Readiris 15 - User Guide
Smoothen color image
This option is selected by default. It smoothens out differences in intensity, creating a greater
contrast between the text and the background. Sometimes smoothening is the only way to separate
text from a colored background.
Fast Binarisation (Readiris Corporate)
When you selected Fast Binarisation in the From File options or in the Scanner Settings
, the same
option is selected in the Adjust Image menu. This option is useful when scanning or opening many
image files at the same time, as it increases the processing speed considerably.
When this option is selected, you cannot manually adjust the Brightness and Contrast options
however. Clear this option to be able to adjust them manually.
Brightness
Move the slider to increase or decrease the brightness of your documents.
Example 1: image is too dark
The image below is too dark and results in a plain black image. There is no text to be recognized.
In this case you need to brighten the image in order for the text to be displayed.
