SCANNING FROM TWAIN AND WIA

Error diffusion, Bayer, and Halftone pattern
Error diffusion, Bayer, and Halftone patterns are the intentional application of noise (dithering) in the image to
help alleviate banding when scanning in binary (black and white) mode. For example, if you scan a color photo in
black and white, the image file will have large blocks of black and white and the image barely recognizable.
Dithering the image creates a black and white image that is recognizable.
Below is an example of a color scan, a black and white scan without dithering, and a black and white scan with
dithering. When the image is scaled down, it may look like a grayscale scan. When the image is at normal size or
enlarged you will be able to clearly see the dithering pattern, as shown in the close-up image.
