<Screen 54> (An Example)

1 Press “Next”  

 or “Previous” 

 and let the

scanner display Screen 54.

The scanner displays the ID number if the
applicable board is installed.

If the video interface board is installed properly, the display shows “ID=7”.

2 Press

<Screen 55>

1 Press “Next” 

 or 

 and let the scanner

display the Screen 55.

2 At Screen 55, press 

 or 

 to select

“Scanner” or “IPC-4D”.

When “Scanner” is selected, the scanner
uses its built-in image processing.  On the
other hand, the scanner uses the image
processing of the IPC-4D when the IPC-4D is
installed and “IPC-4D” is selected.

The factory default is “Scanner”.

fi-4640S has built-in Image Processing.  The following image processing is supported both by the fi-4640S
and the IPC-4D.  As a default, the scanner built-in functions are enabled.  By setting “On” using the
Operator Panel, the IPC-4D image processing overrides the built-in functions.

3 Simplified Dynamic Threshold

IPC-2 like SDTC

3 x 3 max-min

The functions of the IPC-4D are intended for compatibility with those of the IPC-3/3D (except for image
quality).  The matrix size used in the IPC-4D is larger than the one in the fi-4640S. The fi-4640S Built-in
Dynamic Threshold is a new algorithm.
