Abstract
In an image processing apparatus for performing image restoration by utilizing iterative calculations based on a captured degraded image and a degradation function obtained in or before photographing, a residual is calculated in each time of iteration in the iterative calculations and the rate of variation from the previous residual to the newly obtained residual is calculated. When the rate of variation of the residual becomes equal to or lower than a predetermined threshold value, it is judged that the iterative calculations are converged.
