1: An image decoding device which decodes coded data obtained by coding image information, comprising:
profile information decoding means for decoding profile information; level information decoding means for decoding level information; sublayer profile present flag decoding means for decoding a sublayer profile present flag (sub_layer_profile_present_flag) indicating the presence or absence of sublayer profile information regarding respective sublayers; and sublayer level present flag decoding means for decoding a sublayer level present flag (sub_layer_level_present_flag) indicating the presence or absence of sublayer level information regarding the respective sublayers, wherein the profile information decoding means refers to decoded sublayer profile present flags of the number of sublayers−1 and, in a case where the sublayer profile information is present, decodes the sublayer profile information, and wherein the level information decoding means refers to decoded sublayer level present flags of the number of sublayers−1 and, in a case where the sublayer level information is present, decodes the sublayer level information. |
