Claim Text:
1. A method for processing image data corresponding to temporally successive motions of an object, the method comprising: adjusting a range of a first occlusion region which is estimated according to whether position changes occur in sub-blocks forming temporally successive first and second frames among image frames which display the motions of the object, by using Motion Vectors (MVs) mapped to the sub-blocks; and detecting a second occlusion region of a third frame which displays the object that moves between the first frame and the second frame, by using the adjusted range of the first occlusion region, wherein the adjusting of the range of the first occlusion region comprises: mapping, to a first sub-block included in the range of the first occlusion region, a temporary MV which has a trajectory in a same direction as an MV of a sub-block which is closest to the first sub-block among sub-blocks located in a region outside the first occlusion region; and if a difference between a random MV of the first sub-block with the temporary MV exceeds a predetermined threshold, excluding the first sub-block from the range of the first occlusion region.
