Document output apparatus
A document output apparatus outputs a document made up of plural cells in such a manner that either the characters entered in cells or the backgrounds of the cells are colored in accordance with the kinds of data assigned to the cells. The document output apparatus has plural color tables, and each of these color tables stores plural color information corresponding to respective values of the data. When one of the color tables is designated, color information corresponding to the values of the cells are retrieved from the designated color table. The cells are drawn in the colors defined in the designated color table. Accordingly, it is possible to eliminate the need to define color information for each of the cells of the document.

Printing system for updating printing characteristics with a printing consumable
The flexible printing system is comprised of a printer that has printing characteristics that can be updated. A printer cartridge comprises printer data memory that either stores new printing characteristics or stores a location from the Internet from which these characteristics can be downloaded. The printer accesses the cartridge's printer data memory and checks the stored printing characteristics. If the printer can use these characteristics and they differ from the characteristics that are presently being used by the printer, the printer updates its printing characteristics using the printer data memory's printing characteristics. In one embodiment, the printer characteristics are color tables and dithering algorithms.

System and method for the compression and quantitative measurement of movement from synchronous video
InactiveUS7072521B1Character and pattern recognitionDigital video signal modificationImaging processingImage resolution
A system and method for optimizing and quantifying movement in synchronous video are provided. An image-processing computer obtains a synchronous video image, which is converted to color bitmap frames. Each frame is then sub-divided into smaller pixel blocks. Processed independently, the size of each pixel block is reduced by truncation of the color resolution and the use of a limited color table for the pixel block. The cumulative color difference in the pixel block is calculated and if it is below a threshold, the pixel block data will not be saved. Alternatively, the pixel block data is compressed and saved. Upon decoding, the color difference between each pixel and the same pixel in the preceding frame is compared. The color difference is assigned a pseudocolor and is displayed on the screen. Larger color differences are represented with more pronounced pseudocolors.

A method and system of determining the screen capability and rendering the appropriate display attribute is herein described. The present invention performs this task by using a color table, which contains a list of object types and a corresponding list of display attributes. The application program obtains the correct display attribute for the object by calling the color table, giving it an identifier of the object. The color table is indexed by the identifier of the object and a screen capability flag that is obtained, in one embodiment, from the operating system. The color table provides the display attribute for the specified object based on the screen capability flag. Advantageously, the application program does not need to know the computer's display capability. Furthermore, the application program needs only one piece of computer code, regardless of the number of display capabilities which are possible. Thus, memory space in the palmtop is conserved. In another embodiment of the present invention, the application program is allowed to modify the default values of the display attributes in the color table. Thus, an application program could use its own color to display an object if the default color is undesirable.

Method and system for the representation of color and other attributes in bitmap fonts
Colors are specified within the individual glyphs of a font by means of an indirect approach which employs multiple tables. The data values for individual pixels of a glyph identify entries in an index table, which pertains to a subset of all available colors. The entries in the index table map to a complete set of colors that are specified in a color table. As a result of this structure, the amount of data that is required to specify the individual pixels of a glyph can be minimized to the number of bits required to distinguish the colors within that glyph. The specification of all available colors within a single table permits that table to be shared among various resources, including bitmap fonts and outline fonts.

The quantized coefficients are then compressed using an entropy encoding technique, such as arithmetic, run length, or Huffman encoding, or a combination of Huffman and run length encoding. The wavelet transform can be an integer wavelet transform derived using a lifting scheme or correction method, while the quantization scheme can be sub-band oriented. Input color image pixels can be reduced using a color table. In addition, color pixels can be transformed between color spaces prior to wavelet transformation.
