| 摘 要： | 在分析DALSA公司的IA_G3 COMS面阵传感器驱动时序基础上,设计了SPI模式的寄存器配置电路,实现了CMOS图像传感器的成像功能.通过开窗口技术,方便地实现了感兴趣区域图像的读出.选用现场可编程门阵列(FPGA)作为载体,使用VHDL语言对驱动时序发生器进行了硬件描述.采用Quartus II 7.1软件对所做的设计进行功能仿真后,将程序烧写入FPGA(ALTERA公司的EP2C20F484C8)内,对IA_G3图像传感器进行配置,实验结果表明,上述电路满足CMOS相机的驱动要求.

| Abstract: | Driving schedules of IA_G3(Area Array CMOS sensor)have been examined.Through the SPI(The Serial to Parallel Interface),the driving schedule generator has been designed for configuring sensor.The target of imaging is achieved.Through the technique of windowing,the region-of-interest is read out facility.FPGA(Field-Programmable Gate Array) has been chosen as the hardware design platform.Driving schedule generator has been described with VHDL.The function simulation of the system is successfully fulfilled with... |
