Problems solved by technology

[0008] However, if such a dot pattern that prohibits the output of image data is added on the entire image data including contents such as text data and photo data, the visibility or appearance of the contents printed on the copy will be weakened (see Figure 14 )
[0009] Regardless of the conditions for reading and outputting image data, if copy prohibition information is not extracted with predetermined accuracy, such a dot pattern is added to image data as prohibition Duplicate information is useless

Embodiment Construction

[0029] Exemplary embodiments of the present invention are explained in detail below with reference to the accompanying drawings.

[0030] In the following embodiments, an image processing apparatus is explained as a multifunction product (MFP) that combines any or all of the functions of, for example, a copier, a facsimile (FAX), a scanner, and a printer. However, the image processing device may be, for example, a facsimile machine, a printer, a personal computer (PC), a game machine, a mobile phone, and a car navigation system.

[0031] The term "content information" as used herein refers to various types of image data content. Said content includes text, character strings, diagrams, illustrations, and photographic images.

[0032] The term "encoding method" used here refers to a method in which each bit of information represented by a bit string is converted into a predetermined pattern and the pattern is added to image data as additional information. The conversion to pat...

Abstract

An image processing apparatus includes an obtaining unit, an area setting unit, and an adding unit. The obtaining unit obtains an adding method by which additional information is to be added to image data containing content information. The area setting unit sets an additional-information area to which the additional information is to be added based on the adding method and the content information. The adding unit adds the additional information to the additional-information area by the adding method.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese priority documents 2007-070882 filed in Japan on March 19, 2007 and 2008-046363 filed in Japan on February 27, 2008, the entire contents of which are incorporated by reference. technical field [0003] The present invention relates to devices, methods and computer products for image processing. Background technique [0004] With the development of image processing techniques in recent years, it has become possible to produce copies that cannot be easily distinguished from the original. In order to prevent the falsification of certain documents such as bank records and marketable bonds, there is a growing need for techniques to prevent duplication and generate perfect copies of these documents. [0005] Under such circumstances, various techniques have been proposed for managing the copying of specific or confidential documents. [0006] For example, Japanese Patent Laid-...
