1. A three-dimensional (3D) image data processing apparatus comprising: a 3D image data obtaining unit to obtain, using a processor, 3D image data; an integrated format data generating unit to integrate, using a processor, native format data of the 3D image data and common format data generated by using the 3D image data to generate integrated format data; and an integrated format data processing unit to process, using a processor, the integrated format data according to an image processing algorithm, wherein the integrated format data processing unit determines whether a native image processing algorithm with respect to the native format data of the integrated format data is present or absent, wherein when the native image processing algorithm is present, the integrated format data processing unit processes the native format data of the integrated format data according to the native image processing algorithm, and wherein when the native image processing algorithm with respect to the native format data is absent, the integrated format data processing unit processes the common format data of the integrated format data according to a common image processing algorithm.
