首先感谢您选用大恒图像产品，DH-CG300视频采集卡是我公
司新近开发的彩色/黑白视频图像采集卡。它具有使用灵活、集成
度高、功耗低等特点。由于采用PCI总线，所采集的图像数据传
输基本不占用CPU时间，并可将图像直接传送到计算机内存或显
存，是当今市场上相当流行的一种图像采集卡。它适用于图像处
理、工业控制、多媒体监控、办公自动化等领域。
本手册详细介绍了DH-CG300的工作原理，软硬件安装、使用。
DH-QP300是在一块单板上集成了四块DH-CG300，但每一块
DH-CG300仅支持两路复合视频输入。DH-QP300特别适于多画面同
时采集。
DH-CG320是基于PC/104-Plus结构的图像采集卡，该卡可进
行高质量彩色/黑白视频信号实时采集。并通过PCI总线传送到主
板内置的VGA卡上实时显示或传送到计算机内存中实时存储。视
频数据的传送过程由图像卡控制，无需CPU参与。目录
