摘要： Two or more original illumination units are mounted on an image reading apparatus. In reading a patched original, an image read while being illuminated along one direction is compared with an image read while being illuminated along another direction or along two directions including the one direction and another direction. In accordance with an image data difference between the two images, image processing or illumination light amount changing is performed to erase shades to be caused by a patched portion of the original.

摘要： A color image processing method and apparatus in which reproducibility of gray color is improved. UCR processing and black color density extraction processing are performed so as to compensate homogeneity of gray color by changing the setting of UCR and black color toner/ink amount in an intermediate density area and high density area. When brightness (RGB) image signals are converted into density (YMCBk) image signals, in the masking UCR circuit 406-2, UCR and black color toner/ink amount is increased in the intermediate density area, while UCR is reduced in the high density area. Or UCR and black color toner/ink amount is increased in the intermediate density area and achromatic area of the intermediate density area is expressed only by the black component, while the UCR is reduced in the high density area. Corresponding density image signals are thus converted.

摘要： In a copying machine connected to the network, calibrations on the printers are performed as follows. When an execution of calibration is requested, the copying machine displays all identification numbers of the printers connected to the network on the operation panel of the copying machine. When the user selects a printer to be calibrated through the display, the copying machine causes the selected printer to output a specified test pattern. Then the copying machine reads the test pattern, generates a correction table and registers the generated table with the printer.

摘要： A color image reading system in which an input color image signal is converted into color data signals. The color data signals are indicative of a combination of data of reference stimuli represented by vertices of a triangle of which one side circumscribes a pure purple locus, and of which the remaining two sides circumscribes two points of a spectral locus of a color degree diagram, the two points representing substantially middle colors between a color represented by one vertex of the triangle at which the remaining two sides intersect and each of two colors represented by the remaining two sides of the triangle, respectively. The input color image signal is reproduced on a color image output device in response to the provision of the color data signals.
