  • Patent number: 8243348
    Abstract: A scanner-characteristic correcting unit converts read image data into normalized image data. A first image processing unit applies a first image processing on the normalized image data. A color determining unit performs a color determination of the normalized image data. A controller image processing unit that applies a second image processing on the normalized image data is provided in a removable manner. When a B&W plotter unit is connected to an image processing apparatus without the controller image processing unit, the first image processing unit generates binary image data of the image data before a result of the color determination is output.
