Nowdays,the infrared camera in our country can export video signal and digital image signal. The video signal can display on the screen through the general grab card, but the digital one can not be inputted into computer without special image grab card. In this paper, an infrared image grab card and the correlative program driver are designed based on the analysis of the universe technology.

目前的国内的红外热像仪能够输出一组视频信号和数字图像信号，虽然视频信号能够通过普通采集卡在监视器显示，但是输出的数字图像信号不能直接输入到电脑上进行处理。

Decoded video signal is placed into frame buffer to capture video signal, decode or detect motion under the control of DSP, then detected image and motion results are transmitted by S3C4516 to guarantee visit of embedded video surveillance system via internet from client.

解码后的视频信号被放入帧缓存中，在DSP的控制下进行信号采集、编码或进行运动检测，然后由S3C4510B 将图像或运动检测结果进行传输，客户端可以通过网络访问本监控系统。

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering.

在本论文中，我们提出一个高频率倍数的全数位式锁相回路，此电路可应用於视讯系统中的时脉产生器，其主要功能是接收显示卡发出的水平同步讯号，并依据使用者设定的萤幕解析度，产生高频像素时脉来撷取视讯讯号资料，取样点的稳定度直接影响到显示画面的品质，若是像素时脉不稳定，则显示画面会闪烁或抖动。
