Abstract

Multiprimary displays are needed to reproduce the most of visible color. However, while using four or more primary colors, it is difficult to convert color uniquely, because multiprimary displays have variability of color conversion. Even though multiprimary colors can be converted, there are some false edges in the reproduced image by using the most of the current conversion methods. We introduce linear programming to the color conversion in order to get high accuracy and eliminate false edges. Although the linear programming can help multiprimary displays to reproduce images without false edges, it takes long time to convert high-definition images. Hence, a fast color conversion method that keeps the advantage of the linear programming is proposed. This method is constructed of decision tree and linear programming. Because the decision tree is a discrete classification method, color conversion by the decision tree must be implemented as a discrete classification problem. Therefore, we feed the results of the conversion by linear programming to the decision tree. As the result of the conversion by the method, fast color conversion was obtained in comparison with that obtained only by using linear programming. In addition, our method almost eliminated the false edges in the reproduced image.
