Abstract
Compared to conventional intra divided-picture encoding, deterioration in the coding efficiency is suppressed and the encoding computational complexity and the decoding computational complexity are reduced. A divided picture generating unit divides an input encoding target picture into blocks of the same size and generates divided pictures having the same size by collecting pixels having the same relative position within each block. An intra divided-picture encoding processing unit performs intra divided-picture encoding on part of the divided pictures. An inter divided-picture encoding processing unit performs inter divided-picture encoding using another encoded divided picture as a reference picture. When there are a plurality of candidates for the reference picture, a correlation direction calculating unit obtains a combination in which a correlation of a pixel on an original picture is high among combinations of encoded divided pictures and their reference pictures. A reference picture selecting unit selects an encoded divided picture in a direction in which a correlation with an encoding target divided picture is high as the reference picture to be used in the inter divided-picture encoding processing unit.
