  • Publication number: 20120188387
    Abstract: According to one embodiment, a camera module includes an image stabilization section and a superposing section. The image stabilization section adjusts a position of a correction lens such that a second image, which is obtained in succession to a first image, is moved by a movement less than a length of one pixel relative to the first image. The superposing section superposes the first image and one or more of the second images that are taken after the position of the correction lens has been adjusted by the image stabilization section.

  • Patent number: 8149456
    Abstract: Restriction information on a total colorant amount for a medium is obtained. Patches at grid points in a color space corresponding to a plurality of colorants at which the total colorant amount falls within a restriction represented by the restriction information, and a patch at a point surrounded by the patches are generated. Color values are obtained by measuring the colors of the patches printed on the medium. It is determined based on a color prediction value between the grid points whether the measured color values are appropriate, and if so, a color value at a grid point at which the total colorant amount exceeds the restriction is estimated based on the measured color values. A color separation table is created based on the measured color values and the estimated value.

  • Patent number: 8147019
    Abstract: By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation.

  • Patent number: 7588306
    Abstract: A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle around (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle around (2)} and {circle around (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.
