2. At Screen 31, press
When "Standard" is selected, the scanner uses its built-in image processing. On the other hand, the
scanner selects the image processing of the IPC-4D(IMAGE PROCESSING CIRCUIT BOARD) when
the "IPC-4D" is installed and selected.
NOTICE
The factory default is "Standard".
NOTICE
fi-4340C has built-in Image Processing. The following image processing is supported both by the fi-
4340C and the IPC-4D(IMAGE PROCESSING CIRCUIT BOARD). 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
1 Emphasis/Smoothing
2 Outline
3 Simplified Dynamic Threshold
The IPC-4D(IMGGE PROCESSING CIRCUIT BOARD) support of those functions is intended for
compatibility with the IPC-3/3D (except for image quality). The matrix size used in the IPC-4D(IMAGE
PROCESSING CIRCUIT BOARD) is larger than the one in the fi-4340C. The fi-4340C Built-in
Dynamic Threshold is a new algorithm.
