2. The apparatus of claim 1, wherein the 3D parameter of the obtained image data comprises at least one of the number of visual points (NumofStereoPair) included in the data, an index (PairedViewlD[]) of a visual point forming a Stereo Pairing with a current visual point, a width of a boundary occlusion region (BoundaryOcclusionWidth) of the current visual point compared to a reference visual point, and a direction (Occlusion Direction) where a boundary occlusion region occurs.

3. An apparatus for reproducing three dimensional (3D) data in a mobile terminal, the apparatus comprising:

a 3D data manager for reading a start address of a block where image data for at least two visual points are separated and stored, analyzing a parameter of 3D data to reproduce in each block of the start address, determining a visual point included in the 3D data using the analyzed parameter, and reproducing the determined visual point to provide a 3D effect.

4. The apparatus of claim 3, wherein the 3D data manager analyzes at least one of the number of visual points (NumofStereoPair) included in the 3D data, an index (PairedViewID[]) of a visual point forming a Stereo Pairing with a current visual point, a width of a boundary occlusion region (BoundaryOcclusionWidth) of the current visual point compared to a reference visual point, and a direction (Occlusion Direction) where a boundary occlusion region occurs to analyze a 3D parameter of the 3D data to reproduce in each block of the start address.

5. The apparatus of claim 3, wherein the 3D data manager increases a user'"'"'s a 3D effect depending on a size of a display, or reduces a user'"'"'s visual fatigue depending on the size of the display to reproduce the determined visual point and provide the 3D effect.

6. The apparatus of claim 3, wherein the 3D data manager removes a boundary occlusion region to reduce a user'"'"'s visual fatigue and reproduces the determined visual point to provide a 3D effect.

7. The apparatus of claim 5, wherein when the size of the display is small, the 3D data manager reproduces data of an auxiliary visual point whose disparity with a reference visual point is long to increase a user'"'"'s 3D effect depending on the size of the display.

8. The apparatus of claim 5, wherein when the size of the display is large, the 3D data manager reproduces data of an auxiliary visual point whose disparity with a reference visual point is short to reduce a user'"'"'s visual fatigue depending on the size of the display.
