Correcting Images and Adjusting Colors

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.
