Claim One:
1. A method for reducing blurring in a blurred image, the method comprising the steps of: creating an edge mask from the blurred image; providing an extended initial array; extending the edge mask; performing Lucy-Richardson iterations, with masking using the extended edge mask and the extended initial array to create a deblurred image, the step of performing Lucy-Richardson iterations with masking including computing f ( k + 1 ) â¡ ( n ) = Î² â¡ ( n ) â¢ ( âˆ‘ m â¢ h â¡ ( m , n ) â¢ M â¡ ( m ) â¢ g â¡ ( m ) g ( k ) â¡ ( m ) ) â¢ f ( k ) â¡ ( n ) wherein f represents a sharp image, M is the edge mask, Î² is a mask, h is a known point spread function, g is the blurred image, and m,n denote positions of elements within a two dimensional pixel array of the blurred image; and cropping the deblurred image to remove the extended portions of the deblurred image.
