COLOR SIGNAL PROCESSING METHOD AND APPARATUS, AND STORAGE MEDIUM FOR PERFORMING THE METHOD

摘要

Methods, apparatuses and storage mediums for processing color signals of an image are provided. A method includes converting an input signal in a first color space into a luminance component and a saturation component in a second color space, determining a boundary of the second color space by using the luminance component and the saturation component, determining whether the converted input signal is outside the boundary, and matching the saturation component so that the converted input signal outside the boundary of the second color space enters the second color space. The method may be carried out by a non-transitory computer readable storage medium. An apparatus includes a color signal a color space converter configured to convert an input signal in a first color space into a luminance component and a saturation component in a second color space; a color space boundary determiner configured to determine a boundary of the second color space by using the luminance component and the saturation component, and determine whether the converted input signal is outside the boundary; and a saturation matcher configured to match the saturation component so that the converted input signal outside the boundary of the second color space enters into the boundary of the second color space.
