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.

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.

A method and system are disclosed for creating and using space-efficient color tables in an imaging system having an imaging object. The imaging object has processing conditions associated therewith, and a full size color conversion data lookup table. The color linearity of the imaging object is determined. The processing conditions of the imaging object are classified into data groups based on color linearity. A full size shared color conversion data lookup table common to the processing conditions for each of the data groups is calculated, and a small size delta color conversion data lookup table for each of the processing conditions is calculated from the differences between the full size color conversion data lookup table and the shared color conversion data lookup table. In use, the shared standard color conversion data lookup table and lo the delta color conversion data lookup table, which are stored in memory, are retrieved and used to calculate the full size standard color conversion data lookup table,

With respect to color characterization of color printers, the present disclosure relates to the identification of colorant combinations for color patches in a color characterization target, which contains different color patches, and which is measured calorimetrically or spectrally to color-characterize the printer. A black ramp is printed and measured. Substantially uniform steps on the ramp are selected by applying principal component analysis to the measured values or color values derived from the measured values, and by using a first principal component thereof to select the substantially uniform steps. For each of the substantially uniform steps identified, the above procedure is repeated on all chromatic ramps with black ink at a corresponding black level. Color values of the color patches are populated by using multiple combinations of the substantially uniform steps of the black channel and of the chromatic channels at the corresponding black levels that meet an ink limit.

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.

A performance apparatus 11 extends in its longitudinal direction to be held by a player with his or her hand. The performance apparatus 11 is provided with a geomagnetic sensor 22 and an acceleration sensor 23. At the time when the geomagnetic sensor and acceleration sensor determine that the performance apparatus 11 is kept within a sound generation space and has been moved by the player, CPU 21 gives an electronic musical instrument 19 an instruction to generate a musical tone of a tone color corresponding to the sound generation space. The sound generation spaces and corresponding tone colors are stored in a space/tone color table in RAM 26. Upon receipt of the instruction, the electronic musical instrument generates a musical tone of a tone color corresponding to the sound generation space.

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.

A performance apparatus 11 extends in its longitudinal direction to be held by a player with his or her hand. The performance apparatus is provided with a geomagnetic sensor 22 and an acceleration sensor 23 in its extending portion. CPU 21 gives an instruction to an electronic musical instrument 19 to generate a musical tone of a tone color at a timing when a position of the performance apparatus obtained by the geomagnetic sensor and acceleration sensor passes through a sound generation area defined in space, wherein the tone color of the musical tone corresponds to the sound generation area. The sound generation areas and corresponding tone colors are stored in an area/tone color table in RAM 26. Upon receipt of an instruction, the electronic musical instrument generates a musical tone having a tone color corresponding to the sound generation area.

An apparatus and method for providing calorimetric information are provided. A camera photographs an image including a desired calorimetric portion. A controller computes a mean color value of the desired colorimetric portion from the photographed image and retrieves a colorimetric value mapped to the computed mean color value from a pre-stored color table. If the colorimetric value mapped to the computed mean color value is retrieved from the pre-stored color table, a display receives the retrieved calorimetric value from the controller and outputs the colorimetric value as colorimetric information of the desired calorimetric portion.

A shoe light device with multiple color variations has at least a color-mixing LED, a power source, a vibration switch and a control IC. The color-mixing LED has several light-emitting chips of different colors, and is used to generate light of various colors. The power source provides electricity for the color-mixing LED. The vibration switch generates a trigger signal to the control IC when shocked. The control IC generates a drive signal to drive the color-mixing LED to flash a single-color light at least once after receiving the trigger signal. The color-mixing LED flashes a different single-color light each time according to a light color table determining the color variation order and frequency after receiving the drive signal. When a user wearing a shoe with the shoe light device installed therein walks, variations of different single-color lights can be displayed along with his steps.

A wavelet-based image compression system and method are presented. Compression is accomplished by performing a wavelet transformation of an input digital image. The resulting wavelet coefficients are compared to a threshold value. Coefficients falling below the threshold are discarded. The remaining coefficients are quantized. 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.
