Abstract: Predetermined additional information is superposed as a dot pattern on image information read by an image scanner, and the image information superposed with the additional information is modulated. The modulated information is demodulated and recorded on a recording medium to perform a series of operations, i.e., to simultaneously satisfy both pattern addition and modulation/demodulation.

Abstract: A system is constructed by connecting a plurality of digital copying machines (stations). having a common structure, and a master station 1001 and slave stations 1002 to 1004 are defined in accordance with their addresses. The master station 1001 issues a status request command to the slave stations at a predetermined time interval in order to gather information on the status of each slave station. The status which can be used in the system are recognized, depending upon the information, and a user selects the station or stations to be used. One of the station is made to read an original image, and the image is printed by the selected station or stations. The above constructed image processing system results in good expandability.

Abstract: An image processing apparatus capable of displaying a preview image which has close resemblance to an original image or an edited image automatically applies image processes, such as magnification/compression, rotation, and displacement, to the preview image on the basis of the size of an image and the size of a display screen. Image size information and a reference position mark are displayed after being synthesized. A preview image is thus displayed which may easily be checked by an operator.

Abstract: An image processor matches a hue of an output image with a hue of a preview image. The image processor generates preview image data to confirm on a display, an output color image generated by an image forming unit. The image processor incudes an input unit which inputs from the image forming unit density data representative of the output color image, the density data depending on the output characteristics of the image forming unit. A conversion unit converts the input density data into luminance data in a predetermined color space, and a color correction unit corrects color of the luminance data in accordance with the display characteristics and observation conditions of the display. The preview image data is generated dependent on the type of display and color temperature of the display.
