Abstract

A broadband white-light processing technique for smeared color photographic image deblurring is described. The technique utilizes a diffraction grating method to disperse the smeared image spectra in the Fourier plane so that the entire spectral band of the white-light source can be utilized for the deblurring. In this paper the technique of synthesizing a fan-shape type complex deblurring filter to accommodate wavelength variation is presented. Experimental results showed that this broad spectral band processing technique offers an excellent coherent artifact noise suppression, and the technique is particularly suitable for color image deblurring. Experimental demonstrations and comparisons with the narrowband and coherent deblurring are also provided.
