Fujitsu fi-4640S manual Display the TPS Board ID Number, Select Built-In/IPC-4D Image Processing

14. Display the TPS Board ID Number

<Screen 54> (An Example)

1Press “Next” or “Previous” and let the

scanner display Screen 54.

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

NOTICE

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

2Press to return.

15. Select Built-In/IPC-4D Image Processing

<Screen 55>

1Press “Next” or and let the scanner

display the Screen 55.

2At 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.

NOTICE

The factory default is “Scanner”.

NOTICE

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.

	Image Processing	IPC-4D	fi-4640S
1	Emphasis/Smoothing	5 x 5 matrix	3 x 3 matrix
2	Outline	Pre-threshold Laplacian	Laplacian
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.
