    • 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。

    • There is provided an image processing apparatus for modulating a concentration of input image data, comprising: an inputting device to input image data; an RAM to store first image data input by the inputtng device; a processing unit to execute a modulating process to at least one area such as a non-rectangular area in second image data input by the inputting device by using the first image data stored in the RAM; and a detector to detect a predetermined color of the second image data. The area is specified by the color detected by the detector. The inputting device includes a CCD for reading an original and generating RGB color component signals. With this apparatus, a texture process is executed to at least one non-rectangular area and the result can be output in a real-time manner.
    • 提供了一种用于调制输入图像数据的浓度的图像处理装置,包括:输入图像数据的输入装置; RAM,用于存储由输入装置输入的第一图像数据; 处理单元,用于通过使用存储在RAM中的第一图像数据对由输入设备输入的第二图像数据中的至少一个区域(诸如非矩形区域)执行调制处理; 以及检测器,用于检测第二图像数据的预定颜色。 该区域由检测器检测到的颜色指定。 输入装置包括用于读取原稿并生成RGB颜色分量信号的CCD。 利用该装置,对至少一个非矩形区域执行纹理处理,并且可以以实时方式输出结果。
