In a pattern recognition apparatus for recognizing a pattern including a line pattern consisting of a plurality of line segments, there is proposed a line recognition method which comprises steps of: recognizing the coordinates of end points of each of segments constituting a line pattern; employing the coordinates of an end point of a first line segment as base point coordinates; deciding whether the distance between the base point and an end point of a second line segment is less than a certain value or not; employing as a suitable point the end point of the second line segment with said distance being less than the certain value; and selecting a connectable second line segment and connecting said suitable point to the base point of the first line segment.

A line recognition adapted for recognizing a drawing in which a plurality of lines overlapping one another are indicated by a given one of the mutually overlapping lines and overlap symbols representative of the other lines. The overlap symbols are so configured as to give information as to line kinds of the other lines such as solid line, dash line and chain line and/or information as to colors of the other lines. The paths of the other lines are estimated on the basis of the overlap symbols as well as the positions at which they are inserted, for thereby recognizing the whole line paths or patterns of the drawing.

A map display method whereby the contents of a road map displayed can be easily and clearly grasped regardless of the running conditions of a vehicle.In a summarized map displayed on a display screen 10, an area including a vehicle position 11, a destination 13 and a guide route 12 between them is displayed in simplified fashion. At a position far from the destination, as shown in FIG. 2A, a summarized map of a wide area is displayed and objects including a road 14 and a facility 15 are limited to a greater degree. With the approach of the vehicle position 11 to the destination 13, as shown in FIG. 2B, the contraction scale is decreased and a summarized map of a middle area is displayed, while at the same time increasing the objects displayed. With a further approach of the vehicle position 11 to the destination 13, as shown in FIG. 2C, a narrower area is displayed in summarization, while at the same time displaying substantially all the objects, thereby making it possible to grasp the neighborhood of the destination 13 in detail.

In a semiconductor integrated circuit device and a method of designing the same, design information about circuit cells each having a desired function are described as objects according to selected purposes. The pieces of design information are registered in a cell library as cell information capable of forming any of substrate potential fixed cells and substrate potential variable cells. Further, a data sheet common to the substrate potential fixed cell and the substrate potential variable cell is offered to a user, so that the user is able to make a selection according to the user's purposes. The substrate potential fixed cells and the substrate potential variable cells are mixed together on a semiconductor chip so as to be properly used according to the functions or the like of circuit portions in which the cells are used.

Multimedia data in an object structure include entity objects and relation objects, wherein each entity object has data representing a media element as internal data, and each relation object represents a relation between the entity objects. A relation object is searched according to information specified by a search command, and a searched relation object and internal data of an entity object related thereto are displayed on the screen of a display unit as a set of display elements. To generate a digest of the multimedia data, a matching between a structure portion of a user model and a structure portion of a system model is examined. The user model is generated according to a request of the user and arranged in layers, while the system model has been previously generated. The multimedia data are arranged in layers according to the importance of respective data elements constituting the multimedia data. According to an examination result, a user model structure portion is selectively replaced by a system model structure portion, and the replaced user model is adjusted so as to display the same.

A drawing processing system includes file storage equipment for storing drawing data in the form of pages through division of the drawing data, a memory for storing coordinate correcting values for managing pages in a continuated manner, and a temporary memory for storing page data for executing drawing edition processing. The drawing data are transferred from the file storage equipment to the temporary memory in a continuated manner, while the coordinate correcting values being added thereto. A joined drawing is prepared by combining together the pages along the boundaries thereof on the basis of the drawing data as transferred and by erasing the boundaries between the connected pages. Graphic edition processings such as displacement, joining, separation or the like can be then performed in the joined drawing.
摘要:
A domain covering a drawing data subjected to information processing is determined and equally divided into meshes of predetermined smallest size. For each of vectors constituting a drawing data subjected to the processing, the number of the meshes traversed by the vector is counted. When the number of the meshes traversed by a given one of the vectors exceeds a predetermined value, the domain is equally divided into meshes of a larger mesh size and the number of the updated meshes traversed by the given one vector is counted. By repeating this operation, all the vectors are stored in a memory as the drawing information in terms of the mesh size and the coordinates of the meshes traversed by vector. Since the number of the meshes traversed by the vector thus can not exceed the predetermined value, the speeding-up of the drawing information processing can be accomplished. A predetermined value may be provided for the mesh size, if desired. When the mesh size for a given vector exceeds this predetermined value, the coordinates of a rectangle circumscribing the given vector may be stored in the memory as the drawing information.
