    • There are disclosed an image forming apparatus such as a digital copying machine and an image forming method. In the image forming apparatus and method, there are transformed supplied reference color image data into plural sample image data having color tones stepwisely different from each other by multiplying the reference color image data one by one by supplied plural color adjustment coefficients, and then, there are recorded plural sample images corresponding to the plural sample image data on a piece of recording paper. When the operator selects one of the plural sample images, a controller alters the supplied reference color image data into another reference color image data responsive to color adjustment coefficients of the selected one of the plural sample images.
    • 公开了诸如数字复印机和图像形成方法的图像形成装置。 在图像形成装置和方法中,通过将所提供的多个颜色调整系数逐个乘以参考彩色图像数据,将提供的参考彩色图像数据变换为具有逐步不同的色调的多个样本图像数据,然后在那里 在一张记录纸上记录与多个样本图像数据对应的多个样本图像。 当操作者选择多个样本图像中的一个时,控制器响应于多个样本图像中所选择的一个样本图像的颜色调整系数,将提供的参考彩色图像数据改变为另一参考彩色图像数据。

    • An image forming apparatus performs dither processing on image data to form an image subjected to pseudo-halftone processing. The image forming apparatus includes a dither processing unit that performs dither processing on image data, and a dither pattern generation unit that generates a dither matrix for use in the dither processing, in accordance with an output gradation level. The dither matrix has a size of M×N pixels, and has a plurality of halftone dots arranged in a predetermined pattern in accordance with the output gradation level in order to represent a gradation of each color. The plurality of halftone dots are arranged in the dither matrix such that the halftone dots corresponding to at least two colors are substantially identical in color area ratio to each other in the dither matrix irrespective of a relative position with respective to the colors.
    • 图像形成装置对图像数据进行抖动处理以形成经受假半色调处理的图像。 图像形成装置包括对图像数据进行抖动处理的抖动处理单元和根据输出灰度级产生用于抖动处理的抖动矩阵的抖动图案生成单元。 抖动矩阵具有M×N个像素的尺寸,并且具有根据输出灰度等级以预定图案排列的多个半色调点,以便表示每种颜色的灰度。 多个半色调点被布置在抖动矩阵中,使得对应于至少两种颜色的半色调点在抖动矩阵中的颜色面积比基本上相同,而与相对于颜色的相对位置无关。
