In this paper, we propose a demosaicking method that uses a correlation between the wavelet subband coefficients in the high frequency region of color channels (R, G and B). In this paper, we introduce the pre-existing demosaicking methods, and show that our proposed method yields an outstanding performance through in imitation tests compared to pre-existing methods in terms of objective performance and subjective resolution.
