摘要： An image processing device includes a storage unit which stores both image data input from a reading unit and relevant information of the image data, a first image-data-processing unit which processes both the image data input from the reading unit and image data output to a writing unit, and a second image-data-processing unit which is detachably attached to the first image-data-processing unit, has an image recognition function, and processes the image data input from the reading unit. The first image-data-processing unit includes a recognition unit recognizing the input image data, an image processing unit performing image processing based on a result of the recognition by the recognition unit, and a determining unit determining whether operation of the second image-data-processing unit is normal.

摘要： A method and apparatus for preventing or inhibiting effective reproduction of documents such as currency, checks, stock certificates, and any other printed document including a pre-defined security mark printed therein. The method and apparatus operate to effect a multi-step review of all digital image data acquired from a printed document to be reproduced for purposes of locating any potential security marks and further examining same for purposes of positively identifying a potential security mark as an actual security mark. If a mark is located and verified to be an authentic security mark, effective reproduction of the printed document will not be permitted and/or other security measures will be taken. Processing speed is improved by using run profile analysis to limit the image features that are subjected to computationally intensive template matching operations. Run profiles are tracked using a finite automaton.

摘要： A printer (30) prints image data received from a personal computer (20). The printer stores a recognition program, which is installed for the printer driver of the personal computer. The personal computer executes the received recognition program to carry out recognition. Upon detecting a specific image, the personal computer instructs the printer to discontinue the printing operation. An image processing system is thus provided which prohibits the printer from producing printout if the personal computer connected with the printer detects a prohibited image.

摘要： A computer generates a print ID based on input image data on which a forgery preventing process is performed, and transfers the print ID to a printer. The printer generates a common key corresponding to the print ID, and transfers it to the computer. The computer encrypts the image data using a common key, represents it as a print control command, and transfers the data with the print ID to the printer. The printer analyzes the command of the print control data, extracts the encrypted print image data, decrypts the data using the common key, and stores the decrypted print image data in a storage medium, thereby preventing the data from being printed on a number of unspecified printers.

摘要： A copying machine acquires image data in units of a belt-like area by means of a reading unit (10), converts the image data into YMCK data by means of an image processing unit (20) of the next stage, zooms the YMCK data by means of a zooming section (22), and generates binarized YMCK data by means of a pseudo-gradation processing section (24). The output section (30) of the copying machine successively prints the image data in units of a belt-like area based on the binarized data. The output of the image processing unit (20) is divided into data blocks of 64 dots for a reducing process (data blocks of 128 dots for a unity magnification or magnification process). Therefore, the output of the unit (20) is given to a recognizing device (50) and the device (50) recognizes the output based on the data generated after changing the magnification. As a result, even such a copying machine which print image data on each prescribed area while the machine is reading the image data in units of a belt-like area smaller than the whole area of an original detect image data containing a specific image (specific pattern).

摘要： In steganographically encoding a host image to secretly convey plural bits of auxiliary data, changes are made to the image that are manifested in a transform domain as a characteristic pattern. When the image is distorted, such as by rotation or scaling, the characteristic pattern undergoes a corresponding transformation. By noting how the transform domain pattern has been distorted, distortion of the host image can thereby be determined.
摘要翻译：在对主体图像进行隐写编码以隐藏地传送多个辅助数据位的情况下，对在变换域中显示的图像作为特征图案进行改变。当图像失真时，例如通过旋转或缩放，特征图案经历相应的变换。通过注意变换域模式如何被失真，由此可以确定主图像的失真。
