what order to use. I2(i,j)= 1 2 3 0 • Pixels are turned on in the following order. Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette. In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels from within the available palette. The human eye perceives the diffusion as a mixture of the colors within it (see color vision). Dithered images, particularly th…

WebOrdered dithering is an improved method, so I would prefer it over random. Try noticing differences when playing upscaled content, like 480p source on a 1080p+ screen and tweak processing options to your preference. WebOrdered dithering is an image dithering algorithm. It is commonly used by programs that need to provide continuous image of higher colors on a display of less color depth. For example, Microsoft Windows uses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns.
