Abstract
The present invention provides a motion vector estimation apparatus which can decrease circuit size by reducing the amount of computations for detecting a motion vector. The motion vector estimation apparatus in the present invention includes a motion vector estimation unit which estimates a motion vector MVF for the target block BLby searching within a reference picture Pfor a block with an image similar to an image in the target block BL, which is included in a picture B; a prediction calculation unit and a prediction range control unit which specify a search range in the reference picture Pbased on the motion vector MVF and; the motion vector estimation unit estimates the motion vector MVF for the target block BLby searching in the search range for a block with an image similar to an image in the target block BL, which is included in the picture B
