Sensitivity / Threshold
Sensitivity (available when you select Dynamic Threshold or Auto Color Detection)
Sensitivity of Dynamic Threshold:
If your document contains small dots or speckles and you want to remove them, increase the sensitivity
value by moving the bar to the right.
Sensitivity of Auto Color Detection:
If your document contains primarily black and white text with a small amount of light or pale color that you
do not want to be recognized as color, reduce the sensitivity value by moving the bar to the left.
Threshold (available when you select Fixed Processing or Document)
A low threshold value produces a lighter image, and can be used to subdue backgrounds and unneeded
information. A high threshold value produces darker images, and can be used to help faint images
stand out.
Brightness
Use the Brightness bar to lighten or darken an image. The greater the value, the clearer the image.
Contrast
Use the Contrast bar to adjust the range between the darkest and the lightest shades in the image.
The greater the value, the greater the difference between light and dark.
Resolution (dpi)
Select a resolution value from the drop-down list. The greater the value, the higher the resolution, and larger
the file size.
You can set a custom resolution value by clicking the button to the right of the drop-down list.
Invert
Use Invert to reverse the brightness and the colors in the image. The default setting is Black on White
background. To reverse this, select White on Black.
