    • A mother matrix pattern MMP is divided into (m.times.n) child matrix patterns CMP.sub.11 -CMP.sub.mn comprising m patterns in the main scanning direction and n patterns in the sub-scanning direction, where the first foot-character denotes the position of each child matrix pattern within the mother matrix pattern in the main scanning direction and the latter foot-character denotes the position thereof in the sub-scanning direction, the mother matrix pattern being expressed by; ##EQU1## and image information corresponding to one mother matrix pattern is obtained with (m.times.n) gradation data ##EQU2## comprising ICD.sub.11 -ICD.sub.mn similarly, information of the child matrix pattern CMP.sub.ij in the mother matrix pattern specified with the gradation data ICD.sub.ij is obtained as information in the form of bit distribution for the gradation data ICD.sub.ij. In other words, the position of each of the child matrix patterns for obtaining image information in accordance with both array of one mother matrix pattern and (m.times.n) gradation data is located in a position corresponding to the position of the gradation data within the mother matrix pattern. The reproduced image is thus formed in such a fashion that (m.times.n) child matrix patterns having information of the respective mother matrix patterns in accordance with the respective gradation data and locating in predetermined positions to constitute one mother matrix pattern are arrayed in an area of the reproduced image corresponding to one mother matrix pattern.
    • 母矩阵模式MMP被划分为包括主扫描方向上的m个图案和副扫描方向上的n个图案的(m×n)个子矩阵图案CMP11-CMPmn,其中第一脚标表示每个子矩阵图案的位置 在主扫描方向上的母矩阵图案和后面的字母表示其在副扫描方向上的位置,母矩阵图案表示为: 使用包含ICD11-ICDmn的(m×n)个灰度数据类似地获得与一个母矩阵模式相对应的图像信息,获得由灰度数据ICDij指定的母矩阵模式中的子矩阵模式CMPij的信息为 灰度数据ICDij的位分配形式的信息。 换句话说,用于根据一个母矩阵模式和(m×n)灰度数据的两个阵列获得图像信息的每个子矩阵模式的位置位于与母矩阵内的灰度数据的位置相对应的位置 模式。 这样形成再现图像,使得(m×n)个子矩阵图案具有根据各个灰度数据的相应母矩阵图案的信息,并且定位在预定位置以构成一个母矩阵图案,排列在 对应于一个母矩阵图案的再现图像。
