Patent

CA 2387701

The invention pertains to a method of temporal processing (Fig. 10) of motion picture image frames (100) each comprising a plurality of pixels, including the steps of comparing each pixel of a current frame (n) to at least one previous (n-1, n-2, ...) or subsequent image frame (n+1, n+2, ...); determining at least one motion vector (106) corresponding to each such pixel relative to such at least one previous or subsequent image frame; and saving the determined motion vectors; applying motion vectors corresponding to multiple image frames to define a new pixel for each pixel of the current frame, and outputting all of such new pixels as a constructed image frame.

La présente invention concerne un procédé permettant de traiter temporairement les trames d'images cinématographiques (100) constituées chacun d'une pluralité de pixels, et consistant à comparer chaque pixel d'une trame courante (n) à au moins une trame d'images précédente (n-1, n-2, ...) ou ultérieure (n+1, n+2, ...); à déterminer au moins un vecteur de déplacement (106) correspondant à chacun de ces pixels relatifs à cette trame d'images précédente ou ultérieure; à sauvegarder les vecteurs de déplacement déterminés ; à appliquer des vecteurs de déplacement correspondant aux trames d'images multiples pour définir un nouveau pixel pour chaque pixel de la trame courante, et à produire tous ces nouveaux pixels sous forme de trame d'images construites.
