Classification: CPC G | IPC G

Claim 15:
16. A device for decoding a three-dimensional image including a point cloud, the device comprising:
a receiver configured to receive a bitstream; and
at least one processor configured to:
obtain, from the bitstream, information related to down-sampling and data in which a two-dimensional image is compressed,
up-scale at least one down-sampled patch included in the two-dimensional image based on the information related to the down-sampling, and
reconstruct the point cloud by restoring color information and position information of points based on the up-scaled two-dimensional image,

wherein the information related to the down-sampling includes a predefined rule, and
wherein the predefined rule is a table indicating a size of blocks into which the at least one patch is divided and indicating a predefined position at which a point is preserved from the blocks.
