摘要： An image filing apparatus and method for receiving as multivalue data an image corresponding to a document, converting the data to binary image data and storing the binary image data. According to the features of the present invention, pixels of that portion of an input image corresponding to a particular color are extracted, and luminance data expressing monochromatic binary image data and binary image data designating colored portions are stored in different planes. Not only black pixels but also pixels expressed in a particular color such as red are described in the plane for the luminance data. Pixels having a particular color to be expressed in "red" such as red characters are extracted and recorded as "1" in another particular color plane, for example, in R-plane different from the luminance plane. The R-plane is recorded with binary image data; only pixels written in "red" are expressed as "1" there and other pixels as "0". When outputted, the pixels in which the contents of the luminance plane are "1" and the contents of the R-plane are "0" are displayed in black and the pixels in which the contents of the R-plane are "1" are displayed in red.

摘要： A file document image input can have shading removed to produce a deshaded image that is useful for highly efficient compression encoding, to be thereafter stored and transmitted in such efficient encoded form. When the image is retrieved or received, the decoded and deshaded image may have shading returned to it by combining with a shaded template image stored in the template image memory or by synthesizing shading in specified regions. By removing shading from regions, optical character recognition, shading identification or other processing such as smear prevention can be enhanced.

摘要： A partial region of an image is set as being a secret region and an ID code is put to data concerning this secret region, the data then being stored in a memory, so that, unless an ID code which is input from a keyboard is coincident with the stored ID code, the image is selectively prevented from being displayed on a CRT display, printed by a printer, or subjected to additional writing, revision, cutting on the display screen. Thus, it is possible to restrict the visual output or revision of secret portions of images and therefore possible to individually control images which need to be kept secret and those which need not.
摘要翻译：将图像的部分区域设置为秘密区域，并将ID代码放入关于该秘密区域的数据，然后将数据存储在存储器中，使得除非从键盘输入的ID代码重合使用存储的ID代码，有选择地防止图像显示在CRT显示器上，由打印机打印，或者在显示屏幕上进行额外的写入，修改，切割。因此，可以限制图像的秘密部分的视觉输出或修改，因此可以单独地控制需要保密的图像和不需要保密的图像。

摘要： A compact character string retrieving system capable of producing correctly the result of matching without omission even upon occurrence of multiple matching in which a plurality of search terms are matched for one character string by a finite automation. A destination state for transition brought about by a trailing character of the search term is newly created instead of an initial state. A transition table storage stores the destination state. On the basis of the source state number and a specified pattern character code, the destination state number is read out from the state transition table storage. When the state number read out represents the destination state of the transition brought about by the trailing character of the specified pattern character string, an identifier thereof is outputted. The identifiers of the search terms matched are each represented by one bit information, and a group of corresponding flags is stored in one slot. Multiple matching can be performed without omission. The character string retrieving system is implemented in a reduced size.

摘要： A document information compression and retrieval system which reduces the document data amount and shortens the retrieval time when mass document information is registered and retrieved. A method of registering document information in a document information retrieval system which stores document information consisting of a large number of characters for retrieval of the stored document information. Entered document information is separated into words. Whether or not each of the words is a word to which a compressed code is assigned is determined. If not already assigned, a compressed code is assigned to the word. The words are converted into the assigned compressed codes for storing a compressed text. At output, retrieval information is accepted and converted into compressed code and stored compressed texts are searched for the compressed text matching the compressed code of the retrieval information, then the words corresponding to the compressed codes are used to expand the compressed text into original document information.

摘要： In an image filing system including an image scanner having at least a color mode and a monochrome mode as image input mode, for inputting document images; a key device for designating the image input mode of the image scanner, an image file for storing document image data inputted from the image scanner and a display screen on which the document images are displayed, a background corresponding to the image input mode is outputted when the document image inputted for the image scanner is displayed on the display screen. If a monochrome document is inputted for processing in a full color or multicolor mode, a monochrome input image and the background which is specific to the full color or the multicolor mode are outputted. Accordingly, a user which looks at the display notices that he or she should change the input mode and inputs the document image again prior to registration of the inputted image in a file.

摘要： Method for determining and correcting the amount of an skew of image which may be read by an image reader, preferably one with with an automatic paper feeding device. Information dependent on the angle of skew of image is obtained in a plurality of the directions with respect to image data and the amount of skew is determined based on the information obtained. Measurement of the information is performed in two or more stages (or steps). At the first stage, the measurement is performed within a narrow range of angles including a reference direction. If no skew angle is detected in the narrow range, then the measurement is performed again at the second stage in a wider range of angles. If a skew angle is detected in the first stage, the second stage is omitted. With the skew angle determined, the image data is rotated in accordance with the skew angle detected to cancel the skew. No correction of the image data is performed if skew angle detection does not result in either the first or the second stage. Preferably, correction of the image data is omitted if the detected skew angle falls within a very small range of angles.
