Claim 10:
11. A three-dimensional data decoding device comprising:
a processor; and
memory, wherein
using the memory, the processor:
performs motion compensation on a plurality of decoded point clouds;
merges the plurality of decoded point clouds that have been motion compensated, to generate a reference point cloud;
performs entropy decoding of an N-ary tree structure of a current point cloud using the reference point cloud, and controls a probability parameter to be used in the entropy decoding, based on the reference point cloud, where N is an integer greater than or equal to 2; and
generates a decoded point cloud of the current point cloud from the N-ary tree structure of the current point cloud.
