OmniPage Pro Settings - 68
Brightness
The Brightness option for scanning a page is like the brightness setting
used on a copy machine. This setting can compensate for variations in
paper and print quality, so it can have a big influence on OCR accuracy.
Click the Brightness check box to activate the adjustment (lighten or
darken) for the brightness of the entire page. This is the only available
Scanner option if you have a black-and-white (Monochrome) scanner.
Contrast
The Contrast option for scanning a page is like the contrast setting used
on a television. This setting is only activated if you have Grayscale or
Color selected in the Scanner settings, and can compensate for variations
in the gray shades or color tones used for text on the page. Depending
on the gray or color content of the page, this setting can have a big
influence on OCR accuracy.
Click the Contrast check box to activate the adjustment (lighten or
darken) for the brightness of the entire page. The Contrast setting is not
available if you have a black-and-white (Monochrome) scanner.
To manually adjust the
brightness, drag the box in
the scrollbar or click the
arrow buttons.
To manually adjust the contrast,
drag the box in the scrollbar or
click the arrow buttons.
