摘要

An object of the present invention is to perform encoding and decoding at a high compression rate even with a video consisting of a mixture of pictures of different bandwidths. In a video encoding device 10, a predicted signal generator 121 extracts spatial frequency components in a predetermined band from a predetermined extraction reference picture except for a target reference picture used as a picture for prediction of a target picture as an object to be encoded, among reference pictures stored in memory 108. The predicted signal generator 121 generates a predicted signal for the target picture from the target reference picture and the extracted spatial frequency components.
