0引言对于需要以图象画面作为证据的防窃电远程视频监控系统,如何提高视频分辨率和压缩比,提高图像质量是技术关键。应采用数字化图象技术取代传统的闭路电视。本文介绍了一种基于USB总线的JPEG编码视频压缩模块,它具有图像分辨率高(130万像素)、压缩比大、接口简单等特点,可以 0 Introduction For the anti-trespassing remote video monitoring system that needs to take the image screen as evidence, how to improve the video resolution and compression ratio and improve the image quality is the key technology. Digital image technology should be used to replace traditional CCTV. This paper introduces a USB bus-based JPEG encoding video compression module, which has high image resolution (1.3 million pixels), compression ratio, the interface is simple and so on, you can
