| 摘 要： | 针对投影仪与显示器显示颜色不一致的问题,提出了一种利用查找表的方式实现显示器到投影仪颜色再现的方案,并基于FPGA技术开发了相应的硬件系统。利用人眼视觉特性对显示器和投影仪上分别显示的几个不同色块颜色进行匹配,根据颜色再现原理计算出每帧图像所有可能像素点的对应转换值,将该值通过USB接口传输给颜色再现装置并存入到FPGA内部的3张查找表中。使用时,将PC机输出的视频信号作为地址读取查找表信息输出给投影仪显示,从而实现了从显示器到投影仪的颜色再现。经实测,验证了该方案的有效性。

| Abstract: | For the color inconsistencies between the projector and the monitor,this paper,advanced a method of Look-up table,proposed a color reproduction conversion from the display to the projector design,and exploited the hardware system which based on the FPGA technology.Making use of the characters of human visual,we matched several different colors displayed between projector and display,each frame is calculated the corresponding conversion of all the possible of the pixel based on the color reproduction theory,... |
