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： 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 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.

摘要： A document is scanned by an optical scanner to be converted into digital image data to be transmitted to an image memory. Characters are extracted from the digital image data one by one and features are extracted from each of the extracted characters. The features as standard patterns stored in a character recognition dictionary are read out to be subjected to 90 degree rotation, 180 degree rotation and 270 degree rotation by a feature rotator, thereby to produce standard patterns of the four directions. Similarity measures are individually calculated between the standard patterns of the four directions and the features of each extracted character, with respect to the four directions. This processing is repeated for a plurality of characters recorded in the document to select a direction having the maximum add value of the similarity measures, thereby to detect an input direction of the document. When the detected direction is not a proper direction, the counterclockwise rotation is given to the digital image data to correct the digital image data to the proper direction.

摘要： A method of superimposing and displaying a color image expressed by color code data and a color image expressed by three primary color dot data comprises the steps of converting the color code data into three primary color density data while converting the three primary color dot data into density data which are in the same form as the three primary color density data, and selectively displaying one of the two density data for each pixel on a display screen. Thus, two types of color image data, i.e., color code data and three primary color dot data are allowed to be handled in the same way and to be superimposed on a color display. This is useful in a color image filing system based on a workstation. In transferring the two types of color image data to a printer, the two image data are combined in memories and transferred to the printer as dot data through the existing printer interface. At the printer, the combined image data is divided into the previous two types of image data and printed in the same manner as in the display action.
