Abstract
A method and apparatus to restore images degraded by motion or vibration as characterized by the measurement of the relative motion between the object and the imaging device, calculation of the Optical Transfer Function (OTF) from the Line Spread Function (LSF), and applying a restoration filter M according to the following rule ##EQU1## where H is the image motion OTF, C is the discrete Laplacian operator which is used to minimize the error and .gamma. is the convergence parameter of an iterative algorithm.
