• Gamma Pattern
- Gamma correction patterns are used to extend
the availability of the built-in functions. See the manual of the
scanner or device driver for more information.
• White Level Follower -
used to scan a document with a colored
background.
• Density -
defines the level of smoothing as follows:
Scan for image -
less smoothing but includes noise reduction.
Scan for OCR -
extensive smoothing without noise reduction.
• Threshold curve - select Image lightest if the scanned image is
too dark or Image darkest if the scanned image is too bright.
• Gradation -
select
High Contrast
for scanning documents with a
dark background color.
• Equal to White - click the checkbox to reduce the output of e.g.
bold text.
• Noise Removal -
removes stray dots from the background to
reduce unwanted ‘noise’ from the scanned image. Select 5*5 Matrix
to remove all isolated dots.
• Ball-point pen mode -
texts written in ball-point pen have two
lines per stroke. This filter merges the two lines into one to make
the text recognizable to OCR.
• OCR smoothing
- if an image is scanned in low resolution, select
OCR smoothing to reduce jagged edges.

• Outline Extraction
- extracts the edges from images and is used for
image effects and image sensing.
• Mirror
- used to reverse the image.
• Simplified DTC
- effective for scanning images or text on colored
backgrounds. Similar to emphasis but does not emphasize back-

• Automatic Separation
- automatically dithers photos and digitizes
texts in one scanning. Useful for scanning documents containing
both text and photos.
