应用于图像融合的新型视频信号显示系统

A New Video Signal Display System for Multi-spectrum Image Fusion

介绍了采用专用视频 D/ A转换芯片和可编程逻辑器件 (CPL D)构成的视频信号显示系统。系统以CPL D作为控制单元和外围接口 ,采用 FIFO作为缓冲接口 ,能有效实现视频信号实时显示与读取的并行进行 ,具有整体电路简单、可靠性高、功能集成度高、编程方便的优点。作为输出模块 ,在多频谱图像融合系统中 ,该视频显示系统将融合后的多频谱或多波段图像以 RGB三基色方式提供给显示器等显示设备 。

A new video signal display system that has been developed by using special D/A converter,large scale CPLD device is dascribed in this paper.Through using CPLD devics as contrd unit and peripherals interface and FIFO as buffer interface the system can realize video signal real time display and read in parallel.The system has a lot of characters,including high integration and reliability,small volume,simple interface and in system programmability,etc.As the output module,the system has been applied to a multi channel image fasion system to provide fused multispectral images or multiresolution images for monitor in RGB mode.The effect is satisfying.
