摘要 |
A method of and apparatus for converting a color space. The method includes: separating a color signal of a given pixel into a brightness component and a saturation component; obtaining a boundary value of the saturation component of a color gamut, to which the color signal belongs, in a first color space using the separated brightness component and saturation components; and converting the first color space into a second color space in which saturation components and hue components are independently controlled using the obtained boundary value.
