Class Information
Number: 358/3.21
Name: Facsimile and static presentation processing > Static presentation processing (e.g., processing data for printer, etc.) > Attribute control > Multi-level image reproduction (e.g., gray level reproduction) > Adaptive multi-level image reproduction
Description: Subject matter, not otherwise provided for above, wherein one or more of the multiple discrete density values (gray levels) of an original multi-level image are adaptively processed or reproduced based on a density value or other property of the original multi-level image or of the reproduction, or based on a difference between the original multi-level image and the reproduction.
