Abstract

Colour images progressively blurred by defocusing and by chromatism of optical systems are restored by digital techniques. The Fourier transforms for the green, blue and red image components have been degraded by the respective three components of the polychromatic transfer function computed from the wave aberration. The effects on the image for several amounts of aberration as well as the degree of restoration obtained by different Wiener filtering for each colour component are shown.
