1. A three-dimensional data encoding method comprising:
determining whether a prediction mode to which a predicted value of information to be encoded is not assigned is present within a plurality of prediction modes;
identifying, when a prediction mode to which the predicted value is not assigned is present, a new predicted value to be assigned to the prediction mode to which the predicted value is not assigned;
calculating a prediction residual which is a difference between the information to be encoded and a predicted value corresponding to a prediction mode selected from among the plurality of prediction modes; and
generating a bitstream including a value indicating the prediction mode selected and the prediction residual.
