Image Processing Method and Display Apparatus Using the Same

A display apparatus comprising:

• an RGB-to-HSV converter configured to receive image data in an RGB color space and converts the image data in the RGB color space to an HSV color space;
• a compensator configured to compensate for the HSV data on a basis of a hue data of the image data in the HSV color space;
• an HSV-to-RGB converter configured to receive the compensated image data in the HSV color space and convert the compensated image data in the HSV color space to a compensated image data in the RGB color space;
• and
• a display unit configured to receive the compensated image data in the RGB color space and display an image on a basis of the compensated image data in the RGB color space.

A method for processing image data, comprising:

• receiving image data represented in an RGB color space, the received image data having a first color gamut;
• converting the received image data represented in the RGB color space into an HSV color space, the converted image data represented in the HSV color space having a second color gamut that is less robust than the first color gamut;
• compensating for changes of skin tone within the converted image data represented in the HSV color space based on a hue data of the converted image data represented in the HSV color space;
• and
• converting the compensated image data represented in the HSV color space back into the RGB color space.
