Image restoration and digital image processing are foundations for data analysis of ground-based solar observations. Image restoration has to be defined in this context. Whereas image enhancement strives to bring out certain features in an image to simplify the extraction of image information, image restoration is the attempt to retrieve information that has been lost or obscured in the imaging process itself. Therefore, image restoration requires a systems approach that takes into account the entire process of image formation including the propagation of light through inhomogeneous media, the properties of the optical system, and the characteristics of the detector. Here, solar astronomy in general and observations with the Vacuum Tower Telescope and GREGOR solar telescope in particular – both at Observatorio del Teide, Tenerife, Spain – will serve as an example of the image formation process. Various image restoration methods and the underlying mathematical models will be introduced and discussed.
