Patent number: 8605321Abstract: A printer control processing device manages a result of the image capturing of the symbol pattern indicating information based on which a print process is controlled. The printer control processing device includes: a recording/retrieving section for obtaining reference pattern data and pattern printing data from an information storage section; a matching level determining section for determining a matching level between reference pattern data and the result of the image capturing by an image capturing device of a symbol pattern printed based on the pattern printing data; and a pattern modifying section modifying the pattern printing data corresponding to a captured symbol pattern if the matching level determining section determines that the matching level is less than a predetermined threshold. Therefore, pattern printing data can be provided which results in a reliably identifiable symbol pattern in the result the image capturing by the image capturing device.Type: GrantFiled: December 6, 2005Date of Patent: December 10, 2013Assignee: Sharp Kabushiki KaishaInventors: Yoshiyuki Nakai, Yohichi Shimazawa

Patent number: 8035864Abstract: Depending on processing to be executed, the processing is prevented from being restricted even if a particular image is included in image data. There is provided an image processing apparatus comprising an authentication section 67 which distinguishes a user; a particular-image judgment section 63 which detects particular images from inputted image data and judges whether or not the number of the particular images exceeds a threshold; and a threshold determination section 66 which determines a threshold according to the user and processing to be executed; and a control section 7 which restricts the processing to be executed when the number of the particular images exceeds the threshold. Depending on the importance degree of the security of the processing to be executed, the threshold determination section 66 lowers the threshold as the importance degree is higher and raises the threshold as the importance degree is lower.Type: GrantFiled: September 19, 2007Date of Patent: October 11, 2011Assignee: Sharp Kabushiki KaishaInventors: Yoshiyuki Nakai, Yohichi Shimazawa, Koichi Sumida

Patent number: 7952732Abstract: A digital multi-function peripheral appends, according to the predetermined specific image information appending conditions, the image data which meets the appending conditions with the specific image information in a form which is set in accordance with the appending conditions when image data which is read at an image reading portion or image data which is externally entered via a FAX modem or communication portion is used for image formation at a printing portion. It is set so that the specific image information is appended to high secrecy image data. When trying to copy the printed image in which the specific image information is embedded, the copy machine which has detected the specific image information will not output the copied image or output a copy sheet having thereon characters such as “Copy Prohibited”.Type: GrantFiled: June 13, 2006Date of Patent: May 31, 2011Assignee: Sharp Kabushiki KaishaInventor: Yohichi Shimazawa

Publication number: 20060222380Abstract: Copy discouraging information which is used for prohibiting or discouraging copying of image information is formed so that it can be positively recognized by a copy machine. The copy discouraging information which is used for prohibiting or discouraging copying is printed so that the number, position and shape of the items of the copy discouraging information are made different depending upon the importance degree of the image information to be printed. If the image information has, for example, a relatively higher importance degree, a plurality of items of the copy discouraging information are printed in the inner sides and in the vicinity of four sides of recording paper. When someone tries to copy this recording paper by the copy machine, presence of the copy discouraging information can be immediately recognized in the copy machine regardless of the scanning direction.Type: ApplicationFiled: March 30, 2006Publication date: October 5, 2006Applicant: Sharp Kabushiki KaishaInventors: Yohichi Shimazawa, Syoichiro Yoshiura, Tsutomu Yoshimoto
