METHOD FOR THE REPRESENTATION OF VIDEO IMAGES OR SCENES, IN PARTICULAR AERIAL IMAGES TRANSMITTED AT REDUCED FRAME RATE

A method and an apparatus for the representation of video images or scenes, in particular aerial images with a relative movement between a pick-up sensor and the scene transmitted at reduced frame rate. Intermediate frames are reconstructed to be inserted between two transmitted frames, said reproduction starting from a small number of distinct corresponding reference points in the two transmitted frames, said reference points being situated in different vertical and horizontal coordinates within each of said two transmitted frames, and being determined by correlation of image point location within said transmitted frames calculating for each picture element in said intermediate frames the locations of the corresponding picture elements in each of said two transmitted frames and determining the value of the intensity for each picture element of said intermediate frame by interpolation and/or extrapolation and issuing said value. One of said two transmitted frames can be represented as a still picture for a certain period of time followed or preceded by a series of reconstructed intermediate frames providing a moving picture.
