| Abstract(in English) | The gamut of RGB color space is a cubic and its side range is [0,255]. Therefore, it is very easy to judge whether the color is in a gamut or not in RGB color space. However, in other color spaces, for example, in CIELAB color space, sometimes it is difficult to do such a judge because the shape of its gamuts are very complex. In this report, the method to judge whether the color is in a gamut or not for CIELAB color space is shown. Then, by using the judging method and a bisection method, the algorithm to grasp the brightest color in the input hue, that is, the boundary of the gamut, is also proposed. Moreover, an application of the grasping a gamut is illustrated to prove the effectiveness of the proposed algorithm. |
