摘要： A color data conversion apparatus and method. The color data conversion apparatus includes a K ratio calculator for outputting a K ratio that is calculated using entered color data; a K ratio adjuster for adjusting the calculated K ratio, which is output from the K ratio calculator, in reference to gamut boundary descriptors (GBDs) corresponding to a K ratio and outputting the adjusted K ratio as a final K ratio; and a CMY ratio calculator for calculating C, M, and Y ratios based on the final K ratio. When converting the entered color data to the CMYK data, the calculated K ratio can be adjusted to the K ratio printable by use of the K GBDs. Accordingly, the printing apparatus can substantially print according to the calculated K ratio and thus the degradation of the printing quality can be avoided.

摘要： Disclosed is a method of creating a color-mapping lookup table and a color-mapping method using the same. The method of creating a color-mapping lookup table includes; obtaining color-space data for respective solid colors specified as lattice points of the color-mapping lookup table, obtaining color-space data for respective achromatic colors specified as lattice points of the color-mapping lookup table, and tabulating the color-space data for the respective solid colors specified as the lattice points and the color-space for the respective achromatic colors specified as the lattice points. Therefore, the methods can create a color-mapping LUT in which significant colors such as solid colors or achromatic colors are specified as lattice points, so that significant colors are more optimally reproduced since device data for the significant colors are not calculated through interpolation.

摘要翻译：公开了一种创建颜色映射查找表的方法和使用其的颜色映射方法。创建颜色映射查找表的方法包括：获取作为色彩映射查找表的格点指定的各个实心颜色的颜色空间数据，获得作为颜色映射查找表的格点指定的各种无彩色的颜色空间数据，并列出颜色空间数据指定为晶格点的各个固体颜色以及指定为晶格点的各个无彩色的颜色空间。因此，该方法可以创建颜色映射LUT，其中将诸如纯色或无色颜色的有色颜色指定为网格点，使得由于不通过插值计算显着颜色的设备数据，所以显着颜色被更优化地再现。

摘要： A technique for controlling synchronous and asynchronous devices connected to an inter-integrated circuit bus (I2C bus) is designed such that, in a system using an inter-integrated circuit bus (I2C bus), the controlling system includes a central processing unit (CPU), a system memory and a shared memory, each of which is connected to the system bus. The shared memory saves information about a variety of devices, which are connected to the I2C bus. The controlling system further includes a microcontroller for communicating with the shared memory and for controlling the devices which are connected to the I2C bus, asynchronous master devices which are controlled by the microcontroller, and synchronous slave devices which are controlled by the microcontroller. The microcontroller, the non-synchronous master devices and the synchronous slave devices are connected to the I2C bus.
