摘要

A three-dimensional data encoding method includes: quantizing geometry information of each of three-dimensional points, using a first quantization parameter (S5391); quantizing a first luminance using a second quantization parameter and quantizing a first chrominance using a third quantization parameter, the first luminance and the first chrominance indicating a first color among attribute information of each of the three-dimensional points (S5392); and generating a bitstream including the geometry information quantized, the first luminance quantized, the first chrominance quantized, the first quantization parameter, the second quantization parameter, and a first difference between the second quantization parameter and the third quantization parameter (S5393).
