Known defects in a given imaging situation, such as [[defocus]] or [[optical aberration|aberration]]s, can sometimes be mitigated in whole or in part by suitable spatial-frequency filtering of even a single image. Such procedures all stay within the diffraction-mandated passband, and do not extend it.
