  • Publication number: 20200242387
    Abstract: An information processing apparatus includes a first character recognition section that performs character recognition of an input image on an assumption that a character in the input image belongs to a first character type and outputs a first character recognition result being a result of the character recognition, a second character recognition section that performs character recognition of the input image on an assumption that the character in the input image belongs to a second character type and outputs a second character recognition section being a result of the character recognition, the second character type being a set obtained by adding at least one or more characters which do not belong to the first character type to a set of characters belonging to the first character type, and a matching section that performs matching of the first character recognition result with the second character recognition result, and, in a case where it is found that the first character recognition result does not match w

  • Publication number: 20190385008
    Abstract: An information processing apparatus includes a determination, first, second and third receiving, and first and second checking units, and a controller. When a determination result matches a first determination result, the first checking unit outputs a matching determination result as the final output. The second checking unit checks the first determination result against a second. The first and second determination results are respectively received by the first and second receiving units. When the first determination result matches the second, the second checking unit outputs the matching determination result as the final output. When the input information is received, the controller operates the determination, first receiving, and first checking units. When it is determined that the determination result does not match the first determination result, the controller operates selectively one of a unit set and the third receiving unit. The unit set is constituted by the second receiving and checking units.

  • Patent number: 9390922
    Abstract: Sidewall spacers formed on sides of mandrels are separated by first gaps in a first region and separated by wider second gaps in a second region. The second gaps are filled while a capping layer caps the first gaps. The capping layer is etched thereby exposing mandrels in the first region, which are removed. An underlying layer is patterned using the sidewall spacers separated by first gaps to form word lines in the first region and using sidewall spacers with filled second gaps to form select lines in the second region.

  • Patent number: 8665292
    Abstract: A color gamut boundary information generating device includes a mapping unit, a triangulating unit, and a generating unit. The mapping unit maps boundary points existing at plural coordinates in a color space that is independent of an output device to corresponding points in a two-dimensional region while maintaining respective phases of the boundary points. The triangulating unit performs triangulation on the inside of a convex hull including plural points in the two-dimensional region obtained by the mapping unit, thereby generating triangulation information, which is a result of the triangulation. The generating unit generates color gamut boundary information on the basis of the triangulation information generated by the triangulating unit. The color gamut boundary information is information that specifies a three-dimensional shape in the color space, the three-dimensional shape having a boundary including the boundary points.

  • Patent number: 8045186
    Abstract: An image processing system includes a profile generating section, a designating section, a calculating section and a correcting section. The profile generating section generates a color conversion profile based on first colorimetric values obtained from a first color chart output from a target device and second colorimetric values obtained from a second color chart from an output device other than the target device. The calculating section calculates difference information between a first data value obtained by converting a designated color into a device-independent color space and a second data value obtained by converting the designated color using the color conversion profile into a second color and converting the second color using the device-independent color space. The correcting section corrects the first colorimetric values based on the difference information. The profile generating section generates the color conversion profile again based on the corrected first colorimetric values.
