摘要
激光显示中必须将传统光源三基色向激光三基色进行色域映射,针对传统的一维查找表和三维查找表存在的缺点,介绍了一种三维简化查找表,在不影响显示图像质量的情况下,大大减少查找表的存储容量,并具有较快的查表速度,适合在FPGA,ASIC等硬件中实时实现。
Laser tricolor needs mapping the color gamut of traditional lamp-house to the color gamut of laser. Traditional one-dimensional look-up table （LUT） can＇t correct display characteristic exactly. Three-dimensional look-up table can correct display characteristic accurately, but it has to need large memory space and it＇s difficult to implement in real-time hardware. In this paper, a new three-dimensional reduced look-up table is proposed, which can reduce LUT＇s memory space and has a high accessing speed without influencing the display quality. This method can be easily implemented in real-time hardware, such as FPGA and ASIC.
