  • Publication number: 20100172229
    Abstract: In a drawing method and device, an electron beam is radiated to a surface of an object to draw a pattern along scan lines on the surface of the object. A pattern is drawn along the scan lines on the surface of the object by the electron beam through relative movement of the object relative to the electron beam. The electron beam is deflected at a speed that does not cause a pattern to be formed on the object surface, in one of a first direction intersecting the scan lines and a second direction opposite to the first direction, without performing blanking of the electron beam, so that a beam spot of the deflected electron beam is positioned to one of the scan lines on the object surface. The drawing step and the deflecting step are repeated alternately.

  • Patent number: 6064396
    Abstract: The current methods and systems for correcting image information improve input and output characteristics. Although .gamma. correction curves have been used in prior art, the current invention allows more refined control in the correction process without additional parameters or hardware. The refined control includes adjustments at a localized area of the correction curve, an efficient conversion between a standard range value and a device-dependent value, a color-specific correction and a flexible user interface. Furthermore, the above described advantages are provided on demand rather than storing the pre-calculated information.

  • Patent number: 5642439
    Abstract: A digital image processing method includes first through fifth steps. The first step is providing a first matrix pattern having a plurality of threshold values stored in a storage memory. The second step is defining a size of each of second matrix patterns based on a predetermined area of the first matrix pattern. The first matrix pattern is composed of the second matrix patterns each of which includes a partial set of the threshold values and has the defined size so that a line density of an output image is determined. The third step is reading two or more threshold values of one of a plurality of basic matrix patterns from the storage memory at specified addresses. Each second matrix pattern is composed of the basic matrix patterns each of which has two or more threshold values and corresponds to one pixel. The fourth step is comparing the digital image data relating to one pixel with the threshold values of the basic matrix pattern to produce a multilevel image signal based on the comparison result.
