Patent number: 8482805Abstract: An image processing apparatus which can determine the image quality of code data in consideration of the print characteristics of an output device (copying machine or printer) is provided. A code data input unit inputs code data to be added to an image. A print precision data input unit inputs print precision data indicating the print precision of the code data by a printing device. An image quality determination unit determines, based on the code data and the print precision data, the image quality when the printing device prints the code data.Type: GrantFiled: July 12, 2007Date of Patent: July 9, 2013Assignee: Canon Kabushiki KaishaInventor: Akihiro Matsuya

Patent number: 7586641Abstract: A data processing method, which is provided in an image processing system in which a server and a data processor communicate with each other to perform a predetermined data process, includes a step of extracting a feature amount of electronic data to be output from a printer, a step of transmitting original specifying information including the extracted feature amount and a user ID for discriminating a print requester of the electronic data, to the server, a step of controlling generation of print data to be output to the printer, based on original certification information notified by the server, and a step of causing the printer to print the generated print data and information indicating that the print data corresponds to an original. By this method, a large storage capacity is not required to certify one data, and to keep a secret of the stored electronic data is easy.Type: GrantFiled: February 10, 2004Date of Patent: September 8, 2009Assignee: Canon Kabushiki KaishaInventors: Yoichi Takaragi, Kenichi Takahashi, Tatsuo Shinagawa, Akihiro Matsuya, Kunio Yoshihara

Patent number: 7548344Abstract: Two main-scanning-color-group recognition units, each for measuring a degree of continuity of chromatic pixels in a main scanning direction are provided. A degree of continuity in a sub-scanning direction is measured by the degree of continuity of chromatic pixels in the main scanning direction determined by a different threshold.Type: GrantFiled: April 21, 2006Date of Patent: June 16, 2009Assignee: Canon Kabushiki KaishaInventor: Akihiro Matsuya

Patent number: 7546244Abstract: Since an image processing system that can authenticate the originality of digital data adopts an arrangement that does not save and manage digital data in a server, the server scale can be prevented from increasing, and the security can be improved. To this end, in this invention, in an image processing system in which a client and server are connected to be able to communicate with each other, the feature amount and user ID of digital data to be registered are registered in the server, and the digital data is saved in the client in correspondence with the registration number and registration date upon registering the feature amount and user ID.Type: GrantFiled: December 1, 2004Date of Patent: June 9, 2009Assignee: Canon Kabushiki KaishaInventors: Kunio Yoshihara, Yoichi Takaragi, Akihiro Matsuya, Tatsuo Shinagawa

Patent number: 7509060Abstract: A density signal value determination method, an image forming apparatus, and an image processing system are configured to automatically and optimally determine the density of a copy-forgery-inhibited pattern image that includes a latent image and a background image. In a density signal value determination method, a test sheet, on which a plurality of latent image patches and a plurality of background image patches are formed, is outputted. Subsequently, the luminance, the density, and the reflection density of each of the patches are obtained from image data obtained by reading this test sheet. Then, an optimal combination of a latent image patch and a background image patch is selected according to the obtained values. Finally, density signal values used to generate the selected patches are set to generate a latent image and a background image.Type: GrantFiled: March 15, 2006Date of Patent: March 24, 2009Assignee: Canon Kabushiki KaishaInventors: Hiroyuki Yaguchi, Akihiro Matsuya
