Abstract

A picture encoding method in which a picture constituting a motion vector is divided into an object picture in which the main concern is a picture making up the moving picture and the other picture, the object picture is further divided into a texture picture representing brightness and color hue of the picture and a shape picture representing the shape of an object and the texture and shape pictures are respectively encoded. The motion vector of the shape picture is detected to output the motion vector of the shape picture, and the shape picture is encoded based on the motion vector of the shape picture to output encoded data of the shape picture. The motion vector of the shape picture is encoded to output encoded data of the motion vector of the shape picture, and the motion vector of the texture picture is decoded, using the motion vector of the shape picture, to output the motion vector of the texture picture. The texture picture is encoded based on the motion vector of the texture picture to output encoded data of the texture picture and the motion vector of the texture picture is encoded using the motion vector of the shape picture to output encoded data of the motion vector of the texture picture. This improves the encoding efficiency while facilitating decoding control.
