1. A 3D image special effects apparatus for creating special effects on a 3D image including a first image and a second image having disparity, the apparatus comprising: a range specification receiving unit capable of receiving an input of a specified range of the first image on which the special effects are created; a first block division unit capable of dividing the specified range into a plurality of first image blocks; a first special effects unit capable of creating the special effects on each of the plurality of the first image blocks; a block matching unit capable of determining an image from the second image which corresponds to an image of the each of the plurality of the first image blocks and deriving a parallax vector which represents a directionality and a magnitude of parallax between the first image blocks and the corresponding image; a second block division unit capable of determining a plurality of second image blocks on the second image in accordance with the parallax vector, the second image blocks corresponding to the plurality of first image blocks; and a second special effects unit capable of creating the special effects on the determined plurality of second image blocks.
