Abstract: A gray scaled data generation device which generates characters and figures of a size which is a fixed number of pixels as gray scaled data, based on outline data which includes outline information which expresses outlines of strokes included in characters and figures and stroke information which shows positions of horizontal and vertical strokes, wherein the gray scaled data generation device has optimizing means for optimizing a position of a stroke, said position being in a coordinate system in which the position is expressed in terms of fine pixels given by dividing every pixel of said size in both a horizontal and a vertical direction, by moving a position of every stroke expressed in the stroke information to a position which satisfies certain criteria related to distances from a border of each pixel; outline generation means for generating outlines in said coordinate system from the outline information, for each stroke which has had its position optimized; and gray scaled data generation means for gene

Abstract: This invention provides improved automated methods and systems for color processing on personal computers whereby an interactive user may intervene to introduce creative and selective choices. Various automatic coloring procedures process coloring. Visual color reproduction is standardized for visual image reproduction using a color gamut matching that of a computer monitor. The color artist may exchange groups of colors automatically en masse. For example, several colors of an image may be changed simultaneously by rotation of hues about a color wheel icon. The system has a novel operating system enriched by abstract notational format and visual shorthand icons. About 600 standardized sample colors proportioned across different color gamuts comprise color standard collections storing recipes for permitting faithful colored image viewing and reproduction of the sample colors on different output devices.

Abstract: A computer animation display system and process for smoothly displaying information containing text and moving picture images is disclosed in which animations are played back smoothly by localizing the area of moving picture display so as to reduce the memory space required on a CD-ROM (Compact Disk Read Only Memory) and allow a greater number of animation frames to be stored on a single CD-ROM. The computer animation display process plays animations on a background bitmap relative to arbitrary screen elements called anchors. The computer animation display process further provides dynamic positioning of animation during playback to maintain alignment between the animation and its corresponding anchor should the anchor's position change. The computer animation display process also provides for dynamic display of independent, separately stored text during animation playback. Modification of the text alone, without the need to modify the underlying animated graphics, is also provided.

The document database management apparatus includes a generating regulation management section for holding a regulation to generate a logical structure of a document in the database from a logical structure of the document to be stored in the database, a document generating section for generating a document in the database from the document to be stored in accordance with the regulation stored in the generating regulation management section, and a document management section for storing a document generated by the document generation section in the database.

Abstract: A practical kerning method and electronic typo-graphic/editing apparatus which is capable of arranging characters such that two characters do not come too close to each other across a small character or sign included in a character string. In positioning an object character with a space reduction relative to an immediately preceding character, a space (character space) between the first character and the third character of three characters, for example, is determined after the three characters are arranged with successive space reductions. This first to third character facing space is checked to see if it is smaller than a reference space. When the first to third character facing space is smaller than the reference space, a correction is made to at least one of a space reduction amount for the second character and a space reduction amount for the third character.

Abstract: An information processing apparatus is constructed by a judging unit for judging a set mode and a control unit for performing a bold process to an object in a document and outputting the document to another apparatus such as a printer in the case where the judged mode is a facsimile mode and for not performing the bold process to the object in the document and outputting the document to another apparatus in the case where the judged mode is a normal print mode. The control unit obtains information indicating whether the printer has a rendering function or not through a two-way interface. When the printer has the rendering function, the document is outputted to the printer in a format of a page describing language. When the printer doesn't have the rendering function, the document is outputted to the printer in a form of image data. The bold process changes characters in the document to a bold type or changes a line width of lines in the document to a thick line width.

Abstract: A system for transmitting map data between a parent station and a child station. The child station extracts figure data from an optical disk, specifies the retrieval range and transmits it as data for extraction to the parent station. Upon receipt, the parent station extracts the figure data including the retrieval range from the database. Then the date and/or time of update of the figure data and also of the data for extraction are checked. When the date and/or time of the update of the data for extraction is earlier, the figure data is transmitted to the child station.

Abstract: A drawing method of computer graphics in which an approximation of a model is executed in consideration of a target point of the observer, a position of model, a size of model on a picture plane, and a moving speed of model are considered and, further, a feeling of physical disorder that is given to the eyes of a human being is reduced is provided. Geometric model data inputted in step S1 is subjected to a filtering process in order to reduce a complexity of the model in step S2 and an outline of the model is extracted in step S3. As for the model from which the outline was extracted, characteristic points to which the human being largely react are extracted from such an outline in step S4. The processes in steps S2 to S4 are executed by a number of times as many as the number of necessary hierarchies (step S5). The characteristic points extracted every hierarchy in step S4 are made correspond among the hierarchies in step S6.

Abstract: An apparatus for tracing contours of segmented regions in an image includes a zero masking unit to produce a closed contour loop for each of the segmented regions, a tracing circuit for sequentially assigning each of the non-zero masked pixels on the closed contour loop as a tracing pixel, comparing the tracing pixel with a set of its adjacent pixels located at a rightward, an upward, a leftward and a downward directions with respect to the tracing pixel to select one of the adjacent pixels having a luminance level identical to that of the tracing pixel and updating the tracing pixel with the selected adjacent pixel with until the updated tracing pixel coincides with the tracing pixel selected first.

Abstract: An electronic filing apparatus includes a reading unit which reads an image of a document, a storage unit which stores the read image, a display unit which displays the stored image, and a printing unit which prints the displayed image on a recording sheet. The apparatus further includes a line setting unit which sets a partition line within the displayed image in accordance with input data when the displayed image is greater in size than the recording sheet, a generating unit which generates split images by splitting the displayed image in accordance with the partition line to make each of the split images smaller in size than the recording sheet, and a print control unit which controls the printing unit to print each of the generated split images on the recording sheet.

Abstract: A coordinate address is generated which specifies the position in a square original tile area where pattern data is to be written for each pixel, and a check is made to determine if the coordinate address is adjacent any one of sides of the original tile area. When the written pixel is adjacent any one of sides of the original tile area, the position of a pixel is calculated which is adjacent the written pixel on another tile area adjacent the original tile area along that side, and the position of the adjacent pixel when the adjacent tile area is laid on the original tile area is calculated as a shifted position of the adjacent pixel. The positions of the written pixel and the shifted position are rotated predetermined angle about the center of a polygon at least once to obtain rotational positions. Pixel values are additionally written at these shift and rotational positions.

Abstract: A system for virtual environments in which graphical objects are depicted in a space to achieve the required high accuracy regardless of location through establishing locales or subdivisions of the global coordinate system and establishing an origin for each locale, such that the specification of position and movement of a graphical object in the locale can be made with greater precision than using a global coordinate system, thus eliminating the need for high-precision floating point processors or emulation. The system permits designers of virtual environments to work independently on their locales, with overlap being controlled through specifying distance between locale origins as well as relative orientation between the locales. The system also permits ignoring information from non-relevant distant locales to, minimize processing and network bandwidth requirements.
