    • When an magnified and synthesized image is finally printed on a printing medium based on an original image and a character font data, linear magnifying processing is executed with the aid of a software on the host computer side for the original image optically read by a scanner. In addition, vector magnifying processing is executed for font data likewise with the aid of a software, and moreover, synthesizing processing is executed for the font data. At this time, forming processing such as edge emphasizing or the like can be executed after completion of the vector magnifying processing. Synthesizing data are additionally magnified in a printer with the aid of a hardware, and subsequently, the magnified and synthesized image is outputted to the printer for performing a printing operation by the latter. An magnifying rate applicable to the host computer and the printer can be determined such that productivity of the image forming system is maximized.
    • 当基于原始图像和字符字体数据将放大合成图像最终印刷在打印介质上时,借助于主计算机侧的软件执行由扫描仪光学读取的原始图像的线性放大处理。 此外,同样借助于软件对字体数据执行矢量放大处理,此外,对字体数据执行合成处理。 此时,可以在完成矢量放大处理之后执行诸如边缘强调等的形成处理。 借助于硬件,合成数据在打印机中另外放大,随后将放大合成的图像输出到打印机,以进行打印操作。 可以确定适用于主机和打印机的放大率,使得图像形成系统的生产率最大化。

    • In a signal processing apparatus, when a luminance signal in a first numeric range is assigned to an integer value in a second range narrower than a first range representable by predetermined bits, and a luminance signal and color-difference signals are outputted under a predetermined standard in which a color-difference signal in a second numeric range is assigned to an integer value in a third range narrower than the first range, the luminance signal in the first numeric range is assigned to an integer value in a fourth range between the first and second ranges; the color-difference signal in the second numeric range is assigned to an integer value in a fifth range between the first and third ranges; and the fourth range is adjusted in a range between the first range and second range, and the fifth range is adjusted in a range between the first and third ranges.
    • 在信号处理装置中,当在第一数值范围内的亮度信号被分配为比由预定位表示的第一范围窄的第二范围内的整数值时,在预定标准下输出亮度信号和色差信号 其中将第二数值范围内的色差信号分配给比第一范围窄的第三范围内的整数值,将第一数值范围内的亮度信号分配给第一范围和第 第二范围 将第二数值范围中的色差信号分配给第一和第三范围之间的第五范围内的整数值; 并且在第一范围和第二范围之间的范围内调整第四范围,并且在第一和第三范围之间的范围内调整第五范围。
