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.
