<p>An image decoding apparatus (100) capable of appropriately executing parallel decoding processing by a simple structure includes: a stream segmentation control unit (140) that designates a processing target area, and selects a portion of a segment stream based on a position of the processing target area; M stream segmentation units (130) that generate M x N segment streams by executing stream segmentation processing on designated M processing target areas in parallel; and N decoding engines (120) that decode respective portions of the N segment streams including the selected portion in parallel. In the case where a slice included in the processing target area is segmented into a plurality of slice portions and assigned to a plurality of segment streams, each stream segmentation unit (130) reconstructs, for each segment stream, a slice portion group made up of one or more slice portions assigned to the segment stream, as a new slice.</p> |
