A color conversion method includes determining a race by recognizing a skin region in an input image, selecting a preferred skin color to apply to the skin region based on a plurality of preferred skin color information preset per race, and correcting a color of the skin region using the selected preferred skin color. Additionally, a color conversation apparatus includes a control unit to determine a race by recognizing a skin region in an input image input, and to select a preferred skin color to apply to the skin region, based on the plurality of the preferred skin color information stored in a storage unit, and a compensation unit to correct a color of the skin region using the preferred skin color selected by the control unit. Hence, the skin color per race can be adequately converted to the color which can satisfy the user.

Color conversion apparatus and method thereof

A color correction method includes displaying an expected print image of a test image of the image forming apparatus on a monitor, outputting the test image to the image forming apparatus, performing color matching between the output test image and an expected print image on the monitor, changing an ICC profile of the monitor according to the performed color matching, and generating a print data using the changed ICC profile. Also a print controlling terminal which performs the color correction method.

Print controlling terminal and color correction method generating print data using monitor profile changed based on comparison of printed test image to expected print image displayed on monitor

A method of generating illumination characteristic data around an image display device, includes making predetermined illumination characteristic data around the image display device into a data format comprising a type block and an illuminance block. The type block indicates information on a type of illumination, and the illuminance block indicates information on the illuminance of illumination.

Method and apparatus for generating characteristic data of illumination around image display device

An apparatus and method for converting color data are provided. The method includes generating a CMYK color gamut extended from a CMY color gamut that consists of a cyan (C) colorant, a magenta (M) colorant, and a yellow (Y) colorant, by use of the CMY color gamut and a black (K) colorant; mapping input colors using the generated CMYK color gamut; converting color data of the mapped input colors to CMY data; and converting the CMY data to CMYK data. Accordingly, natural representation and printing of low-lightness colors and high-saturation colors can be attained.

Apparatus and method for converting color data using color gamut extension

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.

Color data conversion apparatus and method using gamut boundary descriptors

A method of generating illumination characteristic data around an image display device, includes: obtaining predetermined illumination characteristic data around the image display device; and making the predetermined illumination characteristic data into a data format comprising a type block and an illuminance block. The type block indicates information on a type of illumination, and the illuminance block indicates information on the illuminance of illumination.
