Patent number: 7664321Abstract: This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56).Type: GrantFiled: January 27, 2004Date of Patent: February 16, 2010Assignee: Canon Kabushiki KaishaInventors: Shigeo Fukuoka, Hiroshi Tanioka, Akihiro Usami, Ken-Ichi Ohta, Kitahiro Kaneda, Hirohiko Ito, Shinichi Kato, Tomohiro Akiba, Tomotoshi Kanatsu, Reiji Misawa, Yoshihide Terao, Mitsuru Uzawa
