FREQUENCY MODULATION AMPLITUDE MODULATION MIXED NET POINT HIERARCHY CONTINUOUS ADJUSTMENT CONTROL METHOD

摘要

A frequency modulation amplitude modulation mixed net point hierarchy continuous adjustment control method, belongs to a halftone net point generation technical field of an image hard copy field. Based on the available mixed net point generation and net shape controlling etc technologies of multi-bit imaging depth, the method introduces a dithering control algorithm of dynamic hierarchy dividing, and ensures the available FM and AM multi-bit mixed net point technology to have the dynamic adjustment method of hierarchy dividing. Thus the invention resolves net point gradation hierarchy jump which results from that the different hierarchy uses different dynamic net shape controlling means, and exerts effectively hierarchy reproduction effect of multi-bit imaging depth device, and improves quality of halftone mixed net point hierarchy continuous adjustment output and output image of multi-bit depth device.
