Abstract: A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: Apparatus for identifying video content includes a scene detector to detect a plurality of consecutive scenes in the video content. The video content may include a video program and an advertisement contained within the video program. A signature generator determines a scene change signature for each of the plurality of consecutive scenes. A content identifier provides the plurality of scene change signatures to a comparator that compares the plurality of scene change signatures to a database having a plurality of video content items to identify the video program. The database includes an ordered plurality of previously determined scene change signatures for each item of video content in the database. The content identifier receives an identification of the video content from the comparator. The content identifier may further receive information related to a position of the plurality of scene change signatures within the ordered plurality of previously determined scene change signatures.

Abstract: This is directed to efficiently identifying alternative display attributes for displaying text in a display region when default display attributes are inadequate for displaying the text. Many electronic device user interfaces are designed based on text in a default language. When interfaces are translated for use in other languages, the translated interfaces can include words or phrases that are longer than the corresponding text in the initial language. To quickly find an adequate, alternate display attribute for the longer text (e.g., a new font size), the electronic device can calculate assumed reduced text box sizes for displaying the text should display attributes of the text be reduced. The electronic device can select an adequate reduced text box, and reduce the display attributes by an amount corresponding to the reduced text box.

Abstract: Processes, machines, and computer-readable media are provided for expanding and simplifying a polygon or reducing and simplifying a polygon. Polygon expanding or reducing logic receives information that represents a polygon having a set of vertices. The polygon expanding or reducing logic determines another polygon having another set of vertices, such that the other polygon encompasses or is encompassed by the polygon, by determining, for each vertex of the set of vertices, a new set of vertices that are derived from the vertex and are at least a particular distance outside or inside the polygon. The vertex reducing logic determines whether an intermediate vertex is within the particular distance of a proposed segment between two other vertices of the other set of vertices, even though the intermediate vertex is not on the proposed segment, and, if so, removing the intermediate vertex from the other set of vertices.

Abstract: Before reducing a font size of a Chinese character, a to-be-adjusted standard radical is determined according to a non-neighboring outline ratio of a standard radical, and a radical serial list is established for the to-be-adjusted standard radical in a font database, for the purpose of consecutively updating the to-be-adjusted standard radical in the future. While the Chinese character is reduced by its font size, a radical serial list corresponding to the to-be-adjusted standard radical is first searched. The to-be-adjusted standard radical is then updated into a transformed radical step-by-step according to the radical serial list. At last, the transformed radical is used for replacing the to-be-adjusted standard radical to generate a transformed character, so as to achieve the effect of fine-tuning the Chinese character having the reduced font size.

The handwritten character is recognized as the reference character if more than a predetermined number of the segments in the image have the pixel ratios within the respective value ranges of the reference character.

Abstract: Methods, systems, and programming for producing and displaying a scaled-down representation of subpixel-optimized images and digital content including such images that is represented by a mark-up language. Some embodiments display the text in such digital content using a different subpixel optimization than that used for the images.

The method includes an iterative process which selectively removes various pixels, defining an outline of a font character while maintaining a removal criteria, which results in a nonlinear height reduction in order to produce a font of a desired height.

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.

Characters are defined in a font collection using segmented outline forms and common references stored to curve segments for similar segments in different characters of the font collection. Compressing the font collection preferably includes applying an entropy encoding data reduction. The common references are stored in a segment storage location. Another aspect includes decompressing a font store containing a compressed collection of outline fonts. The uncompressed curve segments are scaled so as to match a requested size for a letterform.

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.

Also, embodiments of the present invention are operable for resizing simple polygons that may include holes.

Abstract: Image data processing and image rendering methods and systems whereby images are displayed on display devices having pixels with separately controllable pixel sub-components. Images, such as text characters, are displayed on a display device with at least some features being rendered with sub-pixel precision. The displayed advance width of a character displayed with sub-pixel precision is compatible with the advance width of the character if it had instead been displayed with a conventional full pixel precision rendering process. Thus, characters are displayed with sub-pixel precision, resulting in improved resolution and readability, while the advance width and the corresponding size and spacing of the characters and the overall formatting of the document remains the same compared to documents and characters rendered using conventional full pixel precision processes.
