Dithering

Ordered Dithering
... Ordered dithering is an image dithering algorithm ... The algorithm achieves dithering by applying a threshold map on the pixels displayed, causing some of the pixels to be rendered at a different color, depending on how far in between the color is of ... Additionally, because the location of the dithering patterns stays always the same relative to the display frame, it is less prone to jitter than error-diffus ...

Rounding - Dithering and Error Diffusion
... In these circumstances dithering, and a related technique, error diffusion, are normally used ... Floyd–Steinberg dithering is a popular error diffusion procedure when digitising images ...

Dither - Digital Photography and Image Processing - Applications
... One common application of dithering is to more accurately display graphics containing a greater range of colors than the hardware is capable of showing ... For example, dithering might be used in order to display a photographic image containing millions of colors on video hardware that is only capable of showing 256 colors at a time ... Without dithering, the colors in the original image might simply be "rounded off" to the closest available color, resulting in a new image that is a poor ...
