A blind deconvolution method is proposed for restoring a diffraction-limited object from a convolution image with a band-limited PSF. The method is based on conjugate-gradient minimization of an error metric defined in this paper. An image restored with the proposed method always satisfies nonnegativity constraint. The performance of the method is investigated by computer simulation.
