摘要
介绍了一款网络摄像机的硬件结构和软件编程。硬件结构主要由索尼的CCD ICX205AK,Analog Devices模拟前端电路AD9923A以及Xilinx的FPGA XC3S1200E、TOKYO的JPEG压缩芯片TE3310RPF和ATMEL的ARM芯片AT91RM9200等组成。软件设计给出了AT91RM9200的驱动程序、应用程序编写方法。实验结果表明,该设计方案每秒可以采集、压缩、传输140万像素图像7.5帧,图像质量较好。
A design method of network video camera is introduced. ICX205AK is used as CCD sensor; AD9923A is used as the analog front end; other chips inelude XC3S1200E and TE3310RPF. How to program the software of AT91RM9200 is proposed. The testing results show that the design can collect, compress, transmit 7,5 frame 1.4Mega pixels image per second.
