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.

An inverse discrete cosine transform apparatus has operation units for operating a combination of plural basic operation matrixes, including rearrangement, addition, subtraction and multiplication. A coefficient C of multiplication is defined as C=cos (n.pi./16) (n:integer), and the basic operation matrixes are represented by equation (6), and operations of matrixes of addition and subtraction are carried out prior to operations of respective matrixes of multiplication.

A method of controlling the selections on a reproducible control data structure with two different selection control methods. According to a first control method, single frame plural selectors, to each of which a numerical identifier has been added, are displayed. Branch tables grouping branch data according to selector numbers are provided. A user makes a selection by selecting a selector number. According to a second control method, plural sectors are displayed in a single frame. A user-specified selector and other selectors are provided for visually differentiating between the selectors as a means of prompting user confirmation of the specified selector. A selection confirmed by the user controls the selection by means of the branch data. Branch data usable by both the first control method and the second control method is grouped together by providing the branch data used by the second control method in the branch table used by the first control method.
