Abstract: A motion estimation method and device are provided for processing images to be inserted, between a preceding original image and a following original image, into a sequence of images. Each image is divided into pixel blocks associated with motion vectors. For a current block of an image being processed, motion vectors associated with blocks of the image being processed and/or associated with blocks of a processed image are selected. Candidate vectors are generated from selected motion vectors. An error is calculated for each candidate vector. A penalty is determined for a subset of candidate vectors on the basis of the values of the pixels of the pixel block in the preceding original image from which the candidate motion vector points to the current block and/or on the basis of the values of the pixels of the pixel block in the following original image to which the candidate motion vector points from the current block.
