    摘要: An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.

    摘要: An improved output unit used in recording information on a recording medium is disclosed which comprises a plurality of output parts and in which recording of information is carried out while changing the relative position between the output from the output parts and the recording medium. The improved output unit according to the invention is characterized in that the output parts are arranged in rows in a predetermined direction and are disposed in such a manner that information may be put out selectively from the output parts so as to prevent information from being recorded in overlapping fashion on the recording medium in a manner as often occurs in the conventional unit. Spacing between the output parts is selected large enough that the output parts are easy to manufacture. Since a plurality of output parts can be operated very effectively, extremely high recording efficiency is achieved using the information output unit according to the invention. Also, it is possible to use a recording medium having a relatively low sensitivity and which is generally cheap in cost, for carrying out a high speed recording.

    摘要: A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.

    摘要: A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.

    摘要: A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.
