Abstract
An image deteriorated by camera shake, or the like, is restored in a short period of time. A ∇J computation section computes an evaluation value J from a deteriorated image G captured by means of photographing, a restored image F, and a PSF computed from an angular velocity detected by an angular velocity sensor, and further computes ∇J. When the square of norm of ∇J exceeds a threshold value, there is iterated processing for computing a new, restored image F by means of subtracting ε·∇J from the restored image F. A convergence parameter computation section sets the convergence parameter ε as a value which first shows an increase and subsequently a decrease depending on the number of iterations, thereby increasing the speed of convergence and inhibiting divergence.
