近年來，許多文獻提出對數響應較符合人眼的特性，而影像感測器的動態範圍是為最大未飽和訊號和最小可偵測訊號的比值，在影像感測器中是一個重要的參數。因此具有高動態範圍並且具有對數響應的影像感測器是許多人研究的目標，然而為了完成以上的目標，往往須增加硬體複雜度。
在本論文中，在數位畫素感測器的架構中，提出新的多重取樣方法，其畫素的輸出為數位的格式，所以使得畫素具有較高的讀取速度。此新的多重取樣方式具有高動態範圍、具有近似對數響應、降低硬體複雜度和高速取樣的能力的優點。本架構也提供了供使用者在不同的光照環境下選擇不同的模式，另外本論文也對多重取樣會產生的編碼遺失提出解決方法。

Recently, many papers proposed the characteristic of the logarithmic output response was suitable to human eye’s sensitivity. 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. Hence the COMS image sensor which has high dynamic range and logarithmic output response are many people’s objectives. But in order to complete the above objectives, the complex of the hardware often increase.
In this thesis, we propose a novel multiple sampling scheme based on the architecture of the digital pixel sensor (DPS). The output from the pixel is digital format. This will lead to very high readout speed. This novel sampling scheme has the advantages of high dynamic range, logarithmic output response, lower complexity of the hardware and high speed capturing simultaneously. The scheme also provides different modes for user in the varied environment. Besides this paper also bring up the solving method for miss-coding with multiple sampling.
