Patent number: 9239972Abstract: A recording apparatus is capable of forming an image on a recording medium by using a recording head including first and second recording element arrays for one color component wherein each recording element array includes a plurality of recording elements arranged therein. To perform, in a short time, processes including converting of multilevel data to binary data and assigning of the binary data to the recording element arrays, a multilevel data buffer stores multilevel data, a reading unit reads the multilevel data stored in the multilevel data buffer, and a production unit produces binary data from the multilevel data by using a code table including a plurality of code sets depending on a gray level wherein each code set includes codes corresponding to the first and second recording element arrays. A transferring unit transfers the binary data produced by the production unit to corresponding recording element arrays.Type: GrantFiled: December 1, 2010Date of Patent: January 19, 2016Assignee: Canon Kabushiki KaishaInventor: Yusuke Komano

Patent number: 9102164Abstract: A data processing apparatus determines a color range based on a dot counting value of a number of colors smaller than a number of colors subjected to thinning processing. Thus, even if the number of ink colors subjected to the thinning processing is great, a processing load of the determination of the color range can be reduced.Type: GrantFiled: September 5, 2013Date of Patent: August 11, 2015Assignee: Canon Kabushiki KaishaInventor: Yusuke Komano

Patent number: 9064202Abstract: Textures in a printed image are reduced with a configuration that, provided that a matrix made up of a plurality of dot arrangement patterns is treated as a unit, binarizes image data is repeatedly applying such a matrix to the image data. Specifically, when a shift value K=k, a shift process calculates X+kY for the position (X, Y) of each cell in a 4×4 base matrix. The dot arrangement patterns are then shifted overall such that the cell where the value is k from among these values moves to the position (0, 0). The shift process is conducted while setting different shift values for every repeated use of the base matrix. As a result, regular textures are decreased in the case of using a base matrix made up of a gradation value Lv1 on a pixel area.Type: GrantFiled: May 30, 2013Date of Patent: June 23, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Wakako Tanaka, Hirokazu Tanaka, Tetsuya Edamura, Kiichiro Takahashi, Yusuke Komano
