  • Patent number: 7274471
    Abstract: A system and method of measuring a distance of semiconductor patterns is provided. The system includes a microscope and a control unit. The control unit calculates standard coordinates of standard points in view-fields that include spots, spot coordinates of spots with respect to standard points, real coordinates of spots from both of the standard coordinates and spot coordinates, and finally the distance between the two spots from the first and second real coordinates. Coordinates are determined using high magnification, in conjunction with pixel counting, allowing more precise distance measurements.

  • Patent number: 7274491
    Abstract: Upon outputting halftone image data to an output device, density transformation is prevalently done to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct any color fog and the like of a photo image. Hence, lightness/color difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness/color difference transform amount of the halftone image data is set on the basis of the acquired lightness/color difference information.

  • Patent number: 7274492
    Abstract: This invention is a method of producing a set of TRC's for a color printer's secondary halftone screens that is correlated with the printer's primary halftone screens. The method makes use of the printer/screen characteristic data that is normally gathered during screen calibration. However, instead of progressing from the data to a normal calibration for the secondary screens, the method goes backward through the data starting with the finished primary screen TRC's. The method insures that for every primary screen density, the closest possible secondary screen density is used when the same digital value is specified.

  • Patent number: 7274493
    Abstract: Where a magnification (enlargement/reduction of image) has been set through operation keys of an operation panel, a main CPU sends information on read magnification to a scanner CPU of a scanner section. In this case, where the magnification is not set in particular, information of 100% magnification is sent to the scanner CPU. Based on a microstep division number of a step angle corresponding to the received information on read magnification, the scanner CPU controls the driving of a scan motor via a scan motor driver.
