         2 . The local multi-view image display apparatus of  claim 1 , wherein the location tracking unit tracks a location of a head of the observer, and the display unit displays the multi-view three-dimensional input image on the tracked location of the head. 
     
     
         3 . The local multi-view image display apparatus of  claim 2 , wherein the display unit comprises:
 a view matching unit to match at least one view among the plurality of views of the multi-view three-dimensional input image with at least one view corresponding to the tracked location of the head from among a plurality of views that may be displayed by the local multi-view image display apparatus.   
     
     
         4 . The local multi-view image display apparatus of  claim 3 , wherein the display unit displays the multi-view three-dimensional input image through the at least one view corresponding to the tracked location of the head. 
     
     
         5 . The local multi-view image display apparatus of  claim 2 , further comprising:
 a variation measurement unit to measure a motion variation of the head based on the tracking result of the location tracking unit, when the location of the head changes;   a determination unit to compare the measured motion variation with a threshold value, and to determine whether the measured motion variation is greater than the threshold; and   a transmission unit to transmit a tracking result of the changed location of the head to the display unit, when the measured motion variation is greater than the threshold value, the changed location of the head being tracked by the location tracking unit.   
     
     
         6 . The local multi-view image display apparatus of  claim 5 , wherein the display unit displays the multi-view three-dimensional input image on the changed location of the head, when the tracking result of the changed location of the head is received from the transmission unit. 
     
     
         7 . The local multi-view image display apparatus of  claim 5 , wherein the threshold value comprises a predetermined number of views of the multi-view three-dimensional input image. 
     
     
         8 . The local multi-view image display apparatus of  claim 2 , wherein the location tracking unit tracks the location of the head in real time. 
     
     
         9 . The local multi-view image display apparatus of  claim 3 , wherein a number of the plurality of views that may be displayed by the local multi-view image display apparatus is greater than a number of the plurality of views of the multi-view input image. 
     
     
         10 . A local multi-view image display method of a local multi-view image display apparatus, the local multi-view image display method comprising:
 tracking a location of an observer using a location tracking unit; and   locally displaying a multi-view three-dimensional input image on the tracked location based on a tracking result of the location tracking unit, and   wherein the multi-view three-dimensional input image comprises a plurality of views which are sequential.   
     
     
         11 . The local multi-view image display method of  claim 10 , wherein the tracking tracks a location of a head of the observer, and the locally displaying displays the multi-view three-dimensional input image on the tracked location of the head. 
     
     
         12 . The local multi-view image display method of  claim 11 , wherein the locally displaying comprising:
 matching at least one view among the plurality of views of the multi-view three-dimensional input image with at least one view corresponding to the tracked location of the head from among a plurality of views that may be displayed by the local multi-view image display apparatus; and   displaying the multi-view three-dimensional input image through the at least one view corresponding to the tracked location of the head.   
     
     
         13 . The local multi-view image display method of  claim 11 , further comprising:
 measuring a motion variation of the head based on the tracking result of the location tracking unit, when the location of the head changes; and   comparing the measured motion variation with a threshold value, and determining whether the measured motion variation is greater than the threshold value.   
     
     
         14 . The local multi-view image display method of  claim 13 , wherein the locally displaying displays the multi-view three-dimensional input image on the changed location of the head based on a tracking result of the changed location of the head, when the measured motion variation is greater than the threshold, the changed location of the head being tracked by the location tracking unit. 
     
     
         15 . The local multi-view image display method of  claim 13 , wherein the threshold value comprises a predetermined number of views of the multi-view three-dimensional input image. 
     
     
         16 . The local multi-view image display method of  claim 12 , wherein a number of the plurality of views that may be displayed by the local multi-view image display apparatus is greater than a number of the plurality of views of the multi-view three-dimensional input image. 
     
     
         17 . A computer-readable recording medium storing a program for implementing a local multi-view image display method of a local multi-view image display apparatus, the local multi-view image display method comprising:
