Abstract
In the field of optical systems comprising at least one optical objective, a photosensitive detector and an image processing unit, the optical objective comprising a pupil encoding filter, the image processing unit performing digital filtering of the images output by the photosensitive detector, a system has a processing unit comprising means arranged in such a way as to process at least one preset, the characteristics of the digital filtering applied to the image depending on this preset. The preset may come from external sensors of temperature and/or pressure or be one of the parameters of the optical objective such as the focal length value, the aperture of the iris, or the desired focal distance. The preset can also be different for different zones of the image, to better take into account the variations of the aberrations in the field of the focusing objective.
