摘要

There is provided a technique that includes a triangle merging candidate list constructor structured to construct a triangle merging candidate list including spatial merging candidates, a first triangle merging candidate selector structured to select, from the triangle merging candidate list, a first triangle merging candidate that is uni-prediction, and a second triangle merging candidate selector structured to select, from the triangle merging candidate list, a second triangle merging candidate that is uni-prediction, in which in a region 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 one of the first triangle merging candidate or the second triangle merging candidate is saved.
