Claim One:
1. A method of estimating a disparity in a multiview image display apparatus, the method comprising: performing image scaling on a first view image frame included in a plurality of first view image frames and a second view image frame included in a plurality of second view image frames, wherein the scaled first view image frame and the scaled second view image frame have a certain resolution; identifying a matching block matching with a reference block of the scaled first view image frame from among a plurality of matching blocks of the scaled second view image frame, by comparing the plurality of matching blocks with the reference block; and estimating a disparity between the first view image frame and the second view image frame, based on a disparity between the reference block and the matching block, wherein an overlapping degree of the plurality of matching blocks varies according to the certain resolution, wherein the first view image frame and the second view image frame are based on a different view, and wherein if the first view image frame is a first image frame among the plurality of first view image frames, the certain resolution is equal to or lower than a resolution for scaling remaining image frames of the plurality of first view image frames.
