According to the present invention in the case of multiresolution decomposition performed on the color components of image data using an orientation selective wavelet frame or an orientation selective filter bank acquisition of sub band signals and reconstitution of the image by adding together the acquired sub band signals between the decomposition phase of multiresolution decomposition and the synthesis phase a coefficient process is performed on the decomposition detail coefficients output from the decomposition phase doing so in such a way that small values are kept smaller the greater the energy of the decomposition detail coefficients in question while small values are enhanced the lower the energy of the decomposition detail coefficients in question. Alternatively the coefficient process may be performed in the opposite manner.
