This paper investigates an issue of the modified Bayer pattern color filter array (CFA). A demosaicking algorithm is considered as a color super-resolution approach, which is widely used in digital camera industry and employed to reconstruct a full color (three-channel) images from existing one color component with missing two color components. In a pair of Bayer pattern CFA, there are two green pixels and one red pixel and one blue pixel exist. We consider this format as RGGB. However, there could be alternatives such as RRGB or RGBB formats. In this paper, we investigate the effect of three CFA scenarios. Experimental results show that the obtained filters provide satisfactory performance.
