ABBYY® FineReader 15 User’s Guide
Brightness
Changes the scanning brightness.
ABBYY FineReader will display a warning message during scanning if the brightness setting is too
low or too high. You may also need to adjust the brightness setting when scanning in black-and-white
mode.
The 50% setting works well in most cases.
If the resulting image contains too many "sketchy" or "thick" letters, troubleshoot using the table below.
Image defect
Recommendations
This image is suitable for text recognition.
Characters are very thin and sketchy
·
Lower the brightness to make the image darker.
·
Use the grayscale scanning mode (brightness is
adjusted automatically in this mode).
Characters are very thick and are stuck
together
·
Increase the brightness to make the image lighter.
·
Use the grayscale scanning mode (brightness is
adjusted automatically in this mode).
Scanning resolution
Changes the scanning resolution.
Recognition quality depends on the resolution of the document image. Poor image quality may have an
adverse effect on the quality of conversion.
We recommend scanning documents at 300 dpi .
For best recognition results, vertical and horizontal resolutions must be the same.
Setting the resolution too high (over 600 dpi) slows down OCR. Increasing the resolution beyond this
point does not yield substantially improved OCR results.
Setting an extremely low resolution (less than 150 dpi) adversely affects OCR quality.
You may need to adjust the resolution of your images if:
·
The resolution of your image is less than 250 dpi or higher than 600 dpi.
·
If the image has a non-standard resolution.
Some faxes, for example, have a resolution of 204 by 96 dpi.
Crop Image
Lets you select a preset scanning area size or specify the scanning area manually.
