METHOD AND DEVICE FOR IMAGE INTERPOLATION WITH MOTION COMPENSATION

A method of interpolating images intended to be incorporated, into a sequence of moving images, each between a first original image and a second original image of the sequence, comprises an estimation of a motion vector associated with a given pixel block of a current interpolated image. This estimation comprises the preselection of P first motion vectors associated with first other pixel blocks that are adjacent to the given pixel block in the current interpolated image, for which there is already an estimated motion vector. It also comprises the preselection of at most Q second motion vectors associated respectively with second other pixel blocks adjacent to the given pixel block in the preceding interpolated image. Finally, it comprises the selection of the motion vector which minimizes a cost function from the first and second preselected motion vectors.
