    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: An image processing apparatus having parallel line conversion circuits for inputting, in parallel, image data for plural lines, line selection circuits for selecting plural sets of image data consisting of image data for at least one line from supplied image data for the plural lines, and sub-scanning interpolation circuits for interpolating each of the selected plural sets of image data.
