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.

OK

Applies the selected settings and closes the dialog box.

Cancel

Closes the dialog box without applying the selected settings.

Detail

Opens the Detail Settings dialog box.
