Setting Threshold
Setting Threshold
The brightness of color and grayscale images is expressed in a value between 0 and 255. However, in
creating black and white images, all colors are mapped to either black (0) or white (255). Threshold is
the borderline value that determines a color as black or white. By adjusting the threshold level, you can
sharpen text in a document or reduce show-through in newspapers.
This function is available when Color Mode is Black and White.
In ScanGear's Advanced Mode, click
(Threshold).
Adjusting Threshold
Move
(slider) to the right to increase the threshold value and thus increase the black areas. Move the
slider to the left to decrease the value and thus increase the white areas. You can also enter a value (0 to
255).
Note
Click Defaults to reset all adjustments in the current window.
