Dithering is a technique used in digital image processing to reduce the visible effects of quantization. When an image is digitized, each pixel is assigned a specific color value, which is represented by a certain number of bits. The number of bits used to represent each pixel determines the number of colors that can be displayed. Dithering is used to simulate additional colors by introducing noise into the image. This noise is carefully controlled to create the illusion of additional colors. Dithering is commonly used in computer graphics, digital photography, and video processing. One of the key benefits of dithering is that it can help to reduce the visible effects of banding. Banding occurs when there are not enough colors available to represent a smooth gradient. Dithering can help to smooth out these gradients and make them appear more natural. Dithering can also be used to create a variety of textures and shading effects, which can be used to simulate traditional printing techniques like halftone, crosshatch, and stochastic printing. Another important aspect of dithering is that it can be used to reduce the visible effects of color quantization. Color quantization occurs when an image is reduced to a limited number of colors. This can result in visible color artifacts, such as color banding and color blocking. Dithering can help to smooth out these artifacts and make them less noticeable. Overall, dithering is a powerful technique that can be used to improve the visual quality of digital images and videos. By introducing carefully controlled noise into an image, dithering can help to reduce the visible effects of quantization and create the illusion of additional colors and textures.

The word dithering is believed to have originated in the early-1800s, in the context of a printer’s use of the term to refer to a printing technique, which utilized half-tone screens to render graphics with a textured look. Dithering has since acquired a range of meanings, from a description of indecision and hesitation, to a reference to processes involving approximations and simulations, to a technique for manipulating digital audio and video. Despite its multiple applications, the word dithering has retained its original linguistic structure, in which the suffix ‘ing’ marks a process or action. Morphologically, the ‘ing’ is a derivational suffix, used to form verbs from nouns. Here, ‘dit’—a short form of ‘ditto’, which is an example of reduplication—is used to refer to a copying or repeating action. Pragmatically, dit is used as a verb in the progressive tense to indicate an ongoing or in-progress action. Overall, the word dithering has evolved in both its linguistic and historical contexts, yet it retains its morphosyntactic form, semiotic meaning and pragmatic implications.

The term dithering is typically used to denote an indecisive or hesitant approach when making a decision or carrying out a task. It is a complex linguistic concept that transcends cultural and language boundaries. In Arabic, for example, the concept of dithering is expressed with words such as 'yurthabny', 'bayadad', and 'tavoraseny'; in Chinese, with the expressions 'guaixiang' and 'budou'; in French, with the term 'hésiter'; in German, with 'zögern', and in Spanish, with 'dudar'. In Portuguese, the equivalent word used is 'hesitar'; Japanese 'uinku'; Greek 'teizei'; Urdu 'ehtara' and in Hindi 'vichlit karna'. Multilingual speakers of English can also use the words 'waffle', 'prevaricate', 'vacillate', 'falter' and 'perturb' to convey the same meaning when speaking to an international audience.

Dithering is a popular technique used in anime, comic and manga art to create a variety of textures and shading. The technique involves blending two colors together to create a new color by replacing a pixel with two or more pixels of a different hue. This process can be used to simulate the effects of techniques such as blending and shading, or to create a painterly look to an image, as well as to simulate traditional printing techniques like halftone, crosshatch and stochastic printing. Dithering can also be used as a special effect to add texture and movement to a scene.
