摘要： A disclosed dither matrix is used in halftone processing for converting input image data having M input halftone levels into output image data having N (M>N>2) output halftone levels. In the halftone processing, a concentration type dither matrix is used as the dither matrix when an input halftone level is within a range of input halftone levels corresponding to an output halftone level that is lower than a predetermined threshold level T (N>T>1), and a dispersion type dither matrix is used as the dither matrix when the input halftone level is within a range of input halftone levels corresponding to an output halftone level that is equal to or higher than the predetermined threshold level T.
摘要翻译：所公开的抖动矩阵用于将具有M个输入半色调电平的输入图像数据转换成具有N（M> N> 2）个输出半色调电平的输出图像数据的半色调处理。在半色调处理中，当输入半色调电平在与低于预定阈值电平T（N> T> 1）的输出半色调电平相对应的输入半色调电平的范围内时，使用浓度型抖动矩阵作为抖动矩阵），并且当输入半色调电平在与等于或高于预定阈值电平T的输出半色调电平相对应的输入半色调电平的范围内时，使用色散型抖动矩阵作为抖动矩阵。

摘要： An image processing method performs processing to generate image data based on input data and output the image data to an image forming device. The image forming device includes a printing head in which first nozzles for ejecting color ink drops are arranged in a symmetrical formation to forward and backward scanning directions and second nozzles for ejecting black or gray ink drops are arranged in an unsymmetrical formation with respect to the first nozzles. The image forming device is adapted to perform a uni-directional printing or a bidirectional printing with the printing head. In the image processing method, a black generation processing to the input data is performed, and when performing the black generation processing, a black-generation start level for the bidirectional printing is delayed to a shadow-side gradation level from a black-generation start level for the uni-directional printing.

摘要： An image processing method for processing image data to be output by an image forming apparatus is disclosed. The image forming apparatus is configured to form a tone pattern on a recording medium by forming an arrangement of dots on the recording medium. The arrangement of dots is formed on the recording medium by jetting a recording liquid from a recording head while moving the recording head in a main scanning direction a plurality of times and intermittently conveying the recording medium in a sub-scanning direction that perpendicularly intersects the main scanning direction. The method includes the step of generating a mask pattern for moving the recording head in the main scanning direction and forming the dots in an inconsecutive order on the recording medium.
