摘要： To reliably and simply prevent the output of specified image data, a unit to detect a pattern is installed in one of the devices in a system consisting of an image scanner 1, control device 2 (a personal computer) and printer 3 which are connected consecutively. This pattern detection unit contains a unit which detects a specified pattern from the mass of image data representing a document. Once this pattern has been found, either the subsequent image data are altered before being output or output of the image data is interrupted. When the system starts up, the control unit for each device checks whether that device, or one of the other devices in the system, has a pattern detection unit as described above. If it determines that no device has such a unit, it halts operation.

摘要： An non-reproducible image formation preventing apparatus has a recognition section, a storage section and a comparison/determination section. The recognition section performs recognition processing for received image data, determines whether or not the image data is an non-reproducible image, and outputs the determination result to an image formation section. The storage section stores non-reproducible image data recognized as an non-reproducible image by the recognition section. The comparison/determination section compares the non-reproducible image data stored in the storage section with an image based on input image data given through an image process section and finding a match degree therebetween. If either of the comparison/determination section and the recognition section determines that the image is an non-reproducible image, a detection signal is sent to the image formation section for stopping normal print. Since the data is digital data, stored non-reproducible images are also stable and a determination can be made at high speed.
摘要翻译：不可重现的图像形成防止装置具有识别部分，存储部分和比较/确定部分。识别部对接收到的图像数据进行识别处理，判定图像数据是否为不可重现的图像，并将判定结果输出到图像形成部。存储部存储识别部识别为不可重现图像的不可重现图像数据。比较/确定部分基于通过图像处理部分给出的输入图像数据将存储在存储部分中的不可重现的图像数据与图像进行比较，并找到它们之间的匹配度。如果比较/确定部分和识别部分中的任一个确定图像是不可重现的图像，则检测信号被发送到图像形成部分以停止正常打印。由于数据是数字数据，存储的不可重现的图像也是稳定的，并且可以高速进行确定。

摘要： Fluctuation information produced by a fluctuation producing portion (36) is superimposed on given image data by a fluctuation superimposing portion (35). The superimposed image data where the fluctuation information is superimposed is subjected to an image recognition process by an image recognition portion (37). The results of the image recognition are sent to a printer body through a recognition result outputting portion (39). Even if the given image data is the same, fluctuation is superimposed, and therefore the image data on an object to be recognized is altered. As a result, the possibility of a recognition error is suppressed as much as possible.

摘要： A computer (901) has a function of controlling operation of an image recognition unit (201) for counterfeiting prevention in a printer (902). According to this function, a control signal (S1) for instructing operation of the image recognition unit is output to the printer when the type of a command (C1) received from an application (102) is a command type of an image as an object of counterfeiting prevention, while the control signal is not output when the type of the received command is not the command type of an image as an object of counterfeiting prevention. The printer has a function of operating the image recognition unit for image data (D1) applied from the computer only when the control signal is received from the computer. Therefore, in a print system using the computer and the printer equipped with the image recognition unit for counterfeiting prevention, the probability of falsely recognizing even an image irrelevant to counterfeiting to be an image as an object of counterfeiting prevention is lowered, and the printing-out speed is improved as a whole.
摘要翻译：计算机（901）具有在打印机（902）中控制图像识别单元（201）的假冒防止操作的功能。根据该功能，当从应用程序（102）接收的命令（C1）的类型是作为对象的图像的命令类型时，用于指示图像识别单元的操作的控制信号（S1）被输出到打印机当不接收到的命令的类型不是作为防伪对象的图像的命令类型时，不输出控制信号。只有当从计算机接收到控制信号时，打印机具有操作从计算机应用的图像数据（D1）的图像识别单元的功能。因此，在使用计算机的打印系统和装备有用于防伪的图像识别单元的打印机的打印系统中，即使是与作为假冒对象的图像不相关的图像的虚假识别的概率也降低，整体速度得到改善。

摘要： A copying machine obtains image data on the basis of a strip-shaped region by reading portion 10, converts the image data to YMCK data at image processing portion 20 in the succeeding stage, and performs zooming processing at zooming processing portion 22. YMCK binary data is produced by pseudo tone processing portion 24. Output portion 30 sequentially prints out data on the basis of a strip-shaped region based on the produced binary data. The output of the image processing portion is divided into 64 dot portions for a reduction processing (into 128 dot portions for equal size/expansion processing). Then, the output of the image processing portion is applied to a recognizing device 50, which performs recognizing processing based on data after a zooming operation. As a result, any copying machine printing out data for each prescribed region while reading the data on the basis of a strip-shaped region smaller than the entire original may surely detect image data including a particular image (particular pattern).

摘要： An image recognition method and device detects an object mark reliably even when the mark is defaced with a different color. RGB signals are transmitted to color extraction unit. The color extraction unit has a characteristic color extraction block to extract the characteristic color of the object mark. A binary image is generated from the extracted pixels which are the color of the mark and stored in storage device. A mark detection unit detects the location of the mark in the stored image data and an image extraction unit extracts the region where the mark is located and obtains a feature count. A matching unit compares the feature count with a reference pattern and finds the goodness of fit. A control unit subjects the goodness of fit value to threshold value processing to determine whether this is a nonreproducible document. If the mark has been defaced with black ink, the pixels constituting the mark are extracted by a likely color extraction block. A binary image is generated and stored in storage device. Thus, the defaced mark can undergo the same recognition processing as the normal mark, and both can be recognized.

摘要： An image processing portion (1) performs binarization, segmentation, and feature extraction of a received image using a RAM (2), compares the extracted feature with specific pattern data stored in a dictionary data memory (3), performs recognition processing, and provides recognition results to a CPU (4). The dictionary data memory is a volatile memory, in which specific pattern data held by the CPU is written by the CPU when power is turned on. Since the data stored in the volatile memory is erased when power is turned off, the dictionary data memory can be removed and the contents are analyzed when the power is turned off without causing any trouble.
