    • 隨著全球社會人口年齡分布趨向老人化，及現代人少子化的觀念，老年人的人口比例日益漸增，長者的日常生活環境愈也來越受重視，其中尤以獨居老人的居家安全更為被大眾廣泛的討論及研究。本文提出一個完全嶄新的偵測概念-區域獨立影像處理系統（CIIP system），其係將無線可攜式針孔攝影機配戴於使用者身上，並利用簡單的影像處理演算法，便可成功有效的偵測獨居長者之跌倒甚而昏迷的狀態。將此系統合併識別標籤後，便可達到判別使用者所在位置之目的。最後，文中提出一個全新的影像訊號處理技巧-像素值累積法（pixel value accumulation method），藉由這個方法合併相關係數運算（cross correlation）與其他簡易的影像處理技巧，可在區域獨立影像處理系統中，識別出受偵測者之簡單移動行為。

    Because the population distribution of global societies is toward aging and the trend of fewer children born in the present generation, the percentage of elders will be higher and higher in the future. At the same time, in order to improve the life quality of elders, many researchers have paid much attention on the study of smart home to provide various techniques in equipping the environment with more capability to help elders in various ways. The regular life safety of elders who live alone is especially discussed, investigated and researched widely. A novel detection conception－content-independent image processing system (CIIP system) is designed and suggested in this study. The falling behaviors and unconscious situations of aged people can be identified successfully and effectively by putting and fixing a wireless mini camera on users and taking advantage of several simple digital image processing skills. Combining this proposed system with color markers, the goal of locating user’s position is achieved. Lastly, a whole new image signal processing manner－pixel value accumulation method is created and recommended in this thesis. Merging this method with the cross correlation operator and other common image processing techniques, uncomplicated movements of users can be identified in CIIP system.
