  • Method for the representation of video images or scenes, in particular aerial images transmitted at reduced frame rate
    Patent number: 4710809
    Abstract: The invention relates to a method for the representation of video image sequences or scenes with a relative movement between a pick-up sensor and the viewed scene, such scenes being transmitted at reduced frame rate. By interpolation and/or extrapolation on the basis of two transmitted frames intermediate frames are generated on the receiving end of the transmission line and inserted into the transmitted frame sequence. The positions of image points (pels) which are identical in the two transmitted images are determined from the relationship of the pel positions for at least two identical pels on different vertical and horizontal coordinates in each of the two transmitted frames. Before reconstruction of the intermediate frames the mean brightness values for limited picture areas which represent the environment of at least one of the corresponding pels in two successive transmitted frames are determined.
