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： 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.

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： 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： An image processing system wherein for an inputted composite image composed of a line image and a dither image, both a line image processing and a dither image processing are carried out in parallel, and one of the processed results as selected in accordance with the image region discrimination result. The dither image processing is carried out through data conversion for calculating multivalued gray scale image from the inputted image data, gray scale data conversion for adjusting the gray scale image data so as to match an output device and obtaining such adjusted gray scale image data, and re-binarization for re-binarizing the gray scale image data after subjected to the gray scale conversion. The image region discrimination for discriminating if an image region is of a line image of a dither image is carried out based on a ratio of the number of black or white pixels within the region to the contour line length within the range. In ordered dither image through a screened type dither matrix is discriminated in accordance with a correlation between adjacent pixel trains each having a predetermined number of pixels.

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.
