    • A segment allocation determination unit of an image decoding device determines an allocation of segments, in accordance with processing capabilities of the image decoding units, so that the processing times of the image decoding units are equal. When a first error detection unit detects an error, a segment allocation determination unit performs control so that the segment including the error is allocated to an image decoding unit to which a predicted reference image of the segment is allocated. When any of second error detection units detect an error, the segment allocation determination unit controls allocation of the next series of segments with consideration to a bit amount skipped due to the error. This enables providing an image decoding device that can efficiently realize decoding with a plurality of image decoding units even when an error is detected.
    • 图像解码装置的片段分配确定单元根据图像解码单元的处理能力确定片段的分配,使得图像解码单元的处理时间相等。 当第一错误检测单元检测到错误时,段分配确定单元执行控制,使得包括错误的段被分配给分配了段的预测参考图像的图像解码单元。 当第二错误检测单元中的任何一个检测到错误时,段分配确定单元考虑到由于错误而跳过的位数量来控制下一系列段的分配。 这使得即使在检测到错误的情况下,也能够提供能够与多个图像解码单元有效地实现解码的图像解码装置。
