Abstract:	隨著網路世界快速的發展，網路的頻寬越來越大，傳送資料的速度也越來越快，網路攝影機成為數位家庭化中的熱門產品。利用網路攝影機可以讓使用者在任何時間、任何地點觀看家中的情況。為了有效的利用網路的頻寬，必須將影像做有效的壓縮編碼，以避免當網路壅塞的時候還是可以在最短的時間內將影像資料傳送至使用者端。一般目前在IP Camera系統上最常見的壓縮編碼方式為M-JPEG與MPEG-4。而M-JPEG雖然所支援的壓縮率較低，但相對擁有硬體需求較低和價格上的優點，因此本系統選擇使用M-JPEG的IP Camera系統來進行圖片壓縮編碼，加上影像偵測與追蹤演算法追蹤特定的移動物，以應用於網路攝影機的影像追蹤上。若家中有需要照顧的老人或小孩，可以在居家中建構幾個網路攝影機，鏡頭會隨著目標物移動，改善傳統攝影機只能提供單調拍攝的缺點；對居間環境更能提供多一份的安全監控，落實以科技改善生活的理念。 According to the rapid development of the internet world, the network bandwidth and the transit speed have been rising up by degrees, which make the “IP-Camera” become the most popular product in digital family. The IP-Camera can make the users watch the situation at home anytime. In order to use the network bandwidth efficiently, the images must be compressed and encoded together so that they can be transited to the end-users successfully at internet obstructing time. In general, the common methodology ways in the IP Camera system are M-JPEG and MPEG-4. Although the compression rate of M-JEPG is much lower, it still has the advantages of lower hardware request and flexible price. As a result, we choose the IP Camera and its compression engine is M-JPEG to process our image processing and add the image detection and tracking algorithm to track the specific object in accordance with the application of IP-Camera. Therefore, the IP-Cameras can be set up at home to observe the elders and children who need help and improve the drawback of the monotonous shoot of tradition camera, which can offer another safe guard in family and realize the dream of making our life better by modern technology.
