Abstract: The process consists in estimating motion by execution of a gradient algorithm (2, 3) which brings to a minimum the mean square deviation of the local variations of the current point of the image with the point that is homologous to it in the preceding image, in initializing (7) the execution of the algorithm by the displacement values estimated in several directions within the close vicinity of the current point and by an initial vector of temporal prediction of the displacement between successive frames of the image, then in propagating each estimation in the direction of scanning of the lines of the image.

Abstract: A process, and a corresponding device, for temporal image interpolation with corrected movement compensation, respectively use a consistency analysis step or circuit to analyse the defects in a field of movement which results from the movemenet estimation process step or device to perform either compensated-movement interpolation, or linear interpolation, depending whether the field of movement is estimated to be corrected or defective for the current point of the frame to be interpolated. Preferentially, to avoid abrupt transition between the two modes of interpolation, a process step or circuit enables intermediate values to be found which take into account the two modes of interpolation in the transition zones.
