Publication number: 20080304839Abstract: In an image processing apparatus of the present invention, an image forming section for forming an image makes a part of line information which exists in the image different from other line information. For example, specific information is added by making a part of line information such as a frame line, a ruled line, or an under line, different from other line information. Specific information such as copying inhibition information and user information is added to a document, and thereby it is possible to prevent from affecting other image information different from conventional copying inhibition information and background pattern. Moreover, since the ruled line and the like is formed in black, it is possible to add the specific information or recognize the specific information even in a black-and-white image processing apparatus.Type: ApplicationFiled: May 30, 2008Publication date: December 11, 2008Applicant: Sharp Kabushiki KaishaInventors: Yuji Okamoto, Naofumi Ueda
