1640s, "to quake, tremble," phonetic variant of Middle English didderen (late 14c.), which is of uncertain origin. The sense of "vacillate, be anxious" is from 1819. Related: Dithe [..]

A means by which the illusion of new colors and shades is created by varying the pattern of dots; the more dither patterns a device or program supports, the more shades of gray it can represent. Also [..]

Dither is intentionally applied noise that is intended to randomize quantization error. This can have the effect of preventing visible or audible patterns in images and sounds such as contouring that [..]

To simulate a color that is not part of the current palette on-screen (or in print) by combining pixels of different colors close to each other. Viewed from a distance, it gives the effect of the colo [..]

For digital halftones, the creation of a flat bitmap by simply turning dots off or on. All dots are the same size there are simply more of them in dark areas and fewer of them in light areas -- as opp [..]

In digital imaging, to use the colors of two pixels to determine the color of a pixel lying between them. This new pixel thus has a value that is the average of the two pixels on either side of it. Dithering is often used to eliminate unwanted jaggies

To use a pattern of solid dots to simulate more colors than are available when displaying images.

Creating the illusion of new colors and shades by varying the pattern of dots. Newspaper photographs, for example, are dithered. If you look closely, you can see that different shades of gray are produced by varying the patterns of black and white dots. There are no gray dots at all. 

Color dithering simulates a color value that can't be displayed using a mixture of displayable colors, eg: gray can be created by mixing black and white values. This allows non-displayable colors [..]

Dither is positioning noise of the scan mirrors in the time range of a few milliseconds. Independently of their activated motion, scan mirrors oscillate irregularly across a broad frequency spectrum f [..]

A cyclic application of voltage across a solenoid or coil. Most often used to assure that the device driven by the coil or solenoid remains in a state of constant motion, thus reducing breakaway friction.
