Patent number: 8736909Abstract: According to an aspect of the invention, an image forming apparatus includes an image correction unit and a determination unit. The image correction unit inserts a new pixel between pixels forming image data with a plurality of pixels printed using a plurality of print color materials arranged in a main scanning direction in order to correct the image width in the main scanning direction. The determination unit determines whether or not the image data is specified for print with a dot representing given information superposed. When the determination unit determines that the image data is specified for print with the dot superposed, a prohibition unit included in the image correction unit prohibits insertion of the new pixel into a pixel string of a print color material of a similar color to the print color material for the dot.Type: GrantFiled: May 18, 2010Date of Patent: May 27, 2014Assignee: Fuji Xerox Co., Ltd.Inventors: Noribumi Sato, Mitsuru Iioka, Jun Koyatsu, Kaoru Yamauchi, Keiichi Okada

Patent number: 8699083Abstract: An image processing device includes a screen processing unit and a correction processing unit. The screen processing unit executes screen processing for an image to be processed. The correction processing unit performs correction processing of correcting a distortion of an output image from an original image, based on the amount of the distortion, for (i) the image before the screen processing and (ii) the image after the screen processing. The correction amount relating to the correction processing for the image after the screen processing is a small value as compared with the correction amount relating to the correction processing for the image before the screen processing.Type: GrantFiled: December 14, 2010Date of Patent: April 15, 2014Assignee: Fuji Xerox Co., Ltd.Inventors: Keiichi Okada, Kaoru Yamauchi, Noribumi Sato, Mitsuru Iioka, Jun Koyatsu, Hatsuho Ajima

Patent number: 8265502Abstract: An image forming apparatus includes an alternative printing unit. The alternative printing unit performs alternative printing of a black image by mixing images of color materials of three colors of cyan, yellow, and magenta. The alternative printing unit includes a color material amount control unit that controls amounts of the respective color materials, which form the images of the color materials of the three colors, so as to be smaller than those at a time of normal printing.Type: GrantFiled: August 14, 2009Date of Patent: September 11, 2012Assignee: Fuji Xerox Co., Ltd.Inventors: Noribumi Sato, Mitsuru Iioka, Jun Koyatsu, Kaoru Yamauchi, Takaya Nagasaki
