Abstract: This article is based on CMOS image sensor which is commonly used in image acquisition. It applies 32-bit ARM9 microprocessor S3C2410A as the CPU to control other function modules and designs embedded Arm9 image acquisition system for the realization of machine vision. The main function modules are SDRAM memory cell, image acquisition unit and Ethernet transmission module, UART serial port communication module, Flash module, power supply module, etc. Compared with machine vision systems of the traditional "image acquisition card - PC - terminal control device" model, the image acquisition system has advantages of small volume, low cost, low power consumption, strong real-time performance, etc. And it can be used for practical application in video image monitoring, automatic detection, medical and military detection and so on. In a word, it has a good application prospect.

 

Keywords: CMOS Image Sensors, Embedded, ARM9, Image Acquisition.
