The method is suitable for enhancement of images in a digital still camera; with in noise produced artifacts originating from high ISO noise. The enhancement process is split into three stages: demosaicing, denoising, and deblurring; and along this line we present an approach to enhance a high ISO-sensitivity image. Our approach firstly demosaics observed color data with the bilinear interpolation, which is robust against noise but causes blurs. Next, it applies color shrinkage to each wavelet coefficient or each grouplet coefficient of the demosaicked image, to produce a denoised one. Finally, it applies to the denoised image a color-image enhancement method corresponding to an extension of the universal sharpening-deosaicking method and employs the soft color-shrinkage. Our project produces a high-quality image even in an ISO-6400 case atiff UTM 74 p.
