Chapter 6 – Adjusting scanned images

o Use the slider to increase or decrease the Contrast.

The Contrast settings determine the contrast between darker and

lighter zones of an image. Use these settings to make character shapes

stand out against a colored background.

(Color image)

(Default contrast settings yield broken characters)

(Increased contrast settings yield satisfactory recognition results)

o Use the slider to increase or decrease the Despeckle options.

Despeckling removes small spots from black-and-white images.

Note that this Despeckling function is not the same as the ones you

find on the Settings menu and under Options on the main toolbar: the

former function applies to binarized images while the latter functions

are applied during scanning.

 Click Apply to preview the results.

 If the results are satisfactory, click OK to save and close the

settings. If not, click Cancel and modify the settings.

 Click Recognize + Save to recognize the document.

Or use the command Save document on the File menu.
