摘要:
A storage control apparatus is coupled to a central processing unit (CPU) and a storage unit to control input/output of data between the CPU and the storage unit. The storage control apparatus has at least two processors coupled to the CPU and the storage unit, a cashe 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 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.

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.

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.

An image data rotating apparatus has an n.times.n dot matrix memory which temporarily stores n.times.n dots of image data supplied from a first image data memory. A row/column selector selects one row or column of the n.times.n dot matrix memory in response to a rotation indicating signal, which selects an integer times 90.degree. as a rotating degree, for example, 0.degree., 90.degree., 180.degree., 270.degree. or the like. The n dots of image data stored in the selected row or colum are re-written by outputting the stored data into a second image data memory, and by inputting another n dots of image data from the first image data memory in the same cycle, and with the repeating of this cycle, all the n.times.n dots of image data stored in the n.times.n dot matrix memory are re-written so that the rotated image data can be retrieved from the second image data memory.

A half tone display apparatus using a display apparatus of bilevel representation in white and black is provided. The apparatus includes a unit supplied with a multilevel image such as a color image, a device for detecting edges in characters, patterns and photographic images, a unit for deriving a level difference between pixels adjacent to the edge, and a control unit for forcibly displaying a pixel of the edge portion as a white or black pixel for emphasis provided that the level difference is not larger than a predetermined threshold and for applying dither conversion to other pixels.
