    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: 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.
