1. An image processing apparatus comprising:
circuitry configured to
perform a filter process on point cloud data using a representative value of the point cloud data for each local region obtained by dividing a three-dimensional space;
encode a two-dimensional plane image on which the point cloud data subjected to the filter process is projected;
generate a bitstream including information regarding the local region that includes information regarding a size or a size and a shape of the local region;
determine whether a current position in an occupancy map of the point cloud data is located at an end of a patch in the occupancy map;
set, on a basis of determination that the current position is located at the end of the patch, a processing range of the filter process to the current position; and
exclude, on a basis of determination that the current position is not located at the end of the patch, the current position from the filter process.
