Claim One:
1. An image enhancement apparatus for enhancing an input image of a sequence of input images and obtaining an enhanced output image, said apparatus comprising: a motion compensation unit configured to generate at least one preceding motion compensated image by compensating motion in a preceding output image, a weighted selection unit configured to generate a weighted selection image from said input image and said preceding motion compensated image, both being weighted by a respective selection weighting factor, a feature analysis unit configured to analyse at least the input image and to generate feature information by segmenting the input image into two or more input image regions having different features, an image model unit configured to generate a modelled image by applying an image model, in particular a Huber Markov image model, on said input image and/or said weighted selection image, a spatio-temporal detail signal generation unit configured to generate a detail signal from said input image and said weighted selection image, and a combination unit configured to generate said enhanced output image from said input image, said detail signal and said modelled image.
