IMAGE DECODING DEVICE AND IMAGE CODING DEVICE

摘要

A hierarchical moving image decoding device (1) includes an inter-layer reference image list setting section (155) that derives an inter-layer reference image list and an inter-layer reference image set used in pictures on a specific target layer based on a parameter set of a target layer.

1. An image decoding device that restores a decoded image of a higher layer using coded data of the higher layer included in coded data that is hierarchically coded, the image decoding device comprising:
a variable-length decoding circuit that decodes a parameter set from the coded data of the higher layer; a base decoded image buffer that retains a decoded image of a lower layer in association with a picture display order of the higher layer derived from the parameter set; a base control circuit that retains an image decoded by an external device in the base decoded image buffer; and an inter-layer image prediction circuit that generates a predicted image through inter-layer prediction using a decoded image of the lower layer.
