概要	A monochrome-image iterative deblurring method with the classic soft-shrinkage in the shift-invariant Haar wavelet transform do-main was recently proposed by R. H. Chan et al. Extending this deblurring method, we present a new iterative sharpening-demosaicing method with the shift-invariant Haar wavelet trans-form and our color shrinkage utilizing redundant color transform. Our new sharpening-demosaicing method is originally constructed for the Bayer’s primary color-filter array (CFA), but its minor modification renders it applicable to various CFA’s other than the Bayer’s CFA: the complementary CFA, the random arrangement CFA, and so on. Simulation results demonstrate that our new sharpening-demosaicing method in the shift-invariant Haar wave-let transform domain works much more efficiently than our previ-ously proposed sharpening-demosaicing method with the total-variation regularization in the spatial image-domain.
