Publication number: 20100079820Abstract: A color image forming apparatus of a so-called tandem type which has image forming units in correspondence with colors is provided. In the color image forming apparatus, a color discrepancy amount storage unit stores information of a color discrepancy amount of each of the image forming units, which is measured in advance. A first color discrepancy correcting unit performs color discrepancy correction in a pixel unit by performing coordinate conversion of bitmap data to be printed based on the information of the color discrepancy amount stored in the color discrepancy amount storage unit. A second color discrepancy correcting unit performs color discrepancy correction in less than a pixel unit by performing tone correction of the bitmap data corrected by the first color discrepancy correcting unit based on the information of the color discrepancy amount stored in the color discrepancy amount storage unit.Type: ApplicationFiled: October 21, 2009Publication date: April 1, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Kenzo Tojima, Hiroki Kitamura, Yoshiyuki Akiba, Tsutomu Takata, Shuichi Nakamura, Yusuke Yamamoto, Masanao Motoyama, Takeshi Akiyama, Takaaki Nagaoka

Patent number: 7684079Abstract: An image forming engine has color shifting amount storage units C, M, Y, and K (black) which store actual shifting amounts relative to ideal scan directions on image carriers C, M, Y, and K in image forming units C, M, Y, and K. Color shifting correction amount arithmetic units calculate color shifting correction amounts for respective color components to base on the stored color shifting amounts. Color shifting correction units C, M, Y, and K perform color shifting correction by converting coordinates upon reading out image data from bitmap memories C, M, Y, and K on the basis of the calculated color shifting correction amounts, and then perform tone correction. Data after tone correction undergo halftone processing by halftone processors. C, M, Y, and K to suppress moire. PWM processors C, M, Y, and K generate PWM signals for scanning, and output them to exposure units C, M, Y, and K of the respective image forming units.Type: GrantFiled: November 16, 2005Date of Patent: March 23, 2010Assignee: Canon Kabushiki KaishaInventors: Tsutomu Takata, Hiroki Kitamura, Yoshiyuki Akiba, Shuichi Nakamura, Yusuke Yamamoto, Masanao Motoyama, Takeshi Akiyama, Kenzo Tojima, Takaaki Nagaoka
