Abstract
An image decoding device includes an illumination compensation flag derivation section that derives an illumination compensation flag indicating whether illumination compensation is executed and an illumination compensation section () that generates a predicted image of a target prediction unit using illumination change parameters derived from an image in a neighbor of the target prediction unit on a target image and a reference region image of a reference image corresponding to the target prediction unit in a case where the illumination compensation flag is a value indicating validity. In a case where a prediction unit which is a generation target of the predicted image is in a merge mode, the illumination compensation flag derivation section decodes the illumination compensation flag from coded data.
