Image Functions

IPC mode (Auto II mode)

3.3.2
[A.4.7 SET WINDOW command/DTC SELECTION = X'00' or X'80']
In this mode, the algorithm of dynamic threshold is deferent between IPC-2D and IPC-3D.
This mode is recommended for general electric filing purpose.
Option
IPC-2D:
IPC-3D:
a) Simplified Dynamic Threshold
The Simplified Dynamic Threshold is effective to obtain sharp images or capture texts having colored
backgrounds. This effect is similar to Image Emphasis. The difference is that the Simplified Dynamic
Threshold does not emphasis the background. This is useful for forms, checks and most real world
document.
In IPC mode, Simplified Dynamic Threshold was a simplified implementation of the Dynamic
threshold. In IPC-2D, Simplified Dynamic Threshold is no simpler, but sometimes more effective
than Dynamic Threshold for background texts. In IPC-3D, both Dynamic Threshold are the same and
sophisticated.
