1. A three-dimensional image processing apparatus for reconstructing a three-dimensional image of an object, comprising: a three-dimensional model generator which generates, from the object, a three-dimensional model which is data for reconstructing the three-dimensional image of the object; and a three-dimensional image synthesizer which synthesizes the three-dimensional image from the three-dimensional model, and displays the three-dimensional image, wherein the three-dimensional model generator comprises: a three-dimensional shape acquisition unit which acquires three-dimensional data relating to a shape of the object, a surface attribute acquisition unit which acquires surface attribute data relating to a surface attribute of the object, and a three-dimensional data integrator which generates the three-dimensional model by integrating the three-dimensional data acquired by the three-dimensional shape acquisition unit and the surface attribute data acquired by the surface attribute acquisition unit, wherein the three-dimensional image processing apparatus changes an image capturing environment to take an image data of an object according to an incoming signal.
