摘要： A picture processor including a picture-deformation-information input section for inputting the information for the degree of enlargement/contraction of each portion of a picture; a decoding section for inputting encoded picture data of the picture, inputting the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, decoding the picture data every portion of the picture in accordance with the information for the degree of enlargement/contraction, and moreover decoding the whole picture data independently of the information for the degree of enlargement/contraction; a reference picture generation section for generating a reference picture enlarged or contracted for each portion of the picture by using a picture in which the whole picture data is decoded supplied from the decoding section, the information for the degree of enlargement/contraction of each portion of the picture from the picture-deformation-information input section, and the movement vector of the picture data; and an addition section for adding a picture decoded for each portion of the picture supplied from the decoding section and a reference picture supplied from the reference-picture generation section.
