FIELD: physics, video.;SUBSTANCE: invention relates to a motion vector estimation method and a multiview video encoding and decoding method. The motion vector estimation method includes: a view synthesised picture generation step of generating, from a reference camera video, a view synthesised picture at a time when the processing picture was been taken; and a corresponding region estimation step of estimating a motion vector by searching for a corresponding region in a reference picture taken by the processing camera using a picture signal on the view synthesised picture corresponding to a processing region on the processing picture without using a processing picture taken at a time at which a motion vector is to be estimated.;EFFECT: accurate motion vector estimation and realising efficient multiview video encoding.;22 cl, 20 dwg
