  • Patent number: 6091859
    Abstract: Input image data is stored in a register matrix of 7.times.7 in a successive manner. A pattern detecting section detects a black- or white-pixel connective pattern of the reference pixels of a marked pixel. When the reference pixel pattern is a black-pixel connective pattern of 1:n (n=1, 2, 3, . . . ), an enlarging/smoothing processor section interpolates a part of the enlarged marked pixel with black pixels. When it is a white-pixel connective pattern of 1:n (n=1, 2, 3, . . . ), the enlarging/smoothing processor erases a part of the enlarged marked pixel. As a result, the oblique line can be smoothed. The line that is made thick by the smoothing process can be shaped into a thin line. Thus, a high-quality image can be produced.

  • Patent number: 6002592
    Abstract: An semiconductor device and a method for manufacturing semiconductor devices which are easily made compact. A plurality of semiconductor chips having protrusion electrodes respectively provided on a plurality of electrodes formed on circuit surfaces are integrally sealed by an insulating material so as to cover the circuit surfaces while the circuit surfaces are nearly directed to the same direction and arranged in prescribed conditions, and to expose the respective protrusion electrodes; and insulating layers and wiring layers respectively electrically connected to the corresponding protrusion electrodes are alternately laminated on the insulating material so as to have the desired number of layers in the direction of thickness.

  • Patent number: 5798843
    Abstract: An image processing system with a buffer memory for use in a facsimile device. An image processing apparatus comprising an image read unit for operating continuously to read an image on an original document, a buffer memory for temporarily storing image data of the image on the original that is read by the image read unit, a compressing unit for compressing the image data stored in the buffer memory into code data, and a buffer memory controller for controlling the operation of writing the image data into the buffer memory and the operation of reading the image data from the buffer memory. The image data processing device with buffer memory, which can continuously operate an image input terminal and/or an image output terminal, using a buffer memory which has a less number of the memory elements than a page memory.

  • Patent number: 5337156
    Abstract: A facsimile in which various kinds of management reports on its operation conditions are output. In the facsimile, when outputting a management report about the facsimile itself, the contents of the management report are once converted into code data and the code data are then stored in a code storage unit. After that, the stored code data are output from an image recording unit in the same manner as the code data of an image received from outside in the code storage unit is output.
