改变传统的基于PCI插槽的图象卡加摄像头的图象采集模式,介绍了利用CY7C68013和OV9620芯片开发数字摄像系统的设计方案。重点阐述了WDM模式的USB设备驱动程序与采集视频流的界面应用程序的设计。系统可以12帧/s的速度动态显示采集的图象。
Change the traditional PCI slot-based image card plus camera image acquisition mode, the use of CY7C68013 and OV9620 chips introduced the development of digital camera system design. Focus on the WDM mode USB device driver and capture video stream interface application design. The system can dynamically display the captured image at 12 frames per second.
