The storage control apparatus has at least two processors coupled to the CPU and the storage unit, a cache memory (CM) unit for temporarily storing data of the storage unit, a shared memory (SM) unit for storing information concerning control of the CM unit and the storage unit, and a selector coupled to the at least two processors, the CM unit and the SM unit through access paths to selectively apply access requests from the at least two processors to the CM unit and the SM unit.

The present invention provides an image reducing system and method capable of retaining fine lines in a reduced image by reducing an original image and by quickly forming the reduced image with high quality. The method includes specifying positions of pixels of a reduced image in the original image according to reduction ratios, extracting a run of pieces of the same color information about the color of the pixels of the original image as a line, determining the line width of the extracted line and determining the line width after reduction in the reduction ratios based on the line width of the extracted line and calculating the centroid of the extracted line, and retaining the color information about the extracted line at a reduced pixel near the centroid on the basis of the centroid of the extracted line and the line width after reduction. The method further performs the step of determining the color information about each reduced pixel based on the retained color information.

Apparatus and method for image reduction

In an image-data managing apparatus for a work-flow system, wherein image data transmitted from a server are updated sequentially by a plurality of clients, a temporary storage for temporarily storing data being updated is provided in each client, and an image database, an image-data storage device, a work-flow managing unit, and a recovery-state managing unit are provided in the server. When a failure occurs in the image-data managing apparatus and the recovery of image data is requested, the recovery-state managing unit extracts control information from the work-flow managing unit, which control information indicates whether or not image data are preserved in the temporary storage or the image-data storage device in the course of update processing, thereby executing a function for identifying image data to be retrieved

Image-data managing apparatus

In the bus constitution in an information processing unit for transferring data between a bus-master and bus-slave via a plurality of buses, if a fault occurs in a bus when data is transferred between the bus-master and bus-slave via the buses and the H side fault detection/reporting circuit of the bus-slave or the H side fault detection/processing circuit of the bus-master detects the fault, the data transfer via the bus is stopped and information indicating that the bus is faulty is stored in the bus status information keeping circuit. When the data transfer via the bus ends normally thereafter, the bus selector confirms that the bus is normal from the information of the bus status information keeping circuit and activates the L side bus controller so as to operate the bus and to transfer the data which cannot be transferred due to the bus fault via the bus.

Multiple bus control method and a system thereof

The present invention is a data file apparatus in which input data files are assigned attribute information which is a clue to retrieval of the data files. Each data file is assigned an appropriate symbol to be displayed when assignment of a symbol as attribute information for the desired first data file displayed in the display means is selected, and each data file is assigned a keyword for when assignment of a keyword as attribute information for the desired second data file is selected. Accordingly data files may be easily registered and retrieved in accordance with attribute information thereof as either symbols or keywords.

Data file apparatus for registering and retrieving data files in

Disclosed herein is a system integrally comprising a CAD system and an electronic filing system. When vector data such as figures and their names are converted to image (raster) data for storage, the system automatically extracts, from the vector data coming from the CAD system, those data that correspond to predetermined character attributes, maximum numeric attributes, primitives of each figure and the topology thereof. The data are set as key-words and are made to correspond to the image data for registration and storage into the electronic filing system. In searching for desired image data, the corresponding key-words are input for data retrieval and output.

Method and system for registering and filing image data

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.

Document information compression and retrieval system and document

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.

Image processing system

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.

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.
