Dithering

In digital audio engineering dithering is a mathematical process where a random noise is added to the least significant bit of a digital word. With very low level signals, the quantization error becomes correlated to the signal level. This creates a measurable amount of distortion. By adding dither, the correlation between the signal level and the ...

Dithering

The process used by some output devices to simulate shades of gray or color variations with a randomizing technique that uses varying sizes of and shapes of pixel groupings instead of an ordered array of halftone dots.

Dithering

Utilised when images are reduced from 24-bit to 8-bit colour. The dithering algorithm combines pixels of adjacent colours into a dot pattern, simulating unavailable colours. It reduces the posterisation effect that colour depth reduction can create. Photoshop offers two dithering options - the best is Diffusion Dithering.

Dithering

when displaying a picture on a computer screen in, say, a 256 colour mode, it is possible to give the impression of intermediate colours by mixing dots of the different colours in different ratios - this is done using a random displacement of these dots to avoid a patterned effect. This technique is called dithering
