发明名称 PROCESSO E DISPOSITIVO DE INTERPOLACAO TEMPORAL DE IMAGENS COM COMPENSACAO DE MOVIMENTO CORRIGIDA
摘要 The method, and the corresponding device, for temporal interpolation of pictures, with corrected movement compensation according to the invention performs, via a coherence analysis circuit (40), an analysis of the defects in the field of movement which is output by the movement estimation device (10) in order to perform either the compensated movement interpolation (20) or a linear interpolation (30), depending on whether the field of movement is estimated to be correct or defective for the current element of the frame to be interpolated. Preferably, in order to avoid abrupt switching between the two modes of interpolation, a circuit (50, 60) enables intermediate values to be found taking into account the two modes of interpolation in the transition zones. <??>The invention applies, in particular, to standard conversion. <IMAGE>
