    摘要: An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

    摘要: The present invention is intended to provide an image processing apparatus capable of two-color output representation in high accuracy even with a full-colored original. A color original is entered by an input means for prescan, a density distribution with respect to a hue is obtained for each electric signal of color image information, and a characteristic point of the color original image is obtained from the result of the density distribution. The two-color separation means separates a full-colored original to two colors free from the same color representation according to the information of the characteristic point obtained.

    摘要: A two-color separating circuit separates an input image signal into two color signals R and K. In conformity with a color signal indicating the maximum value of the separated color signals, a color-mixture correcting circuit corrects the other color signal. The density of the color pixel formed by the corrected color signal is predicted, and the difference between the result of prediction and the color signal before correction is distributed among pixels of the same color surrounding this pixel. Accordingly, it is possible to provide an image processing apparatus for supplying an image forming apparatus, which collectively forms images of two colors, with an image signal subjected to processing capable of performing excellent color mixing without lowering the density of whichever of the two color-component images is formed last.
