| Abstract: | In order to transform the color range from phosphor color to laser color, a real-time image processing system is designed. The platform is constructed by the high performance DSP chipset TMS320C6416T as the core digital processor and the field reprogrammable array FPGA. This paper presents three transformation matrixes of different wavelength lasers, and accomplishes the conversion between the phosphor tricolors to the laser tricolors on the image processing hardware platform. By using some acceleration algorithms, the transformation is speeded up. The experiments results show the method is effective to transform the color range of the laser TV. The saturation of the images is reduced. The method has its practical feasibility. |
