摘要:
在基于XScale架构的处理器PXA27x及Windows CE操作系统平台上,分析了Quick Capture接口的结构及显示原理,并给出了摄像头的硬件电路设计.采用Windows CE流接口驱动模型,讨论了驱动程序的框架和摄像头的工作状态划分,并详细介绍了DMA中断采集图像的实现原理.采集的图像帧连续显示在LCD控制器的OverLay窗口上,完成实时预览.经过验证,系统可以正常采集、传输和显示图像.
Abstract:
On the platfo rm consisted of PXA27x processo r based on the XSca le a rchitec ture andW indow s CE operating system, th is paper ana lyzes the struc ture and display pr inciple o f the Qu ick Capture interface, and presents the hardware circu it design of the cam era. The paper usesW indow s CE stream interface dr ive rm odel to discuss the fram ew ork of driv  e r and the wo rking sta te d iv ision of cam era, and presents the rea liza tion pr inciple of im age co llection us ing DMA inter  rupt in deta i.l Co llec ted image frames a re displayed in the Ov erLayw indow o f the LCD contro ller continuously, and then rea l tim e prev iew is com pleted. The system can properly co llect, transm it and d isplay im ages through verification.
