PURPOSE: An image encoding/decoding device is provided to encode/decode a chrominance block according to a decoding mode determined by considering decoding modes/motion vectors of more than one luminance blocks. CONSTITUTION: A luminance block decoding unit decodes a luminance block according to a luminance decoding mode of each luminance block. A chrominance block decoding unit decodes a chrominance block corresponding to the luminance block using one of the plurality of decoding modes related to the luminance decoding mode of the luminance block. A plurality of chrominance decoding modes include a decoding mode not the same as the decoding mode the same as the luminance decoding mode of the luminance block. [Reference numerals] (1410) Decode motion information; (1414) Is there any motion information ?; (1416) Inter-decode luminance blocks; (1418) Analyze the motion information; (1420) Is the current mode an intra mode ?; (1422) Decode the luminance blocks in the intra mode; (1424) Are more than half of the luminance blocks being in an inter mode ?; (1426) Decode chrominance blocks in the intra mode; (1428) Decode chrominance blocks in the inter mode; (1430) Have all the blocks of a macro block been decoded ?; (AA) Start; (BB,DD,GG,HH,KK) No; (CC,EE,JJ,LL) Yes; (MM) End |
