With dithering, the distortion is transformed into noise. Ordered dithering is an image dithering algorithm. Stochastic rounding is a way to achieve 1-dimensional dithering. The error diffusion techniques were some of the first methods to generate blue-noise dithering patterns. Dithering introduces noise or a pattern into an image, and often the patterning is visible. Some LCDs may use temporal dithering to achieve a similar effect. This allows expressing each distinct tone of the input with different dithering patterns. This can be good noise for dithering. There are several algorithms designed to perform dithering. This can be done by either using the closest color, or by using dithering. Forced dithering can largely overcome this problem. He said he built a style of dithering in his shows without even realising it. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". In these circumstances, dithering, and a related technique, error diffusion, are normally used. Bayer is also known for his recursively defined matrix used in ordered dithering.
