为了解决高帧频大面阵CCD相机图像数据量较大、存储实时性较低、高清图像显示中灰度级损失等问题,设计了一种大容量存储与高清显示系统。首先,结合高帧频大面阵CCD相机的特点,详细介绍了大容量存储与高清显示系统的组成;其次,为了满足面阵CCD相机高数据率的存储需求,对SATA硬盘Ultra DMA模式的读写方式进行了针对性的设计;然后,详细阐述了12bit高清显示器DVI接口的设计;最后,对系统的存储速率进行了测试,并且对普通显示器和高清显示器显示的图像进行了比较。实验结果表明:系统在Ultra DMA模式下实际传输速率最高可以达到85Mb/s,12bit高清显示器显示图像的对比度更强、层次更分明,提高了面阵CCD相机图像数据存储的实时性,同时保证了高灰度级图像的无损失显示。 In order to solve the problems of large frame rate large area CCD camera with large image data amount, low real-time storage and gray-scale loss in high-definition image display, a large-capacity storage and high-definition display system is designed. Firstly, the composition of high-capacity storage and high-definition display system is introduced in detail according to the characteristics of high frame rate large area CCD camera. Secondly, in order to meet the high data rate storage requirements of area CCD camera, Then, it elaborates the design of DVI interface of 12bit high-definition display. Finally, it tests the storage rate of the system and compares the images displayed by ordinary display and high-definition display. The experimental results show that the system can achieve the maximum transfer rate of 85Mb / s in Ultra DMA mode, and the contrast of 12-bit HDTV display image is stronger and the layer is more distinct. This improves the real-time storage of image data in area CCD camera, Lossless display of high-grayscale images.
