1. An image processing apparatus comprising:
circuitry configured to:
divide a three-dimensional space containing point cloud data into a plurality of grids;
derive, for the grids, respective representative values of the point cloud data;
perform a filter process on the point cloud data by performing trilinear smoothing of the respective representative values of the grid; and
encode a two-dimensional plane image on which the point cloud data subjected to the filter process, and generate a bitstream related to the encoded two-dimensional plane image.
