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
