Patent number: 9361557Abstract: This invention obtains a high-quality output image in which a jaggy or a disconnection of a thin line hardly stands out. An edge detection unit detects whether the pixel of interest is an edge pixel or a non-edge pixel. A screen processing unit performs screen processing for the pixel of interest to determine the output value of the N-level tone. A calculation unit performs filtering processing having a preset visual sense characteristic for an area including the pixel of interest to calculate the target value of the pixel of interest, and corrects the value of the pixel of interest so as to come close to the target value, thereby determining the output value of the N-level tone. The selector selects, according to the detection result by the edge detection unit, either the result from the calculation unit or that from the screen processing unit.Type: GrantFiled: February 11, 2014Date of Patent: June 7, 2016Assignee: CANON KABUSHIKI KAISHAInventors: Hitoshi Fukamachi, Hideki Kubo, Atsushi Ushiroda

Patent number: 9150012Abstract: Raggedness of thin lines or edges is suppressed to improve straightness. For each of the pixels forming image data, each pixel in the image data is assigned to a printing element for outputting a pixel value of the pixel. A control unit controls printing of the image data by driving the plurality of printing elements by time-division driving in which a different driving timing is set to each printing element according to assignment. The control unit drives the printing elements such that the printing elements included in a printing element array are associated with a plurality of different driving timings and further a plurality of printing element arrays have different orders of driving timings for the respective printing elements in an arrangement direction. Distribution information assigns to the pixel a printing element driven at a reference driving timing or a driving timing close to the reference driving timing.Type: GrantFiled: February 26, 2015Date of Patent: October 6, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Takashi Ochiai, Hitoshi Fukamachi
