大面阵CMOS实时同步成像及显示系统的设计

Design of a Large Array CMOS Image and Display System in Real-time Synchronization

为了能够实时成像和同步显示,设计了一种结构简单、携带方便的大面阵CMOS实时成像及显示系统,采用EPF10K50完成了MT9M413C36STM图像生成时序和SXGA显示时序及数据输出的多路转换设计.图像传感器的数据输出转换为两路,一路数据输出给处理电路进行图像实时处理;另一路经ADV7127视频数模变换后输出,可以连接SXGA形式的显示器同步显示图像.实验设计了相关硬件电路,并用VHDL语言编写了驱动程序,在Quartus 8.0的开发环境下,进行了调试.结果表明,该系统可以在1280×1024@60Hz逐行扫描模式下稳定地工作.

In order to achieve real-time imaging and simultaneous display,a lary array CMOS camera system with simple structure and portable size is designed.Making use of EPF10K50,image timing of MT9M413C36STM,display timing of SXGA and multiplex of output data are designed.Image sensor data is divided into two way signals.One way data outputs for processor electric circuit to deal with,the other way data through ADV7127 video AD transformation outputs to display simultaneity in SXGA.The related hardware electric circuit is designed,and the device driver is written using the VHDL language.Under the development environment of the Quartus 8.0,it is debugged.Experimental results show that this system can stably work in 1 280×1 024@60 Hz line-by-line scan.
