Document Type and Number:
WIPO Patent Application WO/2011/122659
Kind Code:
A1
Abstract:
A moving image decoder apparatus comprises: a block scan unit (141a) for classifying blocks into non-skip blocks in each of which a code obtained by encoding a parameter related to the block is included in encoded data (#13) and skip blocks in each of which that code is not included in the encoded data (#13); an mv decoding unit (141e) for setting a motion vector (mv) related to each non-skip block to a value obtained by decoding the corresponding code included in the encoded data (#13); and a skip mv estimating unit (141f) for deriving the mv related to each skip block with reference to the value of a parameter set by the mv decoding unit (141e) that is the value of a parameter related to the non-skip blocks preceding and following in the raster scan order.
