摘要： Present systems and methods enable user-defined image processing parameters to be applied as intended in some regions of a scanned image without applying them in other regions. More specifically, present systems and methods enable a digital reproduction system to automatically adjust for any inherent interactions between separate image processing modules. Present systems and methods need not be concerned about color adjustments that are made by user-defined settings since the system would automatically adjust for interactions between user-defined settings and automatic adjustments that are made by the system. Present systems and methods provide the flexibility that would be obtained by re-arranging the imaging modules in the processing path of an image processing system.
