Image Emphasis; Image Processing; Mirror Image - Fujitsu fi-4340C Operator's Manual

Image emphasis

Density is decreased for lighter but not completely white areas adjacent to black areas. Weakening this
emphasis eliminates spot noise or produces softened images.

Image processing

An image is read with specified parameters.
Interface
The connection that allows communication from one part of a system to another. For example, electrical
signals are transferred between the computer and scanner over an interface cable.
Inversion (Reverse-image reading)
In reverse-image reading, data is changed from black to white and vice versa.
IPC preset mode
While reading binary images, it is necessary to set the scanner according to the quality of the sheet to be
read. In this mode, these settings can be performed in advance by corresponding each setting to a pattern
number.
IPC-4D
Image processing option of this scanner.
IRAS
Initialization of the hardware.
Landscape orientation
A document is transported and read with the long side vertical to the moving direction.
Letter size
A standard paper size used in the U.S.A. and other countries. Paper size is 8-1/2 x 11 inches.
Linedrawing mode
Selecting linedrawing mode makes threshold and contrast settings effective but prevents brightness from
being set. The specified threshold value determines whether black or white pixels are scanned. Line
drawing mode is therefore appropriate for scanning text and line art images.
Manual Feed mode = Manual Mode
Requires the operator to feed each document manually into the ADF paper chute.
Manual start mode (<-> automatic start mode)
The reading operation is activated by pressing the START button in this mode. Available only when video
option board is installed.

Mirror image

The read image is symmetrically flipped to produce a mirror image of the original detected in the main
scanning direction.
