基于OV7620的视频信息采集系统的设计与实现

Design and implementation of video information collection system based on OV7620

视频信息采集系统是全数字实时无线多媒体传输系统中的前端处理部分,从数字图像传感器来的原始图像质量在整个系统的性能评价中占有非常重要的地位,由此介绍了一种用于多媒体传输前端的视频采集系统,阐述了该系统的总体结构和工作原理,并对其中的关键硬件芯片OV7620进行了介绍和设计,以及分析了系统的主要的软件设计.最后对做作的样机系统进行了调试,在Windows XP操作系统下采集图像质量良好,具有很好的实用价值.

The video information collection system is the front part of the digital real-time wireless Multi-media system. The quality of the raw picture from the digital picture sensor takes an important position in the evaluation of the total system. In this paper, a new style video information collection system is introduced. The structure and principle of this system is proposed. The important chip OV7620 in this system is described and designed. The software system is designed and implemented. The picture collected under this system shows a good quality and has well practical value.
