摘要： A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

摘要： An index determination element selects index values as a function of the source color values. The index values pointing to LUT color values stored in a lookup table unit. The LUT color values read from the lookup table unit are used to generate output color values. Each output color value corresponds to a pixel, a first component of the output color values is output for at least two pixels at a time and second components are output separately for each of these at least two pixels. As a result there is a space of combinations of index values that results in substantially the same first component of the output values, even though they points to substantially different LUT color values for these at least two pixels. The index determination element selects a combination from this space to minimize an error in the second components of the output color values for the at least two pixels.
摘要翻译：索引确定元素选择索引值作为源颜色值的函数。索引值指向存储在查找表单元中的LUT颜色值。使用从查找表单元读取的LUT颜色值来生成输出颜色值。每个输出颜色值对应于像素，输出颜色值的第一分量一次输出至少两个像素，而对于这些至少两个像素中的每一个分别输出第二分量。因此，尽管它们指向这些至少两个像素的基本不同的LUT颜色值，但仍然存在导致输出值基本上相同的第一分量的索引值的组合的空间。索引确定元件从该空间中选择一个组合，以最小化至少两个像素的输出颜色值的第二分量中的误差。

摘要： The present invention discloses a method and system for controlling a system display from the processor controlling a fiscal printer. The system display is controlled by generating an overlay image in a storage device along with overlay image selector data. The overlay image selector data is used to control modifying circuits that can substitute or otherwise modify, with overlay image data, all or a portion of the system display image generated by application software. Since the fiscal printer hardware and firmware is not a part of the particular application software running on a point of sale device the control function of the fiscal printer need not require modification of application software or hardware.

摘要： A method and apparatus for processing data of different sizes begins by processing first data to produce an n-bit resultant. Such processing may be performing an arithmetic function upon the data. In addition, second data is processed to produce an m-bit resultant. Such processing of the second data may also include performing an arithmetic function upon the second data. The processing then continues by mixing the n-bit resultant with the m-bit resultant to produce an m-bit mixed resultant. For example, the first data may be representative of RGB graphics data that is processed by a graphics core to produce an 8-bit resultant. The second data may be representative of video data that is processed by a video core to produce a 10-bit resultant. A mixer mixes the 8-bit graphics output with the 10-bit digital video output to produce a 10-bit mixed output. A digital-to-analog converter converts the 10-bit mixed output into an analog signal.

摘要： A period-based method for converting digital image data for a plurality of pixels from a first bit depth to a second bit depth includes receiving an input scanline of an arbitrary length comprising digital image data for a plurality of input image pixels. Each of the input image pixels is defined at the first bit depth. The input scanline is divided into a plurality of periods each comprising digital image data for a select number of input image pixels. The period is selected so that the image data for the select number of input image pixels exactly comprises m bytes when defined at the first bit depth and exactly comprises n bytes when defined at the second bit depth, wherein m and n are different integers. For each of the periods in succession, the image data for each of the select number of input image pixels is converted from the first bit depth to the second bit depth. A code generator generates hard-coded conversion operating instructions and a look-up table for specified bit conversion operations and generic conversion operating instructions for all other bit conversion operations.

摘要： An apparatus for processing digital display data is described, wherein the digital display data has a fixed number of pixels in each display line, and the apparatus has a horizontal averaging means and a vertical averaging means. The horizontal averaging means identifies pixel data corresponding to a first pixel, a second pixel, and a third pixel, where the first, second, and third pixels are consecutive pixels in the same line of display data, and then smoothes the intensity values of the first, second, and third pixels, after which the smoothed values are stored. The vertical averaging means for identifies pixel data corresponding to a fourth and fifth pixels, where the fourth and fifth pixels are vertically adjacent to each other, and then smoothes the intensity values of said fourth and fifth pixel data, and storing the resulting smoothed values.

摘要： An apparatus for converting an input image in an input color space to an output image in an output color space. The apparatus has a cache memory for storing from external memory, sparsely located output color values corresponding to input pixels closest to the current input pixel of an image stream, if not already present in the cache memory. The apparatus also has retrieval means for retrieving, from said cache memory, the sparsely located output color values corresponding to the current input pixel of the stream. The retrieved output color values are interpolated by interpolation means to derive an output color value in said output color space.
