This paper presents a new region splitting method which uses perceptual color system. The algorithm is constructed from two major steps. First step is the region segmentation by the feature of the input image. The image is devided into three parts, one has the regions with high satulation, another is with low, and the other is with no satulation. Second step is the area extraction that is suitable for their features. At the first part of the image, the areas are extracted by using perceptual color system, especially hue information. Physical color system, like RGB is used for second part. In the last part, we use the lightness data.
