    • An image processing method generates a halftone image by forming a halftone dot represented by a set of one or plural output dots corresponding to an intensity of an input image signal while making a part of the dots constituting the halftone dot to be an actual non-output dot so as to reduce an amount of a coloring material of a halftone-dot portion. The image processing method includes holding in a predetermined storage medium halftone-dot profile data for forming the halftone dot corresponding to the intensity of the image signal and gap-size profile data representing a size of a set of the non-output dot; and generating the halftone dot comprising a gap having a size based on the gap-size profile data, a size of the halftone dot being based on the halftone-dot profile data.
    • 图像处理方法通过形成由与输入图像信号的强度相对应的一个或多个输出点的集合所表示的半色调点,同时使构成半色调点的一部分点成为实际的非输出 点以减少半色调点部分的着色材料的量。 图像处理方法包括:在预定的存储介质中保持半色调曲线数据,用于形成与图像信号的强度对应的半色调点,以及表示非输出点的集合的大小的间隙尺寸分布数据; 以及产生包括基于所述间隙尺寸轮廓数据的尺寸的间隙的所述半色调点,所述半色调点的尺寸基于所述半色调点轮廓数据。

    • To reduce low-frequency moiré in secondary colors and tertiary colors in four color screens, between at least two halftone screens, screen vectors wa2, wb2 are arranged to match each other, while other screen vectors are arranged not to match each other. A halftone screen is an orthogonal screen in which screen vector wa2 is perpendicular to basis vector ra1. A halftone screen is a non-orthogonal screen in which screen vector wb2 is perpendicular to basis vector rb1. When screen vector wa2 matches screen vector wb2, spatial frequency spectra corresponding to screen vectors wa2 and wab2, match each other. With such a relationship, because a pair of spatial frequency spectra can match each other between two colors, wider intervals can be provided for the spatial frequency spectra of the remaining colors of four colors, which would suppress low-frequency moiré.
    • 为了减少四色屏幕中的次级颜色和三级颜色的低频波纹,在至少两个半色调屏幕之间,将屏幕矢量wa2,wb2布置为彼此匹配,而其他屏幕向量被布置为不彼此匹配。 半色调屏幕是屏幕向量wa2垂直于基矢量ra1的正交屏幕。 半色调网屏是屏幕向量wb2垂直于基矢量rb1的非正交屏幕。 当屏幕矢量wa2与屏幕向量wb2相匹配时,对应于屏幕向量wa2和wab2的空间频谱彼此匹配。 由于这样的关系,由于一对空间频谱可以在两种颜色之间相互匹配,所以可以为四种颜色的剩余颜色的空间频谱提供更宽的间隔,这将抑制低频莫尔条纹。

    • Conventional I-form crystals of 5-hydroxy-1-methylhydantoin contain, remaining therein in a considerable amount, the organic solvent used in a purification step. In contrast, in II-form crystals, the amount of the organic solvent remaining therein is smaller than the detection limit. Namely, the II-form crystals contain substantially no residual organic solvent. The novel II-form crystals of 5-hydroxy-1-methylhydantoin obtained through recrystallization from water not only contain substantially no residual organic solvent, but also have a high bulk density and are hence advantageous for pharmaceutical preparation. They further have properties advantageous for production, such as low adhesion. The crystals are significantly useful as a material for medicines required to have high safety, such as drugs for renal insufficiency.
