    • An image processing device includes storage units to store a first halftone pattern subjected to a halftone processing for a first color gradation value, a second halftone pattern subjected to a halftone processing for a second color gradation value, and a brush pattern. The device further includes shift units to shift each pattern read on the basis of a predetermined unit from each of storage units to a first direction toward a drawing start point on the horizontal line according to a drawing position on the horizontal line, further add each pattern to a second direction toward a drawing end point on the horizontal line, and output each on the basis of the predetermined unit. The device further includes a brush synthesizing unit to select, pixel by pixel, either the first halftone pattern or the second halftone pattern, according to the brush pattern.
    • 一种图像处理装置包括存储单元,用于存储经受第一颜色灰度值的半色调处理的第一半色调图案,经受第二颜色灰度值的半色调处理的第二半色调图案和刷子图案。 该装置还包括移位单元,用于根据水平线上的绘图位置将基于预定单位的每个图案读取的每个图案读取从第一方向移动到水平线上的绘制开始点,进一步添加每个图案 朝向水平线上的绘制终点的第二方向,并且基于预定单位输出。 该装置还包括刷子合成单元,根据刷子图案逐个像素地选择第一半色调图案或第二半色调图案。
