VIDEO ENCODING DEVICE AND METHOD, AND VIDEO DECODING DEVICE AND METHOD

摘要

A video encoding device for subjecting an image to be encoded, which is contained in a video to be encoded, to prediction encoding. The present invention is provided with: a prediction means for predicting an image to be encoded by using an image that was already encoded as a reference picture, and for determining first reference information indicating a first reference region which is a reference destination; a second reference information determination means for determining second reference information indicating a second reference region, which is a different reference destination for the image to be encoded, from the reference information of the first reference region during prediction encoding; and a prediction image generation means for generating a prediction image on the basis of the second reference information or on the basis of the first reference information and the second reference information.
