【摘要】 设计并实现了一种数字图像采集系统,系统采用CMOS芯片MCM20027采集图像,在CPLD的时序控制下,通过USB2.0设备接口芯片CY7C68013来传输图像,然后在上位机进行处理。论文给出了此系统的软、硬件模块具体设计方法。实践表明,此款图像采集系统即插即用、分辨率高、图像刷新频率高、图像质量好。更多还原

【Abstract】 A high-resolution digital image collection system is designed and developed.In this system,a camera-on-chip MCM20027 is used for collecting image data,and an equipment-interface-chip CY7C68013 of universal serial bus 2.0 is designed to transfer image data,and a complex programmable logic device is used to control the time sequences between them.The detailed techniques of hardware and software modules are given in the paper.The experimental results show that the image collection system have good performance in image quality,image renovating frequency and high resolution.更多还原
