User’s Manual Configuring the Document Server

Type Options

Fujitsu DTC

• 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.

Fujitsu IPC

• 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.

•Emphasis - emphasizes image edges but also emphasizes back-

ground noise (low, medium, high)

• 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-

ground noise.

• Automatic Separation - automatically dithers photos and digitizes

texts in one scanning. Useful for scanning documents containing

both text and photos.
