Abstract
A method for airbrushing and a device therefor enable to perform an airbrush operation in which only lightness or chroma is varied. The airbrush device performs the airbrush operation to gradate a designated region or regions of RGB data by converting the RGB data in a RGB coordinate system into image data in a lightness, chroma and/or hue coordinate system, and designating airbrush information for performing the airbrush operation on the converted image data in the lightness, chroma and/or hue coordinate system. Image data corresponding to the airbrush information is extracted from the converted image data in the lightness, chroma and/or hue coordinate system, and the airbrush operation is performed on the extracted image data in the lightness, chroma and/or hue coordinate system based on the airbrush information.
