The color image enhancement is an important topic for last few decades and still many researchers are working and presenting their research findings in literature. There are two issues in digital camera, firstly color filtering and secondly low spatial resolution. To solve both issues, this paper presents a new super resolution approach. Although Bayer pattern CFA is widely used in camera industry, there are few alternatives such as X-Trans CFA pattern. As color restoration method for X-Trans CFA pattern is not many, this paper introduce filter based demosaicking method. We firstly design filters then apply it to X-Trans CFA pattern. Then, full color images are obtained. Experimental results indicate that the presented method provides satisfactory results.
