White Level - Kodak 1500 User Manual

White Level

A-63055 December 1999
When White Level is on, the first 3 mm of each document is analyzed
and the background brightness level is adjusted so the background of
the scanned document becomes white. White Level is set to "From
White Stick" when Halftone (Dither) or Grayscale is enabled.
From White Stick—white level is set according to the white level
calibration strip in the scanner (not the scanned document).
From Paper—white level is set from the first 3 mm of a scanned
document.
Automatic—when Halftone (Dither) and Binary are set to "None,"
white level is set from a preset white color definition.
If you scan colored paper (such as red or blue), the scanned paper's
background color may cause the noise level to increase.
NOTE: The document color 3 mm from the upper edge is detected. If
a document contains colors that are different from the 3 mm
sampled section color, this function may not work correctly.
