Fujitsu M3097DG Table 3.8 Parameter of Gradation

3.3 Optional image function

(2)Gradation

[A.4.7 SET WINDOW command / DTC mode]

Gradation specifies the gamma curve correction before processing Dynamic Threshold. When scanning news papers or old documents which background is dark, it is desirable that the gamma curve has coarse steps in the lighter side and fine steps in the darker side. This is called High Contrast gamma curve.

γcurve

As the Dynamic Threshold with IPC-3D includes an automatic contrast adjustment, High Contrast setting is not required.

Table 3.8 Parameter of Gradation

Parameter	Value	Effect with IPC-2D	Effect with IPC-3D	Default

Ordinary	X’xxx00xxx’	Normal gamma curve	Normal gamma
		(for general document)	curve	X’00’
		(for general document)		X’00’

High Contrast	X’xxx10xxx’	Makes low contrast Image	No effect
		clear

* for dark background document such as newspaper or old document
