Claim 7:
8. The three-dimensional data decoding method according to claim 5, further comprising:
obtaining encoded geometry information and a second quantization parameter from the bitstream, the encoded geometry information being generated by encoding items of geometry information of the three-dimensional points;
transforming the second quantization parameter to a fourth scale value, based on a second table indicating a correspondence between a plurality of values of the second quantization parameter and a plurality of values of the fourth scale value, the second table being shared between the first decoding scheme and the second decoding scheme;
performing decoding including a second inverse quantization process to obtain the items of geometry information, the second inverse quantization process being a process of multiplying, by the fourth scale value, each of second quantization coefficients based on the encoded geometry information.
