中文摘要：

介绍一种自主研发的高速计算机屏幕信息记录系统。该系统支持VGA／DVI输入，支持SVGA、XGA、SXGA、UXGA等多种计算机屏幕分辨率图像的连续压缩和存储。实验表明，本系统的单帧图像压缩性能接近JPEG2000标准，PSNR值优于JPEG标准。

英文摘要：

A high speed computer screen recorder system based on FPGA＋ARM is introduced in this paper. This system could support image signal from both DVI and VGA interfaee, and compress computer screen images with common resolutions, like SVGA, XGA, SXGA and UXGA. The experimental results show that the compression quality （PSNR） of this system could approach JEPG2000 standard and far better than JPEG standard.
