Abstract: The system, method and program of the invention enables a presentation authoring tool, that is used to create presentation data for later projection, to determine a recommended font size for the created presentation data displayed on a display screen of a computer executing the presentation authoring tool. The user interface presents a display screen for receiving input of an expected viewing distance for the later projection of the presentation. The recommended font is determined based upon the expected viewing distance of the later projection having a projected font size viewable by a person, having a certain vision capability, at the expected viewing distance. The expected viewing distance may be a maximum viewing distance or a room depth of a room in which the later projection takes place.

Abstract: Techniques for performing combined scaling, filtering, and/or scan conversion are disclosed that reduce that amount of line buffer space required in the overall design of a video processing system. In particular, coefficients from all or a sub-set of the scaling, filtering (smoothing/sharpening), and scan conversion filters are combined into one representative coefficient that can be applied in a single generic algorithm. Thus, implementation costs are reduced, particularly in system-on-chip implementations.

Abstract: Methods and apparatus implementing and using techniques for rendering a stroke (e.g., a line or glyph). An initial adjustment value can be calculated for the stroke, and an offset amount calculated based on the initial adjustment value, such that a minimum number of device pixels will be marked by the stroke after adjusting density values of device pixels representing the stroke.

A length of an edge of the stroke that passes through a device pixel can be calculated, and the density value of the device pixel adjusted by a final adjustment value based on the initial adjustment value and the length of the edge of the stroke.

Abstract: A technique is disclosed for dynamically adjusting dimensions of characters, such as digits, displayed on a configurable display, such as in a human-machine interface. The height of the characters is fixed and the width is altered depending upon the number of characters to be displayed, resulting in changing aspect ratios for the characters. The width may be set to a predetermined maximum character width if all characters to be displayed will fit within the available space, or the width may be reduced to accommodate more characters. The technique may take into account cushion spaces for borders or frames, as well as spaces between characters. The resulting display allows for a change in the number of significant digits in a displayed numeral, while maintaining excellent readability.

Abstract: A computer-implemented simulated emboldening mechanism for emboldening an input overscaled bitmap to generate an emboldened overscaled bitmap. The simulated emboldening adjusts the number of subpixels to turn on in the direction of emboldening taking into account contextual information regarding surrounding subpixels. Since the emboldening works directly from an overscaled bitmap, and takes such contextual information into account, legibility and readability of the resulting emboldened character is enhanced.

Abstract: The principles of the present invention relate to adaptively filtering outlines of typographic characters to simply representative control data. A filtering module receives a set of control points (and instructions for connecting the control points) representing a graphical object, such as, for example, a typographical character. The filtering module adaptively filters out some variations in the outline of the graphical object to reveal common edges of the outline. The filtering module generates simplified control data that represents an outline of the common edges (e.g., representing a block “T”). Accordingly, based on the simplified control data, a computing system may be able to more efficiently recognize the graphical object represented by the control points.

To this end, frame images which are sensed by an image sensing unit and are sequential in the time axis direction are input from an input unit. The input frame images are smoothed by a filter unit. A background image generation unit generates an average image of a predetermined number of smoothed frame images as a background image.

An object extraction unit extracts an object region where a predetermined object is sensed, on the basis of the differential image.

Abstract: An object is to provide an image generation system and program which can realize a realistic, variable and natural representation of motion with less data. When the forearm (14) of an enemy character is hit, the forearm (14) is moved through a physical simulation by a vector of hitting force FH0. At the same time, vectors of hitting force FH1 to FH4 are sequentially transmitted to the brachium (16), chest (18) and hip (20) which are parent parts for the forearm (14) while their magnitude being sequentially attenuated. These vectors of hitting force FH1 to FH4 move these parent parts to generate a motion of the object. A rotational resistance force depending on its angular velocity and a restoring force for returning the part to its default posture act on each of the parts. When the object is hit, the play of motion based on motion data is switched to the generation of motion through the physical simulation.

Hints are transferred from characters of the first TrueType font to individual corresponding characters of the second TrueType font, and a hint is discarded where it appears inappropriate for a character of the second TrueType font. Further, the system maintains indicia of a discarded hint to indicate where a hint has been discarded.

Abstract: A compressed-domain-based algorithm reduces a source image to a given target size using a combination of downscaling, cropping, and region-of-interest identification. The source image is partitioned into a plurality of macroblocks, each macroblock containing a plurality of chrominance and luminance blocks, each chrominance block and each luminance block containing a DC coefficient and AC coefficients. To each macroblock, a first rule is applied based on values of the DC coefficient of the chrominance blocks in that macroblock to identify a particular type of texture in the image. Also to each macroblock, a second rule is applied based on select values of the AC coefficient of luminance blocks in that macroblock to identify edges in the image. The macroblocks within the image are then searched to find an area containing an area of interest based on the results of applying the first and second rules.

Abstract: The invention provides a font processing device. In font enlargement, a target font to be enlarged or reduced is divided into columns or rows, and a cost is calculated based on the pixel pattern formation for each column and row. In enlargement processing, a cost represents a line segment volume, and a column or a row that has low-cost, that is, has a pixel array close to a line segment, is difficult to be enlarged. Further, in reduction processing, a cost represents a degree of likeness to an adjacent column or row, and a column or a row that has a similar pixel pattern is reduced with priority. In practice, the column or row for the target font is decided based on the pixel formation of the target font for enlargement or reduction so that natural enlargement/reduction can be obtained. In addition, font modification is executed by using enlargement and reduction of the font.

Abstract: A method and system are provided for positioning characters within an arbitrarily sized graphics window in order to maximize the distribution of unused space. The method and system are particularly adapted for the redistribution of characters produced during a terminal emulation session with another computing system. Characters produced during the emulated session are adjusted to completely fill the graphics window, regardless of its size. A fill justification procedure distributes characters in areas within the graphics window that would otherwise appear as gutters or margins. A character spacing unit maintains correct character image proportions in the graphics window while not rigidly adhering to a uniform alignment of character rows and columns. A linear distribution procedure allows the character image to fill the graphics window completely with a natural appearance.
