在這篇論文當中我們將利用CMOS 0.18um 製程來製作數位式影像感測器，使用CMOS製程可便於與其他應用電路整合在一起，以達到降低成本與減少功率消耗。此外，利用數位式的影像感測器所具備高速取像的能力，可以有更多的應用。
影像感測器的動態範圍是為最大未飽和訊號與最小可偵測訊號的比值，在影像感測器中是一個優缺的重要指標。而在這篇論文中我們提出一個新的演算法來增加動態範圍，此演算法改良許多過去增加動態範圍演算法的缺點，使得這個影像感測器系統可擁有高動態範圍與高速取像的能力。

In this thesis we intend to develop a digital image sensor by using CMOS 0.18 um technology. The main reason of using CMOS technology lies in the compatibility with other circuit, which can lead to low cost and low power dissipation. Besides, digital pixel sensors can offer many applications if they are capable of high speed imaging.
Dynamic range is the ratio of the largest non-saturating signal to the smallest detectable signal, which is a critical figure of merit for image sensor. In this thesis we will also propose a new algorithm to increase the dynamic range. This new algorithm is an improvement of the past improve-dynamic-range algorithm. With this algorithm, a imaging system will have the ability of capturing high dynamic range image and high speed capturing.
