DITHER MATRIX GENERATION DEVICE, PRINTED MATTER, DITHER MATRIX GENERATION METHOD, PROGRAM, AND IMAGE PROCESSING DEVICE

摘要

There is provided a dither matrix generation device including: cluster section generation means for generating a cluster section formed by a predetermined number of dots of a predetermined size in a matrix having a plurality of dots; empty region specification means for specifying an empty region other than the cluster section in the matrix, a sub-cluster section generation means for generating a sub-cluster formed by a smaller number of dots of a smaller size than the cluster section in the empty region specified by the empty region specification means, and dither value allocation means for generating a dither matrix by allocating a dither value in such a manner that the dither value increases in the order of the cluster section, the sub-cluster section, and other scattered dither section. ® KIPO & WIPO 2008
