  • Image processing system
    Patent number: 4769852
    Abstract: An image processing system has an original reader or an image file for generating an image signal, a soft display, a high-speed printer, a small printer, a work station with a CPU, and a switching device. An image can always be displayed or printed at the center of a display surface or of a recording medium irrespective of a difference in the image and the display surface or recording medium.
    Type: Grant
    Filed: January 16, 1987
    Date of Patent: September 6, 1988
    Assignee: Canon Kabushiki Kaisha

  • Image signal processing apparatus
    Patent number: 4674126
    Abstract: An image signal processing apparatus has a CCD for reading an image, a peak detector circuit for detecting a peak value of changes in an analog image signal received from the CCD, a slice level memory circuit for storing a fixed slice level, a comparator, and a slice level change circuit for setting a proper slice level for the image signal. Thickening of a character image or the like is prevented, allowing satisfactory readout of a microfilm image.
