grayscale or color image to a bi-tonal

image. There are several different

methods of performing this conversion.

Options: Dynamic Threshold,

Dynamic Threshold (AD), Fixed

Processing, Halftone 1~5, Error

Diffusion.
Dynamic Threshold: Selecting

Dynamic Threshold allows the scanner

to dynamically evaluate each document

to determine the optimal threshold value

to produce the highest quality image.

This is used to scan mixed document

containing faint text, shaded background,

or color background with a single setting.

If Dynamic Threshold is selected,

Threshold, Brightness, and Contrast are

not available.

Dynamic Threshold (AD): Selecting

Dynamic Threshold (AD) to perform

the enhanced mode of the Dynamic

Threshold feature. However, using this

mode may slow down your scanning

speed.

Sensitivity of Dynamic Threshold

Occasionally your scanned image may

contain small dots or speckles. To remove

these spots, increase the sensitivity value

by moving the bar to the right. The value

ranges from 1 to 30. The default is 20.
