Abstract:
(EN) 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.
(FR) L’invention concerne un dispositif de génération de matrice de superposition comprenant : un moyen de génération de section de grappe destiné à la génération d’une section de grappe formée par un nombre prédéterminé de points de taille prédéterminée dans une matrice ayant une pluralité de points ; un moyen de spécification de région vide destiné à la spécification d’une région vide autre que la section de grappe dans la matrice, un moyen de génération de section de sous-grappe destiné à la génération d’une sous-grappe formée par un nombre inférieur de points de taille inférieure à la section de grappe dans la région vide spécifiée par le moyen de spécification de région vide, et un moyen d’allocation de valeur de superposition destiné à la génération d’une matrice de superposition par l’allocation d’une valeur de superposition d’une manière telle que la valeur de superposition augmente dans l’ordre de la section de grappe, la section de sous-grappe et toute autre section de superposition diffusée.
(JA) 本発明は、複数のドットを有するマトリクスのうち、所定のサイズおよび数のドットから構成されるクラスタ部を生成するクラスタ部生成手段と、前記マトリクスのうち、前記クラスタ部以外の空き領域を特定する空き領域特定手段と、前記空き領域特定手段により特定された空き領域のうち、前記クラスタ部より小さいサイズおよび少ない数のドットから構成されるサブクラスタ部を生成するサブクラスタ部生成手段と、前記クラスタ部、前記サブクラスタ部、それ以外の分散ディザ部の順番でディザ値が大きくなるようにディザ値を割り当てディザマトリクスを生成するディザ値割当手段とを有するディザマトリクス生成装置を提供する。
