Method for dividing the image block and Apparatus thereof

PURPOSE: An image block segmentation method and an apparatus therefor are provided to remove flickering phenomenon generated when synthesizing middle images necessary for the reproduction process of a 3D image. CONSTITUTION: An LMB(Large Macro Block) segmentation discriminating unit(30) sets a plurality of segmentation threshold values necessary for segmenting a macro block of an image frame into sub blocks, and discriminates whether the macro block is segmented. An MSB(Middle Sub Block) segmentation discriminating unit(31) sets a plurality of segmentation threshold values necessary for segmenting each sub block into different sub blocks, and discriminates whether the sub block is segmented.
