An image decoding device which decodes an encoded stream of images each divided into plural units. The image decoding device including: a parameter candidate generating unit configured to generate a parameter candidate list including one or more parameter candidates each of which is available to decode a decoding target unit, using one or more parameters used in decoding of one or more decoded units; a parameter information decoder which decodes parameter information included in the encoded stream and related to the one or more parameter candidates; and an error detecting unit configured to detect, as an error, a state in which the parameter information decoded by the parameter information decoder does not have a match in the parameter candidate list generated by the parameter candidate generating unit. |
