摘要： In reading out an original image divided into a plurality of regions, a scanner reads out image data having each divided region partially repeated for each adjacent divided region. The read out image data of each divided region is stored in a memory in correspondence with the original image and stored in a memory. A controller identifies an overlapping region of the stored image data, and joins each image data according to the identified result to generate an image data corresponding to the original image.

摘要： An additional data useful for the management of copies of a document for an image forming apparatus is embedded in a hard copy of the document. The additional data is embedded in an inherent image of a document as discrete dots arranged in a prescribed format. Preferably, the size of each of said discrete dots is not so large as to be recognized easily with naked eyes. The additional data can be embedded in unit of blocks. Further, the density of the discrete dots is different from the density adjacent to the discrete dots. The image data for embedding an additional data can be obtained by reading a document, or by receiving data sent from a computer or read from a floppy disk. An additional data embedded in a hard copy can be extracted from the image data on the hard copy. Further, the production of a copy according to the image data can be controlled according to the extracted additional data. For example, if the additional data means that the source of the hard copy is a secret document, the copying is allowed only for a legitimate user. An additional data is generated for each copy according to the extracted additional data for embedding it in a hard copy to identify each copy. The additional data generated for each copy are compiled and they are used to manage copies of various sources systematically and illegal copies can be traced easily. If the additional data received from a printer is not consistent with the additional data already stored, the printing may be prohibited. A transmitter for transmitting an additional data may be provided in a document such as a book.

摘要： A device having a periodic wiring structure and a test device therefore which can be fabricated at low cost and is capable of instantaneously determining whether the periodic wiring structure has been fabricated in a physically and electrically correct manner and whether particle obstacles are present. The bit lines of the device to be tested are simultaneously connected to a current source by a column decoder and a bit line connection circuit to generate magnetic force lines in a periodic distribution pattern from the currents flowing in all the bit lines. The generated magnetic force lines are sampled and detected by a one-dimensional Hall element array moved by an actuator. A spatial frequency spectrum of the periodic distribution pattern of the magnetic force lines detected by the one-dimensional Hall element array is by obtained and is collated with a spatial frequency spectrum of a reference distribution pattern.

摘要： In a shadow process mode, a scanner reads out an original with a first exposure lamp in a first scanning operation. The readout image data is stored in an image memory via an I/O control unit. In the second scanning operation, the scanner reads out the original with a second exposure lamp having an illumination direction different from that of the first exposure lamp. The image data read out in the second scanning operation and the data stored in the image memory are subtracted for each pixel by a subtractor. The difference thereof is compared with a predetermined value in a comparator. The compared result is output to a selector, whereby a desired image data is provided to a printer processing unit via the I/O control unit.

摘要： Image data of an original image in a prescribed pixel matrix is subjected to edge emphasis. On the other hand, a maximum and a minimum of the image data are detected. Then, values of the image data subjected to edge emphasis are limited between the maximum and the minimum to provide output data. Thus, edge emphasis can be performed without increasing noises even for hand-written characters of low densities.

摘要： An image processing apparatus capable of contracting or enlarging an original image includes a variable scale magnification processing unit for magnifying the original image in accordance with a magnification m, and a digital filter for correcting an image quality. Since weighting matrixes h1-h5 of the digital filter are varied depending on magnification m, a deterioration in image quality can be prevented irrespectively of magnifications.
