Image Scanner User's Manual
¡ Halftone scanning
Function: Halftone creates the illusion of gray scales by simulating shades of gray from pat- terns of black and white dots.
Usage: Use halftone scanning when scaning an image with gray shadings such as a photo- graph, to be printed or displayed on a monochrome device, such as a laser printer. Halftoning saves memory, so it is convenient for filing a large amount of image data. This scanner has eleven halftoning methods: ten dithering methods and one error diffusion method.
