Method and apparatus for improving quality of images using complementary hues

An apparatus for improving the quality of images using complementary color contrast, the apparatus comprising:

• an image input module which extracts color information of each of a plurality of pixels of an input image;
• a color gamut determination module which determines whether the input image comprises both a first pixel belonging to a first group and a second pixel belonging to a second group with reference to the extracted color information;
• and
• a hue conversion module which converts a first hue of the first pixel into an optimum point of the first group, and converts a second hue of the second pixel into an optimum point of the second group,
• wherein the first hue corresponding to the optimum point of the first group and the second hue corresponding to the optimum point of the second group are complementary to each other.
