IMAGE PROCESSING APPARATUS, IMAGE RESTORATION METHOD AND PROGRAM

摘要

An image processing apparatus is provided which executes image restoration processing by performing a iterative computation on a degradation image. The image processing apparatus is capable of maintaining the quality of a restored image and completing the iterative computation sufficiently quickly. The first image restoration processor creates a first restored image f 1 for a degradation image g by calculating an inverse filter H^-1 based on Fourier transform H of a deterioration function h, multiplying the inverse filter H^-1 and Fourier transform G of the degradation image g, and performing inverse Fourier transform on the result of the multiplication. The second image restoration processor creates a second restored image f 2 by a iterative computation using the first restored image f 1 and the deterioration function h.
