摘要:
An image processing apparatus is provided which can output an image from which only specific image information can be positively detected when the specific image information used to prohibit copying of image information is added to image data. The present invention includes a specific image information adding portion that adds specific image information representing a specific image to image data when image processing is performed for input image data and a specific image information setting portion that sets a color and/or number of the specific image information.

The present invention provides an image processing apparatus including: an image reading section for reading a document image; a particular image determining section for determining whether or not a particular image is included in image data read by the image reading section; an image processing section for processing the image data; and a resolution converting section for changing a resolution of the image data to be transferred to the particular image determining section, wherein the resolution converting section lowers a pixel frequency of the image data to be transmitted to the particular image determining section so as to perform simple processing. The lowered pixel frequency slows down processing speed of the image data and thereby improves determination accuracy.

An image processing apparatus is provided that can make judgment of a specific pattern accurate and easy and can judge a copying-prohibited original document regardless of the color of the original document and inputted image information of the copying-prohibited original document added with the specific pattern and even when the size of the specific pattern differs. A black detecting color filter executes a binarizing process to inputted image data in terms of black, and a yellow detecting color filter executes a binarizing process to inputted image data in terms of yellow. The black and yellow primitive pattern detecting portions respectively detect black primitive patterns and yellow primitive patterns from the black and yellow binarized image data. The copying-prohibiting added pattern detecting portion detects a specific pattern based on an arrangement of the primitive patterns detected by the black and yellow primitive pattern detecting portions.

An image detecting method is provided that permits the specific image information to be present within image data of a document and is capable of detecting the specific image information within a relatively short period of time and accurately, with little effect of interference with the image data of the document and without regard to an angle at which the document is placed. The specific pattern image comprises a plurality of dot images Sa and Sb arranged in a straight line, and by positioning one of the plurality of dot images Sa and Sb at the center O of a plurality of concentric circles of different diameters and detecting that other dot images are on the plurality of concentric circles R1 to R4 and are on a straight line L running through the center O of the concentric circles, the pattern image is detected.

Depending on processing to be executed, the processing is prevented from being restricted even if a particular image is included in image data. There is provided an image processing apparatus comprising an authentication section 67 which distinguishes a user; a particular-image judgment section 63 which detects particular images from inputted image data and judges whether or not the number of the particular images exceeds a threshold; and a threshold determination section 66 which determines a threshold according to the user and processing to be executed; and a control section 7 which restricts the processing to be executed when the number of the particular images exceeds the threshold. Depending on the importance degree of the security of the processing to be executed, the threshold determination section 66 lowers the threshold as the importance degree is higher and raises the threshold as the importance degree is lower. Furthermore, the threshold is raised in the case of a registered user and lowered in the case of an unregistered user.
摘要:
The image processing apparatus (data processing apparatus) stores data in a storing unit (storing means), inputs and outputs the data to and from the storing unit via a storage control unit (input-output means) and processes the data outputted from the storing unit with a control unit (processing means). The storage control unit inputs and outputs image data to and from the storing unit by the DMA method through a path via a DMA control unit and inputs and outputs other data such as a control instruction to and from the storing unit by the PIO method through a path via a PIO control unit. Image data to be inputted and outputted to and from the storing unit by the DMA method is encrypted in an input operation and decrypted in an output operation by an encryption/decryption unit provided on the input-output path for DMA method.
摘要:
An image processing apparatus in which a specific image including regulation information and a specific image including trace information are attached so that the specific images are different from each other is provided. An image processing apparatus 1 of the present invention is provided with an image reading section 210, an image forming section 220, an image storage section 400, an operation section 240 and a control section 300, in a cabinet 2. The control section 300 is provided with a first specific image adding section 311, a second specific image adding section 308, a determination section 312, an altering section 313 and a CPU 301. The determination section 312 compares a first specific image A and a second specific image B which have been generated. When it has been determined that a part of the second specific image B is the first specific image A, the altering section 313 alters the second specific image B. The second specific image adding section 308 adds the altered second specific image B.
