Chapter 2 Specifying the Scanner Settings
Brightness
Automatically or manually sets the brightness of the image. If the automatic set-
ting is selected, the brightness is set automatically. When the manual setting is
selected, values from 1 to 255 can be specified, with larger settings increasing the
exposure level on the scanner and giving a brighter image. Smaller values de-
crease the exposure level and produce darker images.
Contrast
When the "Brightness" adjustment is set to Manual, the contrast in the image can
also be adjusted to any value between 1 and 255. If "Brightness" adjustment is set
to Automatic, the contrast cannot be adjusted.
