Abstract

The encoding device (1580) includes a circuit (1581) and a memory (1582) connected to the circuit (1581). The circuit (1581) acquires multiple three-dimensional data generation models during operation, encodes the multiple three-dimensional data generation models to generate a bit stream. The multiple three-dimensional data generation models include a first three-dimensional data generation model corresponding to a first time and a second three-dimensional data generation model corresponding to a second time. When the multiple three-dimensional data generation models are respectively input with viewpoint information including viewpoint and viewing direction and potential codes set for the time corresponding to the multiple three-dimensional data generation models, they output a two-dimensional image of the subject at the time when the potential code is set, observed from the viewpoint and viewing direction. The bit stream contains the potential code.
