To simulate gray or color in a bilevel image with a particular pixel pattern. Sample dither pattern
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...
A technique for simulating more colours or shades of gray than are actually available in the current output device or monitor.
A technique used by a computer to create or rearrange pixels to retouch an image.
To create a gray-scale image by using fixed patterns of black and white pixels to represent each shade of gray. Every time the image needs a particular shade of gray, the software uses the same pattern.
Dithering is a technique used to simulate colors not actually available with the display hardware used
Dithering is the process by which a computer attempts to display an unavailable color by mixing available colors. The blending or dithering gives gives the appearance of the intended color. At times dithered colors look ok, but you may not always be happy with the result. Most web designers use the web safe color palette that consists of 216 color that should not dither on most browsers. This is an example of a dithering color: [ Back
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.
A technique computers use to simulate colors not available in the color display system. Dithering creates adjacent pixels of different colors to give the appearance of a third color. For example, a red color and a yellow color may dither in a mosaic pattern to produce the illusion of an orange color that does not appear in the color palette.y
Dithering is a process whereby missing colors are represented by intermingling pixels of two or more colors in the images palette . Tutorial
To approximate a color that is not part of the current palette by combining pixels of different colors close to each other. Viewed from a distance, it gives the effect of the desired color, but viewed closely, the dots are visible. Dithering can be avoided by selecting non-dithering colors that are compatible with different browsers.
The adjustment of adjacent pixels of different colours to give the illusion of a third colour
Use various patterns of black and white pixels to achieve the effect of grey coloring.
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.
A graphics display or printing process that uses a combination of dots or textures to create the impression of a continuous tone gray scale or color image.
To display a color (on a computer screen or printer) that is not actually available in the system color table. Many systems dither by displaying a pattern of pixels that are close to the desired color, tricking the eye into seeing a color which is not actually present.
If a monitor can't show a certain colour, dithering places pixels that the computer can display close together, to approximate the desired colour. For example, shades of gray can be created by combining black and white pixels on-screen.
The creation of additional colors and shades from an existing palette. Used to create a wide variety of patterns for use as backgrounds, fills, and shading, as well as for creating halftones for printing.
The process of electronically arranging spatial clusters on a displayed or printed image.Black & white process used within the printing industry to represent colour or grey tone images. Similar to Half-Toning as used by the newspaper industry.
The process of simulating color by a combination of small dots of primary colors which, when viewed, appear to mix and form the desired color. Very useful for the Web to correct GIF image output.
To simulate a color on-screen by combining pixels of different colors so that, when viewed from a distance, the effect of the color is achieved. Viewed up close, however, the dots are visible and can give an uneven appearance to an image.
apply Floyd/Steinberg error diffusion to the image
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 to be implied to the eye - it is tricked into blending the color mixture into the intended color. The ratios and pattern of the color mix, along with the resolution of the display device are factors determining the quality of the dithering effect.
To represent gray tones in bitonal output by a pattern of dots.
Since a majority of graphics displays are still 8-bit (and can only display 256 colors simultaneously), special techniques are needed to display images with many more colors present. Dithering simulates additional colors by juxtaposing two different colors to imply a new one. An extreme example of dithering is the display of early Macintoshes, which approximated levels of grays by clusters of small black and white dots.
for digital halftones, the creation of a flat bitmap by simply rutning 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 opposed to deep bitmaps used in gray-scale images.
The adjustment of adjacent pixels of different colors to give the illusion of a third color.
The process of patterning dots of color in an image to achieve the effect of more colors than the current bit-depth permits.
The mixing of adjacent pixels to simulate additional colours when available colours are limited, such as on an 8-bit monitor or an 8-bit palette.
a way of arranging the dots in a digitized image that creates an optical illusion of more continuous colors or gray tones than the computer or device can actually display or print.
The mixing of adjacent pixels to simulate additional colors to fill the gaps between two colors. For instance, if you want to display a full color graphic on a 256-color monitor, the computer will simulate the colors he cannot display. If there is a part in an image that displays incorrectly because a red and a yellow pixel are lying next to each other, creating a definite line from a distance, dithering would put an orange pixel in between to smooth out the line and the colors.
