Claim One:
1. An image restoration method in a system having an image sensor and a digitizer, comprising the steps of: (a) providing an imaging system described by an integral operator P; (b) transmitting an ideal image f(x,y) through an image blurring and degrading transmission medium to provide a degraded image g(x,y) wherein the degraded image g(x,y) may be represented as Pf=g; (c) receiving said degraded image g(x,y) from said transmission medium by said image sensor; (d) digitizing said degraded image g(x,y) by said digitizer; (e) transforming said degraded image g(x,y) to provide a time modified representation w(x,y,t)=P.sup.t f wherein w(x,y,0)=P.sup.0 f represents the ideal image f(x,y) at time t=0 prior to the operation of the integral operator P upon f and w(x,y,1)=Pf=g represents the degraded image g(x,y) when the image is received by said image sensor; (f) requiring the magnitude of the difference between the ideal image f and a blurred version of f to be less than a preassigned tolerance value by minimizing .parallel.f-P.sup.s f.parallel. wherein P.sup.s f represents an image at time t=s as s approaches 0; (g) determining a plurality of values of w(x,y,t) in accordance with said minimizing; (h) adjusting said image in accordance with said determined plurality of values to provide a plurality of adjusted images; (i) selecting an adjusted image of said plurality of adjusted images; and (j) displaying said selected image.
