Abstract

Recently, a color filter array sensor with the white channel has been developed. This color filter array differs from the Bayer CFA, which is composed of red, green and blue channels. Since the white channel shows high sensitivity through broad spectral bands and a high light sensitivity, it presents many advantages. However, various color interpolation method for the Bayer CFA cannot be utilized for CFA pattern that contains the white channel directly. In this paper, a method for generating a quincuncial pattern is proposed for the CFA pattern. By generating an intermediate quincuncial pattern, various color interpolation algorithms can be applied to it. Experimental results are shown in comparison with the conventional method in terms of PSNR measurements.
