    • An image forming apparatus and an electronic device for outputting data to the image forming apparatus. The image forming apparatus comprises an interface for inputting single bit image data and a command from an external device, a first store for storing the single bit image data, a second store for receiving and storing color data for coloring the single bit image data, and an image forming device for forming a color image on the basis of the data in the first and second stores. The electronic device includes a first output for outputting single bit image data, a second output for outputting a color number for one pixel of color image data, and a third output for outputting both first multi-level color component data for the single bit image data and second multi-level color component data for the color number.
    • 一种用于向图像形成装置输出数据的图像形成装置和电子装置。 图像形成装置包括用于输入单位图像数据和来自外部设备的命令的接口,用于存储单个位图像数据的第一存储器,用于接收和存储用于着色单个位图像数据的颜色数据的第二存储器,以及 基于第一和第二存储器中的数据形成彩色图像的图像形成装置。 电子设备包括用于输出单位图像数据的第一输出,用于输出彩色图像数据的一个像素的色数的第二输出和用于输出单位图像数据的第一多级彩色分量数据的第三输出 和用于颜色编号的第二多级颜色分量数据。

    • There is provided a color image processing apparatus in which, by making use of an image reading apparatus of a digital full-color copying apparatus, the designated color to be obtained after conversion is input and stored as component ratio of color-separated image data, and monochromatic image data proportional to the gradation levels, e.g., density, lightness, luminance and so forth are obtained from the color separated image data produced from the original image, the monochromatic image data thus obtained being converted into the color separation data corresponding to the component ratio of the designated color to be obtained after conversion, thereby making it possible to preserve the hue of the designated color and to effect color conversion to the designated color having gradation proportional to the gradation of the original image.
    • 提供了一种彩色图像处理装置,其中,通过利用数字全色复印装置的图像读取装置,输入转换后获得的指定颜色并存储为分色图像数据的分量比, 并且从从原始图像产生的分色图像数据中获得与灰度等级成比例的单色图像数据,例如密度,亮度,亮度等,将由此获得的单色图像数据转换成对应于 在转换之后要获得的指定颜色的分量比,从而使得可以保留指定颜色的色调并且实现对具有与原始图像的灰度成正比的灰度的指定颜色的颜色转换。
