<p>An image processing system uses probability error diffusion, and is implemented using a variety of devices capable of reproducing image data including color photocopy machines, color facsimiles, color printers, black and white printers, and digital printers. The image processing system is employed in a multi-functional peripheral capable of performing several functions. The image processing system identifies which channels in a printing device will print a pixel, and applies error diffusion to those channels. The image processing system determines characteristics of the pixel and subsequently calculates a pixel placement probability, and then applies the error diffusion to the pixel placement probability. Error diffusion may also be applied to a difference between the pixel placement probability and a print probability.</p> |
