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 determined images. Each image is divided into pixel blocks and a motion vector is associated with each block of a processed image. Motion vectors associated with respective blocks of the image are processed and motion vectors associated with respective blocks of a preceding processed image (spatial and temporal motion vectors) are selected with respect to a current block of an image being processed. Candidate motion vectors are generated from the motion vectors selected. One vector is elected from among the candidate vectors. Information associating the elected vector with the block is stored. A temporal motion vector is selected only if it satisfies a determined selection criterion based on the orientation of the motion vector.
