Patent number: 7942516Abstract: Provided are an image forming method and image forming apparatus capable of always stably transferring an ink image on an intermediate transfer body to a printing medium and stably obtaining an image with high quality. Formation and drying operation of the image using an inkjet method are repeated a plurality of times to obtain the image on the intermediate transfer body and the thus obtained image is transferred from the intermediate transfer body to a printing medium to form the image. At this time, a capability of the drying operation finally performed among a plurality of times of the drying operations is more lowered than those of all the drying operations except the drying operation finally performed.Type: GrantFiled: November 16, 2009Date of Patent: May 17, 2011Assignee: Canon Kabushiki KaishaInventors: Midori Ohara, Hiroshi Taniuchi

Patent number: 7938531Abstract: Methods and apparatus include a handheld printer manipulated by an operator to print an image on a media. A controller correlates a location of a printhead to the image and causes printing or not. A position sensor provides input to the controller. Its signal typifies pixels in a matrix frame indicating a current position frame and, over time, a previous position frame. The controller compares the two frames to find a presence of the previous in the current. To improve computational efficiency, the controller reduces a relative size of both frames before comparing. Specific reduction techniques contemplate converting a matrix frame of pixels indicative of previous and current locations into smaller matrices, including one-dimensional forms. Possible search areas within the current frame to look for the previous frame utilize knowledge about the movement history of the printer. Position sensor signal validity and controller architectures are other noteworthy features.Type: GrantFiled: December 18, 2006Date of Patent: May 10, 2011Assignee: Lexmark International, Inc.Inventors: Michelin de la Peña Grandeza, Vincent Peter Crisostomo Valentus, William Henry Reed
