Claim:
1. A moving image decoding apparatus for decoding moving image data that is encoded such that a clean region, which includes at least one block that is encoded such that a pixel value is guaranteed to be decoded correctly, occupies an entire picture in a predetermined cycle, the moving image decoding apparatus comprising: a processor configured to decode the decoding target block with reference to only referenceable blocks by executing a filter process of applying a predetermined filter to the reconstructed decoding target block, including, when pixels in the unreferenceable blocks are included in a region which the predetermined filter references, calculating first decoded data to be used to decode another block, by executing the filter process after replacing values of the pixels in the unreferenceable blocks by a value of any of pixels in the referenceable blocks in the region which the filter references.
