or 
to select “Standard” or “IPC4D”.
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 | IPC-4D | fi-4340C |
| | | |
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 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.
