摘要

在這篇論文裡，我們提供了在RGBW色彩濾波矩陣上的一個色彩內插演算法。
這個方法只需要少量的運算並且減少了色彩失真的問題。
首先我們會先介紹傳統色彩內插演算法，接著會描述由以上演算法所造成的色彩失真問題，並且在第三章介紹我們提供的方法，還有解釋我們如何改善色彩失真。
在第四章裡，會先介紹何為峰值信噪比 (PSNR)，並且我們會利用PSNR和內插處理時間比較不同色彩內插演算法和我們的演算法之間的差異。
最後，我們會提到不同演算法跟我們演算法之間的優缺點還有在未來可以加強的方向。

In this thesis, we propose a novel interpolation on RGBW color filter array.
Moreover, this method reduces the problem of color-alias and requires low computation.
We introduce the background first, and review some traditional interpolation schemes.
Then we discuss some problems in color interpolations such as edge-blurred and color-alias effects.
Next, we will explain our proposed method in Chapter 3, and show the results in Chapter 4.
We will compare different interpolations on Peak Signal-to-Noise Ratio (PSNR) and processing time.
Last, conclusion and future works will be presented in Chapter 5.
