  • Publication number: 20140232741
    Abstract: An image processing method includes receiving an RGB data, converting the RGB data to an HSV data configured to include hue, saturation, and value compensating for the HSV data on a basis of a hue data of the HSV data, and converting the compensated HSV data to a compensated RGB data. The compensating of the HSV data includes reading out a compensation data corresponding to the hue data from a look-up table and compensating for the HSV data using the compensation data. The data are compensated on the basis of the hue in the HSV color space and the saturation and value are preserved, and thus the image, e.g., the memory color like the skin color, may be prevented from being distorted.
