example 1

[0018] figure 1 is a block diagram showing the configuration of an MFP 3001 as an example of the image forming apparatus in this embodiment.

[0019] The control unit 1 controls each component of the MFP 3001 . The operation unit 5 is a user interface for receiving operations / inputs from a user. User authentication section 6 organizes user authentication of users who use MFP 3001 . The reading section 2 scans a printed document to form document information. The reading section 2 also extracts the code image area contained in the document information and stores it in the memory 7 . The information forming section 3 converts the code image included in the document information into information, thereby obtaining embedded information. The on-line sensor section 4 decodes the embedded information, thereby obtaining copy prohibition information as on-line information.

Abstract

The invention provides an image forming device and an image forming method. Another code image is added so that a code image previously embedded in an original document image can be read. An image forming device includes: a generation means configured to use, when a second code image is combined with the original document image including a first code image, a result of decoding of the first code image to generate a third code image; and means configured to combine the second code image with the original document image and combine the third code image on the second code image.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method. Background technique [0002] Conventionally, there is known a technique of adding a code image such as a barcode to an image manuscript and printing it (for example, Japanese Patent Laid-Open No. 2008-205540). [0003] However, in a device that prints by adding a code image at the time of printing, when scanning a document image in which other code images are embedded in advance and adding a code image to the scanned image, the code image embedded in the document in advance cannot be read in some cases. Image of code in image. Contents of the invention [0004] The present invention provides an image forming apparatus and an image forming method that add another code image to enable reading of a code image pre-embedded in a document image. [0005] An image forming apparatus according to an aspect of the present invention includes: a determination unit configu...
