Abstract
In this paper, we propose the color-temperature conversion system with compensated X-chromaticity coordinate. It uses a linear regression to improve the error of color-temperatue calculation in conventional systems. It also extend the color-temperature range from 1,667K to 25,000K to Provide a wider color-temperature range. We show the effectiveness of the proposed method by comparing the performance of the proposed method with those of the Robertson's and the existing methods. The proposed method is experimetally verified by displaying the results on a TV system through the Xilinx FPGA XCV2000E-BG560.
