FIELD: physics.

SUBSTANCE: image encoding device that divides the images into several areas to perform encoding for each divided area and performs hierarchical encoding for the images with a plurality of layers constituting the moving image that contains the first forming unit that forms the second image corresponding to the second layer different from the first layer; a coding module of any of the first image and the second image; the second forming unit that generates information indicating, whether there is the first independent area in the first image that is constrained so that it does not refer to another area in the first image; and the second independent area indicating unit that is limited so that it does not access another area in the second image at a position corresponding to the first independent area in the second image if the first independent area exists in the first image.

EFFECT: providing the ability to indicate a fragment that allows independent coding and decoding in hierarchical coding.
