1. An image encoding apparatus comprising:
circuitry configured to:
shift, into a single encoding bounding box in a three-dimensional coordinate system of a point cloud, a first point cloud model and a second point cloud model apart from each other in the three-dimensional coordinate system, to make the first point cloud model and the second point cloud model closer to one another than before the shift;
generate transform information representing a parameter of the shifting;
project the first point cloud model and the second point cloud model, which are shifted in the single encoding bounding box, onto a plurality of projection planes of the encoding bounding box to generate a plurality of patches representing the first point cloud model and the second point cloud model;
place the plurality of patches into a two-dimensional image, to pack the plurality of patches as a video frame;
encode the video frame of the plurality of patches; and
multiplex the encoded video frame of the plurality of patches and the transform information representing the parameter of the shifting.
