5. A moving picture decoding method using a triangle merge mode, the moving picture decoding method comprising:
a triangle merging candidate list constructing step for constructing a triangle merging candidate list including spatial merging candidates;
a first triangle merging candidate selecting step for selecting, from the triangle merging candidate list, a first triangle merging candidate that is used for uni-prediction partition 0 which consists of subblocks above a diagonal line of the triangle partition splitting a coding block; and
a second triangle merging candidate selecting step for selecting, from the triangle merging candidate list, a second triangle merging candidate that is used for uni-prediction partition 1 which consists of subblocks below the diagonal line,
wherein in uni-prediction partition 0, uni-prediction motion information of the first triangle merging candidate is stored and
in uni-prediction partition 1, uni-prediction motion information of the second triangle merging candidate is stored and
in bi-prediction partition 2 which consists of subblocks on the diagonal line where motion compensation by weighted averaging by the first triangle merging candidate and the second triangle merging candidate is performed, uni-prediction motion information of the second triangle merging candidate is stored in a coding information storage memory so that the uni-prediction motion information of the second triangle merging candidate can be referred to as inter prediction information neighboring the coding block without storing bi-prediction motion information which is converted from motion information of list L0 and motion information of List L1.
