摘要 详细介绍了一种行问转移型面阵CCD的图像采集系统的原理及硬件组成。设计了基于复杂可编程逻辑器件(CPLD)的CCD驱动时序发生器及上电顺序可控的智能电源,采用视频处理专用集成芯片对视频信号进行去噪量化。测试结果表明该系统实现了对面阵CCD信号快速而准确地采集,其硬件电路结构简单、调试灵活、通用可靠,具有一定的实用价值和应用前景。 This article introduces detailed the principle and hardware composing of an image acquisition system according to the interline-transfer area array CCD. The driving schedule generator based on complex programmable logic device(CPLD) for CCD and intelligent power supply Whose sequence of power-on is controlled have been designed. The CCD output video signal was processed by adopting specific integrated circuit for CCD video signal processing in order to get rid of noise and quantize. The testing result indicates that the system made fast and precise sampling of is characterized by simple framework, flexible debugging, universal and high CCD signal .The circuit reliability and has a certain practical value and application foreground.
