  • Patent number: 11981529
    Abstract: A medium processing apparatus includes a conveyor, a liquid applier, and a crimper. The conveyor conveys a medium. The liquid applier applies liquid to a part of the medium conveyed by the conveyor. The medium is at least one medium. The crimper presses and deforms a bundle of media including the medium to which the liquid is applied by the liquid applier, to bind the bundle of media. The liquid applier includes a liquid application member and a retained liquid amount detector. The liquid application member applies the liquid to a position to be bound by the crimper on the medium. The retained liquid amount detector detects an amount of the liquid retained by the liquid application member.

  • Patent number: 8630021
    Abstract: A color value of output color reproduced based on an output signal value corresponding to an input color value of a grid point in an input color space, which is obtained by sampling a range of the output signal value, are estimated. An evaluation value that evaluates tonality between a color value estimated in correspondence with an input color value of a grid point of interest in the input color space and color values estimated in correspondence with input color values of grid points adjacent to the grid point of interest is calculated. When the input color value of the grid point of interest, whose evaluation value is less than a predetermined threshold value, is obtained, an output signal value corresponding to that input signal value is set in the grid point of interest.

  • Patent number: 8355173
    Abstract: The number of color patches is reduced to attain high-precision color estimation. Hence, the colorimetric values of a plurality of color patches of at least one primary color output by an output device are input. Based on the colorimetric value of first color patches corresponding to a part of the plurality of color patches, colorimetric values corresponding to second color patches other than the first color patches of the plurality of color patches are estimated. Errors between the input colorimetric values of the second color patches and the estimated colorimetric values corresponding to the second color patches are calculated. A plurality of color patches corresponding to the output device is determined based on the calculated errors.
